Surface-to-Air Missiles (SAMs) are weapons designed to target and destroy aircraft from the ground. They are launched from fixed or mobile platforms and can engage various aerial threats, including fighter jets and drones. SAM systems vary in range and complexity, with some capable of tracking multiple targets simultaneously. These missiles use guidance systems, such as radar or infrared, to home in on their targets. SAMs play a crucial role in air defense strategies, protecting military installations and civilian areas from aerial attacks. Notable examples include the Patriot missile system and the S-400, which are used by various countries worldwide.
