Kinetic Energy Interceptors (KEI)
Northrop Grumman leads a team of the nation’s leading defense companies in developing and testing Kinetic Energy Interceptors (KEI).
KEI is the Ballistic Missile Defense System (BMDS) element that is being designed to destroy enemy ballistic missiles during their boost and early midcourse phases of flight. It is also the first ballistic missile defense weapon system to be developed without the constraints of the Anti-Ballistic Missile Treaty.
The KEI consists of a mobile launcher, an interceptor and a command and control battle management and communication (C2BMC) system that is housed in a transportable trailer. It is deployable anywhere in the world using U.S. military aircraft. Initially a land-based defensive capability, KEI is being designed for easy transition to sea-based platforms.
KEI will be integrated into the U.S. BMDS and will complement its other elements. Its visible, rapidly deployable design make it an effective deterrent.
KEI’s spectrum of capabilities matches a key objective of missile defense: to engage early and often in defense of the United States and its alliance.
