School versions of MiG-21 aircraft
A large copes of one-seater MiG-21 fighters forced the purchase of school versions by Poland. We purchased three school versions; MiG-21 U, MiG-21 US, MiG-21 UM. It should be remembered that the school versions of combat aircraft in CCCP have always been able to perform combat tasks, although to a very limited extent. This was mainly due to the need to maintain an adequate mass of the aircraft. So no radar sights were mounted on them. For the MiG-21 in the training and combat version, the pilots were placed in a tandem arrangement. The student always occupied the first cabin. In the second sat an instructor. The first copy of the MiG-21 U was delivered to Poland on May 18, 1965, that is when two combat versions were already armed; MiG-21 F-13, MiG-21 PF.
A large number of built fighters resulted in the need to provide the army with a two-seater version. The MiG-21 F-13 (type 74) aircraft served as its basis. The E-6 U (pupil) prototype made its first flight on October 17, 1960. The pilot was Ostapienko. The seats were arranged in tandem. The cover consists of a permanent windscreen with three windows and a fairing with two windows, opening to the right. The capacity of the fuel installation was 2,350 liters. The plane was deprived of the plot, but in the suspended container under the fuselage there was km. 12.7 mm, with 60 bullets. The tank can be mounted interchangeably with the fuel tank. The weight of suspended equipment decreased to 250 kg. The plane received an on-board telephone SPU-7 and a device imitating damages.
The aircraft in production was designated MiG-21 U (type 66, 66-400). It was built in Tbilisi for own needs in 1962-1966, and for export 1964-1968. A hybrid MiG-21 U (type 66, 66-600) was produced in Moscow with an enlarged vertical tail and a braking parachute at the base of the ballast.

Training and combat versions were imported for training purposes. First, they were versions of the MiG-21U (66-400) imported in May and June 1965. In total, 6 were purchased. One item went to 41 PLM in Malbork.
5 MiG-21 U (66-600) machines were purchased along with the MiG-21 PFM. The first of them went to armament on August 7, 1966. Withdrawal from service of the first 3 units took place in December 1989, and the last 2 units were withdrawn in February 1990.
In 1969, 10 PLM in Łask received its first two-seater version of the aircraft. MiG-21 U type 66-400 aircraft No. 161220 were handed over from PLM 26, which was accepted on November 7, 1969. Until 1980, 10 PLM adopted 5 more MiG-21 Us, including the MiG-21 U type 66-600.
The last two pieces were withdrawn in February 1990 and handed over to the museums in Kraków and Drzonów.
The MiG-21 US variant belongs to the second generation of MiG-21 aircraft. Training and combat version for airplanes with SPS flap installation. In addition to the installation and appropriate engine, the aircraft received a KM-1 U ejection chair in the first cabin, and the KM-1 I in the second cabin; opened periscope for the KKO-5 instructor; oversized hull tank. The total capacity of the fuel installation was 2,450 liters.
Airplanes were produced in Tbilisi, in 1966-1970 for the Red Army and for export.

MiG-21 US training and combat aircraft were purchased for training fighter pilots of the MiG-21 M version. The first aircraft began service on August 28, 1969. The last one was delivered on 7/25/1970. A total of 12 MiG-21 US aircraft were purchased. Two of these aircraft went to 41 PLM in Malbork. The aircraft received KM-1 U and KM-1 J. seats.
In 1989, in the 1st PLM in Minsk Mazowiecki, the operation of the MiG-21 U training and combat unit was terminated, which is why this regiment received six MiG-21 US training and combat units from 62 PLM Krzesiny.
During the MiG-21 US service, only one disaster occurred. The tragedy occurred in 62 PLM in Krzesiny. On June 7, 1977, in the crash of the MiG-21 US aircraft No. 4609 No. 09685146, pilots, colonels Antoni Babkiewicz and Romuald Rejewski died. At the crash site, in 2001, a commemorative boulder with a plaque and two crosses were placed.
For the needs of training pilots of the 3rd and 4th generation of MiG-21 fighters, the training and combat version of the MiG-21 UM type 69, E-6 UM was developed. These machines were produced in Tbilisi in 1971-1982. A total of 1,133 MiG-21 UM aircraft were built.

This is the last version of the training-combat aircraft purchased by Poland. The first planes arrived in Poland on July 26, 1971. The aircraft was delivered in two periods. In the years 1971-1975 and in the years 1980-1981. This second series was used to train pilots of the latest MiG-21 bis version purchased by Poland.
Polish MiG-21 UM aircraft type 69 are equipped with; the AP-155 autopilot instead of the KAP-2 used so far. Externally, the aircraft received 4 catches for armament and additional fuel tanks.
In 1971, the first two MiG-21 UM received 41 PLM from Malbork.
In the period from January 1980 to May 1981, a second batch of MiG-21 UM training and combat aircraft was brought to Poland. There were 34 copies. The aircraft went mainly to units that received MiG-21 bis for armament. They were also equipped with 11 PLM from Wrocław, from which they were also transferred to 62 PLM in Krzesiny.
In total, Poland purchased 54 MiG-21 UM machines.
The last documented flight on this type was recorded at 41 ELT in Malbork. It was made on December 19, 2003, on the MiG-21 UM aircraft No. 9323 No. 516999323. The pilots were; colonel pilot Eugeniusz Garbas (commander 22 Blot) and Lt. Col. pilgrim dr Jan Rajchel (commander 41 ELT). This last flight was also preceded by a flight MiG-21 UM for aerial weather recognition. It was made by Lt. Col. Jan Drąg and Major Dipl. pilot Robert Dziadczykowski.
During operation, four MiG-21 UM aircraft were lost in disasters, and 1 in failures.
