Summary
Early flight tests of the first General Electric turbojet engine, the Type I-A, clearly showed the need for more powerful engines. GE followed with designs generating increased thrust, including the I-16, designated J31 by the military, which first ran in April 1943. About 250 were built, mainly for variants of the Bell P-59 Airacomet.
When the government believed that future tactical needs would require turbojet engines to use the same fuel as reciprocating engines, GE further developed the engine for the U.S. Navy as a 100-octane, gasoline-burning version of the standard J31 engine, which normally ran on kerosene fuel. That version, along with a Wright R-1820 piston engine, powered the Ryan FR-1 Fireball, the Navy's first partially jet-powered aircraft.
