Lockheed C-140A JetStar, S/N 59-5962
The Lockheed C-140A JetStar was a military variant of the civilian JetStar business jet, developed by Lockheed Corporation in the early 1960s. Originally designed as one of the first dedicated business jets, the JetStar was adapted for U.S. military use as a fast, reliable transport and communications platform. The C-140A was procured by the U.S. Air Force to support specialized missions requiring rapid personnel movement and airborne command capabilities, reflecting a growing need for flexible, jet-powered support aircraft during the Cold War era.
Unlike standard passenger configurations, the C-140A was equipped for airborne communications relay and operational support roles. It featured advanced radio systems and mission equipment that allowed it to function as a communications node, particularly in support of the Military Airlift Command. The aircraft retained the JetStar’s distinctive four-engine configuration—two engines mounted on each side of the rear fuselage—which provided strong performance, redundancy, and the ability to operate from a variety of airfields. Its relatively small size and speed made it well-suited for quick-response missions and high-priority transport.
Throughout its service life, the C-140A proved to be a versatile and dependable aircraft, supporting a range of missions including command support, liaison transport, and communications augmentation. While only a limited number were produced, the aircraft filled an important niche by bridging the gap between larger transport aircraft and smaller utility platforms. The JetStar family, including the C-140A, remained in service for decades in various roles, leaving a legacy as one of the pioneering designs in both business and military jet aviation.
