History
The Aichi B7A torpedo bomber was an attempt by the Japanese Navy to provide a state-of-the-art general purpose carrier-based bomber to replace the Nakajima B6N “Jill” torpedo bomber and the Yokosuka D4Y “Judy” dive bomber with a single type capable of both roles. It was planned to operate these aircraft from the IJN’s largest carriers, the Taiho and the Shinano. Powered by the new Nakajima Homare 1800 hp. radial engine, the first prototype was built and flown in 1942, but development problems, mainly concerning the engine, slowed the aircraft’s path to service introduction. By the time production started in 1945, an earthquake had destroyed the plant, and only a few were actually allocated to units.
