Sukhoi Su-57E "Felon"

The Su-57 is Russia's first 5th-generation fighter — the claim is "stealth and supercruise", reality per Western analyses is mixed. RCS claim ~0.1–1 m² (comparable to the F-35 or worse), but imperfect stealth shaping (in particular the engine-inlet design and exhaust nozzles) and lack of F-35-class RAM coating mean the Su-57 in practice sits closer to a 4.75-generation jet. Two AL-41F1 turbofans (interim), eventually Izdeliye-30 in production. Limited series production (~10–12/year per Western estimates). Algeria is reported as the first export customer (2024–2025), with unconfirmed Iranian interest. Effective combat record limited to "stand-off launches" with Kh-69 and Kh-59MK2 from Russian airspace over Ukraine; no air-combat data publicly confirmed.
