General Dynamics Mission Systems (GDMS) has been awarded a contract modification to build and deliver digital modular radios (DMR) for use on the US Navy's new surface vessels and submarines.
Under the contract, GD will supply more than 30 new AN/USC-61(C) DMRs, along with the associated components and equipment to the US navy.
The contract modification represents the navy exercising the sixth option of a previously awarded contract to GDMS in 2010.
Work under the contract will be performed at the company's facility in Scottsdale, Arizona, US.
GDMS Radio Products vice-president Paul Parent said: "This contract demonstrates the navy's continuing trust in DMR as it keeps pace with new and innovative communications technology for sailors and their commanders to securely connect with one another anywhere, everywhere, worldwide.
"The new radios, like the 550 DMRs already delivered to the navy, are updated and upgraded using software, leaving the basic hardware in place, cost-effectively increasing radio functionality and versatility year after year."
The DMR is a four-channel radio that features high-frequency, very high-frequency and ultra-high-frequency (UHF) line-of-sight communications and UHF satellite communications to enable maritime and shore-based communications for the navy.
The radios are incorporated with the mobile user objective system (MUOS) waveform, which is a digital dial-tone required to connect with the new navy-lead MUOS satellite communications network.
The DMR radios are National Security Agency (NSA) certified, which authorises them to carry classified information at the Type 1 Top Secret level and below.
