Mikoyan-Gurevich Mig-19C Farmer

The Mikoyan-Gurevich MiG-19 (Russian: Микоян и Гуревич МиГ-19; NATO reporting name: Farmer) is a Soviet second generation, single-seat, twinjet fighter aircraft, the world's first mass-produced supersonic aircraft. It was the first Soviet production aircraft capable of supersonic speeds in level flight. A comparable U.S. "Century Series" fighter was the North American F-100 Super Sabre, although the MiG-19 primarily fought against the more modern McDonnell Douglas F-4 Phantom II and Republic F-105 Thunderchief over North Vietnam. This aircraft was originally used by the Soviet Union but it was later used by the People's Liberation Army Air Force.

The rush to get the MiG-19 into service resulted in initial production aircraft having a number of serious problems. The type suffered a number of in-flight explosions, eventually traced to poor insulation between the aircraft's engines and fuel tanks in the rear fuselage - overheating of these tanks could cause fuel explosions. This was eventually partly solved by fitting a metal heat shield between the engines and the tanks.[11] The aircraft's elevators proved ineffective at supersonic speeds, and an all-moving slab tail was tested by the second and third SM-9 prototypes, and later included in the major production type, the MiG-19S, which also featured an improved armament.
