The Ishikawajima Ne-20 (Japanese: 石川島 ネ-20) was Japan's first turbojet engine. It was developed during World War II in parallel with the nation's first military jet, the Nakajima Kikka.

Design and development[edit]

The decision to manufacture this engine came about because of the unsuitability of two earlier powerplants selected for the Kikka, the Tsu-11 and the Ne-12. The Ne-20 was made possible by Imperial Japanese Navy engineer Eichi Iwaya obtaining photographs and a single cut-away drawing of the German BMW 003 engine.

Only a small number of these engines, perhaps fifty, were produced before the end of the war. Two of them were used to power the Kikka on its only flight on August 7, 1945. Only a few of the engines under construction survived. It was also planned to use the engine to power a version of the Ohka kamikaze weapon, but this was not implemented before the end of the war.
