Surface-to-Air Missile Systems (SAMs) are military weapons designed to target and destroy enemy aircraft. They are typically launched from the ground and can engage various aerial threats, including fighter jets and drones. SAMs use radar and guidance systems to track and intercept their targets, ensuring effective defense against aerial attacks. These systems vary in range and capability, from short-range missiles that protect specific areas to long-range systems that can engage targets at great distances. Notable examples include the Patriot missile system and the S-400, which are used by various countries to enhance their air defense capabilities.
