Russian Fighter Jet Crashes Amid Reports of Low-Quality Imported Fuel

Ukrainian intelligence reported on Friday that a Russian SU-57 fighter jet suffered engine failure and crashed at the Akhtubinsk airfield in the Astrakhan region. The agency said the malfunction was likely caused by the use of jet fuel that does not meet required specifications, noting that poor-quality fuel can lead to catastrophic engine failures.

The incident involves Russia's most advanced fighter aircraft, valued at roughly $140 million, and the same fuel type is reportedly used in other Russian fighter jets and jet-powered drones such as the Geran-4 and Geran-5.

According to the intelligence release, Russia has been compelled to import jet fuel from countries including India, Egypt and South Korea after Ukrainian long-range attacks have damaged numerous Russian refineries. The International Energy Agency estimates that Ukraine has launched more than 300 strikes on Russian refineries this year, successfully hitting over two dozen facilities and temporarily reducing Russia's refining capacity.

In response to the refinery attacks, Russia has banned exports of aviation fuel, while domestic fuel shortages have led to longer queues at gas stations.

"One of the reasons why engines of this type can explode or suffer catastrophic failure is poor-quality fuel," the Ukrainian intelligence agency said in its statement.

President Trump has publicly criticized the Ukrainian strikes, attributing rising U.S. gasoline prices to them, although analysts note that the price increases are linked to other factors, including tensions with Iran.
