The Ministry of Defence have confirmed that the new Tempest jet will not be carrier capable and will be a purely land based aircraft.
While many already knew this, there had been little in the way of official confirmation until James Heappey, the Parliamentary Under-Secretary of State for Defence responded to a written Parliamentary question from Tobias Ellwood.
Ellwood, Chair of the Defence Committee, asked:
“To ask the Secretary of State for Defence, what plans he has for Tempest to operate at sea.”
Jeremy Quin responded:
“The UK’s Combat Air strategy operates across a broad force mix. The maritime combat air role is undertaken by the UK’s F35B Lightning aircraft from the UK’s Queen Elizabeth Class Aircraft Carriers and will continue to do so for the foreseeable future. The Future Combat Air System (FCAS), seeks to replace Typhoon once it retires from service and provide an international next generation Combat Air System, and high tempo military capabilities for decades to come.”
What is Tempest?
Tempest is the RAF’s next generation combat aircraft, coming into service from 2035 to replace the Typhoon.

Will drones operate from the carriers?
According to a presentation on the ‘Future Maritime Aviation Force’, the Royal Navy is planning to develop carrier launched drones capable of combat, airborne early warning and aerial refuelling.
Slides make mention of “adding mass” to the Carrier Wing with additional F-35BS and a medium FWUAS (these will be Vixen fixed wing drones, Harry Lye has taken a look at those here).
The Royal Air Force too is already working on a new Lightweight Affordable Novel Combat Aircraft (LANCA) concept through Team Mosquito.
The land-based Mosquito drone will begin a flight-test programme in 2023. There is no word however when the sea-based Vixen drone will start flight tests.
How will the drones be launched at sea?
Earlier, we reported that the Ministry of Defence is currently seeking information on the potential for industry provide assisted launch and arrested recover systems for a range of air vehicles, which would be suitable to fit to a vessel within 3 – 5 years.
The Ministry of Defence say that this request for information is to support the development of the Royal Navy’s Future Maritime Aviation Force (a presentation on which is where the slide above came from) with potential for use with both crewed and un-crewed air vehicles.
The Ministry of Defence add that it is looking to assess the availability of electromagnetic catapult, and arrestor wire systems for the launch and recovery of air vehicles.
i can’t say i am surprised, as we do not have cats and traps, if we did, it might be a whole different ball game, but with defence budgets being scrutinised and money wasted on so called upgrades that never happen or get cancelled would we ever be able, to afford to convert the 2 carriers to cats and traps, plus like mentioned drones are seemingly the way forward, as drones will become cheaper to build….
I don’t think that we ever going to happen.
The full scale EMALS type CATs’n’TRAPs is now a sideshow.
Drones are the future and wether by design or happenstance the right decisions have been made.
The uk defence budget is one of the largest in the world I think it could if it felt it needed to convert them to cat and trap but the uk has decided not to go down that road in reality the uk has overseas territories that can be used to cover large parts of the globe carriers are for that time where we can’t cover with our land based aircraft
it maybe large but it is not managed well at all, we have our nuclear deterrent paid for out of it, never used to be until Osbourne became chancellor, but we spend a fortune out of it settling claims, for injured service personnel or civil workers with repetitive strain injuries along with tank chasing solicitors, there is also legal bills defending veterans over this shambles of incidents during op banner, which should never been allowed from the get go, then there are the pension’s, so add all that up that is a massive chunk of money spent from a budget long before we pay wages and buy equipment..
I guess this now clears up some of the fog, and we have a clearer direction!
Changes little.
My eye is on Vixen and Mosquito.
Which begs the question, as the carriers will outlive the F35, what will it be replaced by or are we essentially commuting ourselves to son of F35?
Yes and when the F35 retire will it be solely drones as a replacement or will we have to rely on the USMC wanting procurement for a manned replacement ?
I wouldn’t be so sure it will outlive F35. They will still be producing F35 in 25 years time unless the B varient gets cut by the US.
That will put F35 out of service date in the 2060s.
Last scheduled order for F35 is 2035, around the same time as first scheduled order for Tempest.
Let’s be honest there is a very good chance that the future is unmanned platform and the F35/ Tempest will be the last manned fighters.
I would tend to agree that the future will be drone centred and manned aircraft will be thin on the ground.
But we would still need manned helicopters for troop deployment and logistics.
The helicopter mission for troop deployment and cargo movement is probably the easiest to turn into an autonomous system – no ethics argument and no autonomous killing machines. I think we will always see a mix of crewed and uncrewed combat air aircraft – the balance of the 2 is still up for debate, though.
As BB85 points out, the F35B is probably going to be in service for the next 40 years. By that time the current carriers will be approaching the end of their useful lives anyway. So we need to start developing replacements based around unmanned platforms in the 2040s which can take over from the QE class in the 2060s.
They won’t outlive F-35. Carriers have a 50 year life max, so out to 2070. US is planning at present to have them in service until 2070 at a minimum.
Sorry to labour the point, but it is then back to my original arguments elsewhere for an interim “grab” of any late-fit AV8Bs/Harriers going spare to cover for the next 3-5-years, and then for the UK to develop a “Soooooper HARRIER III” that is maybe based around a twin-Pegasus type of powerplant to go on the UK QE and PoW.
My day job is commercial drones. Unless you are going to have shed loads of pilots sitting in a (errrr…) shed somewhere controlling them, then I will be shocked if we have truly autonomous military drones licensed to kill within the next couple of decades.
Why would we develop a VTOL aircraft based on Harrier or Pegasus, 50 year old designs? There will probably be no other western VTOL combat aircraft until the F35B goes out of service. There may be no others in the whole world as the Russians and Chinese don’t seem to be developing one.
…learning the design lessons from history and building upon them.
Having got 2x Aircraft Carriers, what are we going to stick on them as the F35B is phased out in the future? Just trying to look ahead.
“Son of F35B” presumably. By then we will have had even more lessons learned from F35B than Harrier, so why not build upon that?
…or both. Longer range would be good 🙂
Even a twin engined F35B with longer range, speedy and more payload? A bit of a mini-naval Tempest?
A rebuild for a harrier is a step backward. we are looking 35+years ahead. I think the Tempest is likely too big for carrier.
Who knows where technology is going in 20 years. In 20 years if we want carriers that’s when we will start designing them and what to fly off them. Meantime who k owd what weapons and computers will be on our F35s.
…not a rebuild. Just build on the lessons learnt from both and help sustain UK design and manufacture, rather than all the £dosh going out of the country again.
Hi. It would simply take away precious funds from kit we actually need. If we have spare cash, then we will buy more F35’s instead of wasting vast sums of money on a harrier, old or new. Bringing even a small number of Harriers back into service would cost a huge sum of money. Pilot and ground crew training, logistics and infrastructure, maintenance, ground equipment, basing. It’s a total non starter. Harrier was fantastic In it’s day, but F35 is in a different league. F16’s are still being produced, Likelihood is F35 will still be in production in 40 years time.
