SAN DIEGO - U.S. Navy shipboard com-munications experts are asking Gen-eral Dynamics to provide AN/USC-61(C) maritime radios to enable Navy surface warships and submarines to communicate over high frequency (HF), ultra-high frequency (UHF) line of sight, UHF satellite communications (SATCOM), and very high frequency (VHF) radio bands.
General Dynamics is providing AN/USC-61(C) maritime radios, shown above, to enable Navy surface warships and submarines to communicate over HF, VHF, UHF, and SATCOM frequencies.
Space and Naval Warfare Systems Command (SPAWAR) officials in San Diego announced a $198.1 million contract to General Dynamics Mission Systems in Scottsdale, Ariz., to build AN/USC-61(C) digital modular radio (DMR) systems. The contract includes high-frequency distribution amplifier group components, spare parts, and engineering services for continued fielding and maintenance of the maritime radio communications system.
The AN/USC-61(C) maritime software-defined radio (SDR) has become standard for the U.S. military. The multi-channel DMR provides several different waveforms and multi-level information security for voice and data communications. The radio includes embedded type 1 encryption; embedded red/black baseband switching and routing; co-site performance; reduced manpower requirements; single point of control for HF/VHF/UHF/SATCOM radio communications; and built-in test.
Software-defined radio waveforms are computer programs that enable SDR-enable radios to operate on different frequency bands with different encryption and cybersecurity functions. The AN/USC-61(C) operates on Navy surface ships, submarines, and other military platforms using frequencies from 2 MHz to 2 GHz.
General Dynamics has certified the DMR to pass secure voice and data at multiple independent levels of security (MILS) over HF, VHF, UHF, and SATCOM channels, and to withstand the effects of electromagnetic interference and other harsh operating conditions. The DMR also is certified by the Joint Interoperability Test Command to be compliant with the U.S. government's MIL-STD-188-181B/182A/183A requirements for UHF SATCOM. The AN/USC-61(C) uses open-architecture standards.
This contract has a five-year ordering period, and one option that could bring its value to $208.9 million. General Dynamics will do the work in Scottsdale, Ariz., and should be finished by December 2022.
