The Boeing 767’s rise as the United States Air Force’s primary tanker is one of the hardest-fought comebacks in modern aviation. By December 2025, the USAF had accepted 100 KC-46 Pegasus aircraft into service, marking a major step in replacing the KC-135 Stratotanker fleet that has been flying since the late 1950s. According to Boeing and US Air Force fact sheets, the KC-46A carries up to 212,000 pounds of fuel, uses Pratt & Whitney PW4062 engines, and integrates elements from a 787 cockpit, bringing a Cold War mission into the digital age.