Lessons learnt?….are you aware of how F-35 systems, avionics and flight controls were actually fitted to a Harrier and test flown into oblivion before the Lightning even made serial production?
*how many
Won’t need aircraft carries in 20-30 years let alone 50. The new reaction engine sabre engine being developed in UK and soon to have it its first small scale engine prototype run. Will be able to put a fighter anywhere on planet in less than 5 hours at Mk5. So after tempest they will be no need to have a carrier, manned or unmanned drones will simply take off from UK and strike anywhere on planet.
Sounds futuristic but you are Certainly thinking in the right direction reaction engined fighters are probably more likely than large carriers that’s for sure 50 years hence they will simply be impossible to defend I suspect. Small drone versions maybe.
Hmmm…
Our carriers do more than carry fixed wing aircraft – they provide Task Force C2, can do HADR, carry commandos and helos etc.
I think that Carriers will about for sometime with or without fixed wing aircraft They will always be used for helicopters and deployment of troops
At Rolls Royce in Bristol they have in their museum/gallery the next generation of the Pegasus engine. This was the “3 poster” version where the Pegasus’s two hot end exhaust ducts were combined as a single outlet with reheat, as per a normal jet. This was the proposed RR engine for the early JSF program. The engine was also a proposal for the next gen Harrier if the JSF failed to work as a STOVL aircraft, this came after the AV-16 idea.
If I remember correctly, it used the core of the EJ200, but put a whacking great 1st stage on it for the cold air ducts. The predicted thrust was about the same as the current F135 engine used in the F35. Would this “Super Pegasus” have been a better arrangement than the lift fan and F135 combination used in the F35B. Personally, I think so as the cold air ducts would have been used 100% of the time, unlike the lift fan. Therefore no dead weight would be carried and the space used by a lift fan could be used as an additional fuel tank.
The answer as to why that idea died a death decades ago is your “whacking great 1st stage”.
That makes the aircraft insanely fat, and completely compromises it for any kind of efficient cruise and transonic/supersonic performance – noting the F35 is to replace F18/16 class aircraft and longer range was wanted vs notriously short legged Harrier. Its also a one trick pony for a STOVL aircraft.
STOVL is about thrust. Thrust is basically:
Mass flow rate x velocity change.
To get thrust you can (a) move a little bit of air a lot faster (turbojet), or (b) move a lot of air but not as fast (turbofan).
For STOVL, turbojets dont work as they are too noisy, have too destructive jet effects (on the ground and the aircraft) and they ingest their own efflux, about 1degree C of inlet rise causes 100lb of thrust loss as you cant raise the temp in the engine higher (its already as high as it can be before it melts) so the energy you are adding is reduced.
Turbofans are the only way. Harrier/Pegasus genius was it had the colder fan air acting as a blocker to the hot air at the back from being ingested. You could also direct all the thrust aft or down.
Massive downside was that meant the entire engine is sized and optimised around one point – VTO/VL, and to shift the volume of air, had to be very wide. Getting on for 3x cockpit width wide!
Hence why it was so compromised for cruise etc. The engine also had to go at the centre of gravity (CG) which is the worst place for it structurally and for fking up avionics and fueslage volume.
F35 puts the engine at the back where it should be (a fixed unchanging weight, so fuel/weapons which are variable can thus sit near the CG). The lift fan acts as that high mass flow generator for STOVL but is basically out of the way for the rest of the flight and the core engine is sized for that. The same engine as in 1000s of A/C variants. The lift fan blocks the hot air as before, albeit cant be fully deflected aft. Yes it costs some fueslage volume but that is liveable with.
It really is the optimum.
This was all done to death in the 80s and 90s, there are good reasons they ended up where they did (although F35 isnt perfect – roll posts Im looking at you…)
The Harrier was a great aircraft, but so was the Spitfire – neither could last forever.
Spot on!
Yes, you are quite correct. The Pegasus is basically a high bypass ratio turbofan where it uses cold mass flow in conjunction with high velocity hot flow to generate thrust that is greater than the aircraft’s weight to achieve vertical lift
I’m trying to remember what the RR tripod engine was called. It was a fixed ratio high bypass turbofan, much like Pegasus. Unlike one of the proposals for Pegasus, it didn’t heat up the air exiting the cold exhausts through plenum chamber burning, which was supposed to be used for the proposed AV-16 “Super Harrier”. The tripod style arrangement would necessitates an unusual airframe such as the P1214/1216 or the split tail of the Yak 141. Routing the cold air to ducts similar to the F35’s would have prevented the aircraft from “viffing”, whereas using the Harrier style swiveling ducts would allow it.
The design was supposed to meet the requirements for the future advanced STOVL aircraft, that became the future joint combat aircraft, that then became the joint strike fighter, i.e. which was won by the X35B.
As you quite rightly say, the large diameter 1st stage of a Pegasus type engine would make designing a stealthy airframe quite difficult. At the time of the proposal it wasn’t a consideration. The F117 was still a black project, so faceting wasn’t widely known and embedded radar absorbent materials were beginning to be researched.
The requirement was for a fleet interceptor and a close air support aircraft. Would the P1214/1214 been a better aircraft than a F35B. No, as it would have been a generation apart. This aircraft was in the same time frame as the Typhoon, so a pre-stealth 4th generation aircraft.
The Harrier and Pegasus combination was a fantastic keep it simple stupid solution to a very technical problem. How do you make an aircraft that can take off and land vertically, then fly like a normal aircraft whilst keeping weight in check. For an aircraft to survive in today’s cluttered air defence system environment, stealth is key, something a Harrier variant would struggle to meet.
Focusing on lack of stealth of a fat Pegasus type engine ignores it’s draggy nature which limits range and max speed which are of equal importance.
Face up to it, the Pegasus/Harrier approach died with “Monica”.
Agree, you would have to make significant compromises to make sure the aircraft could achieve sustained supersonic flight.
Exactly. Thanks for the summary DaveyB.
I remember in the earlier days when RR were trying to master (unsuccessfully) plenum chamber burning for re-heat.
Some sort of F33B/F22 vectored thrust for the main motive force, but with the use of a “cool” front end for STOL is a much more elegant solution than the F35B.
The problem with the original Pegasus is the big fan on the front so only subsonic and not very stealthy. Maybe a Sooooper-Pegasus II could be a great evolution from this.
RR “mastered” plenum re-heat. The technology died for reasons that had nothing to do with them i.e. ground erosion & hot gas re ingestion.
Thanks. Ron5. I must have been behind the curve for that bit.
Yep, hot gas ingestion was the main problem. The Harrier they used for the trials also suffered from “suck down”. This was where the hot jet exhaust caused a very low pressure directly below the airframe and made the aircraft sink, applying more power made it worse. They had to use really large strakes to try and mitigate the issue, but they never really solved it.
Core of EJ200 has about 60% of the power of the core of F135 so this makes no sense.
Also, afterburner that would operate without the bypass air would be much weaker.
