The squadron participated in combat missions in World War II and the Vietnam War, provided air defense in Korea and Japan from 1968 to 1971, and continues to provide tactical air command for the United States Air Force. It currently operates McDonnell Douglas F-15E Strike Eagle aircraft, conducting close air support missions.

It provided air defense in Korea and Japan from 22 July 1968 to 14 February 1971.[1]
2013 sequestration
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.[3]
Squadrons either stood down on a rotating basis or kept combat ready or at a reduced readiness level called "basic mission capable" for part or all of the remaining months in fiscal 2013.[3] This affected the 391st Fighter Squadron with a stand-down grounding from 9 April-30 September 2013.[3]
