The 16th Coast Artillery Regiment was a Coast Artillery regiment in the United States Army, along with the 15th Coast Artillery, it manned the Harbor Defenses of Honolulu and other fortified sites on Oahu, Hawaii from 1924 until broken up into battalions in August 1944 as part of an Army-wide reorganization.[1] The regiment manned many gun batteries at locations all over Oahu.[2] Most of the forts where they were assigned were originally built 1899–1910, and had been in caretaker status for more than 30 years. On the morning of 7 December 1941, the soldiers of the 16th Coast Artillery manned their anti-aircraft guns, bringing down six of the attacking Japanese aircraft.
Forts and Batteries manned by the 16th Coast Artillery
Fort Ruger was located in and around Diamond Head.[2][3] The interior of the volcanic cone was accessible through two tunnels large enough for trucks. The administrative buildings were on the north side of the cone. The batteries included mortars placed when the fort was built, dating to 1910. Battery Ruger, like all of the 155mm batteries, were temporary emplacements using four "Panama mounts", a circular track surrounding a center pivot where a 155mm GPF gun was mounted. Battery Granger Adams was a typical pre-World War II coast defense emplacement, with the magazine in a protected bunker and the guns behind parapets in open mounts. It was built 1933–1935, with two 8-inch guns.
Fort DeRussy was located adjacent to Honolulu, on a portion of Waikiki Beach.[2][3] The large caliber guns are mounted to disappearing carriages that use the recoil to lower the gun from the parapet to the loading platform. The allows the reloading crew a work area protected from shells fired by off-shore ships. The Anti Motor Torpedo Boat (ATMB) battery protected the close-in area around the fort from attack by high-speed motor torpedo boats.
In 1918, President Woodrow Wilson designated 322 acres (1.30 km2) of land on Mokapu Peninsula, naming it Kuwaahoe Military Reservation. In 1939, the Navy constructed a small seaplane base there, designated as Naval Air Station Kaneohe Bay. The Naval Air Station's role was expanded to include the administration of the Kaneohe Bay Naval Defense Sea Area. A part of the 16th Coast Artillery moved onto the reservation in 1941. In 1942 the portion of the reservation that was occupied by the Coast Artillery was designated Fort Hase.[2]
Battery North Beach was four 155 mm (6.1 in) rifles on "Panama mounts".
Battery Pyramid Rock was four 155 mm (6.1 in) rifles on "Panama mounts".
