Kinetic Energy Interceptor (KEI)

The Kinetic Energy Interceptor (KEI) is a type of missile designed to destroy incoming ballistic missiles during their flight. It uses a "hit-to-kill" approach, meaning it aims to collide directly with the target to neutralize it, relying on the high speed of both the interceptor and the threat. This system is part of missile defense strategies, intended to protect against potential missile attacks. KEI is notable for its mobility, as it can be launched from various platforms, allowing for rapid deployment where needed.
