SBIR Opportunity Analysis

The U.S. Space Force (USSF) is soliciting innovative solutions for space-based interceptors (SBIs) designed for boost-phase missile defense within the endo-atmospheric region, specifically below 120 km altitude. The initiative aims to develop compact, high-performance platforms that incorporate high-G propulsion systems, advanced sensor suites for target discrimination, and low-size, weight, and power (SWaP) interceptors to enable rapid and precise engagements. This effort is critical for establishing a layered missile defense architecture, emphasizing scalable designs and miniaturization suitable for deployment in distributed space-based platforms. Interested parties should note that this opportunity is a Direct-to-Phase II effort, with proposals due by April 29, 2026, and further details can be found at the provided source link: https://www.dodsbirsttr.mil/topics-app/.
