The MiG-21PFM is a further developmental version of the MiG-21, being the successor to the PF version, produced between 1964 and 1968. The aircraft was equipped with a new KM-1 ejection seat, which necessitated a redesign of the cockpit canopy — instead of the single-piece, forward-opening canopy, a two-piece canopy with a fixed windscreen and a right-opening rear section appeared.
An enlarged vertical stabiliser and a new wing equipped with flaps with a boundary layer blowing system were introduced, improving take-off characteristics. A new weapons system was fitted, allowing attacks on ground targets with bombs, guided and unguided rockets. A GP-9 pod with a twin-barrel GSh-23 cannon could be carried under the fuselage. MiG-21PFM aircraft in the 94N variant were adapted for carrying nuclear weapons. In NATO code, the MiG-21 PFM was designated “Fishbed F.”
MiG-21 aircraft in the F-13, PF and PFM versions took part in the Vietnam War and the Arab-Israeli wars. Poland purchased 132 MiG-21PFM aircraft between 1966 and 1968. It was the most numerous version of the MiG-21 operated in Poland.
The specimen with serial number 94A4205 and side number ‘4205’ served from August 1966 with the 41st Fighter Aviation Regiment at Malbork. After withdrawal from service, it was transferred to the Military University of Technology in Warsaw, where it was used for educational purposes.
