The requirement for the Wyvern was placed in 1944 as Admiralty Specification N 11/44 calling for a high performance long range fighter, it was to use the large and powerful Rolls-Royce Eagle piston engine, with contra-rotating propellers.
The development was protracted and included several accidents, largely due to the complex engine/propeller combination. Production did proceed somewhat prematurely, but the piston engined variant never actually entered service.
