| To meet the US Air Force 1956 UCX requirement for flight proven utility transport, Lockheed produced its Model 1329 design to meet both this need and the burgeoning world market for executive jet CL-329 JetStar prototype first flew in September 1957 with two 4,850-lb thrust Bristol Siddeley Orpheus could not be finalized by Wright Lockheed was force to recast the plane with four 3,000-lb thrust JT12A-6 turbojets. The 1957 US defense budget cuts eliminated the UCX requirements, but lockheed eventually received small military orders totaling 16 aircraft. The five C-140A were nav/aid calibration aircraft similar to the civil JetStar 6 with a lengthened fuselage, and were delivered from September 1961. The five C-140Bs were utility transport convertible between the passenger and high priority freight roles. The six VC-140Bs were later upgraded to this standard. |
