About the Boeing C-135

The Boeing C-135 Stratolifter represents one of aviation's most enduring military platforms, entering service in 1957 as the United States Air Force's first jet-powered aerial refueling tanker and strategic transport. Derived from the Boeing 367-80 prototype that also spawned the commercial 707, the C-135 family has served continuously for over six decades across dozens of specialized variants. The most numerous variant, the KC-135 Stratotanker, has refueled virtually every U.S.

military aircraft type and remains the backbone of American aerial refueling operations with over 400 still flying after multiple re-engining programs. The RC-135 reconnaissance variants, including the Rivet Joint signals intelligence platform, conduct critical electronic surveillance missions worldwide, bristling with antennas and sensor arrays that make them among the most capable airborne intelligence collectors ever built. Other specialized versions include the OC-135 Open Skies treaty observation aircraft, the WC-135 Constant Phoenix nuclear detection platform, and various testbed configurations.

The type's four-engine layout provides exceptional reliability for extended missions, with modern KC-135R models powered by CFM56 turbofans delivering significantly improved fuel efficiency and performance over the original J57 turbojets. Operating at altitudes up to 50,000 feet with intercontinental range, C-135s routinely conduct 15-hour sorties supporting combat operations, strategic reconnaissance, and treaty verification. The callsigns MAVRK and OLIVE reflect the diverse mission sets these aircraft perform, from routine training to sensitive intelligence gathering.
