The EELV program's Delta IV and Atlas V launch vehicles are produced by United Launch Alliance (a joint venture of Boeing and Lockheed Martin formed in 2006). A new EELV Acquisition Strategy was approved in November 2011 which recognizes only the Atlas V and Delta IV can currently provide reliable launch services to meet NSS requirements but also seeks to take advantage of the growing potential of additional commercial space launch providers.