This hype is totally separated from reality.
Where did you get the information on the F135’s core being 40% more powerful than the EJ200’s? As far as I can tell the F135 is about 15 to 20% larger in diameter than the EJ200. This would not equate to a significantly larger mass flow through the core of the size you’ve quoted. However, the F135 has a larger bypass ratio of 0.57 compared to the EJ’s 0.40. This would suggest that the F135 has a much larger first stage, hence the larger diameter. The larger diameter and larger mass flow would develop more power on a one for one comparison, but means the engine cannot operate at very high altitudes, unlike the EJ have a much lower by-pass ratio.
The 3 poster engine used a 1st stage similar in size to the later Pegasus engines. So its by-pass ratio would have been significantly greater than 0.50. The larger 1st stage would have generated a significant proportion of the thrust, same as the Pegasus. The prototype engine in the gallery did not show if it used plenum chamber burners, which would have contributed to aircraft’s supersonic abilities. It would have been interesting to see how they controlled the intake air for such a large engine, as this wasn’t shown or mentioned!
Correct using an afterburner/reheat chamber to chuck more fuel into a turbojets exhaust stream will have a less dramatic effect, as there is less useable oxygen, compared to using the untouched bypass stream from a turbofan.
The proposed EJ230 is supposed to use a larger diameter core than the 200 version. It would be interesting to see if they have also increased the by-pass ratio. The larger engine would need a few frame modifications to make it fit a Typhoon. But then it depends if they’re making it as a variable cycle engine, that combines the low level mass flow of a turbofan and the high level attributes of a turbojet?
That is pretty much my point. The unmanned aircraft solution has been around since the 60s and with as many engineers trying to perfect drones, there are as many engineers try to figure out how to mess with them , unless you want to take the human out of the loop ( ethical mine field) then the days of a fully autonomous airforce are very far away. You still need to be able to pass instruction and they will always be vulnerable because of it.
Whether the F35 will out live the carrier is a moot point given that the military press is awash with critism of the F35 and rumours of the USAF wanting to develop a less stealth alternative, the so called Kingsnake!!. I think part of the F35 critism is they are measuring it against antiquated bench marks.
Dropping the Navalised Tempest option this early may prove to be a mistake, but who knows we may have developed any gravity by then.
Before everyone laughs, I sat in a lecture at university in 1988 where the eminent to guest speak said we would never break a million devices on a chip. It took them two years.
I sat in another lecture that said that unless we lay fibre optics to everyone’s home we would never surpass 100 kb/s , we are pushing 50 meg plus down copper cable layed decades ago!!
Yes, Michael and that’s the point to me. R & D will always produce results, even though there will be misses along the way. Typhoon 1 is nothing like Typhoon 100 in many different ways. The same will be true of the F35. In 10 years time it probably will be unrecognizable from F35 UK 1 – one of the main reasons for the sensible decision to slow buy.
That system was rejected because it is inherently un stealthy. It literally signals its position to sensors.
Yes. I seem recall that the lift fan is inherently a better option but happy to be contradicted.
One of its many advantages is that the lift fan approach separates vertical lift thrust from main engine thrust. With Harrier/Monica type designs, any increase in STOVL performance has to come from very expensive main engine thrust upgrades rather than much cheaper lift fan improvements.
The way research is going drones will be a major factor in future combat on land sea and air, less boots on the ground
This twin pegasus powerplant, for a tactical fighter bomber – you realise it’ll be as wide as a Hercules with drag to match?
We do have loads of pilots sitting in sheds, and are recruiting and training even more.
Why would you waste money training 1000s of people, hundreds of millions on spare parts and tools, billions on support contracts with industry (for parts etc) on ancient Harriers when if we had that money, we could spend a fraction and have more military effect at far greater efficiency from just having some more F35s? Noting we dont have the money or the people anyway.
F35 -is- the Soooper Harrier. It looks quite different because things moved on. But that is exactly what it is, the end result from wanting a better Harrier type.
And you think we should do it again, in 3-5 years? I love the Harrier as much as any proper Aerobautical Englishman, but let it go!
Amen to that.
Back in the late 60’s Dornier tried the twin Pegasus approach with their Do-31 light transport aircraft. It achieved flight and even did hovering and vertical take-off and landings. But to do so it needed 8 additional vertical lift jets. It also suffered from lots of drag. due to large sponsons that housed the lift jet under the wings. It was eventually cancelled by the West German Government due to costs and a lack of interest from other NATO countries.
Good decision. There are questions about the affordability of the project as is, let alone with the complexity of developing it for carrier ops.
Good point. When the MOD go for open ended do everything projects they never materialise and if they do are years late and massively over budget. By working out the specific requirement at the outset hopefully, this time around, this can be avoided.
At the recent defence review the Navy got it’s carriers and new escorts, the Army has got it’s replacement vehicles and artillery and the RAF FCAS. In fact the RAF didn’t get much out of the review and I suspect their ‘price’ was a guarantee that Tempest & Mosquito happen. If the Navy get Vixen that’s great but let’s not screw up FCAS by worrying about a replacement for F35 which is due to be in service for 30 years. I very much think the F35 replacement, when it comes, will be an UAV.
Rob, sounds like you think the army did well out of defence review. I disagree – cut from 82,000 to 70,000, tank fleet cut again (savagely) with an upgrade taking 9 years to deliver (FOC), Warrior upgrade cancelled and the vehicles allowed to wear out, no upgrade for AS90 but a ‘jam tomorrow’ replacement promised.
Hi Levi,
The problem with carrier ops is primarily the landing.
When landing on terrafirma you obviously have a long strip of thick concrete to put down on. The length is the key point as it gives you the space to flare out just before you plant the main gear down onto the runway. The problem for carrier operations with flaring your approach is that you increase the angle of attack of the wing, increasing lift until the speed bleeds off. This initial increase in lift can be quite significant if your airspeed is even just a few knots above optimum or, worse, if you encounter a gust of wind. The result is that you float down the runway with your undercarriage a few feet off the ground. Something I have experience often when I was flying.
If this was to happen on a carrier landing you would ‘float’ right off the end of the flight deck with your engine on a low power setting. Turbines take awhile to spool up so the chances are you’ll end up in the sea with 60,000 tons of aircraft carrier coming towards you at 30+knots. Not good. This has happened to a USN carrier which apparently ended up with an F14 (I think) shaped hole in the bow.
So the way around this is not to flare out on landing. In effect you fly straight into the deck. The forces are huge compared to a land based landing. These increased loadings require a much bigger and heavier undercarriage and a hugely strengthened central fuselage which has a big knock on impact on other factors and systems. The extra weight requires more power, for example, and probably a reduced payload as well. In effect a new airframe / engine combination entirely.
Sorry if you already knew this, but many do not appreciate the engineering challenges of landing on any surface, let alone a carrier’s moving deck.
