The Lockheed L-100 Hercules was the Lockheed Corporation's less successful civilian variant of the prolific C-130 military transport aircraft. Its first flight occurred in 1964. Longer L-100-20 and L-100-30 versions were developed. L-100 production ended in 1992 with 114 aircraft delivered.


In 1959, Pan American ordered 12 GL-207 Super Hercules to be delivered by 1962, it was to be powered by four 6,000 eshp Allison T61 turboprops. It was to be 23 ft 4 in (7.11m) longer than the C-130B, a variant powered by 6,445 Rolls-Royce Tynes and a jet-powered variant with four Pratt & Whitney JT3D-11 turbofans were also under development. Both Pan American and Slick Airways (who had ordered six) cancelled their orders and the other variants did not evolve past design studies. The company then decided to produce a commercial variant which was just a de-militarised version of the C-130E Hercules. The prototype L-100 (N1130E) first flew on the 20 April 1964 when it carried out a 25 hour 1 minute flight. The type certificate was awarded on 16 February 1965. Twenty-one production aircraft were then built with the first delivery to Continental Air Services on 30 September 1965.

Slow sales led to the development of two new, longer versions, the L-100-20 and L-100-30, both of which were larger and more economical than the original model. Deliveries totaled 114 aircraft, with production ending in 1992. An L-100J variant of the updated C-130J was cancelled in 2000.


Civilian variants are equivalent to the C-130E model without pylon tanks or military equipment.
