Officials say the launch services deal will deliver the Navy's first Mobile User Objective System, which will enable improved communications including simultaneous voice, video and data for U.S. forces in the field. Officials say the MUOS satellite will be aboard an Atlas V Evolved Expendable Launch Vehicle expected to launch in 2010 from the ULA complex at the Cape Canaveral Air Force Station, Fla.

The MUOS, a program managed by U.S. company Lockheed Martin Space Systems, will also improve service to the Navy's ultra high frequency follow-on system currently in orbit with next-generation narrowband tactical satellite communications.

"United Launch Alliance is proud to continue our long partnership with the Navy, which includes the successful launch of four UHF F/O satellites on Atlas within the last decade," Jim Sponnick, ULA vice president of Atlas programs, said in a statement. "Cost-effective assured access to space is our continuing commitment to the U.S. government, and we are looking forward to working with the Air Force, the Navy and Lockheed Martin Space Systems to launch this latest technology for the mobile warfighter."
