Ki-102c was a night fighter
version armed with two 30mm Ho-105 cannon
in the fuselage belly and two 20mm Ho-5 cannon
mounted obliquely in the
fuselage. It carried a revolving dish radar
in a plexiglass dome on the top of the fuselage. This version could not
carry bombs. The war ended before it
came into full production.
The Ki-102 was derived from the Ki-96 heavy fighter, a twin-engined aircraft with a pressurized cabin for high altitude that never went into production. The design team, led by Doi Takeo, suggested to the Army that a ground attack version of the Ki-96 should be developed to replace the Ki-45 "Nick". Approval was given in August 1943 and the first prototype flew in March 1944.
The Ki-102 added armor
and fuel tank protection and
heavier armament to the Ki-96, yielding a
capable ground attack aircraft. Its performance and handling were
considered highly satisfactory. Most were held in reserve in
Japan against a possible Allied
invasion, but a few were released for action in Okinawa.
The aircraft was also the intended platform for the Igo-1-B
air-to-surface guided missile, which was being rushed through
development for use against any Allied
invasion of the home islands.
A night-fighter version (Ki-102c) was prototyped
but never saw combat.
