kma371- While the Navy and the NPS have a joint operation of the USS Arizona Memorial, Pearl Harbor-Hickam is a very active joint air force-navy military base. The Navy has submarines and other ships based at Pearl Harbor, Hickam has F-15 and F-22 fighters on air defense alert plus a lot of military transport traffic. The USS Missouri battleship is also on display just west of the USS Arizona, but is not part of the NPS operation.
When I get back over there I will try to find some more frequencies. Local Honolulu City-County Police and FIre are using systems that can't be monitored with a scanner.
The Coast Guard also is active with a ship station in Honolulu and an air station at Barbers Point, not far from Pearl Harbor. Army aviation is at Wheeler Field, next to Schofield Barracks in the center of the island- a very large base, home of the 25th Infantry Division. The Marines and Naval Air are at Kaneohe on the north shore.
