SU-57 Felon Stealth Fighter: Russia’s Fifth-Generation Stealth Fighter

Developed by Sukhoi, the Su-57 Felon is Russia’s first operational fifth-generation stealth fighter, designed to rival the U.S. F-22 Raptor and F-35 Lightning II. Conceived under the PAK FA program, the Su-57 was built to provide the Russian Aerospace Forces with a multi-role platform capable of dominating both air-to-air and air-to-ground engagements while evading modern air defenses.

The Su-57 features a stealth-optimized airframe, internal weapons bays, and supermaneuverable thrust-vectoring engines. Constructed primarily from radar-absorbing composite materials, it integrates advanced avionics, sensor fusion, and artificial intelligence for target tracking and combat automation. Its N036 Byelka AESA radar offers 360° situational awareness with a detection range exceeding 400 km.

Powered by two AL-41F1 engines (to be replaced by the “Izdeliye 30” powerplant), the Su-57 achieves speeds of Mach 2 with supercruise capability. The fighter can deploy a wide range of armaments, including R-77 and R-74M air-to-air missiles, Kh-38 and Kh-59 strike missiles, and precision-guided bombs. Its internal bay and external pylons provide a 10,000 kg payload capacity.

Operational since 2020, the Su-57 has reportedly seen limited combat deployment in Ukraine, providing early data on its battlefield performance. Despite challenges in production and engine development, the Su-57 represents Russia’s most advanced attempt to establish parity with Western stealth aircraft, emphasizing maneuverability and versatility over pure stealth.

Special Export Versions

Variant	Description
Su-57E (Export)	First international version of the Su-57, tailored for export with downgraded electronics and restricted weapons suite. Announced at MAKS 2019, the Su-57E retains stealth shaping, thrust-vectoring engines, and multirole combat capability while meeting international arms export regulations.
Potential Export Partners	Nations such as India, Algeria, Vietnam, and China have shown varying degrees of interest in the Su-57E. However, no confirmed export orders have been signed as of 2025.
Customization Options	Russia’s United Aircraft Corporation (UAC) has proposed modular configurations to suit customer requirements, including localized avionics, weapons integration, and support infrastructure.
Export Restrictions	Export of the full-spec Su-57 remains restricted under Russian defense export controls. The Su-57E offers a balanced version with advanced capabilities while safeguarding sensitive technologies.
