Development
The Air Force C-119 and Navy R4Q was initially a redesign of the earlier Fairchild C-82 Packet, built between 1945 and 1948. The Packet provided service to the Air Force's Tactical Air Command and Military Air Transport Service for nearly nine years during which time its design was found to have several serious problems. All of these were addressed in the C-119.
In contrast to the C-82, the cockpit was moved forward to fit flush with the nose rather than its previous location over the cargo compartment. This resulted in more usable cargo space and larger loads than the C-82 could accommodate. The C-119 also featured more powerful engines, and a wider and stronger airframe. The first C-119 prototype (called the XC-82B) first flew in November 1947, with deliveries of C-119Bs from Fairchild's Hagerstown, Maryland factory beginning in December 1949.
In 1951 Henry J. Kaiser was awarded a contract to assemble additional C-119s at the Kaiser-Frazer automotive factory located in the former B-24 plant at Willow Run Airport in Belleville, Michigan. Initially, the Kaiser-built C-119F would differ from the Fairchild aircraft by the use of Wright R-3350-85 Duplex Cyclone engines in place of Fairchild's use of the Pratt & Whitney R-4360 Wasp Major radial engine. The Wright engine was a proven design used previously on the B-29, and though it lacked the R-4360's superchargers it proved to be virtually identical in performance, and possibly superior at higher altitudes. Kaiser would build 71 C-119s at Willow Run in 1952 and 1953 (AF Ser. No. 51-8098 to 51-8168) before converting the factory for a planned production of the Chase C-123 that would never occur. The Kaiser sub-contract was frowned upon by Fairchild, and efforts were made through political channels to stop Kaiser's production, which may have proven successful. Following Kaiser's termination of C-119 production the contract for the C-123 was instead awarded to Fairchild. Most Kaiser-built aircraft were issued to the U.S. Marine Corps as R4Qs, with several later turned over to the South Vietnamese Air Force in the 1970s.
The AC-119G "Shadow" gunship variant was fitted with four six-barrel 7.62 mm miniguns, armor plating, flare launchers, and night-capable infrared equipment. Like the AC-130 that would succeed it, the AC-119 would prove to be a potent weapon. The AC-119 was made more deadly by the introduction of the AC-119K "Stinger" version, which featured the addition of two 20 mm cannon, improved avionics, and two underwing-mounted General Electric J85-GE-17 turbojet engines, adding nearly 6,000 lbf (27 kN) of thrust.
Other major variants included the EC-119J, used for satellite tracking, and the YC-119H Skyvan prototype, with larger wings and tail.
In civilian use, many C-119s feature the "Jet-Pack" modification, which incorporates a 3,400 lbf (15,000 N) Westinghouse J34 turbojet engine in a nacelle above the fuselage.

Famous quotes containing the word development:
“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (1848–1925)
“If you complain of people being shot down in the streets, of the absence of communication or social responsibility, of the rise of everyday violence which people have become accustomed to, and the dehumanization of feelings, then the ultimate development on an organized social level is the concentration camp.... The concentration camp is the final expression of human separateness and its ultimate consequence. It is organized abandonment.”
—Arthur Miller (b. 1915)
“To be sure, we have inherited abilities, but our development we owe to thousands of influences coming from the world around us from which we appropriate what we can and what is suitable to us.”
—Johann Wolfgang Von Goethe (1749–1832)
