Interceptor missiles are designed to detect and destroy incoming threats, such as ballistic missiles or enemy aircraft, before they reach their targets. These missiles are part of a broader defense system that includes radar and command centers to track and engage threats effectively. When an incoming missile is detected, interceptor missiles are launched to intercept and neutralize it in the air. This process helps protect critical infrastructure and civilian populations from potential attacks, enhancing national security. Systems like the Aegis Ballistic Missile Defense and THAAD are examples of interceptor missile technologies used by various countries.
