The Ho-203 cannon may also possibly have been known as the Type 3 37mm Machine Cannon. It seems to have been installed only on
the Ki-45-KAIb "Nick", where it proved reasonably effective against large bombers.
The gun was derived from the Year 11 Type
direct-fire infantry gun. It used a long recoil artillery-style falling
block action and was fed from a 25-round
magazine in flexible mountings or a 15-round "birdcage" endless belt in
fixed
mountings. The flexible version seems to have never seen combat. The
rate of fire could be adjusted by changing the recoil buffer fluid, but
120 rounds per minute was typical.
