The Ministry of Defence have confirmed that the Queen Elizabeth class carriers might be fitted with catapults ‘in the coming years’ in order to launch certain types of aircraft.

Kevan Jones, MP for North Durham, asked via a written Parliamentary question:

“To ask the Secretary of State for Defence, what assessment his Department has made of the feasibility of fitting a catapult system to Aircraft Carriers.”

Jeremy Quin, Minister of State for the Ministry of Defence, responded:

“Since the Queen Elizabeth Class carriers entered service no such feasibility assessment has been made. In the coming years, the intent is to expand experimentation of Uncrewed Air Systems (UAS) with Royal Navy vessels. This may include a number of projects to consider UAS capabilities for the Queen Elizabeth Class carriers. Including Fixed Wing UAS. The launch and recovery systems for these capabilities may require assessments which could include catapult systems.”

This isn’t entirely new news, however. It’s been known for some time that the Ministry of Defence were looking for information regarding fitting catapults to certain unspecified ships capable of launching aircraft of a certain weight (more about that below). The new news here is the confirmation that it’s for the carriers and that it’s part of efforts to operate large uncrewed aircraft from the decks of the carriers.

Back in March, I reported that the Ministry of Defence was 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 with potential for use with both crewed and un-crewed air vehicles.

The Ministry of Defence also 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. They aren’t, they’re looking to “add mass” to the F-35B fleet by complemening it with uncrewed aircraft like ‘Vixen’. You can read more about Vixen by clicking here or by visiting the link below.

What will the Royal Navy’s new Vixen jets look like?

The drones that come out of project Vixen might be used for a wide range of tasks. You can read more about the aerial surveillance side of things by clicking here and the aerial refuelling potential of the drones by clicking here.

Please note, this isn’t for Tempest.

MoD confirm Tempest jet will not be carrier capable

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”.

The statement is typically vague. The RFI refers to both crewed and uncrewed air vehicles. Whilst most attention is focussed on UCAVs, what crewed aircraft might need cats and traps? 55000 lbs is too low for currently available aircraft at max t/o weight except Gripen. But the upper weight limit implies quite a large aircraft.
My guess is this will come to nothing because costs for the RN will be greater than ordering more F35s.

I hope you’re right mate, just having the ability to launch slow, loitering AEW drones and tankers would be a huge ‘force multiplier’ (apologies for the cliche).

I know there’s been big advances in this area but I just wish they’d have kept it simple and went with C&T’s to start with. I know there are pro’s and con’s but for me the pro’s edge it.

There is space to fit one on the upper deck that is why the front is quite thick.

However could we ever fit it on the ramp too? Would that be too complex? Else it it to the port and starboard of the ramp are the only spaces but that may mean max wing span limits and loss of parking space either side.

I guess the most important thing is how much the conversion will cost. I’m assuming it till be just the one catapult per ship and they will not remove the ramp.
Does anyone know how these requirements compare to the emals requirements for the Ford carriers? could we potential launch a fully laden fighter from one or is it only good for smaller uavs?

Not meeting program requirements doesnt mean it doesnt work. They maintain steam catapults every night to reset any faults and that is well before even 100 catapult launches per catapult.

The F-35B failed to meet spec in a lot of areas. Doesnt mean it isnt working. It means the contractor over promised and under delivered.

If failing to meet requirements still means exceeding the Nimitz class in launches, then I’ll gladly fail requirements

The Ford would have deployed this year but the shock trials were mandated by Congress. Mind you the Nimitz didnt have their shock trials done until 1987, so the Ford is being shock trialed abnormallu early. They doubled their cat and trap numbers in the past year alone.

Compared to the EMALS/AAG combination, we’re not speccing the same: That system has max launch weight of 32,000 kg and arresting weight of 25,000 kg, while ours is 25,000 kg and 21,000 kg respectively. Interestingly, compared to the current gear on a Nimitz (36,000 kg and 23,000 kg), the arresting weight is actually not that far off. I think the real calculation is also to do with the minimum landing speeds and room available for take-off and landings though, so just going by weight is a bit of a simplistic exercise.

As I understand it these are small cats & traps designed to launch / recover small unmanned aircraft NOT the full on ones that launch manned aircraft. The problem is that having a basically STOVL carrier which doubles up with Cats & Traps is going to make the deck layout exceedingly complicated. Any ideas how that works? Maybe a second angled runway to port of the ski jump (expensive). Whatever they do the deck management is going to be extremely difficult.

The obvious placement for the catapult is to run lengthwise along the ship, parallel to the take-off strip and ramp used by the F35Bs. However the clearance between the rightmost edge of the ramp and the leftmost edge of the front island would possibly limit the possible wingspan of the UAVs that could be accommodated.

As you say, we risk having very awkward deck arrangements if this plan goes ahead. I think it’s the worst possible option. We have (rightly in terms of manpower and other costs) chosen a STOVL design. Operating F35b alongside rotary wing craft has been practised and is, relatively, straightforward. The USMC is looking at options to fly AEW missions from their America class carriers. Without cats and traps, they need a STOVL/VTOL aircraft. Front runner seems to be an unmanned tilt rotor.
This would be a much cheaper and less risky solution for AEW and even refuelling.

The loyal wingman UAV is the big problem. If it is anything like the Australian Boeing prototype, it will be a pretty hefty piece of kit, towards the upper weight limit in the RFI. If a reasonably priced tilt rotor could deliver AEW and refuel, we would be looking at the relative costs of-
a) developing an EMALs and a UCAV and retrofitting the carriers
b) buying more F35s.
I think b) is a better choice. Sticking with an all STOVL/VTOL air group gives options to use other platforms if necessary.

