USA 241



Successful launch of Space-Based Infra Red System missile detection satellite for geosynchronous orbit. It carries a combination of scanning and staring sensors with greater sensitivity than previous satellite types. The scanning sensor will provide a wide area view in search of missile launches and natural terrestrial events, while the staring sensor will be used to observe areas of particular interest with enhanced sensitivity.

The vehicle is part of a developing satellite constellation. Two payloads were included on satellites in Molniya-type HEO with apogees above the northern hemisphere (USA 184 and USA 200). USA 230 (SBIRS GEO 1) was launched towards geosynchronous orbit 2011 May.
