Opana Radar Station

These white domes as pictured are the modern version of radar antennas installed on Thanksgiving Day 1941, after the U.S. military had already been active since 1939 in building their Aircraft Warning System. It was part of a larger structure of 6 mobile radar detector sites on O'ahu, where the former location of Schofield Barracks was replaced by the new location at Opana, a location 532 feet above sea level.

On December 7, 1941, the Opana Radar Site was manned by Privates Lockard and Elliot, who detected approaching aircraft at 7:02 am. The men reported their findings to the temporary information center at Fort Shafter, but it was dismissed twice, reasoning that the activity was a flight of U.S. B-17 Flying Fortress bombers. The events were followed by the attack on Pearl Harbor.
