Stealth capabilities refer to the technologies and techniques used to make objects, particularly military vehicles like aircraft and ships, less detectable by radar, infrared, and other detection methods. This is achieved through special shapes, materials, and coatings that minimize the reflection of radar waves and reduce heat signatures. These capabilities are crucial for modern warfare, allowing forces to operate with greater surprise and effectiveness. For example, the F-22 Raptor and B-2 Spirit are advanced fighter jets designed with stealth features, enabling them to evade enemy detection and carry out missions with reduced risk.
