According to the interlocutor of TASS, in the future, the rate of production of fifth-generation fighters will increase to 15 aircraft per year, which will allow until 2028 to fulfill the contract for 2019 fighters for the Aerospace Forces signed in 76.
For our part, we note that there is no official confirmation of this information, but if you remove the phrase "second stage engine" from this news, it takes on a very real form, given that earlier Interfax, referring to its source, announced the transfer the first serial Su-57 in the Aerospace Forces until the end of November.
According to previously published reports, the first production fighters should go to the troops with the first stage engine. The engine of the second stage, according to various sources, will begin to be installed on the Su-57 from 2023 or 2025, but not earlier. In this regard, questions arise about "informed sources", which allow themselves to be very contradictory statements.