What other STOVL/VTOL options? Everything is in theory and undeveloped.

The USMC talks about developing these things all the time but never does it.

The USN developed the CMV-22 and went right ahead with the E-2D and MQ-25 so they arent touching a tiltrotor tanker or AEW anytime soon.

So the real cost is more F-35Bs and more development of brand new aircraft, while having no USN options

We wouldn’t have to dispense with the “angled deck” though. The angled deck perspective on the Nimitz is defined by the paint and the position of the traps. On QEC, without even amending the deck shape/area we might support something approaching the same length and presumably there is space under deck for where the traps are located. For QEC we might also want to design for more clearance of the bow ramp for bolters.

To be clear I’m not suggesting its just a matter of painting diagonal lines.

The decision on adding catapults to the carriers has been made and yet the decision is not decide/fixed in place until it is observed. It’s a case of Schrödinger’s cats (and traps)

The max trap easily exceeds the recovery weight of any CATOBAR aircraft in US service except the Growler.

The max catapult weight, however, is below what fully loaded CATOBAR fighters would weigh – but not necessarily by a lot. An F-35C without ordnance could be launched, or alternatively swap fuel for ordnance – which would still place it at more gas than an F-35B.

Trap weight is relatively close for an E-2D though, with an empty weight of ~19,500kg.

Empty weight is closer to 40.5k lb

And even 19.5kg empty would still mean nearly 4k in gas which is a lot for a turboprop. Thats hours of flying remaining

Seems so incredibly dense and shortsighted to spend all this for a 55k cat launched drone, while coming up 15k shy of the 70k for a full up F-35C (heaviest carrier launched aircraft right now).

FWIW, the F-35C max catapult launch is not 70K. Note that all the brochure matter says it is “70K class” for max takeoff, but thats land takeoff.

The actual numbers are lower. As the USN has said, the Super Hornet has the superior payload capacity so you can do the math for what that means

Who does one send an idea to if they think they have a out the box low budget solution. A Predator sea guardian for instance only needs assistance for the aircraft to takeoff and with 200m runway to play with and most aircraft only need about 80-90knts to take off. It’s been designed to land on carriers already and it couldnt be hard to put a crowsnest on a revolving front facing nose cone and a little design tweek.

If they had thought about developing a carrier variant of the Typhoon it would have been in service already.
I don’t think they are going for another variant of the F35 that again would have been factored in on the initial orders and I don’t think it is to make carriers available to other carrier capable aircraft from other countries . So that just leaves the Vixen drones .

Should have been included in original design as allows different aircraft to be used from the ship’s only a British government would build the two the largest carriers in RN history and hog tie them to one aircraft (the most expensive variant and least capable F35)they can operate!

Right, I have understood the RN needs and the terms of the RFI from the MoD. However there are three issues that should be looked into. 1. What needs to be done to the carriers, eg deck cutting, power requirements etc. 2. If the deck needs to be cut into and power upgrades are required then would it not be better to make privision for a full cat and trap system for a possible later upgrade. 3. To look into the possibility of combining the ski jump with a EMAL system. 4. Would it be better to have a full… Read more »

They wouldnt need the systems for crewed aircraft as most of NATO countries use the F35b , so a EMAL system would probably serve the purpose for the Vixens .

While most NATO countries use the F-35B, all of them combined dont even meet what the totals of what the USN will field to replace the 560 Super Hornets in service. If the QE will serve 50 years, better to be tied to the USN which has already demonstrated unmanned systems on their carriers and has a next gen fighter in the works, than the F-35B whose main customers (USMC and UK) arent even committed to the full program of record

While I have reservations for the RN operating conventional manned fighters, a middle ground of Stovl F35B and a co based heavy (cats and traps) UCAV solution, does seem a very sensible solution for the 2030’s and forward. I don’t think the lack of ski jump would particularly hamper the F35B either, the QE class have very large decks to play with after all. The main issue would be the longer F35B take off run that would impede deck movements somewhat and require some creative deck handling to keep the sortie rate up when needed. It would make sense that… Read more »

It says it’s looking at possibilities for marine development, manned and unmanned. But no where is there any linkage to cats and traps for manned planes.
The words are designed to confuse.
The work is suggested to examine what is available to be produced. If it is available at 2x then we could therefore produce x.

I always come late to these chats as otherwise engaged evenings but a few thoughts and questions. When mooted originally the cost was prohibitive-in the Billions, so why would it be considered now particularly considering the time needed to do such a major fit and work it up would require a long out of service period? The F35B may not have the performance of other conventionally launched jets but still gives the RN a capability way above that of the Harrier and surely more than adequate to task? Also can one catapult an aircraft manned or unmanned up the ski-ramp.… Read more »

So now to launch UAVs they’re looking at an EMCAT and arrestor wires with a MTOW of 25k kilos. Because of course they are. Why not have a 65K STOVL carrier with CATOBAR facilities but only for drones, that’s logical.

During my time with the ACA design team between 2002 and 2012 I made very similar statements on this subject. It would have allowed cross deck operations with the French and US Navies whilst still able to operate STOVL but more importantly support future Maritime Aviation. Sadly, I was too junior to be taken seriously and financial constraint were the given reason for not progressing the line. Personally, I believe political infighting within the military, particularly the RN and RAF, played a large part in investing for this future innovation. I am positive the progression of this activity will benifit… Read more »
