The U.S. Navy has awarded General Dynamics Mission Systems a five year, $208 million indefinite delivery, indefinite quantity contract for the continued procurement, testing and delivery of the AN/USC-61(C) Digital Modular Radio.

The Digital Modular Radio (DMR) provides multiple communication waveforms and multi-level information security for secure tactical voice and data transmissions aboard U.S. Navy ships and submarines.

“With more than 700 DMR radios deployed across the U.S. Navy’s fleet, General Dynamics continues its commitment to provide the Navy with new and innovative radio technologies, developing next-generation communications that support the ever-evolving mission needs of sailors operating around the world,” said Paul Parent, a vice president of General Dynamics Mission Systems.

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 latest DMR improvement increases transmission rates while reducing static and other audio noise for crisp, clear voice communications.

The Mobile User Objective System (MUOS) waveform was added to DMR in 2012 to significantly enhance the Navy’s beyond line-of-site, or satellite voice and data communications by connecting to the MUOS satellite communications network.

Since the original contract award in 1998, the DMR has evolved from its initial offering of UHF SATCOM to provide a full spectrum of mission critical communications capabilities including:

  • MILSATCOM satellite network controller
  • Beyond line-of-sight High Frequency (HF) with Automated Link Establishment (ALE)
  • VHF Single-Channel Ground and Airborne Radio Systems (SINCGARS)
  • UHF HAVEQUICK, and other communication waveforms

The radios are also equipped with General Dynamics’ Advanced Infosec Machine (AIM) encryption chip, certified by NSA to handle classified information at the Type 1 – Top Secret level and below.

The radios also communicate simultaneously at multiple levels of security, on each of the radios four channels.

Next-Generation Communications Capability

General Dynamics Mission Systems logoBuilt 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 waveforms and advanced network connectivity, such as the Integrated Waveform and advanced network connectivity with the Mobile User Objective System (MUOS) waveforms.
