90 MM AMTB - Typical
Configuration.
There were a total of 12 of
these weapons guarding the
Delaware Bay entrance (8 at
Fort Miles and 4 at Cape
May). The 90MM guns
were installed at Fort Miles
to replace the antiquated
and often un-reliable 3"
M1903 guns.

The Anti-Motor-Torpedo-Boat
(AMTB) 90mm gun M1 on mount
M3 was developed in 1941 to
provide a weapon that was
effective against fast
torpedo boats, aircraft, and
land targets. It could be
controlled manually or
automatically through a
remote control system. A
protective shield was
installed around the gun and
allowed crew access and gun
loading through the rear.
Two batteries of four
weapons each were installed
at Fort Miles on the
Delaware side (Battery 5A &
Battery 5B), and one battery
of four weapons was
installed in Cape May, New
Jersey (Battery 7).
