Lockheed L-100 Hercules
civil four-engine turboprop transport aircraft
The Lockheed L-100 Hercules is the civilian variant of the C-130 Hercules military transport aircraft made by the Lockheed Corporation. Its first flight occurred in 1964. Longer L-100-20 and L-100-30 versions were developed; despite this, L-100 production ended in 1992 with 114 aircraft delivered. An updated variant of the model, LM-100J, completed its first flight in Marietta, Georgia on 25 May 2017, and started mass production in 2019. L-100 and LM-100J aircraft can be distinguished from the C-130 and C-130J military versions by the absence of side and forward windows underneath the main windshield.
Development
In 1959, Pan American World Airways (Pan Am) ordered twelve of Lockheed's GL-207 Super Hercules to be delivered by 1962, to be powered by four 6,000 eshp Allison T56 turboprops; however, Pan Am never took delivery of these aircraft. Slick Airways was to receive six such aircraft later in 1962. The Super Hercules was to be 23 ft 4 in (7.11 m) longer than the C-130B; a variant powered by 6,445 eshp Rolls-Royce Tynes and a jet-powered variant with four Pratt & Whitney JT3D-11 turbofans were also under development.
In 1960, Zantop Air Transport won a USAF Logair domestic cargo contract for bulky freight by agreeing to purchase five Lockheed C-130B transports that were to be commercially certificated by Lockheed. The agreement foundered when Zantop and Lockheed were unable to agree on financing terms.

Why this record matters
“Lockheed L-100 Hercules” is worth following because a concise public description often conceals a longer documentary argument. Here, Lockheed, L-100 and Hercules provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 13, 2026. The linked authority identifier is Q2895154. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1964, 1992, 2017 and 2019.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
