Space and Missile Systems Center
The Space and Missile Systems Center, a subordinate unit of U.S. Space Force, is the center of technical excellence for developing, acquiring, fielding and sustaining military space systems. SMC's mission is to deliver resilient and affordable space capabilities. The center is responsible for on-orbit check-out, testing, sustainment and maintenance of military satellite constellations and other Department of Defense space systems.
Space Based Infrared System
The Space Based Infrared System (SBIRS) program is the follow-on capability to the highly successful Defense Support Program. The SBIRS program was designed to provide a seamless operational transition from DSP to SBIRS and meet jointly-defined requirements of the defense and intelligence communities in support of the missile early warning, missile defense, battlespace awareness and technical intelligence mission areas.
Space Based Space Surveillance
The Space Based Space Surveillance (SBSS) operates 24-hours a day, 7-days a week collecting metric and Space Object Identification data for man-made orbiting objects without the disruption of weather, time of day and atmosphere that can limit ground-based systems. SBSS has a clear and unobstructed view of resident space objects orbiting earth from its 390-mile altitude orbit.
Space Rapid Capabilities Office
The Space Rapid Capabilities Office (Space RCO), a direct reporting unit of the U.S. Space Force, has a specialized, restricted and unique mission. Space RCO was created in response to the National Defense Strategy calling for improvements to defense acquisition. Space RCO was established via the FY18 National Defense Authorization Act (NDAA), with subsequent authorities defined in the FY19 NDAA.
