The squadron was redesignated the 563d Fighter-Bomber Squadron and activated at Clovis Air Force Base, New Mexico in November 1953.
 The squadron was equipped with North American F-86F Sabres, with a capability of carrying nuclear weapons.
 A year after activation, in November 1954, the squadron was transferred to United States Air Forces Europe and departed, along with other elements of the 388th Fighter-Bomber Wing, for Étain-Rouvres Air Base, France.
 However, construction at Etain was not far enough advanced to permit it to accept fighter aircraft, and only the wing headquarters settled in to the base.
 Instead, the squadron ferried their Sabres to Bitburg Air Base, Germany, arriving the following month.

Little flying was done in the squadron's first winter in Europe due to weather.
 It deployed to Wheelus Air Base, Libya in April 1955, where it was able to train in gunnery and bombing for the first time since arriving in Europe.
 The squadron rejoined the wing at its permanent base in France in July 1955, the first of the wing's squadrons to arrive.
 Starting in November 1955, it began deployments to Detachment 1 of the 388th Wing at Hahn Air Base, Germany to stand nuclear alert.
 The detachment moved to Spangdahlem Air Base, Germany in February 1956.

The unit flew support for the Suez Canal and Hungarian crises.
 It converted to North American F-100 Super Sabre aircraft on 2 April 1957 and was inactivated shortly after on 10 December 1957.
 In August 1956, the squadron began training to convert to the North American F-100 Super Sabre.
 The conversion was completed by May 1957.
 However, the squadron flew the "Hun" for less than a year.
 On 10 December 1957, the 49th Fighter-Bomber Wing moved from Japan on paper to replace the 388th Wing,  The 563d was inactivated and its mission, personnel and aircraft transferred to the 9th Fighter-Bomber Squadron.
