The Nakajima-Fokker Ki-6 Type 95-2 Crew Trainer was based on the Fokker Super Universal and was designed to train the crews of multi-place bomber aircraft.
The Super Universal was a high wing monoplane, with an uncowled radial engine. It had a welded steel tube fuselage with a fabric covering and wooden wings with a mix of plywood and fabric covering. Six had been imported to Japan in the late 1920s, and Nakajima had then gained a licence to produce the civil aircraft. Production began in September 1930 and continued at Nakajima until October 1936 when it moved to Manchuria.
The Japanese Army modified the Super Universal to act as a crew trainer. In this configuration it carried two crew and four students. The student positions were for navigation, radio communications, aerial photography and gunnery, and an open flexible gun position was added behind the wing.
The modified Super Universal was accepted for Army service as the Army Type 95-2 Trainer (Ki-6). One was produced in March 1934 and another nineteen between December 1935 and November 1936.
The Ki-6 was one of three new Army trainers introduced in 1935, alongside two Tachikawa aircraft, the Type 95-1 Intermediate Trainer and the Type 95-3 Primary Trainer.
The Ki-6 remained in use as the Army's crew trainer until the introduction of the purpose-designed Tachikawa Ki-54 in 1941.
The Army also purchased two civil Super Universals, using one as a transport and one as an air ambulance with a crew of two and a medical attendant and room for two stretcher cases and two seated patients.
