while the new H-2 design became the "Ghost" – de Havilland jet and rocket engines were all named after spectral apparitions. In July 1943, one of the two H-1s then available (actually the spare engine intended as a backup for the one installed in the Vampire prototype) was sent to the United States, where it was selected to become the primary engine of the Lockheed P-80 Shooting Star. This engine was fitted to the prototype P-80, which first flew on 9 January 1944. The engine was later accidentally destroyed in ground testing, and was replaced by the only remaining H-1 from the prototype Vampire. Allis-Chalmers was selected to produce the engine in the US as the J36, but ran into lengthy delays. Instead, the Allison J33, developed by General Electric as the I-40 (their greatly improved version of the J31, itself based on Whittle's W.1), was selected for the production P-80A. Variants H.1/Goblin I Developed about 2,300 lbf (10.2 kN) thrust (nominal thrust for prototype) and 2,700 lbf (12.0 kN) for production models. Goblin II (DGn.2) 3,100 lbf (13.8 kN) Goblin 3 (DGn.3) 3,350 lbf (14.9 kN) Goblin 35 3,500 lbf (15.6 kN) Goblin 4 (DGn.4) 3,750 lbf (16.7 kN) Allis-Chalmers J36 Licence production in the United States by Allis-Chalmers.