Cheers CR
My only fear here is, if a labour government comes in they will do to the Tempest what they did to the TSR2. Naturally the money saved will be spent on MPs second homes, their John Lewis accounts employing BBC (think about it) rent boys and of funding third world countries buy Mercedes programs
Hi, please keep in mind our comment moderation policy with regards to party politics. This comment should serve as a warning with regards to future posts.
The last time a new Labour government. came into power was in 1997, At the time the Typhoon was still in development, running behind over budget, but it was Not cancelled.

I don’t think they could as it was a tri-nation project in which we were the largest investor, but saying that the RAF under instructions from the party in power did try to remove the 27 mm cannon in which to save money, or was it because it could kill somebody?
Then after spending millions (Including at looking at filling the gap inside the plane with concrete) they decided to keep the gun, but just not issue ammo, thankfully that brainwave was put out to pasture
I forgotten the issue with the cannon. They most likely tried to save a bit of money!
Possibly, but it was not “Set in Concrete” 😁
Yes, that’s exactly what they tried to do. Same old story over and over Well if Tempest is purely land based (why can’t we learn from the French and develop aircraft that can operate at Sea and on land??) then the RAF better hand all the F35Bs over to the Navy.
Blimey mate…. I got all excited when you said “All the F35b’s” then I realised how many we actually have…….😂
Numbers are a lot smaller than they should be at the moment, but they will grow……
They will grow mate……. 48 eventually by all accounts, just a shame we’ll not get the other 90 though. 😥
We may still order all 138, but the minimum number will be around 90. The current buy rate does ensure we get the up-to-date versions instead of having to spend a fortune updating airframes or retiring them.like the Tranche 1 Typhoons (although that’s just an excuse – they perform perfectly well in the AIr Defence role).
90 ? Please can you share your source on this figure mate…… I’d love to see the time frame and confirmed order schedule.
It was in the Defence review. Although acknowledged that the UK would probably not buy all 138(although that wasn’t actually confirmed), it was confirmed that 48 have been ordered to date with a further order to follow probably totalling between 80 and 90. As for delivery dates, thats anybodys guess. The only reason for this is a shift towards Tempest, although it remains to be seen just what happens with that.
The USAFs next gen plane will not be marinised. The USN will develop a separate carrier plane. Indeed they the USN have always built separate planes. The F18 is for carriers, as was the F14. There are good reasons for that .
The F35 is an exception. I can only guess but the French German 6th gen plane, if it is indeed going to be 6th gen, will have expensive compromises, and that only for the benefit of a couple of dozen planes.
Sorry but no.
The Rafale has not “expensive compromises” Vs Typhoon.
The compromises are actually to have a carrier with cats & traps.
If you do you make the design from scratch with that in mind, and after the full Navy version you can derive a ligther land base version.
By the way even the F18 SH wich was not supposed to be a land based aircraft is now a contender for Swiss, Finland & Canadian competitions, and a serious one !
But for sure if you start by : no need for cats & traps, it’s costly and we will have the F35B.
Then you realise that maybe the F35B IS costly and having not cats & traps make you a slave to it.
Then because finally the F35 is not a suitable solution to replace the Typhoon you launch the Tempest, but you already have brand new carriers with no cats & traps.
So you can’t make a Navy version of the Tempest.
But you still want drones able to be launched in the future from your carriers … so you are looking for a solution to finally have cats & traps !!!
At this point every one is chasing Benny Hill…
Because we’ve witnessed first hand that combining clashing requirements usually results in inferior final products. If we want Tempest to actually be good enough to compete, it needs to remain focused on land operations.
If we want to develop a carrier replacement in future, we can use experience and common components from Tempest on a purpose-built carrier aircraft.
Hi Callum,
Yup, develop an airframe capable of taking the extra stresses of carrier ops and fill it with as much of the systems from Tempest as you can / is appropriate. The systems is where most of the cost is these days, so it will help to spread part of the development cost of Tempest as well.
Of course, the effectiveness of this approach would depend on the requirements of the two aircraft being sufficient close to make the systems applicable to both, a trade off in effect.
Cheers CR
Well I think the fact that 3 countries decided to side with the UK and none with the French the last time that debate was had i.e. Typhoon/Rafale and the weight restrictions inherent in that decision, tends to suggest that most tended to disagree with your advice. Hey maybe things have changed but I doubt it for a multi role aircraft certainly where so much more will be needed than even back then. Will be interesting to see what happens with the Franco/German program and whether similar arguments between the parties break out. However I note that the proposed new French carrier will be as big or even a bit bigger that QE/PofW so one presumes weight/size limitations on its aircraft won’t be so restrictive.
The cannon was to be deleted so as to save the money supporting and operating it. Turned out that came at an upfront cost because its weight was baked into the flight control system so that would need redesigning and then testing at time and cost. Or designing something that perfectly replciated it. So letting it sit in the plane inert solved that. But then the airworthiness aspect of a bit of unmaintained kit on the aeroplane kicked in and so it had to be maintained anyway. In which case, why not have it operational!
9/11 also reinforced that a weapon system with limited range/explosive power (warning/light damage etc) vs firing missiles, and in visual range, was still very much needed.
It’s a pain to maintain though, has to come out and be sent off to a workshop every couple of months. A lifetime of doing that and the 100s of people in that chain, adds up.
Be interesting to see if Tempest has a gun.
That’s a huge fairy tale about the gun invented by the RAF to get what they wanted. But nice to see it once again.
I’ve never heard that from the RAF, just from being in industry at the time, but whatever prejudice you want I guess.
When I read all about this bullshit and what they are developing and what we are developing; You should all piss off to another galaxy and test your toys to your own annihilation. Leave those who actually care about the only planet we can presently live on to those who don’t want to maim; kill; and destroy all that matters and spend trillions and trillions on research that has absolutely no benefit to humankind except to cause misery.
It was also a Labour government that launched the carrier programme.
You have the Labour Party to thank for the new carriers.
Precisely Graham. The one-eyed approach taken by some posters is not only disingenuous but deliberately provocative, with no other ambition other than to cause offence!
I think it also leans into Tempest being quite a large aircraft and it doesnt preclude short-medium range drone slaves being launched from sea assets to support a long range Tempest strike.
Good point Watcherzero,
We have heard much about swarms and loyal wingmen drones, but not much if anything about dynamic formations. The ability bring different capabilities into a formation at different phases of a mission would be a very useful capability.
If Tempest has inflight refueling and can be based close enough to the action then such dynamic formations could be created using Tempest, F35B and or Naval autonomous vehicles which might not have the range range / endurance as the large land based Tempest.
Cheers CR
You can see the logic, F35B with shorter range stands off from the target controlling deep strike drones. I don’t see a need to commit to a replacement for the F35B, the F35 will get a more efficient variable bipass engine in the next decade and hopefully direct energy weapons meaning the B’s lower payload/range than the A or C is less of an issue especially when teamed with drones.
How can an aircraft with much lower endurance/range control longer endurance/range drones?? Wouldn’t the lower range one have to come back to be refueled before the drone has completed its mission?
