The Mt. Kaala facility is located atop Mt. Kaala (4,025 ft.) which is run by the Hawaii Air National Guard and the FAA.

Access to Mt. Kaala is restricted and accessible via a military road. I did make a trip up there with my father-in-law in the early 1960`s, as he was then Chief of the Electronics Maintenance for the Hawaii Region of FAA at the time. The Radar site was off-limits and I did not take any photographs. The ACW site at Kokee on the island of Kauai is also operated by the Hawaii Air National Guard.

Prior to moving to MT. Kaala, the ACW site operated by the Hawaii Air National Guard was located atop Koko Crater in East Honolulu and entry to the Operations Area was gained via tramway which ran up the face of the extinct crater.
