By 2030, the Royal Navy plan to have moved carrier based ‘Airborne Early Warning’ capability from Merlin helicopters to ‘Vixen’ fixed wing drones.

According to a presentation on the ‘Future Maritime Aviation Force’, the Royal Navy will move airborne early warning capabilities to fixed-wing carrier launched drones called ‘Vixen’.

They say that this will “rejuvenate” the Merlin fleet. Currently, airborne early warning capabilities are delivered by Merlin with ‘CROWSNEST’ pods, you can read more about that at the link below.

Crowsnest early warning helicopter enters service

The presentation states that “by 2030”, the Royal Navy will have:

“Added mass to the Carrier Wing with additional LIGHTNING and medium FWUAS (VIXEN)” and “will have rejuvenated the Merlin fleet, to synchronise with replacement capabilities, transferring PWAS/AEW/Data Node to VIXEN and ASW FIND to medium RWUAS (PROTEUS)”.

The text accompanying the ‘By 2030’ slide is as follows:

“We will have added mass to the Carrier Wing with additional LIGHTNING and medium FWUAS (VIXEN). We will have rejuvenated the Merlin fleet, to synchronise with replacement capabilities, transferring PWAS/AEW/Data Node to VIXEN and ASW FIND to medium RWUAS (PROTEUS). Wildcat will be augmented with additional ASUW/Littoral FIND capability, also by PROTEUS.

Maritime Protector will provide complementary support where teamed with POSEIDON in the North Atlantic. Small UAS capabilities will be spirally developed to encompass EW,UW and target training support.

Successful payload and weapon integration will also be key to the success of FMAF.

In 2030, medium organic UAS will deliver most FIND in the Littoral and Maritime, teamed with crewed air for FIX/STRIKE, and complemented by Maritime Protector. ASW Merlin will regain mass with the transfer of AEW capability to an alternate platform. Together with enhanced FW in the Carrier Air Wing, Maritime Aviation will be reconstituted to match evolving peer threats.”

Discussing ‘Project Vixen’, respected defence journalist Harry Lye wrote:

“Under Project Vixen, the Royal Navy is exploring how fixed-wing UAS could be used for missions including surveillance, air-to-air refuelling, electronic warfare and strike.”

You can read more about Vixen from Harry here.

How will the drones be launched?

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.

While the Request for Information looks to assess the “availability of electromagnetic catapult and arrestor wire systems to launch aircraft” from a ship, words associated with the previous effort to explore converting the vessels to ‘CATOBAR’ in order to launch carrier variant F-35Cs, it shouldn’t be taken as indication that the Royal Navy are abandoning the short take off and vertical landing F-35Bs and returning to catapult launched fighters. On the contrary, they’re looking to augment the F-35Bs.

In fact, the upper and lower weight limits of the catapult and recovery system outlined aren’t enough to launch or recover any variant of the F-35 in normal conditions.

The launch and recovery options mentioned would be utilised for larger uncrewed aircraft as the armed forces begin to rely on them more and more in place of crewed platforms.

Anyway, on to the Request for Information itself.

“Potential supplier and interested parties are invited to provide information in relation to potential solutions which are sufficiently technically mature to be fitted to a suitable ship from 2023.”

According to the Request for Information, the Ministry of Defence have set out the following requirements.

“Potential arrestor solutions ideally should offer:
a. Max trap 47000lbs / 21318Kg
b. Min trap 11000lbs / 5000Kg
c. Energy damping method
d. Potential for energy reclamation

Potential catapult solutions ideally should offer:
a. Max launch weight 55000lbs / 24949Kg
b. Electrical power input required against launch cycle time.”

According to the Ministry of Defence, the intended outcomes of the Request for Information are as follows:

“a. Develop further MoD understanding of the different technologies and capabilities available in the market, both current and emerging.
b. Alignment of potential future MoD requirements with industry standards and processes for procurement of maritime un-crewed and autonomous capabilities; and,
c. Enable the Authority to develop a procurement strategy that will deliver best value for money for Defence.”

