World War II Organization and training in the United States The
squadron was first activated as the
454th Bombardment Squadron at
Columbia Army Air Base, South Carolina on 4 August 1942 as one of the four original squadrons of the
323d Bombardment Group. After Phase I training at
MacDill Field, Florida with
Martin B-26 Marauders, the squadron trained for combat at
Myrtle Beach Bombing Range, South Carolina until late April 1943, when the ground echelon departed Myrtle Beach for England, sailing on the on 5 May. The air echelon of the squadron had moved to
Baer Field, Indiana in February. At Baer, it received new B-26Cs, then proceeded to the United Kingdom via the
South Atlantic ferry route by June.
Combat in Europe The squadron arrived at its first combat station,
RAF Horham, in May 1943. In June 1943, the squadron, along with all other B-26 units in England, moved to
Essex, an area where it was planned to build up a tactical air force for the forthcoming invasion of Europe, with the 454th arriving at
RAF Earls Colne on 14 June. It began operations with
Eighth Air Force in July 1943 as part of the first medium altitude raid on the European continent by B-26s. The squadron flew a mix of trainers and
Douglas A-26 Invaders. The unit was manned at only 25% of its normal strength. All reserve combat units, including the 454th, were mobilized for the
Korean War. The squadron was
mobilized on 10 March 1951. Its personnel and aircraft were used as fillers for other organizations and the squadron was inactivated a week later.
Fighter operations The squadron was redesignated the
454th Fighter-Bomber Squadron and activated at
Bunker Hill Air Force Base, Indiana on 8 August 1955, when the Air Force reopened the base, a former World War II Navy training station. The squadron was initially equipped with
North American F-86 Sabres, but soon began upgrading to the supersonic
North American F-100 Super Sabre. However, the squadron, along with all other elements of the
323d Fighter-Bomber Wing, was inactivated on 1 September 1957, when
Tactical Air Command transferred Bunker Hill to
Strategic Air Command.
Navigator training On 1 April 1973, the squadron was activated as the
454th Flying Training Squadron. It continued to conduct undergraduate
navigator training for USAF,
United States Navy,
United States Marine Corps, and United States allies until 1993. In 1989, the base closure commission recommended that Mather be closed. The Air Force moved its navigator training to
Randolph Air Force Base, Texas and the squadron was inactivated on 31 May 1993 as Mather drew down in preparing for closing on 1 October 1993. ==Lineage==
