U.S. Naval Base, Pearl Harbor, Battery Adair, Princeton Place, Pearl City, Honolulu County, HI

Significance: Facility No. 446, Battery Adair, is significant as one of the earliest defensive facilities in Pearl Harbor. It was completed and armed in 1917 by the Army to protect both the Naval installation at Pearl Harbor and the Army's harbor defense batteries at Fort Kamehameha from a rear, land-based attack. It is also significant as a distinctive type of construction, a casemated gun position, comparable only to Battery Boyd, which is also on Ford Island. The design of Battery Adair is related to a specific period of land defense battery construction in the first decades of the twentieth century. This battery is also associated with the events of December 7, 1941, when it was used as a shelter during the Japanese attack. It is a contributing element to the Pearl Harbor National Historic Landmark.
