equipment. Like the AC-130 that preceded 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 cannon, improved avionics, and two underwing-mounted General Electric J85-GE-17 turbojet engines, adding nearly 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 Westinghouse J34 turbojet engine in a nacelle above the fuselage.

Two months later, the C-119 deployed with the 314th Troop Carrier Group and served in Korea throughout the war. In December 1950, after People's Republic of China Expeditionary People's Volunteer Army troops blew up a bridge {{#tag:ref|The Chinese actually blew up three bridges in succession at the same point: the original concrete span, a wooden replacement, and a third M-2 steel treadway portable bridge installed by U.S. combat engineers.<ref>Mossman, Billy C., EBB AND FLOW: NOVEMBER 1950 – JULY 1951, p. 137.</ref> |group=N}}at a narrow point on the evacuation route between Koto-ri and Hungnam, blocking the withdrawal of U.N. forces, eight U.S. Air Force C-119 Flying Boxcars flown by the 314th Troop Carrier Group were used to drop portable bridge sections by parachute. The bridge, consisting of eight separate sixteen-foot long, 2,900-pound sections, was dropped one section at a time, using two parachutes on each section. Four of these sections, together with additional wooden extensions were successfully reassembled into a replacement bridge by Marine Corps combat engineers and the US Army 58th Engineer Treadway Bridge Company, enabling U.N. forces to reach Hungnam. From 1951 to 1962, C-119C, F and G models served with U.S. Air Forces in Europe (USAFE) and Far East Air Forces (FEAF) as the first-line Combat Cargo units, and did yeoman work as freight haulers with the 60th Troop Carrier Wing, the 317th Troop Carrier Wing and the 465th Troop Carrier Wing in Europe, based first in Germany and then in France with roughly 150 aircraft operating anywhere from Greenland to India. A similar number of aircraft served in the
