Digital Modular Radio (DMR)

Software-Defined Communications For The U.S. Navy

The AN/USC-61 (C) Digital Modular Radio (DMR) is the first software defined radio to become a communications system standard for the U.S. Military. The DMR provides multiple waveforms and multi-level information security for voice and data communications. The DMR is currently deployed on 12 different U.S. Navy ship and submarine platforms.

  • Four full-duplex channels
  • HF, VHF, UHF, SATCOM and MUOS waveform capability
  • Programmable Type 1 MILS certification
  • Full qualification for U.S. Navy shipboard environment and Coalition Interoperable
  • VIDEO: Expanding the boundaries with the DMR

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. 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 in the U.S. Fleet and five eye countries. DMR is certified by the Joint Interoperability Test Command (JITC) to be compliant with the U.S. government’s MIL-STD-188- 181B/182A/183A requirements for UHF SATCOM.

Next-Generation Communications Capability

Built using open architecture standards, General Dynamics’ Digital Modular Radios continue to provide improved functionality and interoperability while setting the stage to incorporate next-generation communications, including forthcoming waveforms and advanced network connectivity, such as the Integrated Waveform and advanced network connectivity with the Mobile User Objective System (MUOS) waveforms.

  • Single radio for the entire 2 MHz – 2 GHz band
    • Lower spares cost and inventory
    • Single depot and common logistic
    • Common operations and maintenance training
    • Common manuals
    • Single point of control
    • Low life-cycle costs
  • Dramatically simplified shipboard communications system architecture
    • Embedded Type 1 Encryption
    • Embedded red/black baseband switching and routing
  • Superior co-site performance
  • Reduced manpower requirements
    • 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