Hi Ron5,
It could work depending on the range and security of the comms link and the rules of engagement. As we all know one of the key points of drones if that the manned aircraft stay out of harms way. However, you are right to point out the endurance issue, but if control of the drones can be handed off from one platform to another reliably then this could potentially be managed during the mission planning process. Obviously, it is a constraint but not necessarily a show stopper in every case.
The rules of engagement could in fact be the most difficult issue to get past if you need human in the loop decision making to avoid collateral damage, but in an open warfare situation the option of going full autonomous earlier in the mission is also likely.
Cheers CR
If your not carrying weapons or low weapons load and cruise at a slower speed you lengthen flight time. Endurance is linked to speed and weight. With right mission planning the F35 could stay a loft longer letting the drones travel ahead. Remember drones are also being considered for refuelling.
Yup, agree entirely.
Its all in the mission planning, I’ve just finished reading Vulcan 607 about the attack on Stanley during the Falklands War. Well worth the read and highlights the complexity of multi plane missions…
Cheers CR
Range/endurance is a factor of speed and weight. Lighter F35 cruising could stay aloft for longer.
I have asked before: what problem is the Tempest supposed to solve? We have stealth in F35 and Mach2 strike and air combat in Typhoon. I can think of only 2 reasons to fund this project:
Cost. F35 and Typhoon are expensive to buy and operate. Tempest must be more affordable or no one will buy it.
Range. F35 and Typhoon are relatively short range without air to air refuelling. A longer range stealth aircraft would add to existing capabilities. So a larger platform looks likely.
But, you could ask the same question ever since the Wright Brothers first took flight…..I guess a quick and short answer would be “Progress”.
Yes i was going to say that
Tempest is solving the long range strike and air-supremacy problems. The Eurofighter is indeed a capable aircraft but we are looking to its successor that will be phased in as the existing second tranche airframes wear out and need replacing. The F-35 is stealthy but it doesnt have a great range and pretty low payload capacity particularly in a stealthy internal stores only configuration.
Im expecting Tempest to carry at a minimum the same weapons weight and volume as on the Typhoon but entirely internally.
Theres an opportunity to build an aircraft from the ground up with the communication capacity to operate drone fleets rather than trying to bodge it on to an existing aircraft not designed for it, and the improved performance of two to three decades of technological development on from the Typhoon for example in electrical energy generation from jet engines theres been a quantum leap in performance, massive improvement in active and passive sensor capability and computing power. The Tempest rather than just having a single primary radar is likely to have several smaller ones distributed around the frame along with optical and signals intelligence gathering sensors built into the airframe rather than carried in pods and limited by the data bandwidth between the weapons pylon and the onboard computers.
I hope the RAF will stick to developing Tempest primarily as an air superiority fighter. It will have a secondary ground attack capability but it would be a mistake to try to give it a long range interdiction/strike role too.
The two roles call for different aircraft designs and capabilities. The F-35 is the interdiction/strike aircraft for the next 30 years and will be progressively updated in engine power, range, loyal wingman etc.
Tempest needs to be a larger, more powerful, longer range version of Typhoon, which, as said above, was compromised by partners wanting a smaller multirole aircraft. Basically, more towards an F-15′-F-22 than a Rafale-F-35.
To have any hope of Japanese involvement in the development it would have to be a larger, more capable aircraft, as they want an F-15 replacement and are gearing up to design and build it themselves.
If it is only the UK, Italy and Sweden involved in Tempest, funding the development is going to be very tight, even if it only results in a next-generation, stealthy son of Typhoon.
Wouldn’t it be interesting if long range temporary tanks on F35 were themselves a simple homing drone that disconnected and flew home when payload had transferred. The F35 then proceeded to target area again in Stealth mode …must stop drinking.
While I agree with you about the radar, it is interesting to note that the present long overdue update to the Typhoon radar is being pushed well beyond what will go on to German/Spanish Typhoons specifically because it is part of the development towards the Tempest radar fit. Beyond my pay grade to comprehend how this and the concept of various small panels distributed around the frame can be achieved, if anyone can elaborate on whether/how the present radar work and that ideal destination can be eventually achieved it would be fascinating to read. Or would it need fundamental changes to the complete radar design asking the question how much or what elements could be transferred to that concept from the present work being carried out..
Tempest is to potentially replace Typhoon. Because it will be getting on for 40 years old.
1- Typhoon will be life expired by 2035/40.
2- Nimrod has finally taught us that rebuilding old aircraft is a stupid idea that doesnt work and costs a fortune.
3- Typhoon isnt stealthy. F35’s stealth is 1990s/early 2000s based. Adversaires have and will move on from that.
4- Typhoon was compromised by the partners and too small thus lacks the range desired.
5- Tempest will integrate with new UAVs by design rather than trying to bodge that into 1980/90 or 90/00s avionics.
I agree that increased range would be a big benefit. Germany has ordered new build Typhoons which will serve beyond 2040 and we could do the same- I’m not suggesting trying to patch up older airframes. The US is still producing new F15s and F16s, both older designs than Typhoon.
The big challenge will be making Tempest affordable. The development costs of F22 and F35 have been enormous, way beyond anything U K and partners could fund. Much of this cost has been incurred on software especially sensor and weapons integration. The Tempest project looks to be aiming for even more complexity. This is a high risk project with little recent evidence to suggest BAE will deliver.
Agree with you. The Germans and the US are accepting that costs cannot be justified. Tempest sadly I feel will end up another British pipe dream swallowing billions. We have a history of “balls ups” so why change? Partnerships with Japan and South Korea and even India make more sense. We have some really valuable expertise and operational experience to offer partners, they in turn can offer scale of economy as production runs will invariably be larger. Typhoon has “legs” for decades to come.
“I can think of only 2 reasons to fund this project:”
3rd reason. Fund the fat cat companies into which much of the MoD budget disappears, for benefit of shareholders. Decade from now Tempest cancelled or reduced, MoD cut again.
Feeling cynical tonight, sorry!
We’ve seen it before. I really hope you’re wrong.
So do I. I stand up for the positives and there are high tech assets we have that others don’t that drain the budget but you still wonder with a huge budget we have just where it disappears to and how little we get. Deterrent in core obviously the big elephant there.
Think your honesty is refreshing. After all corruption has
many faces.
You partially answered your own question.
Cost. Time and again at the 2018 launch the RAF and BAES both stressed the need for low cost, helped in part by extensively leveraging existing avionics systems from Typhoon through spiral development. The RAF don’t want to just maintain numbers, they want to increase them. That only happens through tight purchase and operating cost control. Hence the rapid development cycle to reduce development cost. Also not gold plating the solution by, for example, pursuing state of the art expensive radar stealth solutions.
Range. A larger platform, but possibly with saddle tanks from the start (as illustrated in some slides) in order to maximise internal volume for weapons and/or UAS. Customers not requiring the range could then delete the saddle tank option while retaining the weapons capacity, those might include Sweden and ME countries.
