Bellows Air Force Station

Bellows Air Force Station is a United States military reservation in Waimanalo, Hawaii. Established in 1917 as the Waimanalo Military Reservation, it was renamed Bellows Field in 1933. The site became a permanent military post in July 1941 and served as an active airfield during World War II. In 1958, the runways were decommissioned and the facility was redesignated as an Air Force Station. Between the late 1950s and the adoption of military satellite programs, the station operated as a high-frequency radio transmitter facility with links to Clark Air Base and McClellan Air Force Base.

Detachment 2, 18th Mission Support Group, based at Kadena Air Base, operates the station. It serves as a military training area and an Armed Forces Recreation Center. The station hosts the Hawaii Army National Guard 298th Regiment, Multi-Functional Training Unit (MFTU), Regional Training Institute (RTI), including its headquarters and two battalions. Marine Corps Training Area Bellows (MCTAB) occupies 1,049 acres of the reservation and is managed by Marine Corps Base Hawaii.

Infrastructure supports non-live fire training, including amphibious, helicopter, and motorized exercises. Facilities include a military operations in urban terrain (MOUT) training system consisting of 74 modular buildings, a forward operating base mock-up, and a combat vehicle operators' course. The station allows amphibious landings to transition directly into maneuver training areas. Recreational facilities include beachfront cabins, camping areas, and apartments. The reservation also contains the Bellows Japanese Cemetery, which is excluded from military use.
