the unit was re-designated as the 157th Air Refueling Wing. The 133rd was assigned to the new 157th Operations Group. A month later, on 1 June, Strategic Air Command was inactivated as part of the Air Force reorganization after the end of the Cold War. It was replaced by Air Combat Command (ACC). In 1993, ACC transferred its KC-135 tanker force to the new Air Mobility Command (AMC). By mid-1993, the 157th was reorganizing, bringing the 157th in line with current Air Force restructuring guidelines. The 133rd's 10 KC-135E-model aircraft were replaced throughout the summer with quieter, more efficient R-models. With their new CFM-56 engines, a 50 percent decrease in noise resulted, and emissions were reduced 90 percent, while range, fuel off-load capability, and reliability were all increased. By January 1994 all the unit's KC-135's had been converted to R-Models. The unit engaged in routine deployments and training until 1994 when the 157th began operating in the Northeast Tanker Task Force together with the Maine Air National Guard. The situation in Bosnia-Herzegovina and "Operation Deny Flight" continued to involve 157th aircraft, crews, and support personnel. In December, 52 unit members deployed with Niagara Falls' 107th Air Refueling Wing to Pisa Airport, Italy. At Pease, "Operation Phoenix Moat" missions required 157th participation to help with the flow of personnel and materiel to the area. The mission in Bosnia was renamed "Joint Endeavor" and, finally, "Decisive Endeavor," as the crisis cooled. Consolidating assets, the Air Guard left Istres AB, France, and operated exclusively out of Pisa, rotating units through on a month-to-month basis. The 157th's turn came again in October 1996, as 207 unit members swapped in and out of the Italian air base for the month. By 1997, the 157th had already been rotating 145 members through Incirlik Air Base, Turkey, as part of "Operation Northern Watch", enforcing the no-fly zone over northern Iraq. Three months later, in February 1998, the 157th, augmented by four transient aircraft, flew 28 sorties offloading gas to an air convoy carrying Army personnel and equipment from Georgia to the theater area. In the face of mounting U.S. military might, Saddam Hussein backed down. The year 2000 saw the 157th provide support to Operation Joint Forge as well as other operational and training missions. During Operation Joint Forge, the 157th flew 55 sorties, off-loading over one and one half million pounds of fuel to operational fighters
