Lockheed C-141 Starlifter

Quad Jet

The Lockheed C-141 Starlifter was America's first purpose-built jet-powered strategic airlifter, entering service with the U.S. Air Force in 1965 and serving as the backbone of long-range military airlift for four decades. Before the Starlifter, the Air Force relied on converted civilian designs and piston-powered transports; the C-141 brought turbofan efficiency and pressurized cargo capability to intercontinental logistics, enabling rapid deployment of troops and equipment worldwide during the Cold War. Its high-wing design and rear loading ramp allowed straight-in loading of vehicles and palletized cargo, while four Pratt & Whitney TF33 turbofans gave it the range to cross the Pacific or Atlantic without refueling. The original C-141A proved so successful that the entire fleet was stretched 23 feet in the 1970s to create the C-141B, increasing cargo volume by nearly a third and adding in-flight refueling capability. The Starlifter became famous for its role in Operation Homecoming, repatriating American POWs from Vietnam in 1973, and for countless humanitarian missions including disaster relief and medical evacuations. It could cruise at 41,000 feet and Mach 0.77, faster and higher than most contemporary cargo aircraft, and its pressurized hold allowed aeromedical missions with intensive-care patients. The type was retired from active USAF service in 2006, replaced by the larger C-17 Globemaster III, though a handful remained in use with contractors and test organizations for several more years.
