Mikoyan-Gurevich MiG-17, part two, European users

The Mikoyan-Gurevich MiG-17 is a high-subsonic fighter aircraft made mainly in the USSR from 1952 and operated by many world's air forces in many variants. It was an advanced development of the previous MiG-15 which showed excellent results during the Korean War. It was also built under license in China, as Shenyang J-5 and in Poland as WSK-Mielec Lim-6.
It was employed in combat for the first time during the Second Taiwan Strait Crisis and later proved to be effective against the more advanced supersonic fighters of the United States during the Vietnam War. Prior to the official NATO designation, it was known by the United States Air Force as Type 38.
The first variant, called just "MiG-17" (NATO code "Fresco-A") was the basic fighter version powered by the Klimov VK-1 engine which delivered a power of 26.48kN (5952lb) of thrust, with some versions retrofitted later with the improved Klimov VK-1A which yielded 26.87kN (6041lb) of power.
It was armed with a single 37mm N-37D cannon, two 23mm NR-23 cannons and could carry up to 250kg of bombs or external fuel depots, which was the most usual underwing addition.
The basic variant, was used, among others, by the next European users:

• Albania: Just before the Soviet-Albanian Split of 1955, the Albanian People's Army Air Force received some MiG-17s. Their operational use and/or fate is unknown and, as we couldn't find graphical evidence, the drawing should be taken as speculative.
• East Germany: The first fighters of the Air Forces of the National People's Army, founded in 1956, were MiG-17s and MiG-17Fs which served together until mid-1960s when they were replaced by the more advanced MiG-19 and MiG-21.
• USSR: The main user of the MiG-17. More than 5467 exemplar built in many Soviet factories from 1952 until 1955. They were the main Soviet fighter until 1955 when they were gradually replaced by the more advanced variant MiG-17F.

Aero L-29, part four, various European users users

As we've previously said many time, the Aero L-29 was used by many Eastern bloc countries. The ones covered in this post are:

• Hungary: As it happened with almost every other Warsaw Pact country, Hungary bought a number of Aero L-29 in the mid 1960s (in 1965 to be more precise) to equip their training squadrons. They served until the fall of communism in 1989 together with other more advanced and modern types. 
• Romania: Being a Warsaw Pact member, the Romanian Air Force was supplied with a number of Aero L-29 to equip their training squadrons and flight schools. They served until the fall of communism in 1989 and shortly beyond, together with other types.
• Slovakia: After the creation of the Slovak Air Force in 1993, there were many L-29s left in the country which served as the main trainer for the newly created air force. It served alongside the more advanced Aero L-39 until the very late 1990s when it was phased out.
• USSR: The Soviet Air Force (VVS) was the main user of the Aero L-29. It served as its main trainer, together with other types until the dissolution of the USSR in 1992.
