The 77th and later Squadron "A" provided personnel for base administrative activities and for various positions needed to maintain operations on Barron Field.

A letter from the Office Director Military Aeronautics Operations Section to Commander Barron Field dated 23 September 1918 requests that the records for the 77th Aero Service Squadron (renamed Squadron "A" by this time) be sent to Aviation General Supply Depot and Concentration Camp, Garden City, Long Island, New York for reorganization of the 77th.

In January 1943, the 77th settled at March Field, California, in time to be reassigned to England and the European Theater of Operations during World War II.

The 77th, now designated a fighter squadron, arrived at RAF Kings Cliffe, Northamptonshire, England, in August 1943, flying the P-38.

In 1957, the squadron transitioned to the North American F-100 Super Sabre and a year later was designated a tactical fighter squadron flying the "Hun" for 11 more years as part of the North Atlantic Treaty Organization defence against the Soviet Union and Warsaw Pact.

In 1969, the 77th and the 20th Tactical Fighter Wing began moving to RAF Upper Heyford and converted to the fighter-bomber version of the General Dynamics F-111 Aardvark, utilizing the F-111E model.

The 77th Fighter Squadron was inactivated on 30 September 1993 and then reactivated at Shaw Air Force Base, South Carolina, on 1 January 1994.

From February 2003 to May 2003, the squadron deployed to Prince Sultan Air Base, Saudi Arabia Asia in support of Operation Iraqi Freedom.

One F-16, piloted by Captain Lee Bryant, was able to land safely at Charleston Air Force Base, South Carolina.

[4] Air Combat Command officials announced a stand down and reallocation of flying hours for the rest of the fiscal year 2013 due to mandatory budget cuts.

The across-the board spending cuts, called sequestration, took effect 1 March when Congress failed to agree on a deficit-reduction plan.
