<h1>Space-based missile defence aims to deploy multilayered interceptors to detect and stop advanced missiles across all flight stages.</h1> A multilayered missile defence concept prioritises space-based interceptors and expanded satellite sensors alongside ground systems to detect and defeat missiles at pre-launch, boost, midcourse, and terminal phases. The administration selected the concept and assigned senior Space Force oversight while the Pentagon drafts an initial capabilities document to define operational requirements. Cost estimates for space-based components substantially exceed the initial funding request, and planners are developing medium, high, and extra-high acquisition options tied to the number and type of satellites, sensors, and interceptors to be procured.
