Russia’s United Aircraft Corporation (UAC) has delivered a new batch of Su-35S fighter jets to the country’s Ministry of Defense, state corporation Rostec said.

The aircraft underwent testing in various operating modes before flying from Komsomolsk-on-Amur to their designated base, according to Rostec.

A Russian Aerospace Forces Su-35S pilot said the aircraft are actively used in combat operations, including intercepting airborne targets, providing cover for strike groups and ground facilities, and carrying out precision strikes against ground and surface targets.
