replacement personnel. Cold War Tactical Missile Training The squadron was activated for a second time on 15 March 1957 as the 24th Tactical Missile Squadron and assigned to Ninth Air Force's 589th Tactical Missile Group (TMG). It trained for operation of TM-61 Matador tactical cruise missiles at Orlando AFB. When the 17th Tactical Missile Squadron deployed to Taiwan in April 1958, the 24th was transferred to the 588th TMG. It engaged in crew training with the 589th but never received any missiles or deployment orders before inactivating. The 24th and 588th TMG were programmed to deploy to South Korea during the fall of 1958, but instead, the unit was inactivated on 15 July 1958. The personnel and equipment of the 588th were reassigned to the newly formed 58th Tactical Missile Group at Osan AB, South Korea, while the 310th Fighter-Bomber Squadron at Osan gave up its F-86 Sabres and became the 310th Tactical Missile Squadron, becoming a Matador squadron and absorbing the personnel of the 588th TMG en masse.

It stood alert during the Cold War, with IM-99A (later CIM-10) BOMARC surface to air antiaircraft missiles. The squadron was tied into a Semi-Automatic Ground Environment (SAGE) direction center which could use analog computers to process information from ground radars, picket ships and airborne aircraft to accelerate the display of tracking data at the direction center to quickly direct the missile site to engage hostile aircraft. It was inactivated on 30 April 1972. The BOMARC missile site was located northeast of Duluth MAP at . Although geographically separated from the base, it was an off base facility of Duluth MAP and the squadron received administrative and logistical support from the military facilities at Duluth Airport.
