The 124th Fighter Squadron is an operational unit within the United States Air Force (USAF). Established as a fighter squadron during World War II, it has since evolved and adapted to the changing nature of air warfare. Currently, the 124th Fighter Squadron operates the F-15C Eagle, a twin-engine, all-weather tactical fighter aircraft. The unit is part of the Massachusetts Air National Guard stationed at Barnes Air National Guard Base in Westfield, Massachusetts. Throughout its history, the 124th Fighter Squadron has seen service in various conflicts, including the Korean War and the Global War on Terrorism. Its mission includes air defense, close-air support, and the enforcement of No-Fly Zones when called upon by the USAF. The squadron’s motto is “Vigilans,” meaning “watchful” in Latin, reflecting its role as a protective guardian over American interests.
