Battery Henry Adair (1916-1919) - Battery Henry Adair was a reinforced concrete, World War I 6 inch coastal gun battery on Ford Island, Honolulu County, Hawaii.

Deactivated in 1919.
World War I (1917-1918)
Part of the Harbor Defense of Pearl Harbor.
Originally built as a World War I concrete casemated coastal gun battery with two 6" Armstrong M1898 guns mounted on M1898 Armstrong Barbette carriages. This was a single story battery with the guns located on the same level as the magazines. Shells were moved from the magazine level to the gun loading platform by cart and by hand. No shell or powder hoists were needed or provided.
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 6" guns of Battery Henry Adair remained in place until they were directed to be scrapped on 22 Jul 1919 along with most of the inventory of 6" Armstrong carriages and guns. Gun & Carriage cards indicate that the carriages were recorded as scrapped on 6 Sep 1921 and the guns were salvaged on the same date but later entries indicate that the guns were both retained on 23 Dec 1922 as "ornaments", location unspecified.
Battery Henry Adair was over built by the construction of Quarters "K" on Ford Island in 1936. Quarters "K" became the commander's quarters and was first occupied in 1937. The lower level of magazine rooms remained intact as did at least one gun emplacements. No period guns or mounts in place.
