Key Points and Ideas on the Su-57: Russia’s Su-57 “Felon,” conceived as the answer to America’s F-22 Raptor, has been a deeply troubled and largely unsuccessful fifth-generation fighter program.
-Plagued by persistent delays, particularly in developing its next-generation Izdeliye 30 engines, Russia has struggled to produce the jet in meaningful numbers, with fewer than 35 believed to be in service.
-The Su-57’s stealth capabilities are considered inferior to its US counterparts, and it has failed to secure a single confirmed export order.
-This production “nightmare” means Russia’s premier stealth fighter is a far cry from the world-beating aircraft the Kremlin promised.
Engine Failures and No Buyers: The Su-57 Is Russia’s Biggest Military Blunder
The Sukhoi Su-57 Felon is one of the most controversial fighters in use by the Russian Aerospace Forces. Depending on who you ask, the fighter is either one of the best or worst fighter jets produced in the last 20 years. The Su-57 was designed and built to address a specific strategic need and provide a credible deterrent against American fifth-generation fighters. Despite this, the Su-57 has faced immense challenges in production, which have severely limited the number of fighters Russia can field.
Origins of the Su-57
The conceptual foundation for the Su-57 began in the 1980s, when the Soviet Union initiated several advanced fighter programs to explore next-generation capabilities. Among these were the Mikoyan Project 1.44 and the Sukhoi S-37, later renamed the Su-47. These aircraft were experimental in nature, testing forward-swept wings, thrust vectoring, and other advanced aerodynamic features. However, the collapse of the Soviet Union in 1991 brought these efforts to a halt.
The economic turmoil of the 1990s forced Russia to shelve many ambitious defense projects, including its early attempts at developing a stealth fighter.
The PAK FA Project
By the early 2000s, the Russian government recognized the need to revive its advanced fighter program to maintain parity with Western air forces. This led to the launch of the PAK FA program, short for Perspektivny Aviatsionny Kompleks Frontovoy Aviatsii, or “Prospective Airborne Complex of Frontline Aviation.”
The goal of the PAK FA was to develop a fifth-generation multirole fighter that could perform air superiority, ground attack, and reconnaissance missions while incorporating stealth, supermaneuverability, and advanced avionics.
In 2002, the Russian Ministry of Defense selected the Sukhoi Design Bureau to lead the PAK FA project, choosing it over its traditional rival Mikoyan. Sukhoi had gained a reputation for producing highly capable fighters such as the Su-27 and Su-30, and its experience with the Su-47 experimental aircraft gave it a technological edge. The design that emerged from this effort would eventually become the Su-57.
Built to Counter the F-22
The Su-57 was envisioned as a multirole platform capable of engaging both air and ground targets with a high degree of survivability in contested environments. Its design incorporated stealth features such as internal weapons bays, radar-absorbent materials, and a reduced radar cross-section. However, unlike the American F-22, which prioritized stealth above all else, the Su-57 was designed to balance stealth with agility. This reflects a distinctly Russian design philosophy that values supermaneuverability and close-range dogfighting capabilities.
To achieve this, the Su-57 features a highly aerodynamic airframe, large control surfaces, and thrust-vectoring engines that allow it to perform extreme maneuvers. It also includes a sophisticated avionics suite, including the N036 Byelka active electronically scanned array (AESA) radar, infrared search and track (IRST) systems, and electronic warfare capabilities. These systems are designed to provide the pilot with a comprehensive picture of the battlespace through sensor fusion, a hallmark of fifth-generation fighters.
Development and First Flight
One of the most challenging aspects of the Su-57’s development has been its propulsion system. The aircraft initially flew with AL-41F1 engines, a modified version of the engines used in the Su-35. However, these engines do not meet the full performance requirements for a fifth-generation fighter. Russia has been developing a new engine, known as Izdeliye 30, which promises improved thrust, fuel efficiency, and stealth characteristics. As of 2025, the Izdeliye 30 is still undergoing testing, and full integration into the Su-57 fleet is expected in the coming years.
The Su-57 prototype, designated T-50, made its first flight on January 29, 2010, at the Komsomolsk-on-Amur Aircraft Plant. This marked a significant milestone in Russian aviation history, as it was the first stealth fighter developed by the country. Over the next decade, multiple prototypes were built and subjected to rigorous flight testing.
These tests evaluated the aircraft’s flight characteristics, weapons systems, radar performance, and overall reliability. However, the program faced numerous delays due to technical challenges, funding issues, and the complexity of integrating new technologies.
Finally Entering Production
The Su-57 entered limited serial production in 2020. The first production aircraft was delivered to the Russian Aerospace Forces (VKS) in December of that year, although it was technically a pre-production model. Fully operational Su-57s began entering service in 2021 and 2022, with Russia aiming to field 76 aircraft by 2028. However, this goal may be affected by economic constraints, international sanctions, and the ongoing need to refine the aircraft’s systems.
Russia has also sought to export the Su-57, marketing it as a cost-effective alternative to Western fifth-generation fighters. Countries such as Algeria, Vietnam, and Turkey have expressed interest, but no confirmed export deals have been finalized as of 2025. To enhance its export appeal, Russia unveiled a lighter, single-engine derivative of the Su-57 in 2021, known as the Su-75 “Checkmate.” This aircraft shares some design features with the Su-57 but is intended to be more affordable and modular, targeting countries that cannot afford more expensive platforms like the F-35.
Why the Su-57 Hasn’t Taken Off Yet
Despite its promise, the Su-57 has faced many criticisms, some warranted, some not. Some analysts argue that its stealth capabilities are inferior to those of the F-22 and F-35 due to design compromises. The slow pace of production has also limited its operational impact, and Russia’s economic situation has constrained its ability to scale up manufacturing. Additionally, some of the aircraft’s avionics and engine technologies are considered to lag behind their Western counterparts.
Many of the production bottlenecks seem to stem from the engines. The engines on the Su-57 have been tinkered with on multiple occasions, with the designers seemingly never satisfied with the results. Currently, Russia is testing the Su-57 with its new engine, and new serrated thrust vectoring nozzles. The result of these constant changes, however, is that production of the Su-57 has slowed to a crawl. Despite efforts to expand production, Russia still has less than 35 fifth-generation fighters by most estimates and production has not substantially increased. With its current rate, by the time it is built in large enough numbers, the Su-57 may be obsolete.

Please get a military aviation expert at the very least to post a bias article. Sounds like a five year old wrote this article. If you want to push a western bias propaganda article. Make sure he at least made a paper airplane in his lifetime
