Digital Modular Radio (DMR)
Software-Defined Communications For The U.S. Navy
The Digital Modular Radio (DMR), AN/USC-61(C), is the first software defined radio to have become a communications system standard for the U.S. Military. As one of the Navy’s most versatile tactical radios, one four-channel DMR can simultaneously support voice and data satellite communication networks, Mobile User Objective System (MUOS) waveforms, Single Channel Ground and Airborne Radio Systems, HAVEQUICK, and other tactical, HF/VHF/UHF radios.
Four full-duplex channels
Complete VHF/UHF Line-of-Sight and HF/UHF Beyond Line-of-Sight waveform capability
Programmable Type 1 MILS certification on 4 channels
Full qualification for U.S. Navy and U.S. Coast Guard shipboard environments
Foreign Military Sales (FMS) Five Eye Approved

Next-Generation Communications at Sea
Built using open architecture standards, General Dynamics Digital Modular Radios continue to provide improved functionality and interoperability by including waveforms and advanced network connectivity, such as the Integrated Waveform and advanced network connectivity with the Mobile User Objective System (MUOS) waveforms.
Additionally, system-wide software applications such as Dynamic Routing and Virtual Channel Exploitation extend channel capacity without additional hardware.
Digital Modular Radios currently operate aboard U.S. Navy surface and subsurface vessels, fixed-sites and other Department of Defense communication platforms using frequencies ranging from 2 MHz to 2 GHz. The USCG will receive the DMR system in FY2019. Certified to pass secure voice and data at Multiple Independent Levels of Security (MILS) over HF, VHF, UHF, and SATCOM channels, the DMR system was developed to the U.S. Navy’s specifications and meets all the stringent environmental, EMI and performance requirements for use on U.S. Fleets and five eye countries. DMR is certified by the Joint Interoperability Test Command (JITC) to be compliant with the U.S. government’s UHF SATCOM.
