In cutting-edge aerial warfare, the Su-57 Felon, Russia’s formidable stealth fighter jet, has emerged as a contender against the unparalleled dominance of the United States F-35 Lightning II and China’s J-20 Mighty Dragon. While each aircraft boasts advanced capabilities, the ongoing conflict in Ukraine has thrust the Su-57’s performance into the spotlight, sparking debates about its actual lethality compared to its counterparts.
Striking The Su-57 Felon: Ukraine’s Audacious Claim
Amidst the chaos of the ongoing conflict, Ukraine’s military made a bold assertion on June 10, claiming to have successfully destroyed one of Russia’s prized Su-57 stealth fighters. This strike, reportedly carried out nearly 600 kilometres (372 miles) behind the front lines at a military base in the Astrakhan region, sent shockwaves through the aviation community.
To substantiate their claim, Ukraine’s defence intelligence agency (GUR) released satellite images on its Telegram channel depicting the alleged strike. The photos appeared to show an undamaged Su-57 on June 7, but by June 8, evidence of a strike was visible, with craters and fire damage surrounding the aircraft.
Further reports suggest that a second Su-57 Felon might have also been damaged in the raid, adding to the gravity of the situation. Since the Su-57’s maiden flight in 2010, the Russian Air Force has acquired approximately two dozen of these cutting-edge jets.
The Felon’s Formidable Design: Challenging Air Superiority
The Su-57, known as the “Felon” by NATO, is a supersonic, twin-engine, fifth-generation stealth fighter jet designed to challenge the United States’ air superiority. With its advanced design, the Felon aims to compete with the F-35 Lightning II and the J-20 Mighty Dragon.
However, despite its impressive features, the Su-57 has faced criticism for failing to match the success of the F-35, which boasts superior stealth, computing, and sensor capabilities. The F-35 remains the benchmark for modern fighter jets, outshining the Su-57, the J-20, and even the formidable US F-22 Raptors.
Stealth Capabilities: Separating Fact from Fiction
Experts have often highlighted that Russian and Chinese stealth fighters must be on par with the US-made F-35s. They point out that these nations have a history of overstating their military capabilities, casting doubt on the effectiveness of their stealth technology.
A former US Naval Aviator, Adam Daymude, noted significant design and performance shortcomings in the Su-57 and J-20. While acknowledging advanced design elements such as twin engines and blended fuselages, he questioned their stealth capabilities.
According to Daymude, the Su-57 and J-20 possess some competent design features, but when evaluated against actual fifth-generation standards like the F-35, they need to catch up. He further highlighted the canards on the J-20 as a significant drawback for its radar cross-section (RCS), and the Su-57 exhibits similar issues.
Due to unresolved doubts about their stealth and overall performance capabilities, Daymude firmly concluded that these aircraft should be classified as generation 4.5 or 5 rather than actual fifth-generation fighters.
Su-57 Felon: A Formidable Force in Numbers and Capabilities
The F-35 is consider superior to the Su-57 for its stealth capabilities, widespread production, and popularity as a tactical airframe. In contrast to the limit numbers of the Su-57, the F-35 has been produce in large quantities and is highly sought after globally.
After 1,000 F-35s were construct for the US Air Force, Navy, Marine Corps, and overseas clients, several European and Asian nations bought the jet. In comparison, while the Chengdu J-20 Mighty Dragon has been produce in significant numbers, with over 200 units reportedly built by early 2023, these numbers still need to catch up to the F-35.
Computing Power: The Su-57 Felon Secret Weapon
The F-35’s high computational capacity is sometimes neglected in favour of its apparent features, yet it distinguishes it from competitors. Usually referred to as a “flying computer,” the F-35 fighter jet advanced performance is mainly due to its central computer system, which controls all aspects of the aircraft. General David Goldfein, former US Air Force Chief of Staff, once described the F-35 not as a traditional fighter but as “a computer that happens to fly.” This advanced computing technology enables many of the F-35’s missions and operations, particularly for precision targeting.
For instance, software upgrades have significantly improved the performance of air-to-air and air-to-ground weapons like the AIM-120 and AIM-9X through enhanced flight path and guidance technology. The F-35’s “open architecture” and interoperable IP Protocol standards facilitate continuous improvement through ongoing software upgrades and modernization efforts, enabling rapid integration of new technologies without requiring an overhaul of the jet’s computing infrastructure.
Nuclear Strike Capability: The F-35’s Ultimate Edge
The most significant advantage of the F-35 is its status as the world’s only fifth-generation fighter jet capable of carrying nuclear bombs, surpassing other warplanes like the F-22, J-20, and Su-57. This milestone was achieve after over a decade of rigorous development, leading to the certification of the F-35A Lightning II stealth fighters in October 2023 to deliver B61-12 nuclear gravity bombs.
In May 2024, the Netherlands became the first to declare its F-35 stealth fighters capable of the nuclear strike role. This capability provides the US Air Force with a significantly more survivable method to deliver its tactical nuclear gravity bombs. The F-35’s advanced stealth capabilities allow it to penetrate enemy airspace with a lower risk of detection and effective engagement by ground-based air defence missiles, enhancing its status as the most lethal fighter jet in the world.
The Su-57 Felon’s design and capabilities are excellent, but its future against the F-35 and J-20 needs to be clarified. If true, Ukraine’s military strike might highlight the vulnerabilities of even the most modern stealth jets. As the Ukraine crisis proceeds, the aviation world will examine these cutting-edge aircraft’s performance to determine their strengths and weaknesses. The Su-57 Felon may challenge the F-35 and J-20 or be limited to a supporting role in aerial combat.
