WSK-Mielec Lim-5, other variants

The Lim-5 was built in various variants. There was the Lim-5R which was a reconnaissance variant of the regular Lim-5, fitted with an AFA-39 camera placed under the cockpit. Only 36 exemplars were converted from regular Lim-5 in 1960 and them all served with the Polish Air Force.
The Lim-5M was an attack variant sourcing from an study made in the late 1950s looking for a light attack aircraft based on the Lim-5. As both the MiG-17 and the Lim-5 could only carry 250 kg of bombs underwings, which replaced their external fuel tanks. After the prototype, designated as 'CM' flew for the first time on 2nd June 1959, some months later, in 1960, the Poles began the production of an attack aircraft, the Lim-5M. It introduced many modifications to the fighter, most of which stressed on allowing the modified plane to be based on ground airfields. It had double undercarriage wheels, a braking parachute and sockets for RATO (Rocket Assisted Take Off). The wing sections close to the fuselage were noticeably thicker, as they contained additional fuel tanks. Instead of the two bombs, it could carry two launchers for eight 57 mm S-5 air-to-ground rockets. Sixty of them were built from 1960 until May 1961 and, in November 1961 they started to serve with the Polish Air Force, where they weren't successful as thicker wings decreased performance and made flying tricky, while increased drag meant that increased range wasn't achieved.
The Lim-5P was a Polish licensed version of the MiG-17PF. It was equipped with the Izumrud 5 (RP-5) radar and 130 of them were manufactured by WSK at Mielec from 1959 to 1960. As it was a copy of the MiG-17 it was powered by the Klimov VK-1F (named in Poland as Lis-5F) and although not many of them were built, some of them were exported. They were exported to Bulgaria, Indonesia (which we couldn't find reliable pics of them, so the drawings are speculative) and East Germany. They also served with the Polish Air Force were they were kept active until the 1980s when they were written off. At least one of them was experimentally fitted with ventral cameras under the cockpit at starboard, similar to the Lim-5R.

WSK-Mielec Lim-5

In 1955, Poland bought a license for manufacturing the Soviet MiG-17F, which was the backbone of the Warsaw Pact's fighter force. The licensed aircraft was given the denomination of "Licencyjny mysliwiec" which translates to "Licensed fighter". The first Lim-5 rolled out of the factories on 28th November 1956, replacing this way the production of the WSK-Mielec Lim-2 (a licensed production of the MiG-15bis).
The Lim-5 was virtually identical to the regular MiG-17F. It was powered by a Polish copy of the Klimov VK-1F engine with 5046 lbf of maximum thrust and 7423 lbf with afterburner. It was armed with one 37 mm N-37 cannon and two 23 mm NR-23 cannons placed under the nose. It also had provisions for underwing bombs.
Production ranged from 1956 until 1960 and, when production ceased, with 448 Lim-5 manufactured, it had become Poland's basic fighter. In fact it was the backbone of Polish Air Force's fighter force during the 1950s and the 1960s until it was replaced by more modern types such as the MiG-21 in the 1970s.
The type was exported also to various countries:

• East Germany: One-hundred and twenty Lim-5 were sold to the East German Air Force during the late 1950s. Apparently some of them had the mast at the opposite side. Just like the MiG-17F some of them were either converted to light bombers or sold to African countries. Anyway, they were replaced during the 1970s by more modern types and put into storage. When Germany was reunified, as the type was considered old and outdated for the modern Luftwaffe, they were sold to Guinea-Bissau.
• Egypt: Many of the Egyptian MiG-17F that fought in the Six-days war were Polish-built Lim-5. It's known that the Polish government sold an undefined number of Lim-5 fighters to the Egyptian Air Force. As we couldn't find a pic of a genuine Lim-5 under Egyptian command, the colours and the registration should be considered as speculative.
• Guinea-Bissau: The Guinea-Bissau Air Force bought some second-hand Lim-5 from Germany after the German reunification, as they were outdated for the modern Luftwaffe's standards. Nowadays they are put into storage. 
• Indonesia: The Indonesian Air Force had 20 Lim-5 in active service during the 1960s. Not much more is known, but most probably they were written off during the 1970s.

Mikoyan-Gurevich MiG-17PF, part three, European Users 2

With almost 700 machines manufactured, the MiG-17PF was exported to most (if not every) countries inside the Warsaw Pact. In many of these it was the first radar-equipped jet fighter. According to our sources, 698 machines were manufactured between 1954 and 1956 alone at Aerial Factories number 21 and 31 located at Gorky and Tblisi respectively. Among the various users the MiG-17PF served with, apart from those we posted in the first part (or part two, depending on your way of counting) are the following ones:

• Bulgaria: In 1955 the Bulgarian People's Air Force received a batch of MiG-17F and PFs. They served for a long time alongside the more advanced MiG-19, until the late 1970s when they were replaced by the MiG-21 and MiG-23. In fact, by 1989 there wasn't any MiG-17 of any kind in active role with the Bulgarian Air Force.
• Czechoslovakia: The Czechoslovak Air Force bought some few MiG-17PF from the USSR and got them into service. They also obtained a license to manufacture it locally under the designation of Aero S-104. We didn't find exact numbers of the production of the S-104, but they were manufactured at Aero Vodochody, in Prague, from 1956 until at least 1962 (if not later). They served until the very late 1970s when they were replaced by more modern types.
• East Germany: In 1956, with the creation of the Air Forces of the National People's Army, the MiG-17PF was supplied to the NVA (Nationale Volksarmee). It was, together with the regular MiG-17F the main bulk of the NVA fighter force. The PFs served alongside more advanced types like the MiG-19 until being replaced by more advanced types in the fighter role, namely the MiG-21 or the MiG-23.

