General Dynamics wins contract for AN/USC-61(C) DMR systems

General Dynamics Mission Systems is being awarded a contract for the continued procurement, manufacturing, testing and delivery of AN/USC-61(C) digital modular radio (DMR) systems.

The contract also includes high frequency distribution amplifier group components, spares, and engineering services to support their continued fielding and maintenance plans.

DMR is a modular, software reprogrammable radio system with embedded cryptography that provides all radio frequency (RF) to-baseband and baseband-to-RF conversion functions required for line-of-sight (LOS), beyond LOS and satellite communications systems operating between 2.0 megahertz to 2.0 gigahertz.

The indefinite-delivery/indefinite-quantity contract, worth around $198 million, was awarded by the U.S. Space and Naval Warfare Systems Command (SPAWAR) located in San Diego, California. No funds will be obligated at the time of award.  Contract actions will be issued and funds obligated as individual delivery orders.

This contract has a five-year ordering period up to the contract award amount.  There is one option which, if exercised, would bring the cumulative value of the contract to around $209 million.

Work will be performed in Scottsdale, Arizona, and is expected to be completed by December 2022.

AN/USC-61 (C)

The AN/USC-61 (C) Digital Modular Radio (DMR) is the first software defined radio (SDR) 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.

  • 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

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.

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.
