 The Navy's fourth mobile user objective system, or MUOS satellite, launched from Cape Canaveral Florida September 2nd. MUOS 4 is part of a five-piece system that will provide global network coverage for warfighters and combatant commanders. This network will allow the exchange of critical situation awareness and targeting information. Beyond the system's initial requirements, it will also extend communications further north and south toward the polar regions. MUOS is a very flexible system. It can be used by pretty much every COCOM for every mission anywhere around the world, particularly if it's tactical and mobile. Narrowband UHF-SATCOM has many, many uses. For example, it will be used for special operations forces. The Army will extend SATCOM to each and every soldier, and the Navy in particular uses UHF-SATCOM for submarine communications on patrol.