Mikoyan-Gurevich MiG-17F, part six, various European users

The MiG-17F was the main fighter of many Warsaw Pact Users, among them, the following ones:

• Bulgaria: During the mid-to-late 1950s, the People's Republic of Bulgaria was supplied with batches of the newest Soviet jet fighters. The MiG-17F was active in the Bulgarian People's Army Air Force through the 1960s until the 1970s when it was withdrawn following a modernization period of the Bulgarian Air Force.
• Czechoslovakia: Some few MiG-17F served with the Czechoslovak Air Force before being locally produced as the Aero S-104. One of them was the personal aircraft of Gen. Jozef Kúkel who was the commander in chief of the 10th Air Army. Further details are unknown.
• East Germany: In 1956 the Soviet Union provided the newly established East German Air Force with many jet fighters and bombers, among them the MiG-17F. It served as their main interceptor/fighter until 1962 when the MiG-21 was introduced. After that, some of them were modified with added pylons to attach either bombs or rocket launchers. These modified machines were commonly known as the East German fighter-bomber and, while some of them were kept in active until the late 1980s, most of them were sold to African countries like Mozambique.

Mikoyan-Gurevich MiG-15UTI, part two, East German and Hungarian users

The Mikoyan MiG-15UTI was a Soviet trainer variant of the regular MiG-15. It had a modified cockpit to fit both instructor and student.
It was mass-manufactured and was the backbone of many air forces around the world, specially those in the Soviet sphere of influence and Warsaw Pact countries.
In this post we're going to cover just two countries: East Germany and Hungary.

• East Germany: In 1956 when the Luftstreitkräfte der Nationalen Volksarmee (Air Component of the National People's Army - East German Air Force) was created, they received a batch of MiG-15UTIs which was assigned to the Jagbombergeschwader JBG-31 among other fighter units. They served as their main jet trainer, together with other types like the Czechoslovak Aero L-29, from 1956 until the dissolution of the NVA (Nationale Volksarmee - National People's Army) in 1990. It was inherited by the West German Luftwaffe in that same year and, as it was already an obsolete type, most of them were scrapped or sold. One exemplar was repainted and sent to the Luftwaffe's Museum in Berlin where it's shown nowadays.
• Hungary: The Air Force of the Hungarian People's Army was completely modified in the 1950s to make it transition into the jet age as they were equipped with outdated propeller-fighters and bombers. As, in order to make the pilots meet the new jet fighters, they needed a trainer, the MiG-15UTI was supplied by the USSR. It served as the main trainer type until the fall of Eastern-bloc in the early 1990s, together with the Aero L-29 and, later the Aero L-39.

Mikoyan-Gurevich MiG-15bis, various European users

The Mikoyan-Gurevich MiG-15bis, which basically was an improved variant of the MiG-15, was introduced in 1950 and soon equipped the fighter force of many eastern bloc/Warsaw pact countries. Among those countries, there are the following:

• Bulgaria: After the end of the Korean war, where the MiG-15bis showed its capabilities, in 1955 the old propeller-driven Soviet-build fighters were replaced by MiG-15 and MiG-15bis entering the Bulgarian Air Force in the jet age, even if they had been already operating a very small number of Yakovlev Yak-17 fighters. They were gradually replaced by the MiG-17 during the next years.
• German Democratic Republic: When the Air Forces of the National People's Army was formed in 1956, they were initially equipped with the MiG-15bis which were replaced soon after with the introduction of the MiG-17F/PF and the MiG-15bis was soon relegated to advanced trainer duties.
• Hungarian People's Republic: Like other neighbouring countries of the eastern bloc or Warsaw Pact, until mid-1950s their Air Forces were equipped with World War II Soviet propeller aircrafts even if they received a small amount of Yakovlev Yak-23 as interim fighters. As that material had to be modernized, they received both MiG-15 and MiG-15bis which replaced every previous fighter type and were replaced by the more advanced MiG-17
• Socialist Republic of Romania: The Air Force of the Socialist Republic of Romania received their first jet aircrafts in 1951. They were an amount of Yakovlev Yak-17UTI trainers which were used to train pilots into the usage of jet aircraft. Soon after, in 1954, the Romanian Air Force received both the MiG-15 and MiG-15bis which replaced the old propeller-driven outdated fighters, which, in Romania, some of them were still Messerschmitt Bf.109G-6.
