The 373d Strategic Missile Squadron is an inactive United States Air Force unit that was first established during World War II. After a series of inactivations and reactivations, the squadron was last assigned to the 308th Strategic Missile Wing, stationed at Little Rock Air Force Base, Arkansas. The 373rd was equipped with the LGM-25C Titan II Intercontinental ballistic missile in 1962, with a mission of nuclear deterrence. The squadron was inactivated for the last time as part of the phaseout of the Titan II ICBM on 18 August 1987, as ordered by President Ronald Reagan.
