The Kawasaki Ki-102 (Army Type 4 Assault Aircraft) was a Japanese warplane of World War II. It was a twin-engine, 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. This aircraft's Allied reporting name was "Randy".

Design and history

It entered service in 1944, but saw limited action. The main type (102b) was kept in reserve to protect Japan, although it did see some limited duty in the Okinawa campaign. It 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.


Ki-102 prototypes, 3 built Ki-102a (Type Kō) Externally similar to the 102b, but with turbosuperchargers that enabled the engine to maintain its rating at higher altitudes. 57 mm (2.24 in) cannon was swapped in favor of a 37 mm (1.46 in) cannon, and the 12.7 mm (.50 in) rear gun was deleted, 26 built. Ki-102b (Type Otu) Ground-attack variant similar to prototypes, except with revised tail wheel, 207 built. Ki-102c (Type Hei) Night Fighter version with lengthened fuselage and span. Radar under a Plexiglas dome, oblique-firing 20 mm cannons, and the 20 mm cannons in the belly replaced with 30 mm (1.18 in) cannons completed the package, 2 built. Ki-108 High-altitude fighter prototype with pressurised cabin, two conversions from Ki-102b aircraft using the structural improvements used on the 102c.
