Lockheed Martin has been awarded a $92.9 million Navy contract modification for the Mobile User Objective System (MUOS) narrowband satellite system.

Under the revised contract, Lockheed Martin will provide “engineering services, interim logistics services, spares and associated material,” according to the Department of Defense contract announcement.

The MUOS system includes four ground stations, each featuring three 19-meter antennas, four satellites, and an on-orbit spare. The system is designed to stream text, images and video to mobile forces at rates 10 times faster than the legacy Ultra-High Frequency Follow-On satellites.

The contract work is scheduled to be completed by November 2020. The sole-source contract was awarded by Space and Naval Warfare Systems Command, San Diego.