The Royal Navy say that the DEVELOP Directorate leads the development of the Royal Navy’s future warfighting capability and “acts as the platform for the through-life capability for all maritime capabilities in order to achieve the optimum mix of present and future warfighting technologies for a modern, global and ready Royal Navy”.

The Royal Navy is driving hard to introduce a range of un-crewed air vehicles and to “give wider options for the use of different air vehicles types within the Fleet”.

Before jumping the gun on this news, a bit of perspective is important. Well respected naval analyst Gabriele Molinellli had the following words of caution to say.

This is a no brainer, however until an elegant solution arrives it would seem that a plausible platform would be the V247.

While Bell are still developing the V247, the USMC MUX project for which it was envisaged has been broken down into smaller subsets. Doubt that the RN has the finances to complete V247 without the USMC backing.

The USMC realised a single drone to do everything wasn’t feasible, hopefully the RN will collaborate with the USMC rather than repeating the same evaluation process. For AEW the V247 would be an excellent choice given it’s not vulnerable to a cat/trap failure.
A fixed wing drone would be better suited for loyal wingman and refuelling roles.

In this circumstance I would have to disagree. The loyal wingman aircraft will need to be more comparable to the F35, in terms of speed, endurance and “stealth”. If is to fly in concert with a F35 there’s little point in having a non stealthy UAV that will stick out like a sore thumb, giving away the F35’s location.

Not so much bigger as higher, therefore further. Once you know something’s out there, maybe you can get a good view of the environment using a combination of F-35s and Crowsnest, but having F-35s flying picket all the time would be very expensive in airframe-hours.

The Armed Services review have already stated that Crowsnest is an interim solution until appropriate drones are in service. Why debate the obvious. Drones are the future for “surveillance” and “dumb” activities like AEW & refuelling. Can we move on?

But I read somewhere (here?) that at height and distance the Samson radar is fine and crowsnest complements for shorter range and lower heights…

I also read somewhere on here that in the more distant future, drones operating at sub orbital heights will give enormous coverage.

This does question how these radars are managed remotely. But I guess this is the first thing they think of. I guess these drones don’t have a ‘bag’ but a ‘plate’ (?)

There is a limit of how high drones can fly.
At 100000ft or 30000m there is little air, you are effectively in space.
Less then 1/10th of sea level pressure at 60000ft
Jet engines don’t work above 90000ft.

The Samson radar range, is still limited by the Earth’s curvature at the horizontal direction.

For air not a lot due to distance and RCS size of the target, though its being considered for the new generation of extremely low orbit satellites.

For anti-surface operations however radar satellites do already provide detection and tracking of ships and submarines.

Its all about where the horizon is. Sampson is 10s of meters above the surface and has a fairly short horizon. RW will fly up to around 10k feet (~3000m) and some distance ahead of the ship. This height and offset significantly increases the distance to the horizon filling in the sampson gap below its horizon. It is a good solution. However, a fixed wing solution would probably operate 2-3x higher (and be faster so it can get further away from the t45) giving an even bigger distance to the effective horizon.

Jamming is not really a problem for point-to-point line-of-site comms. The RF power required to jam P2P pencil beams from a distance is vast. The issue is once you are in line of site with a modern radar that can then blast RF into the receiver saturating the receiver and filling the digitiser. Or the opposition have UAV doing the same however this would be a priority target for area/point defence weapons that we have plenty of. The issue is do you do the data reduction in the UAV or are you transmitting raw. Data reduction requires processing and therefore… Read more »

Raw transmitted data in this situation would be best, as it would mean more resources (electrical power) can be used for the radar’s transmitter-receiver modules thus better power output and receiver sensitivity. It would also mean there is less space designated and required for cooling or housing the signal processing itself. Therefore the UAV would be lugging around less weight, so could potentially have more endurance and fly higher. There is also the case where FFT, can deliberately filter out very small signal returns due to the way it averages out a series of reflections. Having the ability to read… Read more »

Hi Ron, The current Link 16 and 22 even when quad stacked do not have the bandwidth capacity for transmitting raw radar data. The F35’s multifunction advanced data link (MADL), however does. The AN/APG-81 is supposed to be an X band radar operating between 8 and 12 GHz. However, it is rumoured that it can also operate beyond this band in the C and Ku bands. This would give it a very wide communications bandwidth. This type of bandwidth is what’s needed for the AEW drone I would suggest.

