MOSCOW, — The Russian Aerospace Forces have received a new batch of Su-57 fifth-generation multirole fighter jets in an updated technical configuration, according to the United Aircraft Corporation (UAC), part of the Rostec state corporation.
The latest Su-57s feature changes to their armament and onboard systems, including expanded capabilities to employ newly developed air-to-air weapons. A Su-57 pilot involved in the acceptance process said the updated configuration expands the range of missions the aircraft can perform.
According to Rostec, the Su-57 has undergone significant development compared with earlier aircraft, with changes based in part on operational experience from the ongoing special military operation. Earlier upgrades have included modifications to onboard systems such as the electro-optical complex and expanded weapons integration options.
Before delivery, the newly built aircraft completed a full cycle of factory testing. Russian Ministry of Defense pilots then evaluated the fighters in different operating modes. After completing the tests and acceptance process, the aircraft flew to their assigned home airfields.
The Su-57 is designed as a multirole frontline aircraft capable of engaging air, ground and sea targets. It is intended for around-the-clock operations, including in adverse weather and electronic warfare environments.
The September delivery is the second announced delivery of Su-57s in the new technical configuration in 2026, following an earlier batch delivered in February. Rostec did not disclose the exact number of aircraft included in the latest batch.
UAC CEO Vadim Badekha said fulfilling the state defense order for Su-57s and other operational-tactical aircraft remains a priority. He added that UAC specialists, together with other Rostec companies, are continuing to improve production processes to maintain the required aircraft production rates.
The Su-57 program continues to receive upgrades to its avionics, sensors and weapons, while UAC is also conducting development work on the Izdeliye 177 fifth-generation engine. The aircraft first flew in 2010 and entered service with the Russian Aerospace Forces in 2020.
