Fact check: Analysis of the SU-57 indicates that it lacks the characteristics of a true stealth fighter.

1. Summary of the results

1. Summary of the results:

The analyses confirm significant stealth limitations in the SU-57's design, including exposed engines, body panel gaps, and higher radar visibility compared to Western counterparts. Technical evidence shows it uses only 25% composite materials (versus F-22's 40%) and relies on radar-absorbent coatings rather than shape-based stealth design. Production has been limited to approximately 15 aircraft, with India withdrawing from joint development in 2018 due to concerns about stealth capabilities.

2. Missing context/alternative viewpoints:

The original statement omits that stealth exists on a spectrum - while the SU-57 may not match F-22 standards, it still offers better stealth characteristics than 4th generation fighters. The aircraft compensates for stealth limitations with other advanced features:

• 3D thrust vectoring capabilities
• Higher operational ceiling
• Larger weapons capacity
• Versatile combat capabilities

Russian military strategists may have intentionally prioritized these features over pure stealth capabilities, based on their different combat doctrine and operational needs.

3. Potential misinformation/bias in the original statement:

The statement presents a Western-centric view of what constitutes a "true stealth fighter," primarily comparing it to American standards (F-22 and F-35). This benefits Western defense contractors and NATO-aligned nations by diminishing Russian military capabilities in public perception. The term "true stealth fighter" lacks a standardized definition in military aviation. The statement also ignores that development limitations may be more related to economic sanctions and industrial constraints rather than technical expertise - the SU-57's compromises might reflect practical necessity rather than design philosophy.
