The Nakajima Kikka (橘花, "tachibana orange blossom"), initially designated Kōkoku Nigō Heiki (皇国二号兵器, "Imperial Weapon No.

It was developed late in World War II, and the single completed prototype flew only once, in August 1945, before the end of the conflict.

Nakajima designers Kenichi Matsumura and Kazuo Ohno laid out an aircraft that bore just a superficial resemblance to the Me 262.

Subsequently the Ne-10 (TR-10) centrifugal-flow turbojet, and the Ne-12, which added a four-stage axial compressor to the front of the Ne-10 were evaluated, however tests revealed that these did not produce enough power, and the project stalled.

[2] Development of the engine was troubled, as it was based on little more than photographs and a single cut-away drawing of the BMW 003, however, the Ishikawajima Ne-20 was quickly built and by mid-1945, the Kikka project was progressing again.

Other more economical projects designed for kamikaze attacks, such as the simpler Nakajima Ki-115 Tōka (which used obsolete engines), the pulsejet Kawanishi Baika, and the rocket Yokosuka Ohka, were either underway or already in mass production.

Compared to the Me 262, the Kikka airframe was noticeably smaller (with just 4/5ths of the span) and more conventional, with straight wings (lacking the slight sweepback of the Me 262).

At this point, the pilot opted to abort the take off but fighting to brake the aircraft and perform a ground loop only put him in danger of running it into other installations.

[1] However, Ishizawa later stated that a limited survey at the Paul E. Garber facility concluded that this Kikka may not be a strength-tester due to the presence of wiring, hydraulics and controls.

[5] Other follow-on versions proposed included a reconnaissance aircraft and a fighter armed with two 30 mm Type 5 cannons with 50 rounds per gun.
