Ukraine’s military intelligence agency (HUR) has identified more than 100 enterprises involved in the production of Russia’s Su-57 fighter jets. According to the statement, among the companies listed are several key contributors to the aircraft’s development and manufacturing.

The identified entities include the St. Petersburg-based “Krasny Oktyabr,” which manufactures auxiliary power units, specifically gas turbine engines used in the Su-57, as well as the National Institute of Aviation Technologies, which contributes to the development of the aircraft’s multifunctional cockpit glazing.
Also involved is the Institute of Theoretical and Applied Electrodynamics of the Russian Academy of Sciences, responsible for developing and applying radar-absorbing coatings to aircraft components.
Another identified company, YASHV Avia LLC, manufactures aviation tires for the Su-57 fighter jets.
“A third of these enterprises are still not subject to restrictions by any country in the sanctions coalition, allowing them to maintain access to foreign technologies and component bases necessary for the development of Russia’s military aviation,” HUR reported.
What is Su-57?
The Sukhoi Su-57 is Russia’s first operational fifth-generation, twin-engine multirole stealth fighter, developed by Sukhoi. It is designed for both air superiority and strike missions, combining high maneuverability, supersonic cruising capability, and advanced avionics.
As a fifth-generation aircraft—by Russia’s classification—the Su-57 is expected to meet a number of advanced performance criteria. These include highly efficient engines and the ability to maintain supersonic flight without using afterburners. It is also designed to reach speeds of at least Mach 2, demonstrate a high degree of maneuverability, and significantly reduce its visibility across radar and infrared spectrums.
This reduced detectability is achieved through stealth technologies, including modifications to the aircraft’s shape and engine nozzles, as well as the use of radio-transparent composite materials and radar-absorbing coatings. In addition, onboard systems are designed to rely more on passive detection methods and operate in low-observable modes to enhance survivability.

At the same time, the US administration is weighing the possibility of imposing sanctions on Algeria over its reported purchase of Russian fighter jets.
The statement was made by Robert Palladino, head of the US State Department’s Bureau of Near Eastern Affairs, during a Senate Foreign Relations Committee hearing on February 3, according to Russia’s state-run news agency TASS.
“We are aware of media reports regarding this matter, and we find them concerning,” Palladino said in response to a question from lawmakers about potential sanctions. “We will continue to monitor the situation closely,” he added, noting that further discussions would take place with senators in a closed session.