The Kratos XQ-58 Valkyrie which is probably of a similar size and design to Vixen is developed from their target drones and shares their JATO method of launch. While it’s probably more expensive per launch cycle, the upfront costs and structural impact on the ship are far lower.

Funded properly and managed correctly, we are able to now envisage a combat system and get it into the air at speeds not seen since WW2.

The 20 plus years from drawing board to squadron service crippled previous generations, with creeping systems obsolescence (requiring expensive upgrades soon after entering service) and successive governments changing requirements and moving goals…

There was a lot of talk and actually some work done on creating an improvised aircraft carrier out of BP oil tanker so that some kind of modified Tornado could participate.

The whole thing was stopped when the capabilities of the Harrier and the timescales involved were realised. The Tornado, as was then immature, wasn’t really any better than the Harrier.

There was also the issue of zero hangar facilities and non navalised planes.

I suspect it lodged in Max Hastings brain.

The Tornado whole undercarriage would of needed heavy modifying for the Traps!
The same issue with a marinize Typhoon and Gripen. And a fuselage redesign, as well with the Typhoon!

The UK did have former RN Phantoms at the time of FW, but handed over to the RAF. They would of needed a CAT to launch from a deck.

Steam catapults have been around for a hundred years or so….and still are the mainstay of carrier launches. We build some very large capacity electric boilers for industrial use! If the QE’s have enough electrical capacity to run emals, then they could have supported steam boilers!

Fully appreciate that but the design study at the time was not for steam, they would never have fitted an ancient technology to the carriers (despite the fact it works reliably).

Personally I have no idea how much space the steam boilers and all the pipe work would take but im sure it would be quite a bit and they simply never got designed from the offset for it.

The only option was emals which if we had fitted would be a total disaster right now.

Herodotus

Reply to  James

So ancient that it is in use in all modern aircraft carriers? Just because steam generation has a long pedigree doesn’t make it ancient technology. So, the QE’s were designed for a new aircraft that had not flown….in order to cover the eventuality of it not working, an unproven and yet unbuilt launch system was to be the back-up! Can you not see the problem here? These are big ships, I’m sure that space for some steam boilers could be found…even if it meant dispensing with the jacuzzies, gymnasiums and the junior rates ensuites!

As I said despite the fact that steam works and is present in most ‘current’ aircraft carriers they simply did not get designed to incorporate it. The ships would need a complete internal redesign to fit it. You made the point they should have just been built from the start with cats and traps and the only option that was studied was emals, it was both horrendously expensive and doesnt work so that wasnt an option hence my response.

You have missed my point! The ship was designed around two unproven technologies The concept of the F35 was not proven by the Harrier….lift fans and computer controlled dynamics are not the same as total vectored thrust…they are vastly different technologies! If the carriers had been designed to incorporate a proven launch system rather than a projected one, we would now have carriers that could fly a range of fixed wing aircraft and drones.

Yes ‘if’ it was designed to use steam then fair play but this was never considered and would have created shortcomings in other areas of the carrier with the space and plumbing needed. F35 may not have been proven however it was never going to fail, too many parties involved from companies to countries. Emals is just a US design currently and im sure they will crack it in time but it simply was not ready for the time we designed the carriers.

I suppose the advantages of a large platform like the QE class, mean serious modification is considerably easier and was always going to happen at some point.

The sky jump was only ever supposed to be for the first 25 years of a projected 50 year design life. Fast moving events have somewhat overtaken this philosophy!

