This was the best antiaircraft gun
developed by the Japanese
before the war. It had excellent elevation and reach and
could traverse
quickly. Its rate of fire was good, though not as good as the
U.S. 5”/38
dual-purpose gun. Its directors were also poorer,
and the 3.9”/65
lacked the radar
proximity fuse developed by the
Allies. Only 169 were
produced, and only 100 of these made it
onto ships,
which included the Akizukis,
Taiho,
and Oyodo.
