Missile Detection Satellites
2014 – U.S. Missile Detection
There were two SBIRS GEO satellites and two SBIRS HEO payloads in operation by the end of 2014. These operated in concert with the older DSP satellites to fulfill all four missions. Two more SBIRS GEO satellites will be added to the SBIRS constellation, possibly around 2020. The USAF continues to pursue plans established in 1995 for integrating all OPIR satellite data, developing a new ground system and testing transmission of commands to multiple systems in March 2015.
2013 – U.S. Missile Detection
Satellites are essential tools for detecting hostile missiles being fired at allied forces. Systems such as the USAF Space-Based Infrared System (SBIRS)-High program are designed to monitor and give maximum warning of ballistic missile launches originating anywhere on the planet. The system consists of two HEO satellites, three Space Tracking and Surveillance System (STSS) spacecraft in LEO, as well as two GEO satellites, the most recent one being launched in March 2013.
2012 – U.S. Missile Detection
Some satellites are optimized to serve unique military functions. Missile launch detection satellites, such as the USAF Space-Based Infrared System (SBIRS)-High program, are designed to monitor and give maximum warning of ballistic missile launches originating anywhere on the planet. As of October 2012, there were two SBIRS-High payloads hosted on spacecraft in highly elliptical orbits. A third payload is planned for delivery to the USAF in 2013.

2005 – U.S. Missile Defense
Transportation-based activities also can be considered to include U.S. efforts at ballistic missile defense. The Missile Defense Agency (MDA) was established in 1999 “to deploy as soon as is technologically possible an effective National Missile Defense system capable of defending the territory of the United States against limited ballistic missile attack.” The MDA uses an integrated system of sensors and weapons to detect and destroy incoming ballistic missiles in their boost, midcourse, or terminal phase.
