Nakajima LB-2

The Nakajima LB-2 was a long-range, land-based bomber developed in Japan for the Imperial Japanese Navy, of which only one prototype was built. Kenichi Mitsumara's design was inspired by the Douglas DC-2 that Nakajima was then building under licence: a conventional all-metal low-wing cantilever monoplane with twin engines, main undercarriage units retracting into the engine nacelles and an internal bomb bay. The prototype was completed in March 1936 and considered for production alongside the Mitsubishi G1M, but both lost to the Mitsubishi Ka-15, which was built as the G3M. The prototype was then converted into a six-passenger airliner named Akatsuki-go, delivered in 1937 to Manchukuo National Airways, and it was scrapped at Shenyang in 1941.
