Space-Based Infrared System (SBIRS)

The SBIRS program delivers timely, reliable and accurate missile warning and infrared surveillance information to key decision makers. The system enhances global missile launch detection capability, supports the nation's ballistic missile defense system, expands the country’s technical intelligence gathering capacity and bolsters situational awareness for warfighters on the battlefield. The SBIRS architecture includes a resilient mix of satellites in geosynchronous earth orbit (GEO), hosted payloads in HEO orbit, and ground hardware and software. The integrated system supports multiple missions simultaneously, while providing robust performance with global, persistent coverage.
