The 439th Airlift Wing
The 439th Airlift Wing is the premier unit-equipped Reserve team hosting joint partners; we are leaders in providing global reach to achieve national objectives.
The 439th Airlift Wing is capable of providing worldwide air movement of troops, supplies, equipment and medical patients. Strategically postured on almost 2,500 acres in western Massachusetts, Westover is the nation’s largest Air Force Reserve base. It is the closest fully operational military base to Europe, providing world-class support to military aircraft and people going to and returning from missions overseas. Support units provide communications, engineering, logistical, medical and security requirements. The peacetime mission includes recruiting, training and supervision of personnel to ensure mission readiness. The wing is also responsible for the management of aircraft maintenance and all assigned Air Force combat support real property, equipment and supplies.
The 439th AW maintains and flies one of the world’s largest transport aircraft, the Lockheed C-5 Galaxy. The C-5 first arrived at Westover in October 1987. C-5s are the largest aircraft in the Air Force and specialize in missions involving outsized and oversized cargo that no other aircraft can carry. The C-5s are capable of carrying 270,000 pounds of cargo. The C-5 cargo compartment can hold six Greyhound buses. It can also hold two U.S. Army M-1 battle tanks that weigh 60 tons each. At nearly 143 feet, the length of the C-5 cargo floor is longer than the distance of the Wright brothers’ first flight.
