This NICK was one of about 145 Japanese aircraft delivered
to the United States for evaluation after the war. The Ki-45 was used
primarily in the ground attack and anti-shipping roles. The Toryu was
also the only Japanese Army night fighter to see action during the war.
The Ki-45 was popular with flight crews, who used it mainly for attacking ground targets and ships. This Ki-45 Kai Hei night fighter version (one of 477) is the last known surviving "Nick" of the 1,700 built by Kawasaki.
