Bellows Air Force Station, also known as Bellows Field, is a United States military reservation located in Waimanalo, Hawaii. Established in 1917 as the Waimänalo Military Reservation on a former sugarcane plantation, it was renamed Bellows Field in 1933 in honor of Lt. Franklin Barney Bellows. It became a permanent military post in July 1941 and was targeted during the attack on Pearl Harbor on December 7, 1941, resulting in two United States Army Air Forces airmen killed and six injured. A B-17 bomber was forced to land there during the attack. The field was used for recreational gliders in the late 1950s and early 1960s, and also served as an Air Force transmitter-facility site for long-haul high-frequency radio communications until the military satellite program largely replaced HF radio. In 1958, its flying field status was terminated, and it was renamed Bellows Air Force Station, primarily serving as an Armed Forces Recreation Center. It provides beachfront cabins, camping, and condominium-style apartments for active duty, reserve, and retired military personnel. Since 1999, approximately 1,049 acres of Bellows have been acquired by the Marine Corps, becoming Marine Corps Training Area Bellows (MCTAB), part of Marine Corps Base Hawaii. MCTAB is utilized for non-live fire military training, including amphibious, helicopter, and motorized exercises. Recent improvements include a forward operating base mock-up and a modular military operations in urban terrain (MOUT) training system. The Hawaii Army National Guard's 298th Regiment, Multi-Functional Training Unit (MFTU), Regional Training Institute (RTI) also has its headquarters and two battalions located at Bellows Air Force Station. Operations at Bellows AFS are managed by Detachment 2, 18th Force Support Squadron of the 18th Mission Support Group.
