The United Aircraft Corporation (UAC) has delivered to the Defense Ministry another batch of Su-35S fighter jets under the arms procurement order, Rostec said.

"The new fighter jets of generation 4++ have passed a full cycle of factory tests in various operational regimes and flew to the deployment airfield," it said.

Rostec first deputy CEO Vladimir Artyakov said Russian pilots praise the jets as the best in the class. They engage a broad range of weapons in all altitudes and speeds and fulfil the most difficult piloting and combat engagement techniques. "The fighter jets display the best flying qualities, excellent characteristics of navigational complexes and sights. The craft fulfil all missions and bring the victory closer," he said.

UAC CEO Vadim Badekha said the corporation works to keep the high pace of the production of fighter jets. "We plan to raise production effectiveness 30% by 2030. It will help produce major volumes under the arms procurement order that will exceed the high figures of last year," he said.
