History of the Boeing KC-135 Stratotanker
Development of the KC-135 began in the early 1950s, with the US Air Force requiring a new tanker aircraft to replace the aging KB-29M. Boeing won the contract in 1951, and the KC-135 made its first flight in 1956. The aircraft was designed to meet the needs of the Strategic Air Command (SAC), which required a tanker that could refuel bombers and fighters at high altitudes and speeds. The KC-135 was designed to be a multi-role aircraft, capable of both refueling and transporting cargo or personnel.
Throughout its service life, the KC-135 has undergone numerous upgrades and modifications to improve its performance and capabilities. In the 1960s, the KC-135A was introduced, featuring a more powerful engine and improved avionics. The KC-135E, introduced in the 1970s, featured a more advanced avionics system and improved fuel efficiency. The KC-135R, introduced in the 1980s, featured a more powerful engine and improved refueling capabilities. The KC-135R is the variant that is most closely associated with the K35R designation.
