Boeing responded by developing the Model 367-80, commonly known as the “Dash 80,” which served as the prototype for both the KC-135 Stratotanker and the Boeing 707 commercial airliner. The KC-135 made its maiden flight on August 31, 1956, and the first production model was delivered to Castle Air Force Base, California, in June 1957. Production continued until 1965, with a total of 803 units built. Engine Retrofits Originally equipped with Pratt & Whitney J57-P-59W turbojet engines, the A models were later upgraded to more efficient turbofan engines. The most significant upgrade involved re-engining over 417 aircraft with CFM International CFM-56 engines, designated as KC-135R models. This retrofit enhanced fuel efficiency, reduced noise levels, and improved operational performance. Avionics Upgrades To keep pace with technological advancements, the fleet has undergone multiple avionics upgrades. These enhancements include modernized navigation systems, communication suites,… Read More »KC-135 Stratotanker
