Anti-aircraft missiles are weapons designed to target and destroy enemy aircraft. They are launched from ground-based platforms or ships and can track and intercept planes, helicopters, and drones. These missiles use advanced technology, including radar and infrared guidance systems, to accurately hit fast-moving aerial targets. These systems are crucial for national defense, protecting airspace from potential threats. Countries often deploy anti-aircraft missiles as part of their military strategy, ensuring the safety of their air operations. Notable examples include the Patriot missile system and the S-400, which are used by various nations around the world.
