Although it has been stated that the parasol-winged Nakajima Army Type 91-1 fighter of the early 1930s drew upon the Nieuport-Delage sesquiplane designs, its licence-built 520 h.p. Nakajima Jupiter VII air-cooled radial engine gave it bluffer lines than the inline-engined French aircraft. Popular with its pilots, it was the first indigenous Japanese Army fighter to be built in quantity, 420 Type 91-1s being built from 1931 onwards.

Kawasaki’s Army Type 93 (Ki-3) light bomber was first flown in 1933 and went into production in January 1934. Powered by a 755-800 h.p. Kawasaki-BMW IX 12-cylinder vee inline watercooled engine, it had a distinctive undernose radiator with controllable shutters, seen closed here. Unfortunately it was beset by engine problems which led to termination of production in March 1935, and had a short Service life. The Type 93 could carry a 1,102lb bombload, and had a defensive armament of one fixed forward-firing 7-7mm machine-gun plus one or two more on the rear cockpit ring.

The Nakajima Navy Type 90 (A2N1) single-seat shipboard fighter, designed by Jingo Kurihara, incorporated many features of the Boeing F4B naval fighter in its design, and was also influenced by Britain’s Bristol Bulldog. First flown in 1931, it was built in several variants, a total of about 100 being produced. This is an A2N1-3. The engine was a 460-580 h.p. Nakajima Kotobuki 2 nine-cylinder aircooled radial, and armament comprised a pair of fixed forward-firing 7-7mm machine-guns.

The two-seat Nakajima Navy Type 90-2-3 (E4N3) was the landplane version of the Type 90-2-2 single-float seaplane, designed for shipboard reconnaissance. A modified licence-built variant of the Vought O2U Corsair, it remained in production from 1931 to 1936. The Nakajima Kotobuki 2-kai-1 radial engine gave it a top speed of 144 m.p.h.
