Fort Ruger was located in and around Diamond Head. 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 created, dating to 1910. The eight inch battery was built six years prior to World War II. 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 cannon was mounted. Battery Granger Adams was a typical coast defense emplacement, with the structure buried to provide protection below a parapet.

Fort DeRussy was located adjacent to Honolulu, on a portion of Waikiki Beach. 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.

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.

The shield is essentially Hawaiian. The crossed spears are taken from Hawaiian history, they were formerly placed at the King’s tent, and are shown conventionally in the Hawaiian arms by a saltire cross placed on an inescutcheon. The motto, probably the best known Hawaiian word, is used extensively as a sign against trespassers.
The batteries at Diamond Head constitute the principal element of these defenses.