Assuming things pan out, it ‘might’ just finally shut up the Carrier deniers!

Herodotus

Modification, yes but probably not steam catapults though. It depends if the US is going to persist with the development of full-scale emals for its carriers, I guess it has to. If they are successful the probability is that it will be too expensive for us…. thereby limiting the RN to one fixed wing manned aircraft and light weight drones. Life could have been so much simpler!

Could this be the answer?

“EMKIT+ would use a longer launch track (94m) to enable launch weights of up to 10,000kg’s to be accommodated.
For reference, Predator B or Reaper has a maximum launch weight of 4,763kg.”

A Gripen with only a small single jet engine, without vectored thrust, would very much struggle to take off the deck, without a CAT.

The F-35B could still take-off without a lifefan, if it just used the swirl nozzle jet engine to provide vectored thrust to take-off, with ski-jump But with a much reduced take-off weight.

If they ever decide to move forward with Sea Gripen I guess this might be a consideration for the future? Given the advantages it has to offer I’ve never understood why we didn’t move forwards with it for Typhoon. Available since 2010 “Prior to Saab’s selection of the F414G, the Eurojet EJ200 had also been under consideration for the Gripen; proposed implementations included the use of thrust vectoring.” Gripen M: proposed carrier-based version based on the Gripen NG.

I think assisted launch and recovery could reopen doors that might have remained closed.

Saab would be in a prime position to offer friendly nations like India an aircraft/ UCAV that could fly from the decks our carriers.

Saab will be working alongside us with Tempest so let’s see what if anything comes of it.

That is not correct. The “adaptable ” CVF design used steam catapults as its design assumption.

However the 2010 decision to look at cats again, only considered EMALS in their financial estimates. No mention was ever made of the cost of fitting steam. Which is very odd.

Herodotus

Reply to  Ron5

Which begs the question as to whether they were actually built to to be able to fit steam catapults. Probably not as the design was clearly modified…..hence my argument about two unproven technologies. I understand that the possible provision of emals was compromised by design alterations at a later date!

When the design didn’t include provisions for EMALS, how could that design be compromised by design alterations? You can’t compromise something you didn’t have.

There’s not been anything released that would indicate whether steam cats could have been economically fitted or not. Which leads to the conclusion that those folks that controlled the estimating, were STOVL enthusiasts.

I cannot see the sense in fitting Cats and Traps if they cannot launch the full range of aircraft so the carriers can operate other nations aircraft when necessary.
Also looking into the future , our carriers will outlive the F35 and by giving the Carrier Cat and Trap capability it will not constrain the eventual F35 replacement, dare I say it a navalised Tempest!!

Hello Mike, The Specs of the proposed system will exclude most other conventional Aircraft options due to max weights and at a wild guess, the Tempest too. This system is for UAV’s only as far as I can see from what has actually been published….. Personally I’m still not convinced that this system will be for our Carrier/Carriers, a big question is forming in my mind due to the complete lack of reference to said Carriers.

Considering the first study to retrofit CATOBAR was deemed too costly at £1.5B, I seriously doubt EMALS will be feasible since it will likely be more expensive. That said maybe second hand CATOBAR from retiring Nimitz could make their price more attactive than first study?
An off the shelf tilt rotor design seems a more practical solution. Although to fly above 10,000ft and longer, guys on board will need warm parkas and oxygen masks. (The V22 has a square cross section, so no cabin pressurisation.)

The USN ucav programme started in 2007 and by 2014 costs had risen to @$900m. Their carriers already had cats and traps. For the UK to deliver a similar capability by 2030 on vessels that would need to be retro fitted with an EMALS system seems unrealistic.
A rotary uav looks more achievable in the time frame.

Clearly from the slide the RN want to limit land based air to the the overland role in order to justify their aspirations. In reality the land based ISR could provide an umbrella of AAR support and early warning/intelligence over many of their operational areas especially if the ISR assets had AAR available.
