was equipped with second-line KC-97L Stratotankers. In 1978, the squadron received KC-135A Stratotankers; a newer and faster jet tanker. In January 1979 the unit began the 24-hour-per-day Strategic Air Command (SAC) alert commitment. This commitment would be maintained for the next 12 years until President George Bush ended the SAC Alert Force in 1991. The 1980s found the squadron involved in many training exercises as well as "real World" flying missions. In 1982 the unit converted to a newer version model aircraft—the KC-135E. In April 1983 the 191st Air Refueling Squadron was involved in the first Pacific Tanker Task Force, with flights to Guam, South Korea and Australia. Spring of 1984 brought a very large "first" for the 1191st Air Refueling Squadron. The unit participated in Coronet Giant, an exercise which entailed a direct flight from the United States to West Germany by 12, A-10 Thunderbolt II attack fighters, refueled along the way by three KC-135's from the 191st The route spanned 3600 miles, and was the largest mission of this type ever undertaken by a guard force. During Operation Desert Shield, the squadron received orders for a partial activation on 20 December 1990. All aircraft, aircrews and a number of support personnel were dispatched to the newest forward operating base at Cairo West Airport, Egypt on 27–29 December 1990. They became the basis for the 1706th Air Refueling Wing (Provisional). Other unit personnel were mobilized for use as stateside "backfill" (replacing troops sent forward) or sent to overseas destinations. On 30 April 1999, the 151st ARG was tasked for a Presidential Reserve Call Up due to the crisis in Kosovo. President William Clinton authorized the call up of 33,000 reserve personnel for up to 270 days. The 191st deployed to Europe to support Operation Allied Force. Global War on Terrorism Following the terrorist's attacks on the United States the squadron was tasked to provide aerial refueling support for the countless fighter combat air patrols performed over major U.S. cities. Dubbed Operation Noble Eagle (ONE), the 191st ARS flew their first ONE mission on 12 September 2001. The highest sortie production occurred in November when fighter combat air patrols occurred every four hours over most of the major U.S. cities. In addition to supporting ONE, the 191st ARS also provided support for Operation Enduring Freedom (OEF), deploying aircraft and personnel to Spain to support combat air operations from late Sep
