The Lockheed-Martin corporation has released that the Mobile User Objective System (MUOS) will employ third-generation (3G) commercial cellular technology to provide improved and assured communications to US warfighters. This announcement was made public by Lockheed-Martin, as MUOS prime integrator, at MILCOM 2004 in Monterey, California.

MUOS is an advanced narrowband tactical satellite communications system that will replace the current Ultra High Frequency Follow-On (UFO) system beginning in 2010 following the first MUOS spacecraft launch. In addition, MUOS will be fully compatible with existing UFO system and associated legacy terminals. Military communications availability will be increased by leveraging proven 3G commercial cellular advancements, which represent significant improvement over previous networking technologies.

MUOS will rely upon the MUOS 3G Wideband Code Division Multiple Access (WCDMA) waveform and the Universal Mobile Telecommunications System (UMTS) infrastructure to transmit text, voice, video and multimedia to a wide range of platforms, including 'always-on' connection handheld terminals that will be significantly faster than previous systems. MUOS will integrate seamlessly with the future Joint Tactical Radio System (JTRS) making possible full exploitation of JTRS features as well.

Lockheed-Martin team is currently under a $2.1 billion contract for development and manufacturing of two satellites and associated ground control elements on behalf the US Navy Space and Naval Warfare Systems Command (SPAWAR). The contract could be as high as $3.26 billion executing all options on three additional spacecraft. Final assembly and test will occur at Lockheed-Martin Space Systems facilities in Sunnyvale, California.
