The U.S. Space Force (USSF) is seeking innovative solutions to advance the development of space-based interceptors (SBIs) capable of conducting boost-phase missile defense within the endo-atmospheric region (below 120 km altitude). This effort aims to close critical capability gaps in early intercept technologies by maturing compact, high-performance platforms that enable rapid, precise, and survivable endo-atmospheric engagements from space-based assets.
The desired outcome is to develop and integrate high-G propulsion systems, advanced seekers, and low-SWaP interceptors integrated into space vehicles for an SBI architectures that support fast detection-to-intercept timelines. Emphasis is placed on scalable designs, manufacturability, miniaturization, and end-to-end system
integration suitable for future demonstrations on distributed space-based platforms.
This initiative supports the Space Force’s broader strategy to establish a layered missile defense architecture, leveraging space as a vantage point for intercepting evolving missile threats during their most vulnerable phase of flight. Technologies developed under this topic are expected to contribute directly to national security priorities
and long-term deterrence capabilities.
