General Dynamics Mission Systems secures $208 million contract for ongoing supply of digital modular radio

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

DMR -- the first software-defined radio to become a standard for the U.S. Navy -- provides multiple communication waveforms and multilevel information security over four channels for secure tactical voice and data transmissions aboard U.S. Navy ships and submarines.

Information from reveals that its 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-sight or satellite voice and data communications by connecting to the MUOS satellite communications network.

The radios are also equipped with General Dynamics' Advanced Infosec Machine (AIM) encryption chip, which carries the certification from the National Security Agency (NSA) to handle classified information at the Type 1 – Top Secret level and below. The radios are able to communicate simultaneously at multiple levels of security on each of the radios' four channels.
