COMMUNICATIONS EQUIPMENT: General Dynamics digital modular radios selected by U.S. Navy for new ships and submarines

The General Dynamics Corp. C4 Systems segment in Scottsdale, Ariz., will provide 53 additional AN/USC-61 four-channel digital modular radios for new Navy ships, submarines, and inshore sites.

General Dynamics is doing the work under terms of a $35 million contract option. Company engineers also will modify existing digital modular radio hardware to accommodate government networking waveforms.

Digital modular radios operate aboard U.S. Navy surface ships, submarines, fixed sites, and other U.S. Department of Defense communications systems using frequencies ranging from 2 MHz to 2 GHz.

Certified to pass secure voice and data at several independent levels of security over HF, VHF, UHF, and SATCOM channels, the digital modular radio meets Navy specifications for environmental, EMI, and performance.

The digital modular radio also 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.

The multi-channel digital modular radio, adopted by the Navy in 1998, provides multiple waveforms and multi-level information security for voice and data communications from the core of the network to the tactical edge.

Built using open architecture standards, this General Dynamics digital modular radio is capable of simultaneous, secure short-range and global communications on any of its four channels.

The radio is interoperable with legacy military radios and was the first software-defined radio certified by the National Security Agency to protect information classified at the Top Secret level and below.
