彗星 (航空機)
Wikipedia definition
1. Yokosuka D4YThe Yokosuka D4Y Suisei Navy Carrier Dive bomber was operated by the Imperial Japanese Navy. Its Allied reporting name was "Judy". The D4Y was one of the fastest dive-bombers of the war, and only the delays in its development hindered its service, while its predecessor, the slower fixed-gear Aichi D3A remained in service much longer than intended.
