The US Navy is seeking a follow-on contract from General Dynamics for the provision of digital modular radio systems.

The US Navy is requesting a proposal from General Dynamics for a five-year, follow on contract for AN/USC-61(C) digital modular radio systems.

The modular radio system is software-reprogrammable and has the embedded cryptography needed to enable the conversion between RF and baseband.

General Dynamics would provide four-channel and two-channel DMRs plus High Frequency Distribution Amplifier Group ancillary components, and the follow-on contract will provide for engineering services.

The contract may also be used to acquire DMR system-related amplifiers, combiners and couplers for SATCOM purposes.

DMR radios enable commanders and sailors to talk and share data with a wide spectrum of military radios. They use the Mobile User Objective System (MUOS) waveform to connect with the MUOS satellite communications network.

A single four-channel DMR can simultaneously support communications using single-channel Ground and Airborne Radio Systems LoS, Ultra-High Frequency satellite networks and other tactical HF radios.

General Dynamics was initially awarded a contract to provide DMRs in 2010.
