Space-based missile defense systems

Space-based missile defense systems involve satellites equipped with sensors and interceptors that monitor, detect, and potentially destroy incoming ballistic missiles at various stages of flight, including in space or during reentry. These systems aim to provide early warning and layered defense coverage over large areas, improving response time and treaty compliance. While technically complex and costly, space-based missile defense enhances national security by extending the horizon of detection beyond ground or sea-based systems, offering a strategic advantage in preventing missile attacks.
