USA-241, also known as SBIRS-GEO 2, is an American military satellite and part of the Space-Based Infrared System. 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 ICBM 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.
