World War II Initial organization and training The
squadron was activated at
Davis-Monthan Field in March 1942 as the
39th Reconnaissance Squadron, one of the four original squadrons of the
310th Bombardment Group. It moved the same day to
Jackson Army Air Base, Mississippi, where it began training with
North American B-25 Mitchells. A little over a month later, the squadron became the
428th Bombardment Squadron.
Combat in the Mediterranean heater In November 1942, the squadron flew its planes to
Mediouna Airfield, French Morocco, to support
Operation Torch, the invasion of North Africa, although some remained behind in England until as late as March 1943. To implement this new system B-47 wings reorganized from three to four squadrons. The 428th was activated at
Schilling Air Force Base as the fourth squadron of the
310th Bombardment Wing. The alert commitment was increased to half the squadron's aircraft in 1962 and the four squadron pattern no longer met the alert cycle commitment, so the squadron was inactivated on 1 January 1962.
Space operations The squadron was redesignated the
428th Electromagnetic Warfare Flight and activated at
Peterson Space Force Base, Colorado on 28 February 2023. It absorbed the mission, personnel, and equipment of Detachment 1,
710th Operations Group, which had been organized on 17 September 2021. ==Lineage==
