Aichi B7A Ryusei

Introduced in early 1944, the Aichi B7A Ryusei was a WWII dive-bomber used by the Imperial Japanese Navy. Although it had been designed as carrier-based aircraft, it could only operate from Taiho aircraft carrier, which was large enough to scramble this big and heavy dive-bomber. However, Taiho was sunk during the Battle of the Philippine Sea, in June 1944. As a result, the B7A would operate only from land bases until the end of the war.

The Ryusei was a two-seat, single-engine aircraft, fitted with inverted gull wing, which could be folded for carrier storage. It had an all-metal fuselage and retractable landing gear. It could carry one 800-kg torpedo or a bombload of 800 kg. As defensive armament, the B7A had two 20mm Type-99 cannons, fitted in wings, and one 7.93mm Type-1 machine gun. Aichi Kokuki manufactured a total of 230 dive-bombers in three versions: B7A, B7A1, and B7A2.
