HMS Queen Elizabeth is the largest and most powerful warship ever constructed for the Royal Navy, but what will she carry?
The term now used for the carriers embarked squadrons is ‘Carrier Air Wing’ (CVW), the previously used Tailored Air Group (TAG) has fallen out of official use. The vessels are capable of deploying a variety of aircraft in large numbers, up to a maximum in the upper fifties in surge conditions.
Captain Jerry Kyd, commander of HMS Queen Elizabeth, commented on the initial deployment and the gradual increase in air wing numbers:
“We are constrained by the F-35 buy rate even though that was accelerated in SDSR in 2015, so initial operating capability numbers in 2020 are going to be very modest indeed. We will flesh it out with helicopters, and a lot depends on how many USMC F-35s come on our first deployment in 2021. But by 2023, we are committed to 24 UK jets onboard, and after that it’s too far away to say.”
In addition to the joint force of Royal Air Force and Royal Navy F-35Bs and their pilots, the air wing is expected to be composed of a ‘Maritime Force Protection’ package of nine anti-submarine Merlin HM2 and four or five Merlin for airborne early warning; alternatively a ‘Littoral Manoeuvre’ package could include a mix of RAF Chinooks, Army Apaches, Merlin and Wildcat.
We understand that vessel would still carry at least one F-35 squadron aboard in such circumstances to offer air defence as well as support to the helicopter assault activities. The Crowsnest AEW&C aircraft will come from a number of the embarked Merlins (any of which can be fitted with the sensor package), the number again scaling with requirements.
Recently, the Ministry of Defence confirmed plans for the deployment of American F-35 aircraft alongside British jets aboard HMS Queen Elizabeth. It is understood that the US aircraft will augment British jets on coalition operations.
We discussed claims that the vessel will not have enough jets assigned to her with retired Air Marshal Greg Bagwell who said:
“There is absolutely no need to fix a flexible capability so far in advance – it hems politicians in unnecessarily.”
A source we spoke to, currently flying the jet, explained to us that the vessels will deploy with the number and type of aircraft required for a specific deployments:
“Where F-35B is based is entirely down to the most suitable basing option for the tasks/missions is being sent to do. If that’s a well-founded host nation base, great; if it’s the Carrier, great; if it’s an austere location, fine. Range, logistics and other ‘enablers’ such as AAR and connectivity will determine what’s the best option.”
Around the time the first carrier deploys operationally, the UK will have 42 F-35 aircraft, with 24 being front-line fighters and the remaining 18 will be used for training (at least 5 on the OCU), be in reserve or in maintenance.
Uniquely for a vessel of this size, it will be common to see the jump-jet F-35B appear to land conventionally. Although the F-35B is fully capable of performing vertical landing, in a similar fashion to the way that the Harrier and Sea Harrier operated, this method of operation places limitations on the loads that the aircraft is capable of returning to the ship with.
As a consequence, to avoid the costly disposal at sea of both fuel and munitions, the Royal Navy is developing the Shipborne rolling vertical landing (SRVL) technique. SRVL is a process designed to land jump-jet aircraft that uses both the vertical thrust from the jet engine and lift from the wings, thus maximising the payload an aircraft can return with and stopping the financial waste that comes with dropping expensive weaponry in the sea in order to land vertically.
Another operational advantage of this technique is that it can increase the landing payload capacity of a V/STOL aircraft, which can be restricted when it lands vertically. It can also reduce the level of wear on the lift engines and extend their operational life. Similarly, it can reduce the amount of wear upon the deck surface of a carrier caused by the downward jet exhaust from vertical landings.
The Queen Elizabeth class mark a change from expressing carrier power in terms of number of aircraft carried, to the number of sortie’s that can be generated from the deck. The class are not the largest class of carrier in the world but they are most likely the smallest and least expensive carrier the Royal Navy could build which still have the advantages that large carriers offer.
British F-35B initial operational capability is scheduled will be declared in December 2018 for land and the from the Queen Elizabeth class aircraft carriers in 2020.
