Stealth Technology Evolution

Stealth technology has evolved from the F-117 to the F-35, fundamentally changing how aircraft are designed.

Design Principles

1. Faceted Surfaces: Early stealth used flat, angled surfaces to deflect radar.
2. Curved Surfaces: Modern stealth uses advanced computational modeling for curved shapes.
3. Radar-Absorbent Materials: New composites that absorb radar energy.

The future of stealth lies in adaptive materials and active cancellation technologies.
