Aichi Aircraft Company (Aichi Kōkūki KK) — Aircraft & Engine Profile

Aichi Aircraft Company (愛知航空機株式会社 — Aichi Kōkūki KK)

Aichi Kōkūki KK (愛知航空機株式会社), known in English as the Aichi Aircraft Company, was one of Imperial Japan's principal aircraft and aero-engine manufacturers. Founded in Nagoya, Aichi produced a wide range of naval aircraft — from early biplane floatplanes and flying boats to the legendary Aichi D3A dive bomber and the advanced M6A Seiran submarine-launched floatplane. The company also developed its own aero-engines, including a licensed copy of the Daimler-Benz DB 601A inverted V12.

Engines

Aichi developed and produced a small but significant range of aero-engines, including an original experimental radial and two variants derived from German technology:

  • Aichi AC-1 (1929) — Experimental nine-cylinder radial engine, Aichi's first indigenous powerplant development.
  • Aichi Atsuta (アツタ / 熱田) — Licensed copy of the Daimler-Benz DB 601A inverted V12, used primarily in the Aichi D3A and related naval aircraft. The Atsuta name references the Atsuta Shrine in Nagoya.
  • Aichi Ha-70 — An experimental coupled powerplant consisting of two Atsuta engines joined together, developed for high-performance applications.
