The U.S. Navy and Lockheed Martin delivered Sunday the fourth Mobile User Objective System satellite to the Cape Canaveral Air Force Station for launch in August.

The new Mobile User Objective System satellite, or MUOS, is a part of a network of orbiting satellites from Lockheed Martin and relay ground stations for secure communications for mobile military forces, providing seamless connections and smart phone-like capabilities. Among them are voice, video and mission data transmission on a high-speed Internet Protocol-based system.

"MUOS allows troops all over the world to talk, text and share mission data seamlessly while traveling, like a cellular network, without having to worry about where they are in relation to a satellite," said Iris Bombelyn, Lockheed Martin's vice president for narrowband communications. "MUOS-4 will complete our near global coverage, reaching further north and south toward the poles than ever before."

The MUOS network is expected to be operational by the end of this year.
