Russia’s Su-57: A Stealth Fighter Facing an Uphill Battle
Russia’s state industrial conglomerate, Rostec, continues to promote the capabilities of its fifth-generation multirole fighter, the Sukhoi Su-57 (NATO reporting name ‘Felon’). Recent announcements highlight the integration of new weapons systems into the stealth aircraft, aiming to enhance its effectiveness in diverse conditions and against electronic warfare attempts.
New Weapons, Extended Reach
According to statements from the Russian Ministry of Defence, pilots of the Russian Aerospace Forces have accepted Su-57s in a new technical configuration. While specific details of the upgraded weaponry remain undisclosed, Rostec emphasizes the improvements will allow the aircraft to operate more effectively in varied weather and electronic warfare environments. The Su-57 is equipped with a 30mm GSH-30-1 cannon, and can carry a range of air-to-air and air-to-surface missiles and guided bombs, including the R-77M and R-37M long-range air-to-air missiles, R-74M2 short-range missiles, and Kh-59MK2 cruise missiles.
The ‘Izdelie 177’ Engine: A Key Upgrade
Recent testing has focused on integrating the new ‘Izdelie 177’ engine, developed specifically for the Su-57. This engine is reported to provide up to 16,000 kg of thrust with afterburner, while also reducing fuel consumption and increasing durability compared to previous powerplants. This upgrade is crucial for enhancing the aircraft’s performance and operational range.
Limited Production and Global Competition
Despite the ongoing upgrades, production numbers remain low. Estimates suggest that approximately 32 Su-57s, including prototypes, are currently in service with the Russian Aerospace Forces as of 2026. This contrasts sharply with the United States, which operates 183 Lockheed Martin F-22 Raptors and over 1300 Lockheed Martin F-35 Lightning IIs, with continued production planned for decades to approach.
Rostec and Rosoboronexport are actively seeking foreign buyers for the Su-57, but success has been limited. Algeria is the only confirmed customer, and potential acquisitions face the risk of sanctions from the United States. The limited production and geopolitical concerns create significant hurdles for wider adoption.
Cost and Challenges in Serial Production
The Su-57, estimated to cost between $50 and $100 million per unit, is Russia’s most advanced and expensive fighter jet. However, serial production began in 2022, but deliveries have been hampered by supply chain issues and funding constraints. This makes it a less attractive option for countries that can procure established fifth-generation fighters from Western manufacturers.
The Future of Fifth-Generation Fighters: A Shifting Landscape
The Su-57’s struggles highlight broader trends in the fifth-generation fighter market. While Russia continues to invest in its domestic capabilities, the dominance of American manufacturers and the emergence of new players are reshaping the landscape.
The Rise of the F-35 and Beyond
The Lockheed Martin F-35 Lightning II has become the cornerstone of many air forces worldwide, offering a versatile platform for a wide range of missions. Continued development and upgrades to the F-35, alongside the F-22, ensure the United States maintains a significant technological advantage.
China’s J-20: A Growing Competitor
China’s J-20 stealth fighter is rapidly maturing and represents a significant challenge to Western air superiority. With increasing production rates and ongoing improvements, the J-20 is poised to become a major player in the global fighter market.
The Sixth Generation: Looking Ahead
Development of sixth-generation fighters is already underway in the United States, the United Kingdom, and other countries. These future aircraft will incorporate advanced technologies such as directed energy weapons, artificial intelligence, and enhanced sensor fusion, promising a new era of air combat capabilities.
