retired with appropriate ceremonies and "Open House". Air Force and civilian personnel of the base, and civilians from surrounding communities were on hand to bid the "Peacemaker" a fond farewell. This last flight of a B-36 phased out completely the B-36 program in the wing. B-52 Stratofortress and KC-135 Stratotanker Era On 10 December 1957, the 98th Bomb Squadron was detached from the wing and assigned to the newly activated 4123rd Strategic Wing at Carswell. This would become the first Boeing B-52 Stratofortress unit at Carswell. The 7th Bomb Wing officially became a B-52 organization with the adoption of manning documents and equipping authorizations on 1 February 1958. On 19 February 1958, the 4123d Strategic Wing took possession of the first Boeing B-52 Stratofortress on Carswell. At the arrival ceremony on base, the bomber was named "The City of Fort Worth". It was subsequently assigned to the 98th Bombardment Squadron of the wing. Shortly following the arrival of B-52 bombers to the 4123rd Strategic Wing, the unit was moved to new facilities at Clinton-Sherman AFB, Oklahoma. With the acquisition of the Boeing B-52 Stratofortress, all new B-52 wings would operate with an air refueling squadron to support those bombers. As a result, SAC activated the 7th Air Refueling Squadron at Carswell on 1 April 1958 and assigned it to the wing. The squadron would be equipped with the Boeing KC-135 Stratotanker later in the year. With the disestablishment of the Strategic Air Command in 1992, the 7th Air Refueling Squadron and its KC-135As were reassigned to the newly established Air Mobility Command (AMC) and the 19th Air Refueling Wing, Robins AFB, Georgia, but remained as Det. 1 at Carswell AFB until the squadron was disestablished later in 1992. Most of the 7th's KC-135As were retired to AMARG, while 55-3130, the oldest KC-135 then flying retired to the Air Force Museum at March AFB, California. A few of the 7th's KC-135As were delivered to Boeing-Wichita at McConnell AFB to be converted to the KC-135R configuration. In early 1992, SAC was ordered by AFCOS General McPeak to ground all B-52 Tail Gunners and remove the tail guns from all B-52s that were to remain in the USAF inventory. The 20mm Guns were removed from the Carswell AFB and Minot AFB based B-52Hs, while all B-52Gs kept their quad .50 caliber M-3 BMGs because they were all programmed for retirement to Davis Monthan
