The 1600th Air Transport Group is a discontinued United States Air Force unit. It was last assigned to the Atlantic Division, Military Air Transport Service at Westover Air Force Base, Massachusetts. It provided strategic airlift between the United States and Europe until it was discontinued on 19 June 1955.

Westover Air Reserve Base is an Air Force Reserve Command (AFRC) installation located in the Massachusetts communities of Chicopee and Ludlow, near the city of Springfield, Massachusetts. Established at the outset of World War II, today Westover is the largest Air Force Reserve base in the United States, home to approximately 5,500 military and civilian personnel, and covering 2500 acres (10 km²). Until 2011, it was a backup landing site for the NASA Space Shuttle and in the past few years has expanded to include a growing civilian access airport sharing Westover's military-maintained runways. The installation was named for Major General Oscar Westover who was commanding officer of the Army Air Corps in the 1930s.
