Su-57 destroyed in engine fire at Akhtubinsk airfield in Russia, HUR confirms

Ukraine's military intelligence reported that a Russian Su-57 fighter jet was damaged by an engine fire at Akhtubinsk airfield on October 29. The fire may be linked to poor jet fuel quality due to Ukrainian drone strikes on Russian oil refineries. Russia's reliance on imported aviation fuel has increased as domestic production has been disrupted. The Su-57, Russia's most advanced fighter jet, is valued between $35 million and $150 million. Despite its capabilities, the aircraft has had limited deployment in the Ukraine conflict and faced setbacks, including drone strikes and incidents of friendly fire.
