The two Nakajima-Fokker Ambulance Aircraft were Army medical modifications of production, Nakajima-built and engined, Fokker Super Universals. Both were funded by public subscription.

Design and development

The Japanese army first became interested in the potential of ambulance aircraft during the Manchurian incident of 1931, resulting in the modification of a Kawasaki-built Dornier Merkur passenger aircraft. Its publicly-funded success led to two similar conversions of Nakajima-built Fokker Super Universals, the first in 1932 and the second six years later, again publicly-funded. The cabins, which normally held six passengers, were redesigned by Army Dr Yoshinobu Teraj, a longterm advocate of ambulance aircraft. They could accommodate two stretcher and two seated patients plus a medical attendant or surgeon. Oxygen and intravenous feeding supplies were provided. [1]

Apart from the new cabin the Nakajima built Fokker Super Universals had the same design, structure and dimensions as the U.S.-built originals but differed in their engines, weights and performances. The US version had a 410 hp (310 kW) Pratt & Whitney Wasp [2] but the Nakajima Super Universal replaced this with a 420 hp (310 kW) Nakajima Jupiter early in production, then later a 460 hp (340 kW) Nakajima Kotobuki 2-kai-1. Similarly, the first ambulance had a Jupiter and the second a Kotobuki. Its greater power increased the second aircraft's cruising speed by 27% but its fuel consumption decreased the range by 14%. [1]

Operational history

The individual histories of these two individual ambulance aircraft are not known but air ambulances played a vital role following the Manchurian Incident, when the first was available. [1] The Second Sino-Japanese War broke out in 1937, shortly before the donation of the second.

It was later used in a training role.

Nakajima Ki-6 Japanese transport aircraft

The Nakajima Ki-6 was a licensed-produced version of the Fokker Super Universal transport built by Nakajima Aircraft Company in the 1930s. Initially used as an airliner, the militarized version was used by the Imperial Japanese Army in a variety of roles, ranging from medical evacuation to transport and training aircraft. It was used extensively in combat zones in Manchukuo and in China during the Second Sino-Japanese War.

Fokker Super Universal Type of aircraft

The Fokker Super Universal was an airliner produced in the United States in the late 1920s, an enlarged and improved version of the Fokker Universal, fitted with cantilever wings and an enclosed cockpit. It was subsequently also manufactured under license in Canada, and in Japan as the Nakajima-Fokker Super Universal and for the IJAAF as the Nakajima Ki-6 and later in the puppet state of Manchukuo as the Manshū Super Universal.

Fokker F.XIV Type of aircraft

The Fokker F.XIV was a cargo plane built in the Netherlands in the late 1920s by Fokker. It was a high-wing cantilever monoplane of conventional trimotor layout. The sole example was tested by KLM but never put into service.

The Aichi AB-1 was a result of a 1926 government call for a small, Japanese-built, civil transport biplane able to operate from land or water. It won the contest in both roles but did not reach production as airlines moved from biplanes to monoplanes. Nonetheless, it remained in commercial use well into the 1930s.

The Heinkel He 62 was a reconnaissance seaplane designed in Germany in the early 1930s. It was a conventional, single-bay biplane with unstaggered wings of equal span. The pilot and gunner sat in tandem, open cockpits. A few aircraft were supplied to Japan, where Aichi built a version as the AB-5, and used it as the basis for the AB-6, but no series production took place. The AB-5 used a locally produced Nakajima Kotobuki in place of the Siemens engine fitted to the German-built aircraft.

SAI KZ IV Type of aircraft

The SAI KZ IV was a light twin-engined aircraft first built in Denmark in 1944 for use as an air ambulance.

The Nakajima P-1 was a 1930s Japanese single engine, single seat biplane intended for night mail flights, derived from the Nakajima E4N3 Naval reconnaissance seaplane. Nine were built.
