The 150th Special Operations Squadron (150 SOS), equipped with the C-32B aircraft, is a unit of the 108th Wing of the New Jersey Air National Guard.

The squadron was stationed at Newark Municipal Airport until 1965, when it moved to McGuire Air Force Base, New Jersey.

The Constellations were retired in 1973, being replaced with the de Havilland Canada C-7 Caribou light transport, which was withdrawn from service in the Vietnam War.

In September 1994, for over 30 days, five aircraft and 300 squadron members deployed to Pisa International Airport, Italy for Operation Deny Flight.

Its aircraft do not carry standard United States Air Force markings, and the serial/registration numbers they display are subject to change.

At the rear of the cabin, the usual cargo space in the hold has been reconfigured to accommodate enlarged fuel tanks, extending the aircraft's unrefueled maximum range to 6000 nautical miles.
