Why is corrosion considered a significant issue for stealth aircraft?

Corrosion is regarded as a significant issue for stealth aircraft primarily because it can conceal the initial stages of damage. Stealth technology relies heavily on specific surface treatments and sophisticated materials designed to minimize radar cross-section. When corrosion occurs, it may develop beneath the surface or beneath coatings without being immediately visible. This progression can hinder the early detection of structural integrity issues. Consequently, any unseen degradation can lead to more severe damage over time, potentially compromising the aircraft's stealth capabilities and overall performance.

In no way can corrosion be classified as a factor that directly increases weight in a manner that would be more significant than the need to maintain critical surfaces for stealth. While it can affect systems or possibly influence speed and agility indirectly, the primary concern remains its ability to mask damage that could escalate into serious safety and operational issues. Detecting and addressing corrosion promptly is crucial to preserving the operational readiness and stealth effectiveness of these aircraft.
