Russia's Su-57 Stealth Fighter Crashes During Factory Test Flight

Tass News is reporting that Russia's most advanced stealth fighter crashed Tuesday during a test flight in the Khabarovsk Region in the Far East of the country. 

The fifth-generation Su-57 fighter jet experienced technical failure of the aircraft's control system, a defense source told Tass.

"According to the preliminary information, the crash is due to a failure of the Su-57's control system," one of the sources said.

Another source said, "the tail control failed."

At the time of the incident, a civilian pilot was operating the Su-57, ejected from the aircraft 69 miles from the airfield. 

Russia's United Aircraft Corporation (UAC) also confirmed the crash on Tuesday.

The company said the Su-57's emergency system performed well and ejected the pilot to safety. 

TASS noted that this is the first crash of the Su-57, a fifth-generation multirole fighter that is designed to rival the US' Lockheed Martin F-22 Raptor and Lockheed Martin F-35 Lightning II stealth fighters.

The Su-57 was first tested in early 2010 and has since flown combat missions in Syria. 

Last month, UAC started series production of the Su-57, rolled off the first production jet, and delivered it to Russia's Aerospace Force.

Russia's Aerospace Force is expecting to receive 76 Su-57s by 2028. 

Back in August, Deputy Defense Minister Alexei Krivoruchko told the press that Su-57 is "the most advanced fifth-generation multirole fighter jet, which will boost the domestic Aerospace Force's combat capabilities" across the country. 

Russia is planning on arming the stealth jets with hypersonic missiles to become the deadliest planes in the world.
