On 10 July 1952, the 123d Fighter-Bomber Wing at RAF Manston, England was released from federal service and returned to the Kentucky Air National Guard, while its personnel and equipment were transferred to the newly activated 406th Fighter-Bomber Wing. The fighter squadrons being replaced by the 512th, 513th and 514th respectively, the F-84G Thunderjets and support aircraft of the ANG were assigned to the 406th Fighter-Bomber Group. The 406th FBW commanded the functions of both the support groups as well as the flying combat 406th FBG. The few National Guardsmen still with the wing departed and the last were released from active duty on 9 July, although a few reserve officers remained on active duty for an additional six to twelve months.
