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. The compact, multi-channel DMR provides multiple waveforms and multi-level information security for voice and data communications from the core of the network to the tactical edge. The DMR is currently deployed on 12 different U.S. ship and submarine platforms. The DMR system approach reduces SWAP-C on platforms.

  • 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
  • Coalition Interoperable
  • 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.

DMR Today

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.

    • Single point of control for entire HF/VHF/UHF/SATCOM system
    • High reliability
    • Built-In Test (BIT)
  • Full logistical support in the U.S. Navy system
    • Single depot and common logistic
    • Common operations and maintenance training
    • Common manuals
    • Low life-cycle costs
    • Very low maintenance costs
  • FMS Approved
