The Navy is turning to General Dynamics for a large order for marine on-board radios

SAN DIEGO – US Navy ship communications experts ask General Dynamics Corp. to provide marine radios AN / USC-61 (C) to enable naval warships and submarines to communicate on high frequency (HF), ultra high frequency (UHF) line of sight, UHF satellite communications (SATCOM) and very high frequency radios frequency (VHF).

San Diego Space and Naval Combat Systems Command (SPAWAR) officials announced on Wednesday a $ 198.1 million contract for the General Dynamics Mission Systems segment in Scottsdale, Arizona, to build the AN / USC-61 (C) digital modular radio (DMR) systems.

The contract includes high-frequency distribution amplifier groups, spare parts and engineering services for continuous field and maintenance of the marine radiocommunication system.

AN / USC-61 (C) is a marine software-defined radio (SDR) that has become the standard for the US military. The compact multi-channel DMR provides several different waveforms and multi-level information security for voice and data communication.

The radio includes built-in type 1 encryption; built-in red / black switching and routing of the main band; implementation of a joint site; reduced labor requirements; single control point for radio frequencies HF / VHF / UHF / SATCOM; and built-in test (BIT).

Software-defined radio waves are computer programs that allow SDR-enabled radios to operate on different bands with different encryption and cybersecurity features. AN / USC-61 (C) operates on the Navy surface ships, submarines and other military platforms using frequencies from 2 MHz to 2 GHz.

General Dynamics is DMR certified for transmitting voice and data protection to multiple independent security levels (MILS) over HF, VHF, UHF and SATCOM channels and to withstand the effects of electromagnetic interference and other severe operating conditions.

The DMR is also certified by the Joint Interoperability Testing Team (JITC) to meet U.S. Government MIL-STD-188-181B / 182A / 183A requirements for UHF SATCOM. General Dynamics builds AN / USC-61 (C) using open architecture standards.

This contract has a five-year contract period up to the award amount and has one option that can bring its value to about $ 208.9 million. General Dynamics will complete work in Scottsdale, Arizona, and should be completed by December 2022.
