This weapon was used on Akagi
and the Furutakas
as well as some
escort vessels.
Relatively
few were produced, and the gun suffered from
an inappropriate choice of powder grain, leading to unburned
grains at
the muzzle, which reduced accuracy. The propellant problem was
resolved
late in the war.
A number were used for coastal defense, as shown in the photograph above.
