Kawasaki Ki-102

The Kawasaki Ki-102 was a Japanese warplane of World War II. It was a twin-engined, two-seat, long-range heavy fighter developed to replace the Ki-45 Toryu. Three versions were planned: the Ki-102a day fighter, Ki-102b ground attack and Ki-102c night fighter. The Allied reporting name for the Ki-102 was Randy.

It entered service in 1944, but saw limited action. The main type (the Ki-102b ground attack variant) was kept in reserve to protect Japan, although it did see some limited duty in the Okinawa campaign. The Ki-102 was kept out of front line service because it was hoped that it would be the carrier of the Igo-1-B air-to-ground guided missile when the Allied invasion of Japan occurred.
