General Dynamics Receives $732 Million Contract for MUOS Ground System Sustainment

General Dynamics Mission Systems (GDMS) is awarded a contract, worth around $732 million, for ground system sustainment of the U.S. Navy’s Mobile User Objective System (MUOS).

MUOS is a narrowband military satellite communications (SATCOM) system that supports a worldwide, multiservice population of users, providing modern netcentric communications capabilities while supporting legacy terminals.

The cost-plus-award-fee and firm-fixed-price indefinite-delivery/ indefinite-quantity (IDIQ) contract was awarded by the Navy’s Naval Information Warfare Systems Command (NAVWARSYSCOM). Fiscal 2020-2029 weapons procurement (Navy); fiscal 2020-2029 research, development, test and evaluation (Navy); and fiscal 2020-2029 operation and maintenance (Navy) funding will be applied to task orders after the contract award. Contract funds will not expire at the end of the current fiscal year.

Work will be performed in Scottsdale, Arizona (94%); Wahiawa, Hawaii (2%); San Diego, California (1%); Niscemi, Italy (1%); Chesapeake, Virginia (1%); and Geraldton, Australia (1%). Work is expected to be completed by November 2029.

Mobile User Objective System (MUOS)

The Mobile User Objective Systems (MUOS) is the U.S. Defense Department’s next-generation narrowband military satellite communications system. It will replace the legacy UHF Follow-On (UFO) system.

The system will support a worldwide, multiservice population of Ultra High Frequency (UHF) (300 MHz to 3 GHz frequency range) band users, providing increased communications capabilities to smaller terminals while still supporting interoperability with legacy terminals. It is designed to support users that require mobility, high data rates and improved operational availability, and will provide greater than 10 times the system capacity of the current UHF constellation.

The MUOS network is sustained by an initial configuration of four orbiting satellites (MUOS 1-4), built by Lockheed Martin, and four relay ground stations, built by General Dynamics Mission Systems. An on-orbit spare, MUOS-5, will ensure the network is always available to support the U.S. and allied mobile forces, as well as actively supporting the legacy UHF system. Each MUOS satellite includes a legacy UHF payload, in addition to the new MUOS payload.

The four ground stations, each of which serves one of the four active satellites of the MUOS constellation will be located at: the Australian Defence Satellite Communications Station at Kojarena about 30 km east of Geraldton, Western Australia; Naval Radio Transmitter Facility (NRTF) Niscemi about 60 km from Naval Air Station Sigonella, Sicily, Italy; Naval SATCOM Facility, Northwest Chesapeake, Southeast Virginia; and the Naval Computer and Telecommunications Area Master Station Pacific, Hawaii.

The MUOS system recently completed a critical test and evaluation phase and was assessed as operationally effective, operationally suitable and cyber survivable.
