At 1018 GMT on 2 September 2015, an Atlas V 551 operated by ULA (United Launch Alliance) successfully launched the MUOS 4 (Mobile User Objective System 4) military telecommunications satellite for the US Navy. The launch took place from the Cape Canaveral launch site in Florida after a two day weather induced delay. The 6,740kg spacecraft was built by Lockheed Martin using a special version of its A2100 bus design. MUOS is designed to operate in geosynchronous Earth orbit approximately 36000km in altitude at a 5 degree inclination relative to the equatorial plane. The MUOS system will consist of four operational satellites plus one in-orbit spare.
