Air-to-air missiles are weapons designed to be launched from one aircraft to target another aircraft in flight. They are used primarily by military forces to gain air superiority and protect friendly aircraft from enemy threats. These missiles can be guided by various systems, including radar, infrared, or a combination of both, allowing them to track and engage fast-moving targets. These missiles come in different types, such as short-range missiles for close combat and beyond-visual-range missiles for long-distance engagements. Their effectiveness relies on advanced technology, including targeting systems and propulsion methods, ensuring they can hit their targets with precision and speed.
