This weapon was specifically designed as an antiaircraft weapon
in the 1920s and was a good weapon for its time, with training and
elevation
speeds that were excellent for a hand-driven weapon.
However, it
lacked the
muzzle velocity for the antisurface role, and it was obsolescent
against the
faster aircraft
of
the 1940s. Many were diverted to use as submarine deck guns
for the Balao and Tench
classes.
