by Vetri Suriya
The Sukhoi Su-57 (NATO name: Felon) is Russia’s first stealth multi-role fighter—designed to counter Western fifth-gen platforms like the F‑22 and F‑35.
🇷🇺 At a Glance

🔥 Strengths
- 3D thrust vectoring: unmatched agility
- Supercruise capability (future versions with Izdeliye 30 engines)
- Internal weapons bay for stealth ops
- AI integration with UCAV (e.g. Okhotnik-B drone teaming)
🚧 Limitations (as of 2025)
- Low production numbers (only ~20 in service)
- Maintenance & reliability concerns
- Radar cross-section larger than Western 5th-gen fighters
- Delays in second-generation engines
🌏 Global Relevance
India was initially part of the FGFA (Fifth Generation Fighter Aircraft) program based on the Su‑57 but later exited. Today, Russia offers Su‑57E for export to friendly nations.
Summary
The Su‑57 is an evolving platform. While not yet equal to the F‑35 in stealth or networked warfare, it dominates in raw kinematics and close-in dogfighting.
