Fairchild C-119 Flying Boxcar

The Fairchild C-119 Flying Boxcar (Navy and Marine Corps designation R4Q) is an American military transport aircraft developed from the World War II-era Fairchild C-82 Packet, designed to carry cargo, personnel, litter patients, and mechanized equipment, and to drop cargo and troops by parachute. The first C-119 made its initial flight in November 1947, and by the time production ceased in 1955, more than 1,100 had been built.

The Air Force C-119 and Navy R4Q were developments of the earlier C-82A Packet, of which 223 were built between 1945 and 1948. The Packet had provided limited service to the Air Force's Tactical Air Command and Military Air Transport Service before its design was found to have several serious problems. Though the C-82A continued in service until replaced, some of these issues were addressed in the C-82B which first flew in 1947. The C-82B would later be re-classified as the C-119.

To improve pilot visibility, enlarge the cargo area, and streamline aerodynamics, the C-119 cockpit was moved forward to fit flush with the nose, rather than over the cargo compartment. The correspondingly longer fuselage resulted in more usable cargo space and larger loads than the C-82 could accommodate. The C-119 also got new engines, with 60% more power, four-bladed props to three, and a wider and stronger airframe. Despite more powerful engines, the C-119's rate of climb was unimpressive (about 770 feet per minute when loaded) and, like its predecessor, had very poor single engine climb performance (less than 100fpm at sea level with gear retracted).

The first C-119 prototype (called the XC-82B) made its initial flight 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 Fairchild-built C-119 differed from the Kaiser C-119F by the substitution of less powerful 3,500hp Wright R-3350-85 Duplex Cyclone radial engines in place of the twin 4,200 hp Pratt & Whitney R-4360 Wasp Major radials originally fitted. Kaiser built 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 never eventuated. The Kaiser sub-contract was frowned upon by Fairchild, and efforts were made through political channels to stop Kaiser's production.[citation needed] C-119s manufactured by Kaiser exhibited wrinkling of the aluminum panels surrounding the cockpit after only a few hours of use, which did not endear these models to aircrew assigned to fly them. Following Kaiser's termination of C-119 production, the contract for the C-123 was instead awarded to Fairchild.

Many 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, a few others were later shipped to Belgium and Italy.

The AC-119G Shadow gunship variant was fitted with four six-barrel 7.62 mm (0.300 in) NATO miniguns, armor plating, flare launchers, and night-capable infrared equipment. Like the AC-130 that replaced it, the AC-119 proved 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 General Electric M61 Vulcan 20 mm (0.79 in) 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.
