The pilot of Russia's newest Su-57 fighter survived after the aircraft crashed during a test flight Tuesday in the far eastern Khabarovsk region, the Russian Defense Ministry said.

"The ejection system worked normally, so the pilot survived," the ministry's Zvezda broadcasting service quoted a spokesman for the United Aircraft Corporation, the producer of the aircraft, as saying.

The accident caused no victims or damage and a commission is investigating the cause of the crash, he said.

According to the Zvezda report, the aircraft has not yet been transferred to the Russian Aerospace Force.

The fifth-generation stealth Su-57 fighter, formerly known as T-50, is a single-seat twin-engine jet featuring super maneuverability and supersonic flight capability. Russia started the mass production of Su-57 earlier this year.
