History
The AMTB battery at Great Gull Island consisted of two 90mm guns mounted on 90mm M3 fixed gun mounts and two 90mm guns mounted on 90mm M1A1 mobile gun mounts. Concrete pads for both fixed guns were laid in front of Battery Davis (3). The fixed guns were mounted and then removed when the battery was placed in storage due to reduction in personnel. The battery had a dual mission of defense against fast enemy motor torpedo boats and enemy aircraft. The effective range of the guns was about 8,000 yards. Each weapon required a crew of 15, 9 men in the gun squad and 6 men in the ammunition squad.
