Originally built as a Taft Period concrete coastal gun battery at Ahua Point with two 12" M1895M1 guns mounted on M1917 Barbette carriages. This was a single story battery with the guns located on open concrete pads away from the magazine complex. Shells were moved from the magazines to the gun loading platform by shell carts. No shell or powder hoists were provided or needed. Electrical power was furnished by the emplacement power plant.

World War I (1917-1918)

The U.S. entry into World War I resulted in a widespread removal of large caliber coastal defense gun tubes for service in Europe. Many of the gun and mortar tubes removed were sent to arsenals for modification and mounting on mobile carriages, both wheeled and railroad. Most of the removed gun tubes never made it to Europe and were either remounted or remained at the arsenals until needed elsewhere. The guns of Battery Closson were not affected by the World War I redistribution or the following 1920 disarmament program.

World War II (1941-1945)

Battery Closson was a part of the Harbor Defenses of Pearl Harbor plan throughout World War II. The Battery was casemated in 1942. When the war ended in 1945 the battery was declared surplus. The guns and carriages were processed for salvage in 1948.

Current Status

Battery remains on Hickam Air Force Base across from Mamala Bay Golf Course. No period guns or mounts in place.


Location: Across from Mamala Bay Golf Course, located on Hickam Airfield, Honolulu County, Hawaii
