In 1941 construction started on four fixed concrete emplacements for the mobile guns. These emplacements were called Panama mounts because they were first used in defense of the Panama Canal.

Originally a World War II mobile gun battery with four, 155mm, M1917/M1918 guns mounted on M1917/M1918 mobile carriages. The guns and mobile carriages were initially used without fixed gun pads. Construction of the Panama mounts was completed in mid 1941 but the whole battery was not accepted for service until April 1942, four months after the war started.
Before the war, the battery was use as an "Examination" battery to make sure that ships entering the harbor responded to commands. After the beginning of the war, the battery was used as the primary anti-submarine battery.
Battery 155 Point Loma was deactivated when Battery AMTB - Cabrillo became operational in 1943.
