Russia’s Defense Ministry will receive four Su-57 fifth-generation fighters this year, Russian Deputy Prime Minister Yuri Borisov said during his visit to the Gagarin Aviation Plant in Komsomolsk-on-Amur in Russia’s Far East on Wednesday.

"This year, 15 combat planes are due to be delivered [by the Gagarin Aviation Plant] to the customer and under export contracts. As you know, the Defense Ministry has signed a large long-term contract on the Su-57, and this year four serial-produced planes will be delivered. The production of generation 4++ Su-35 planes continues," the vice-premier said.
