“ Aircraft with the engine of the second stage are now undergoing flight tests. Already under the current serial contract, it is planned to supply the Su-57 with a new engine – the UEC and UAC are working on this , ”said Vladimir Artyakov.
Serial production of the Su-57 fighter with new engines will begin before 2027.
He added that the Su-57 is adapted for the use of the engine of both the first and second stages. “ Even with the engine of the first stage, the fighter meets the basic requirements for a fifth-generation aircraft ,” said the first deputy head of Rostec.
Thus, mass production of the Su-57 with new engines will begin before 2027, since a contract was signed before this year. The new engine has a flat nozzle and a variable thrust vector. A number of its components will be printed on a 3D printer.
