It was launched on January 20, 2018 from Cape Canaveral, atop an Atlas V rocket. OverviewThe 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 4 was manufactured by Lockheed Martin and is built upon the A2100M satellite bus. The Atlas V launch vehicle used for SBIRS-GEO 4 flew with a strap-on booster, a different configuration from the previous three SBIRS-GEO launches. This was done as part of a space debris mitigation effort, to allow the Centaur upper stage to preserve sufficient fuel for a deorbit burn.[2] The Air Force announced the satellite was operating as expected and had established initial communication with it.[2] References1. ^1 {{cite web |url=http://spaceflightnow.com/2018/01/20/u-s-military-satellite-launched-to-fortify-against-missile-attacks |title=U.S. military satellite launched to fortify against missile attacks |last1=Clark |first1=Stephan |date=20 January 2018 |website=Spaceflight Now |publisher= |access-date=20 January 2018}} 2. ^1 {{cite web |url=http://spacenews.com/air-force-missile-warning-command-center-makes-contact-with-new-sbirs-satellite |title=Air Force missile-warning command center makes contact with new SBIRS satellite |last1=Erwin |first1=Sandra |date=20 January 2018 |website=SpaceNews.com |publisher= |access-date=24 January 2018}} External links{{Portal|Spaceflight}}
