The destination airbase has also not been disclosed. Without a batch size or details of the new configuration, the announcement provides little basis for assessing the pace of deliveries or the extent of the equipment changes.
The Russian Defence Ministry has received about 50 production Su-57s, according to the source article. Russian officials say some have been used in combat operations over Ukraine.
A June 2019 order called for 76 production aircraft by 2028, a number intended to re-equip three fighter regiments. Russia’s official plan has envisaged output of 12 Su-57s a year from 2024, but the latest announcement gives no delivery figure against which to measure that rate.
