In the end of 1942 the U.S. Navy drew up a specification for a new fighter-bomber with a composite powerplant, which would use one of the new turbojets then being developed, as well as a more conventional radial engine with propeller. The idea was that the piston engine would be used for landing operations, long-range cruising, extra speed to supplement the turbojet, and as an insurance policy against the possible failure of the jet engine. Ryan provided the best proposal, and was awarded the contract, with the first prototype being flown in June 1944. The Fireball was the first U.S. Navy production aircraft to have a flush riveted exterior and metal-covered control surfaces. With contracts calling for 1,300 Fireballs, the FR-1s began to equip the Navy in March 1945; however, VJ-Day cancellations left only 66 examples produced. None of these saw operational use during the war, but Fireballs were used for carrier trials after the war until being withdrawn in late 1947.
