Space-Based Interceptors for Boost-Phase Missile Defense in the Endo-Atmospheric Region
SBIR Opportunity Analysis
The U.S. Space Force (USSF) is soliciting innovative solutions for the development of space-based interceptors (SBIs) capable of conducting boost-phase missile defense within the endo-atmospheric region, specifically below 120 km altitude. The objective is to create compact, high-performance platforms that incorporate high-G propulsion systems, advanced sensor suites for reliable target discrimination, and low-size, weight, and power (SWaP) interceptors, all designed for rapid and precise engagements. This initiative is critical for establishing a layered missile defense architecture, emphasizing scalable designs and miniaturization suitable for deployment in distributed satellite constellations. Interested applicants must prepare Direct-to-Phase II proposals demonstrating prior feasibility, with the application due by April 1, 2026.
