On 17 March 1944 Rolls-Royce commenced work on the RB40 as the result of a Government request for a turbo-jet of 4200 lb thrust. After discussions with Supermarine, the airframe designers, the engine was scaled down to produce 3400 lb. The resulting Nene was eventually rated at 5000 lb and powered the Hawker Sea Hawk and Supermarine Attacker.
