The United Aircraft Corporation (UAC) delivered to the Russian Aerospace Forces a batch of Su-57 and Su-35S fighter jets. UAC CEO Vadim Badekha said there would be other batches this year.

The fighter jets have passed the whole cycle of factory trials and were accepted. Military pilots tested them at various operational regimes, Rostec said adding the fighter jets flew to the deployment airfield.

"UAC enterprises continue rhythmical operation to fulfil the commitments. Other batches of Su-57 fifth-generation and Su-35S multirole fighter jets of generation 4++ will be delivered by the end of the year. The aircraft are at various production and test stages," Badekha said.

Intellectual solutions in Su-57 provide excellent flight and combat characteristics, he said adding Su-57 is the best aircraft in its class.
