The De Havilland H-1 Goblin design began in April 1941, and was first tested a year later. It first flew in 1943 in the Gloster Meteor and De Havilland Vampire aircraft. Originally rated at 8,896 N (2,000 lb) thrust, the Goblin II grew to 13,344 N (3,000 lb) thrust, and powered the De Havilland Vampire and 108 Swallow.

A British delegation visited U.S. manufacturers in early-1943, revealing important H-1 details and discussing the possibility of building the engine in the U.S. Subsequently the Navy contracted with Allis-Chalmers for construction of 40 engines.

The first engines were imported for the Navy's Curtiss XF15C and as an alternate for the GE I-40 in the Army Lockheed P-80. The Army used an H-1 engine as the power plant in the prototype XP-80, but it was replaced by the more powerful, 17,792 N (4,000 lb) thrust GE I-40 (J33) shortly before the end of World War II.
