During World War I, the squadron was based at Toul (5 May 1918), Touquin (28 June 1918), Saints (9 July 1918) and Rembercourt (1 September 1918).

In the period between the world wars, the 27th Pursuit Squadron, re-designated 25 January 1923, was stationed primarily at Selfridge Field, Michigan, with the 1st Fighter Group.

A large silhouette of a battleship on the grass landing strip served as a target, which was successfully strafed and bombed for several duly impressed congressmen.

Following World War II, the 27th was stationed at March Field, California, flying P-80 Shooting Stars, the United States' first operational jet aircraft.

The 27th TFS deployed in support of Operation Desert Storm as part of the first U.S. Air Force contingent in Saudi Arabia.

The 27th Fighter Squadron today stands as a cohesive combat experienced team ready for any call to support the United States' security requirements.

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.
