I found some more information about the MiG19 and its variants. North Korea has the J-6, that's a Chinese version of the MiG19.
Development dates back as far as 1953 (!), I guess I should have posted that in the "Aviation History" forum.
Here's some more info on the MiG19 and F/J-6:
MiG-19 FARMER
J-6 / F-6
The MiG-19 Farmer was the first supersonic fighter built in the former USSR. The MiG-19 prototype made its first flight in September 1953 and was placed into production in 1955. It was the Soviet Union's primary fighter during the last half of the 1950's. Possibly as many as 10,000 MiG-19's, in various versions, were built by the Soviet Union, China, Poland, and Czechoslovakia. About 2,000 have been built in the People’s Republic of China. Many other countries used the MiG-19, including Cuba, North Vietnam, North Korea, Iraq, and most of the Warsaw Pact nations. The Soviet Union phased out the MiG-19 in the early 1960s in favor of the more advanced MiG-21. However, the MiG-19 continued to be used by the other nations for many more years.
The F-6 (Jianjiji-6 Fighter aircraft 6) is the Chinese version of the MiG-19, which as of the mid-1990s was still in production in China. The J-6, which began flight tests in 1958, was China's first supersonic jet fighter. The F-6 has six attachment points for external stores (three on each wing). The outboard wing stations can carry a 250 kg bomb. The outboard wing stations can also carry a 760 or 400 liter drop tank or the CAA-1b AAM. The inboard wing stations can carry practice bombs or rocket pods with either 8 x 57mm, 16 x 57mm, or 7 x 90mm rockets.
The aircraft's wings are mid-mounted, swept-back, and tapered with blunt tips. There are wing fences and wide wing roots. There are two turbojet engines mounted inside the body and a single, round air intake in the nose. Note that what appears to be a single air intake is actually separated on the inside with each engine drawing air from its own intake. Two aircraft that have a single air intake with two engines are the Lightning and the G.91Y. There are dual exhausts. The fuselage is long, tube-shaped, and tapers slightly to the blunt nose and widens to the exhausts. There is a bubble canopy well forward on the nose. The tail fin is sharply swept-back and tapered with blunt tips. Flats high-mounted on the fuselage and swept-back with blunt tips