Technology. Major advances in radar, beyond e-Captor Mk2, engine technology including organic electrical power generation and increased autonomy and human interfaces to reduce workload/enable drone management. All aspect stealth improvements of radar, thermal and electronic signatures. Software system that is much faster and easier to integrate updates and support new sensors and weapons.
Can it really be achieved though? The Boeing/Saab T7A development programme was quite rapid and the per aircraft cost is by modern standards quite low. Much of the was achieved by using existing technology on what is a far less ambitious design than Tempest. I believe that technically the aim is achievable. I am much less confident about its affordability. If that isn’t achieved, we risk spending £bs on an exquisite demonstrator in a rerun of TSR2.
Well there are no guarantees. However, T7A demonstrated the merits of rapid development, FGAD and Tempest seem to be committed to this rapid development approach. The French-German FCAS seems a bit less aggressive but still relatively rapid by historic standards. So I suspect everyone sees the writing on the wall regarding costs.
While “spiral development” is a bit of a cliche, it is likely that much of what will go into Tempest in terms of sensors, defensive aids, weapons systems and perhaps significant amounts of software will have been developed to continue upgrading Typhoon, helping to de-risk and prove the solutions. My impression is that a lot of R&D has been undertaken well before Tempest was publicly launched in 2018.
I took away from interviews of BAES and the RAF that I saw in 2018 that there will be a strong control on managing goals and willingness to make trade offs. In other words, Tempest initially only needs to be equal or better than what went before in F-35 and Typhoon, but at lower cost; and able to counter whatever opposing forces might set against it. We shouldn’t repeat the mistakes of the F-22 that drove cost so high by delivering far more than was necessary. Another example would be in the handling of the airframe. Do we need the knife fight in phone box capability of a dog fighter, if the proliferation of Mach 4+, 50g+, lock on after launch, over the shoulder targeting capable missiles, already available today, means there’s no advantage to be gained with such high manoeuverability, either in firing or trying to avoid missiles.
Perhaps what is most important is that BAES seems to perceive that if they get this wrong then it might be the end of fast jet design and development in the UK. That could have knock on effects for RR in the fighter jet engine market, forcing them to cease UK development or even forcing them out of the market entirely. The ripples might then spread out, impacting Leonardo UK and MBDA UK.
In short, if the Tempest Team fails to deliver, or future governments reduce numbers and/or kill the program, then we would be likely to see tens of thousands of high paying professional and highly skilled manual jobs go, along with a large drop in aviation industry exports. It seems like commercial and political suicide for the respective parties to me if that happens.
Absolutely agree on the importance of the project and the serious implications if it isn’t a success. That’s what is worrying me.
The involvement of Saab and Aeralis does imply a T7A influenced approach will be adopted. So at most cautious hope.
Cheers
Hi Peter,
I would also suggest two other reasons. The main reason being that by the time Tempest gets into service the Typhoon will be nearing the end of its operational life. Also, I think there is an increasing realisation within political circles that our defences have been rundown to a dangerously low level. Hopefully the recent review will not be the last uplift we will see over the coming years (COVID not withstanding). As such another reason for the project would be an increase in numbers in the coming decades.
Cheers CR
Its interesting that the reply didn’t mention Tempest, they are leaving their options open.
I really can’t see Tempest ever being ordered due to costs involved in such a large project, but you never know.
So is there any possibility of us getting ahead with maritime drones or has that opportunity gone by now?
So why are we developing 2 drones with 2 teams,? Mosquito and vixen? Would it not be far cheaper to develop 1 with Boeing Australia? Are there differences between them?
One land, one naval.
I think it’s a good decision, we cannot afford a fighter that’s all things to all people, look at the F35. More likely to carry through if we’re creating a replacement for the typhoon alone but I’m still betting on cancellation if I’m honest
All the eggs were well and truely put in the F-35 basket for the QE and PoW carriers.There have been veherment supporters of the F-35 posting on here for years, who strongly “dismissed” those who voiced concerns. The mounting evidence is that their naive acceptence of the sales pitches was misplaced.
The UASF said they would never buy a non stealth aircraft, such was their belief in the F-35. Now not only are they buying F-15’s but the US is about to buy an essentially F-16 updated to 4.5 gen. We now have a 6th gen aircraft in the air before the F-35 has even managed to reach full rate production or resolve all its problems. It’s even possible that the UK may have the Tempest close to production before the F-35 is fully fixed. Even then it seems the F-35 will never be able to reach the target cost of $25k / hour.
Who would have thought 10 years ago the the UK may actually fly a home produced fighter every again?
It seems almost certain the UK will never purchase the 138 F-35’s despite the repeated statements to do so. While money is scrapped together to buy and operate the F-35B, other RN vessels are sent to sea without adquate armament The carriers will spend most of the active service flying UAV’s, unless there is a revolutionary development with the EMALS launch/recovery system. It would be a utter waste of effort and money to try and give Tempest a carrier capability.
On the contrary – F35 has been a huge success.
All those who said it was awful, that we’d be better with Super Hornets, that its cost would never come down – now look like the backward looking small minded twerps they always were. When the Spitfire first flew they’d have been demanding the RAF bin it and go unto WW2 with the tried and trusted (but vaguely “improved”) bi-planes.
There are 100s and 100s in service, its “issues” are no different to any complex aircraft (and look at early Typhoon & F22 experience to see the exact same stuff), whilst its cost has dropped and it is shaping up to be a solid performer over the next 3 decades or more.
In contrast a lot of aircraft have major issues (Super Hornet’s one being nearly enough to cancel it on technical grounds), whilst F35s appear large given the scale of the program but it has been safe throughout and the issues relate to more boring stuff like not buying enough spares or tools and poor supporting IT.
The USAF’s problem is that F22 is kind of average but mostly its development seemingly stopped with being built. It has it seems made very little in progress as a next gen aircraft other than vague “digital century series” waffle which given how poor and even dangerous some of the century series were, seems asinine.
Not that I take everything Lockheed say as gospel but they have delivered over 645 F-35s as of earlier this month. That number exceeds Eurofighter deliveries so far and may also exceed Super Hornet deliveries to date. We should be so lucky as to have Tempest “fail” by only selling so many.
https://www.f35.com/content/dam/lockheed-martin/aero/f35/documents/F35FastFacts5_2021.pdf
See reply to Rogbob.
One point, so far it is estimated about $1Trillion has been spent on the F-35 program so far. For the 645 aircraft that works out at $1.55 billion per aircraft. The F-35 was originally conceived as an affordable replacement for F-15,16 +18’s and A-10’s.
That is not accurate. The $1 Trillion to $1.7 Trillion numbers thrown about are estimates for the entire life time costs for the US forces.
So for starters that would be based on the US forces plan of record for 2,456 F-35s of all variants. It would also be over the planned 50-year life, including all the operating costs. It might also be assuming no significant improvement in operating costs, something that Lockheed is under significant pressure to improve.
