These satellites were launched and operated by the National Reconnaissance Office with the participation of the United States Air Force. Two of the three launches from Cape Canaveral were successful. The satellites collect SIGINT from near-geosynchronous orbits. Their precise mission and capabilities are highly classified, but they are widely believed to be successors to the Vortex/Chalet satellites.
