El primer avión voló en agosto de 1956 y la producción inicial de aeronaves se entregó en junio de 1957. El último KC-135 fue entregado en 1965.De los KC-135A, más de 420 han sido modificados con los nuevos motores CFM56. El avión cisterna rediseñado, ya sea el KC-135R o el KC-135T, puede carga un 50% más de combustible, es un 25% más eficiente, tiene un coste de operación un 25% menor y un 96% más silencioso que el KC-135A.En una de las primeras modificaciones, 157 aviones fueron actualizados con la incorporación de motores Pratt & Whitney TF-33-PW-102 de aviones 707 retirados. El rediseñado KC-135E es un 14% más eficiente que el KC-135A y puede transportar un 20% más de gasolinaFuente: wikipediaRemaining in-service KC-135A's have been modified with new CFM-56 engines produced by CFM-International. The re-engined tanker, designated the KC-135R, can offload 50 percent more fuel, is 25 percent cheaper to operate and is 96 percent quieter than the KC-135A. On 20 February 2000 officials from Air Mobility Command announced the stand down of 198 out of a fleet of 546 C/KC-135 “Stratotanker” air refueling aircraft. The stand down of one-third of the Stratotanker fleet was the result of a suspected defective part that was being used to repair the aircraft’s flight controls. The Stab-Actuator, roughly a large, metal, motorized nut is located on a jackscrew assembly in the aircraft tail that allows aircrew to trim the stabilizer in flight. Officials stated the stand down measure was taken as a precautionary measure to ensure flying safety and was in no way connected with the recent crash of the Alaska Airlines ME-83. The Air Force had been in the process of replacing, what was in some cases, an original factory part in this 44-year old aircraft fleet wide when this problem surfaced. However, many KC-135s had done a lot of sitting on alert with the then Strategic Air Command, and did’t have as much total flying time on them as some of the other aircraft did. The KC-135 Reduced Vertical Separation Minimums (RVSM) modification provides increased accuracy in measuring the aircraft's altitude. The KC-135 System Program Office at Oklahoma City Air Logistics Center administered the modification, making the fleet certified for operation in RVSM airspace. Air Mobility Command issued RVSM certification for KC-135E/R tankers in January 2002. As of early April, more than 190 KC-135 aircraft had been released to operate in RVSM designated airspace. RVSM-compliant aircraft are allowed to operate at altitudes where aircraft vertical separation has been reduced to accommodate increased aircraft traffic. The RVSM designated altitudes provide optimum aircraft cruise conditions and minimize fuel consumption. Aircraft that do not comply with RVSM requirements must fly above or, primarily, below the RVSM designated altitudes and will experience increased fuel consumption and typically slower cruise speeds. As of May 2002, the Air Force had 545 KC-135 Tankers, 134 E Models and 411 R Models. In order to replace the aging E Models and thereby save maintenance costs, the Air Force proposed leasing 100 Boeing 767 Tanker/Transport aircraft to replace 127 E Models of KC-135. This plan would be completed by 2009, with seed money for the project first appearing in the FY05 budget. fuente: <a href="http://www.globalsecurity.org">http://www.globalsecurity.org</a></blockquote>