There are plenty of things to criticise the F-35 program for. Its slow and buggy software development, its flight and support costs, the ALIS system, etc etc. However, that doesn’t take away the fact that the F-35 is the most advanced military aircraft flying today, or flying in significant numbers for the next 20 years, delivering capabilities that are not available from any other platform, until FGAD, Tempest or FCAS become operational. What is also overlooked is how using F-35 in combination with Gen 4/4.5 aircraft like Typhoon significantly enhances overall effectiveness.
If you want a reference source to use to criticise F-35, then the following link explains the numbers –
https://www.pogo.org/analysis/2020/10/selective-arithmetic-to-hide-the-f-35s-true-costs/
I accept the cost so far seems incorrect. The actual spend on the program so far does not appear available from a reliable source. The quote was from a site called Quora.
That said the original program was intended to provide an affordable, low cost fighter. It has blatantly failed to do this.
I refer you to an analysis by POGO. ” Selective Arithmetic to Hide the F-35’s True Costs.” publishished 21-Oct-2020.This group describe themselves as, “The Project On Government Oversight (POGO) is a nonpartisan independent watchdog that investigates and exposes waste, corruption, abuse of power”
The analysis concludes with the summary: ” As the saying goes, a weapon that is too expensive to lose is too expensive to use. If that is the case, then all the time and money spent to develop and purchase the weapon (F-35) has been wasted.”
One point. The US forces magazine, Stripes, reports predicted “life cycle” cost at $1.727 trillion. It attributes $1.266 trillion to operations and support. It put the cost of the 2,456 aircraft planned purchase at $496 billion. That works out at a cost / aircraft of $201 million.
Do you realise you’re quoting the POGO link I provided to you back at me?
As to the estimated cost of $201 million. Well we’re down from your earlier estimate of $1.55 billion per aircraft. If we keep going at this rate they’ll be giving them away with cornflakes.
More seriously, yes, the F-35 has failed to deliver an aircraft at F-16 procurement and operational costs. It doesn’t take away from the fact that F-35 is still the most advanced fighter flying. Would we like that fighter at F-16 prices and operating costs … absolutely, should we keep pushing Lockheed to drive down costs and fix problems … again absolutely, but there is nothing else that can do what F-35 does and won’t be for at least a decade.
Are you referring to this twerp? USAir Force chief of staff General Charles Q. Brown.
The US Airforce magazine ( Feb 21) reported why the USAF is now looking to buy a F-16 replacement. , he admitted, ” The F-35 program has failed to achieve its goals. There is, at this point, little reason to believe it will ever succeed.”
Forbes ( Feb23 21) also reported Brown’s comments in its article entitled: “The U.S. Air Force Just Admitted The F-35 Stealth Fighter Has Failed.” The article examines why the USAF is not just buying F-15’s again but why it is intends to find an F-16 replacement. It summarises as follows, “Brown’s comments are a tacit admission that the F-35 has failed. As conceived in the 1990s, the program was supposed to produce thousands of fighters to displace almost all of the existing tactical warplanes.”Another article in Extreme Tech consider’s Brown’s comments and reviews the F-35 problems, entitled “The US Air Force Quietly Admits the F-35 Is a Failure.”
So just to clarify is General Charles Q Brown one of the twerps you are referring to?
If the name fits then yes.
Or we could say “head of Air Force with desperate drive to fund a new tactical fighter generation has to diss the current one as insufficient for his plans”.
Or even “air force has to blame the plane (which it was deeply embedded with from the outset) rather than spend money on boring things like parts and tools to get the most from it”.
Or “we dont want to look at how we support and operate it because that raises troubling questions about our effiiciency generally, noting LM could run a squadron for about 20% of the people and deliver more sorties”.
As perhaps its all a bit more complex than qouting news articles?
Meanwhile nearly a 1000 F35s are flying and doing missions, and notwithstanding issues (find me a jet that didnt have 10 years of them! Indeed, some never get over them cough Tonka), is and will perform for decades.
From a UK perspective its been a staggering success, successor STOVL ac with LO and sensor fusion above anything we have done, not to mention the industrial work and expertise developed – which underpins Tempest.
Hard to fault it really.
People read too much into USAF head’s comment. He certainly didn’t say F-35 is a failure as some headlines like to characterise it, only that it failed to meet its goals. But claiming he said it was a failure, rather than the more nuanced reality, gets more clicks on websites.
What F-35 “failed at” was achieving F-16 levels of purchase and operating costs. Which is hardly surprising given the complexity and capability of its systems, the maintenance costs for maintaining stealth, along with the requirement for three different aircraft from the same design, to highlight just three factors.
Its also worth pointing out that F-16 has had over 4 decades to optimise and reduce operating costs. Typhoon operating costs were higher and then the TyTAN support deal was developed to reduce them by 30-40 percent. So there is certainly scope for F-35 operating costs to improve.
What the USAF head is signaling with his comment, is that he doesn’t think he needs all his fleet to be fifth or sixth gen aircraft. So if Lockheed doesn’t make significant improvements in the F-35 program costs then he may pursue a fifth gen lite aircraft. Its an early shot across the bows for Lockheed.
I accept the cost so far seems incorrect. The actual spend on the program so far does not appear available from a reliable source. The quote was from a site called Quora.

The MOD has probably added to any confusion by using the name Tempest for both the manned fighter and the overall programme, which includes the smaller unmanned craft.
Smart decision since requiring an F-35B forced so many design compromises on the F-35A/C versions. If there wasn’t a STOVL requirement the F-35 would have been like a single engine, mini version of the F-22.
Idiots, plane (sic) and simple.
Advisers / analysts who are advising that the next generation (6) FAA fast air assets will be solely unmanned should be sacked (and never re-employed).
Given the early concept and design phase of Tempest, it would be relatively simple to add the carrier capabilities into the requirements and design it as such.
This ‘decision’ is very short sighted and consigns the FAA into a ‘choice’ between American or French carrier jets (although the later is not really a choice when you analyse it – for STOVL AND CTOL – capital and intended).
No it wouldnt be simple to add the carrier capabilities.
Look at the F18 vs F16 and F35C vs A to see what the difference is (see also F14 vs F15).
Look at Rafale vs Typhoon, if you know any truth about them.
For starters. Larger control surfaces for low speed approach, much heavier airframe to handle the take off and carapult loads.
All that eating weight and performance so it becomes sluggish vs purely land based.
Pointless for a handful of jets and will probably derail the Franco-German project.
Far more sensible to build something more widely usable, and hop on whatever the US do.
But yes, anyone advocating purely unmanned needs to read up on one Duncan Sandys.
In reply, it is mistake to think that adding the requirements at this stage is not simple, especially in a complex project such as Tempest and also given the likelihood this will be the only (optionally manned) jet aircraft development funded by the UK MoD – The implications been clear in regards to a manned F-35B replacement for the FAA (i.e. having to be a second-string purchaser to whatever the USMC purchase for their large deck LHA/Ds).
