British carriers eye large drones to boost aerial capability
Two British Queen Elizabeth-class aircraft carriers, despite their size, have limitations due to the lack of catapults. This affects the capabilities of the air group, which has been deprived of the support provided by onboard early warning aircraft.
Two British Queen Elizabeth-class aircraft carriers – HMS "Queen Elizabeth" and HMS "Prince of Wales" – are vessels with a displacement of nearly 72,800 metric tonnes, which entered service in 2017 and 2019. Although these are technically very modern ships, design assumptions limit the capabilities of the units built at a cost of nearly £6 billion.
This is due, among other things, to the absence of catapults. Their absence necessitates the launch of onboard aircraft using a bow "ski-jump" – a ramp that propels the accelerated aircraft upwards. This limits the weight, and thus the fuel and armament carried by the launching aircraft, and narrows the choice of potential onboard machines.
As the backbone of the air group of both vessels, the UK chose American F-35Bs, capable of vertical and short take-off, but such capabilities are not present in maritime early warning aircraft (AWACS), such as the E-2D Advanced Hawkeye.
Merlin HM2 helicopters instead of AWACS
Their role was assigned to Merlin HM2 helicopters, which were equipped with the reconnaissance complex (Airborne Surveillance and Control – ASaC) Crowsnest. This includes a single, mechanically controlled head with a radar, lowered under the helicopter's fuselage after take-off.
The theory that these machines would effectively replace maritime AWACS has not been confirmed. The lack of reconnaissance machines resulted, among other things, in the failure of the British aircraft carrier – much newer and larger – in a simulated confrontation with the French aircraft carrier "Charles de Gaulle". The French, with a smaller ship and 4th generation aircraft, managed to gain an advantage thanks to better reconnaissance.
Large drones as AWACS aircraft
Therefore – as reported by the UK Defence Journal – the UK is considering supplementing the air group of both aircraft carriers with AWACS. However, their role would be filled not by manned aircraft, but by large drones, such as the MQ-9B SkyGuardian, offering not only adequate payload but also a significantly longer flight time than helicopters.
According to the UK Defence Journal, tests of this solution are already underway, and successful launches of MQ-9B have been conducted from the deck of HMS "Prince of Wales", being the largest drones ever launched from a Royal Navy ship.
