United Launch Alliance (ULA) is a joint venture of Lockheed Martin Space Systems and Boeing Defense, Space & Security. ULA was formed in December 2006 by combining the teams at these companies which provide spacecraft launch services to the government of the United States. ULA launches from both coasts of the US. They launch their Atlas V vehicle from LC-41 in Cape Canaveral and LC-3E at Vandeberg. Their Delta IV launches from LC-37 at Cape Canaveral and LC-6 at Vandenberg.
Primary payload of the mission is the Continuous Broadcast Augmenting SATCOM (CBAS) satellite, which will be placed in geosynchronous orbit. It will continously relay data from from existing military communications satellites to support senior leaders and combatant commanders. This mission will also launch a number of secondary payloads hosted on the ESPA Augmented Geostationary Laboratory Experiment (EAGLE).