I should further articulate just to be clear, my original post did not propose multiple versions of Tempest (aka F-35A-F-35C), I wrote add carrier capabilities, as in, develop a single aircraft type. Apologies for any confusion.
Thanks for bring up the ‘teen’ aircraft. The FA-18 series developed for the USN on carriers has been exported to a number of countries national air forces, including recently by Germany.
The Typhoon is great example of international screw-ups in complex projects, thanks for bringing that up. The UK would be better served – especially in Global Britain speak – to go it alone to develop and produce an aircraft to suit its own requirements (including carrier operations). Do it right, and other (countries) will purchase it (e.g. FA-18).
The Rafale programme is a model for a sovereign defence project. The French did not want to compromise their requirements in a multi-national blackhole, so went alone. Of course, they did make the mistake (just like the F-35 and Typhoon) in deciding to develop multiple aircraft types or iterations (e.g. the F-35 Bk-IV upgrades, Trance 1, 2 etc..) rather than just develop the carrier version only.
Finally, it is easy to focus on a less than desirable design outcome, such as the added strengthening required for the loading during carrier take-off and landing operations, and not mention the positive attributes of a design solution (in the example given the ability to use austere airfields) and larger control surfaces also have benefits in air combat manoeuvres, especially in aerodynamically unstable aircraft.
Ok so I agree it is simpler in a “dont go backwards and redo sense” but it is absolutely not simpler to have requirements for land and sea that are in places conflicting. Having carrier compatibility requirements in would have a negative effect on the Tempest aircraft by requiring it to be able to do things that very few Tempests will ever do. In an already incredibly constrained and challenging design space that makes no sense.
Especially as the UK carrier mode is STOVL and brand new. If anything it’ll be Tempest’s successor generation that replaced F-35B so there isnt really even a requirement.
Plus we have that Tempest is actually FCAS, a family of platforms, so there is no reason why a carrier capable UCAV could not come into FCAS now or in the future.
So the sensible course is to invest in what we have (F35B) and see how things develop both UCAV wise and what the USN/USMC do, noting they have an order of magnitude more resources than us.
Speaking as an aerodynamicist, your belief in the manoeuvring advantages of larger control surfaces is fundamentally wrong by the way. F-35A will reasonably comfortably out maneouvre an F-35C.
Those larger surfaces, outside of the low speed flight envelope they are needed for, are simply wasted weight and drag to be carried around. They offer no advantage as if you tried to use them elsewhere speed wise you’d rip them off / over control the aircraft. The heavier airframe weight also has to be lugged around as does the larger gear. Look at empty weight comparisons of say Typhoon vs FA18 and you’ll see why air combat between them wouldnt even be close (that is assuming the Typhoon was foolish enough not to have won from range!).
FA18 sales, you know surely that combat kit sales are 90% political. The Germany sale is a nearly globally unique “need a platform for US nuclear weapons and they wont agree/demand exorbitant price for anyone else’s plane”. The actual capabilites are kind of moot providing the kit isnt entirely rubbish, even then half the time it still gets bought! Other purchasers were decades ago when nothing else multi-role was around, and it was fairly unique in offering that and reliability compared to Euro aircraft – even then the simple, land optimised F16 has utterly trounced it in sales – the obvious lesson for Tempest there being design for the mass market not the niche one. Something the UK forgets most of the time and has a terrible record of producing great niche things that suck the resources up for little actual return (VC10, BAE 146, Merlin, Tornado ADV, hell even Harrier).
Ref Typhoon, please evidence the claim that going it alone is cheaper – its a idea I’ve heard many times but never seen any evidence for it in terms of numbers. The multi-national love fest is a mess as Ive plenty of experience of – but that is the reality of the modern world and especially when one considers that it took the US some 300plus billion to develp F35, and our resources are circa 1/10th of them so how do we square that circle?
Iterating aircraft types is the exact thing we need to do and is one of the key positive lessons of recent decades, and indeed, back to the jet age, look at Airbus, Boeing etc. The USAF’s entire future fighter strategy is based around it. That thr Tranche1s are going is no different to what the USAF did with F-15/16As and indeed nearly every aircraft type has had initial and then more advanced versions (including the Lightning, Hunter, Harrier and so on), except we dont have their deep pockets to have Reserve units still fly the old ones.
Trying to perfect something and then sticking with that forever on a do or die sense would be insane. Spiral development is a buzz word but its basically common sense, dont try and get to 100% at the start (take the 80% solution) but also dont put in concrete what you’ve done – not least as you’ll need to fix things that you find out are wrong.
Rafale btw was not the French not wanting to compromise requirements – but not wanting to compromise workshare (compare its supersonic agility and supercruise to Typhoon to see where they absolutely did compromise requirements). The exact same problem with Dassault that is now bedevelling the Euro FCAS project.
All the talk of unmanned makes me wonder if they will ever happen for fighter jets. The key issue I see is that politically its going to be hard to have a fully automous weapon. Which means you need a remote pilot like the reaper’s use. The issue with remote pilot is lag on the signal and that can’t be resolved due to physics. As such the manned jet will be able to make decisions faster and therefore in theory be able to shoot first. All things being equal (peer warfare) who ever reacts first wins.
The answer was carefully crafted to avoid saying that Tempest will never, ever perform the maritime combat role.
However this article and the ensuing comments assume that it did. Bit silly really.
If the Tempest and F 35 s could be the last manned jet fighters in service with our armed forces i take it the unmanned drones fighters would cost a lot less and we could have a lot more land based and sea based how ever would that mean that a new carrier would be required for that purpose like what turkey has been talking about a drone carrier and that would be a mother ship for them does any body know the cost of these drone fighters per item etc,
I think this is the best choice. Every indicator is that future manned fighters should be larger than the current generation, and even if our carriers had cats and traps the size / weight limitations would be restrictive. I don’t know how large Tempest will end up but this way it can at least be unhindered by naval requirements.
I’m not a F35-basher, I think F35b is the best (realistic) choice right now for our carriers, but there are clearly limitations with F22 and F35 that the Americans themselves are now coming to terms with when facing up against serious adversaries. The main one is lack of internal weapons capacity and lack of range without external fuel tanks in order to maintain stealth over long-ranged sorties in hostile airspace. Couple that with the vulnerability of airborne refuelling to long range missiles and future power and space requirements for more extensive defensive countermeasures (be that soft, hard, including directed energy), and it all points towards a larger airframe with greater capacity and endurance.
Tempest needs to get this right as an all round air-superiority and strike platform, because aside from drones and loyal wingmen, unlike the Americans we don’t have the capability to develop and maintain multiple high-end manned aircraft programmes. NGAD for the US Navy and Airforce is actually 2 separate programmes with different requirements, and we totally don’t have that luxury.
Build them all
Why did they not include cats and traps in the initial build of the Queen Elizabeth class . If they had,it would have made them available to more aircraft than just F35 .
I don’t see why electro-magnetic cats and traps should be too expensive considering all the research that has gone into rail guns. That technology should be well-developed and applicable.
