United Launch Alliance launched a Lockheed Martin Atlas V 411 from Space Launch Complex 3-East at Vandenberg on Mar 13. The mission, which used vehicle AV-006, was a National Reconnaissance Office launch designated NROL-28 and placed a payload designated USA 200 in an elliptical 12-hour 63-degree inclination orbit.
Analysts believe that this launch is the second in a new series of satellites carrying combined signals intelligence and early warning payloads, and is similar to USA 184 (2006-027A/29249) launched in 2006 Jun.
USA 200 probably carried the SBIRS HEO-2 infrared missile early warning package and the NASA/Los Alamos TWINS-B magnetospheric research payload.
