Recall that in August 2018, at the Army-2018 International Military-Technical Forum, the Ministry of Defense of the Russian Federation and PJSC Sukhoi Company signed a contract to supply the Armed Forces with the first two serial fifth-generation fighters Su-57 (in the guise of T- 50S - T-50S-1 and T-50S-2) with engines of the "first stage" ("product 117"). Terms of contract execution - 2018-2020, with delivery of one aircraft in 2019 and 2020. In June 2019 at the International military-technical forum "Army-2019" Ministry of Defense of the Russian Federation and PJSCfor the supply to the Armed Forces, a total of 76 fifth-generation serial fighters Su-57 (including the first two aircraft contracted in 2018). The deadline for the execution of the contract is 2027.
The first production aircraft Su-57 (aircraft T-50S-1, serial number 51001, tail number "01 blue"), built by KnAAZ, made its first flight in Komsomolsk-on-Amur in early December 2019 and was planned to be handed over to the Ministry of Defense On December 27, but on December 24, 2019, at the final stage of factory tests, it crashed as a result of an accident, due to, presumably, a failure in the aircraft control system.
The loss of the first production prototype of the Su-57 entailed major litigation at the personal level, including a change in the management of PJSC Sukhoi Company. According to available information, Sukhoi will be forced to compensate for the loss at its own expense by manufacturing another plane to replace the crashed one.
Now, flight tests have begun on the second of the two production prototypes of the Su-57 contracted in 2018. It should be transferred to the Russian Ministry of Defense by the end of the year.
