The Lockheed L-100 Hercules is the civilian variant of the prolific 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. L-100 production ended in 1992 with 114 aircraft delivered.[1][2] An updated variant of the model, LM-100J, has completed its first flight in Marietta, Georgia on 25 May 2017, and was set to start production in 2018–19.[3]

Development

In 1959, Pan American World Airways ordered 12 of Lockheed's GL-207 Super Hercules to be delivered by 1962, to be powered by four 6,000 eshp Allison T56 turboprops.[4] Slick Airways was to receive 6 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. Both Pan American and Slick Airways (which had ordered six) cancelled their orders and the other variants did not evolve past design studies.

Lockheed decided to produce a commercial variant based on a de-militarised version of the C-130E Hercules.[citation needed] The prototype L-100 (registered N1130E) first flew on 20 April 1964 when it carried out a 1-hour, 25-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.[citation needed] Deliveries totaled 114 aircraft, with production ending in 1992. Several L-100-20 aircraft were operated on scheduled freight flights by Delta Air Lines between 1968 and 1973.

An updated civilian version of the Lockheed Martin C-130J-30 Super Hercules was under development, but the program was placed on hold indefinitely in 2000 to focus on military development and production.[1][2] On 3 February 2014, Lockheed Martin formally relaunched the LM-100J program, saying it expects to sell 75 aircraft. Lockheed sees the new LM-100J as an ideal replacement for the existing civil L-100 fleets.[5]

The launch operator for the LM-100J will be Pallas Aviation, from 2019 they will operate two aircraft from Fort Worth Alliance Airport in the United States.[6] By early March 2022 the three LM-100J aircraft (tail numbers N96MG, N71KM and N67AU) then owned by Pallas had begun flying dozens of flights between Ramstein AB and secondary military air facilities at Nowe Miasto nad Pilicą, Poland; Boboc, Romania; Sliač, Slovakia; Lielvārde, Latvia and Aalborg, Denmark.

Variants

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

L-100 (Model 382)
One prototype powered by four Allison 501-D22s and first flown in 1964
L-100 (Model 382B)
Production variant
L-100-20 (Model 382E and Model 382F)
Stretched variant certified in 1968 with a new 5 ft (1.5 m) section forward of the wing and 3 ft 4 in (1.02 m) section aft of the wing.
L-100-30 (Model 382G)
A further stretched variant with an additional 6 ft 8 in (2.03 m) fuselage section.
LM-100J (Model 382J)
An updated civilian version of the military C-130J-30 model.[9]
L-400 Twin Hercules
A twin-engine variant of the C-130. It was advertised in at least one publication that it would have "more than 90% parts commonality" with the standard C-130. The aircraft was shelved in the mid-1980s without any being built.[10][11]
