Elizabeth Islands Military Reservation

The Elizabeth Islands Military Reservation was built on land acquired by the US government in 1943. It consisted of an early radar, an observation post, fire control towers, and artillery batteries.[1]

The reservation had two Anti-Motor Torpedo Boat (AMTB) batteries of four 90 mm guns each, AMTB 932 on the northern tip of Cuttyhunk and AMTB 933 on Fox Point, Nashawena. Each battery had an authorized strength of four 90 mm guns, two on fixed mounts and two on towed mounts, plus two towed 37 mm M1 guns or 40 mm Bofors M1 guns. These were mirrored across the channel by a single 90 mm AMTB battery at the Barneys Joy Point Military Reservation.[1]

Both islands were disarmed in 1946.[1]
