Next-stage engine for Su-57 fighter jet to be delivered in coming years

Russian Aviaton » Wednesday June 3, 2026 11:11 MSK

Russia’s fifth-generation Sukhoi Su-57 fighter jet will begin receiving the new Product 177 engine in the coming years, CEO of the United Aircraft Corporation (UAC, part of Rostec) Vadim Badekha said in an interview with TASS.

"Today, the Su-57 fully meets the requirements for a fifth-generation fighter. The next-stage engine is Product 177. We should talk about equipping the Su-57 fighter with it not as a step necessary for the Su-57, but rather as additional capabilities that we will receive. We believe this will happen in the coming years," Badekha noted.

According to him, the engine is undergoing trials; the first flight with it has already taken place and was successful. Badekha noted that replacing the engine will not require any modifications to the aircraft.

  Light combat Yak-130M
  The presentation of the Ya-130M aircraft took place at the international military-technical forum "Army-2024", which was held from August 12 to 14, 2024 at the Patriot Convention and Exhibition Center. It should be noted right away that this is not just the modernization of the Yak-130 aircraft, but the transformation of a combat training aircraft into a full-fledged light combat aircraft. In the information field, this event was marked by a number of brief reports from federal news agencies. But the project, like the Yak-130 aircraft with its unique flight characteristics, deserves a more detailed review, which we decided to do.
