👉 The C4-I (Counter Missile Interceptor) and C4-E (Enhanced Counter Missile) are two types of cruise missiles developed by the United States during the Cold War era, primarily for missile defense purposes. The C4-I is a shorter-range, shorter-course interceptor designed to engage and destroy ballistic missiles in mid-flight, typically within 150-200 kilometers of the target. The C4-E is an upgraded version with a longer range and improved guidance systems, capable of intercepting higher-flying targets. Both missiles utilize advanced radar and infrared sensors for tracking and targeting, and they are capable of carrying a payload of up to 1,000 kilograms. They were deployed in various locations around the world, including Europe and Asia, to provide a layered defense against potential missile threats.
