The Opana Radar site is situated on a knoll overlooking the Pacific Ocean, located 532 feet above sea level. It is the highest point in the Opana ahupuaa and provides an unobstructed view out to sea. Today a modern telecommunications station operated by the Navy occupies the top of the Opana Hill. The area is fenced and a roadway leads up from Kamehameha Highway to the site. This site is where radar was utilized for the first time in a combat situation. At this location on December 7, 1941, the Japanese squadron of airplanes was detected on radar prior to their attack upon Pearl Harbor.
