Russia may have produced a new batch of fifth-generation Su-57 fighters

The Russian Aerospace Forces may have received new fifth-generation Su-57 multi-role fighters.
Here's What We Know
The images show two wings with numbers 25 Red (RF-81796) and 26 Red (RF-81797). The images were probably taken on the territory of the Novosibirsk Chkalov Aviation Plant, the facility where these aircraft are mass-produced.
Nevertheless, neither the Russian United Aircraft Corporation nor the Russian Ministry of Defence has made any official statements regarding the new transfer of fighter jets. Thus, it is possible that the spotted aircraft could be part of a new batch or unreported copies from previous deliveries.

It is worth explaining that in November and December 2024, Russian media reported the transfer of at least one Su-57 to the Aerospace Forces, but only one flight was reported.
It is also worth mentioning that in December 2024, it became known that a Su-57 prototype with a new flat nozzle had been tested. It was an aircraft with the number "052", but it has not yet been clarified whether these tests are being conducted for the main fighter platform or for other developments, including the S-70 Okhotnik strike UAV. The latter, despite plans, is still equipped with traditional round nozzles.
