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.

Mikoyan-Gurevich MiG-15UTI, part ten, Polish versions.

The MiG-15UTI was locally built in many eastern-bloc countries such as Czechoslovakia or Poland. The Polish versions were one of the most used ones as they were used from the early 1950s until nowadays where they are still used in aerial shows.
The WSK-Mielec SBLim-1 was a Polish version of the MiG-15UTI made from converted old Lim-1 (or even Czechoslovak Aero S-102 -The Czechoslovak produced MiG-15bis) fighters. They were manufactured by Lotnicze Zaklady Remontowe Nr.2 at the Polish town of Bydgoszcz, close to Warsaw. The first converted exemplar was completed in 1957 and production lasted until 1966 with approximately 280 units converted. It was powered by the Lis-1 engine (a licensed version of the Klimov RD-45F engine) which delivered 5005lb (22,26kN) of thrust and was armed with a single 23mm (0.9in) NS-23 cannon or a single 12,7mm (0,5in) A-12.7 machine gun.
It served alongside the SBLim-2 until it was gradually replaced by either the SBLim-2 itself or the PZL TS-11 Iskra as the main Polish trainer aircraft.
The SBLim-2 was the next step as it was a MiG-15UTI made either from scratch or converted from obsolete Lim-2 fighters. It was also manufactured by Lotnicze Zaklady Remontowe Nr.2 at the town of Bydgoszcz. Production started in 1966 and continued well until the 1970s with around 200 of them converted and some of them even adapted for artillery spotting duties. It was powered by the Lis-2 engine which was a licensed version of the Klimov VK-1A and could deliver a power of 5952lb of thrust (26,48kN). It differed from the regular MiG-15UTI, apart from the better engine, in being better armed as it was armed both with the NS-23 cannon and the A-12.7 machine gun. They were used by the Polish Air Force until the fall of communism both in the trainer and artillery spotter role.
One SBLim-2 was bought in 1997 by a private owner in Argentina and flew again three years later in the year 2000. Nowadays is shown (repainted) at the Museo Nacional de Aeronáutica (National Museum of Aeronautics).
