Naval Support Facility Diego Garcia hosts a joint military airfield on Diego Garcia, a coral atoll in the Chagos Archipelago of the British Indian Ocean Territory. The facility is operated primarily by the United States Navy and supports U.S. and allied military operations across the Indian Ocean region. The airfield features a runway capable of handling large military and strategic aircraft, including B-52 bombers, KC-135 tankers, and maritime patrol aircraft. It has served as a critical staging point for operations in the Persian Gulf, Afghanistan, and broader Indian Ocean theater. Access to Diego Garcia is strictly controlled and limited to authorized military and government personnel. There is no civilian commercial air service, and the island is closed to the general public.
