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.
