The 133rd Air Refueling Squadron (133 ARS) is a unit of the New Hampshire Air National Guard 157th Air Refueling Wing located at Pease Air National Guard Base, Portsmouth, New Hampshire, United States. The 133rd, which previously operated the KC-135 Stratotanker, received its first KC-46A Pegasus tanker on 8 August 2019.
The squadron was first constituted during World War II, with bombardment and fighter roles—as the 383rd and 529th, respectively—until being inactivated in January 1946. It was then allotted to the New Hampshire Air National Guard as the 133rd Fighter Squadron in May 1946, being activated the following April. From 1960 until 1975, the 133rd went through several operational changes: air transport, military airlift, tactical airlift, and finally aerial refueling, which remains its current mission. The 133rd has been federalized and ordered to active service several times; 1951–52, 1961–62, and 1990–91.
