It was launched on March 19, 2013 from Cape Canaveral, atop an Atlas V rocket. The SBIRS satellites are a replacement for the Defense Support Program early warning system. They are intended to detect ballistic missile launches, as well as various other events in the infrared spectrum, including nuclear explosions, aircraft flights, space object entries and reentries, wildfires and spacecraft launches. SBIRS-GEO 2 was manufactured by Lockheed Martin and is built upon the A2100M satellite bus. In October 2013, the satellite was incorporated into the United States early warning network.[2] References1. ^1 Spaceflight Now Mission Status Center 2. ^"Air Force welcomes new craft into early warning network", Spaceflight Now, 26 November 2013.
