The Sukhoi Su-57, Russia’s fifth-generation stealth fighter, has a solid thrust-to-weight (P/W) ratio, especially with the new Izdeliye 30 engines, which are expected to replace the Saturn AL-41F1 engines currently used in production models. Here's a breakdown of the estimated P/W ratios for the Su-57 with each engine:

Su-57 P/W Ratio

With AL-41F1 Engines (Current)

• Engines: 2 × AL-41F1 engines (each producing ~88.3 kN dry, 142 kN with afterburner)

• Total Max Thrust (with afterburner): ~284 kN

• Empty Weight: ~18,000 kg

• Combat Weight: ~25,000 kg

• P/W Ratio: ~1.14 (with afterburner at combat weight)

With Izdeliye 30 Engines (Future, Expected)

• Engines: 2 × Izdeliye 30 engines (each producing ~110-117 kN dry, ~176 kN with afterburner)

• Total Max Thrust (with afterburner): ~352 kN

• Empty Weight: ~18,000 kg (same as above)

• Combat Weight: ~25,000 kg

• P/W Ratio: ~1.4 (with afterburner at combat weight)

Summary

• With AL-41F1 Engines: ~1.14 (combat weight, afterburner)

• With Izdeliye 30 Engines: ~1.4 (combat weight, afterburner)
