428th Bombardment Squadron

The 428th Electromagnetic Warfare Flight is an active Air Force Reserve Command unit, stationed at Peterson Space Force Base, Colorado. It is a reserve associate squadron of the 4th Electromagnetic Warfare Squadron of the United States Space Force.

The squadron was first active during World War II as the 39th Reconnaissance Squadron, becoming a medium bomber as the 428th Bombardment Squadron a month after it was activated. After training in the United States, it deployed to the Mediterranean Theater of Operations, where it participated in Operation Torch, the invasion of North Africa. It moved forward with American ground forces. The squadron was awarded a two Distinguished Unit Citations for its actions in combat. Following V-E Day, the squadron was inactivated in theater.

The squadron was assigned to the 310th Bombardment Wing at Schilling Air Force Base, Kansas, where it was active from February 1959 to 1 January 1962. It was inactivated when Strategic Air Command's alert commitments changed.

Mission
The 428th Electromagnetic Warfare Flight is an associate to the regular 4th Electromagnetic Warfare Squadron in partnership to train, equip, mobilize and employ space electromagnetic warfare capabilities to support national security objectives. The reservists provide knowledge of orbital mechanics, satellite command-and-control and mission planning concepts to bolster surge capacity for this mission.

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. A portion of the ground echelon sailed for the United Kingdom aboard the RMS Queen Mary on 5 September 1942, while the remainder sailed directly for North Africa from the United States. The air echelon ferried the squadron's Mitchells via the North Atlantic ferry route, but bad weather delayed their movement, with the bombers arriving at RAF Hardwick between October and December 1942.

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. The squadron engaged primarily in air support and interdiction in Tunisia, Sicily, Sardinia, Corsica, Italy and Southern France. Through May 1943, it also attacked shipping and harbor facilities to cut the logistics lines of the Afrika Corps. It bombed marshalling yards, rail lines, highways, bridges, viaducts, troop concentrations, gun emplacements, shipping, harbors and other objectives in North Africa. It moved forward to Tunisia with the allied forces, locating at Dar el Koudia Airfield in June. It bombed airfields, landing grounds and gun emplacements, supporting Operation Corkscrew, the reduction of Pantelleria and Lampedusa islands during June 1943. The following month it supported Operation Husky, the invasion of Sicily.

On 27 August 1943, the squadron conducted a mission against marshalling yards in Benevento, Italy. Despite heavy antiaircraft artillery, it effectively bombed the target and destroyed several enemy interceptor aircraft making persistent attacks. For this action, it was awarded the Distinguished Unit Citation (DUC). From August 1943 to the end of hostilities in the spring of 1945, it struck German lines of communication, bridges, rail lines, marshalling yards, viaducts, tunnels and road junctions in Italy. From January through June 1944, it gave air support to ground forces in the drive toward Rome. The squadron also engaged in psychological warfare missions, dropping propaganda leaflets behind enemy lines.

In August 1944, it supported Operation Dragoon, the invasion of southern France from its base in Ghisonaccia Airfield, Corsica. On 10 March 1945, the squadron maintained close formation in the face of severe antiaircraft fire in successfully attacking the railroad bridge at Ora, a vital link in the German supply line to Italy. For this action, it was awarded its second DUC. In April 1945, it moved to Italy and was inactivated in theater in September 1945.

Strategic Air Command
From 1958, the Boeing B-47 Stratojet wings of Strategic Air Command (SAC) began to assume an alert posture at their home bases, reducing the amount of time spent on alert at overseas bases. The SAC alert cycle divided itself into four parts: planning, flying, alert and rest to meet General Thomas S. Power’s initial goal of maintaining one third of SAC’s planes on fifteen minute ground alert, fully fueled and ready for combat to reduce vulnerability to a Soviet missile strike. 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.
