General Dynamics Mission Systems was awarded a contract that could be worth as much as $208 million to continue procuring digital modular radio systems for the Navy.

The indefinite-delivery, indefinite-quantity contract would allow the Navy to order high frequency distribution amplifier group components, spare parts and engineering services to support continued fielding and maintenance plans of the AN/USC-61 (C) system, according to a Dec. 13 announcement from the Department of Defense.

General Dynamics says the AN/USC-61 (C) is the first software-defined radio to become a communications standard for the military providing multiple waveforms and multilevel information security for voice and data communications.

The system 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 and is currently deployed on 12 different Navy ship and submarine platforms.

The contract covers a five-year ordering period. The work will be done under the purview of the Navy’s Space and Naval Warfare Systems Command.
