Battery 155 - Port Aransas Emplacement #2 Mound

Originally built as a temporary World War II coastal gun battery with two 155mm M1918 rapid fire guns mounted on M1917 Mobile Carriages emplaced on circular Panama mounts.

The 155mm guns replaced a temporary 105mm howitzer field artillery battery on 11 Apr 1942. The two Panama mounts were placed on mounds that were stabilized with gunite. The mounds raised the gun trunion elevation to 37' 6". Both of the Panama mounts were of the 360 degree variety. Ramps were provided to allow positioning of the guns on the Panama mounts. Five splinter proof magazines were provided along with a 23' by 17' plotting room.

The Temporary Harbor Defense of Aransas Pass was deactivated on 1 Jul 1944 and on 3 Jul 1944 the guns were removed. The troops departed on 4 Jul 1944.
