Space-Based Infrared System (SBIRS) is primarily used for which function?

Space-Based Infrared System is designed to detect the heat signatures of missile launches, turning infrared observations from space into timely warning of potential ballistic missile events. The infrared sensors on SBIRS can spot rocket plumes in the boost phase, around the globe and in all weather, providing rapid notices to national command authorities and forces to cue defenses and responses. This heat-detection role is what makes SBIRS the primary source for missile warning. GPS, meteorology, and protected SATCOM serve different purposes: GPS provides positioning and timing, weather satellites monitor atmospheric conditions and storms, and protected SATCOM carries secure communications. SBIRS isn’t used for navigation, weather forecasting, or communications, so its core function is missile warning.
