Aegis Ballistic Missile Defense (BMD) is a naval defense system designed to detect, track, and intercept short- to intermediate-range ballistic missiles. It utilizes advanced radar and missile technology, primarily deployed on Aegis-equipped ships, to provide a protective shield over land and sea. The system is part of a broader strategy to enhance national security and protect allies from missile threats. It integrates with other defense systems and can work in conjunction with land-based systems, contributing to a layered defense approach against potential missile attacks.
