Introduction: The Ghosts of the Sky Stealth aircraft, often dubbed "invisible planes," evoke images of futuristic warfare and covert missions. Yet, their ability to evade detection isn’t magic—it’s a meticulously engineered blend of science, geometry, and material innovation. From the angular F-117 Nighthawk to the sleek B-2 Spirit, stealth technology has revolutionized modern aviation. But how do these aircraft truly disappear from enemy radar—and what are their limitations? A high-tech digital illustration of a futuristic stealth aircraft flying at high altitude, utilizing advanced radar-evading design and next-generation stealth technology. The aircraft seamlessly blends into the night sky, showcasing innovations in aerodynamics, radar absorption, and infrared suppression. The Science of Radar Evasion: Deflecting the Enemy’s Eye At the core of stealth technology is the reduction of an aircraft’s  radar cross-section (RCS) —the detectable "size" of an ob...
