The Aichi B7A Ryūsei ("Shooting Star") was a carrier-based torpedo and dive bomber operated by the Imperial Japanese Navy during World War II. It's Allied reporting name was Grace.
The Ryusei entered production late in the war, in May 1944, and only a small number were built. The only two aircraft carriers large enough to operate the Ryusei, Taihou and Shinano, were sunk before they could embark any of the aircraft. Afterward it was operated from land bases.
