Fort Kamehameha was a United States Army military base that was the site of several coastal artillery batteries to defend Pearl Harbor starting in 1907 in Honolulu, Hawaii.

Download coordinates as: Secretary of War William Howard Taft under President Theodore Roosevelt headed a group to review coastal defenses, in light of "possessions" such as Hawaii and the Philippines, based on the findings of the Board of Fortifications.

From east to west the sites built in the first phase were:[4] Battery Selfridge was constructed from November 1907 to 1913 with two 12-inch M1895 guns on disappearing carriages, with a range of about 30,000 yards (27 km).

Battery Jackson was constructed in 1913 was equipped with two 6-inch (152 mm) guns on disappearing carriages, with a range of about 15,000 yards (14 km).

[8] Battery Hasbrouck (sometimes misspelled as "Hasebrock") was constructed from July 1909 to 1914 and was equipped with eight 12-inch coast defense mortars, with a range of about 15,000 yards (14 km).

It was directly east of the entrance to Pearl Harbor, designed to protect its mine field, at coordinates 21°19′30″N 157°57′40″W / 21.32500°N 157.96111°W / 21.32500; -157.96111 (Battery Hasebrouck), covering 2.6 acres (11,000 m2).

A few years later an airfield called Luke Field was built on Ford Island, and the site is now owned by the Navy.

In 1920, two 12-inch (305 mm) M1895 guns on a new style M1917 barbette carriage that could traverse a full 360 degrees were installed and named after Civil War General Henry W.

A Japanese Mitsubishi A6M2 model 21 "Zero" was strafing US military personnel when the pilot failed to pull up in time and bounced off the ground, severely damaging the propeller.

At the end of World War II, the coastal batteries had become obsolete, and most of the military installations at the Fort were subsequently demolished.
