Unlike the 5"/50,
the 5"/40 had genuine antiaircraft
capability and was the standard
heavy antiaircraft
gun in the Japanese Navy. The
chief limitation of the gun itself was its low muzzle velocity, but it
might nevertheless have proven effective but for its poor director,
the Type 94 kosha sochi. This
director relied too heavily on manual inputs and was unable to develop
solutions for fast-moving targets nearly quickly enough.
