SCOTTSDALE, Ariz., Feb. 18, 2013 /PRNewswire/ -- General Dynamics C4 Systems
received a $40 million contract modification in December 2012 from the U.S.
Navy to port the Mobile User Objective System (MUOS) waveform and the
Integrated Waveform into the AN/USC-61(C) Digital Modular Radio (DMR).
General Dynamics has been delivering DMRs to the Navy since 1998. General
Dynamics C4 Systems is a business unit of General Dynamics (NYSE: GD).

The MUOS waveform allows the four-channel DMR to communicate using the MUOS
satellite communications network, the military's next-generation narrowband
satellite communications system. MUOS provides high-speed voice and data
connectivity across a worldwide network that extends into the most remote
locations. General Dynamics developed the MUOS waveform as part of the MUOS
program and has integrated it into the Handheld Manpack Small Form Fit (HMS)
AN/PRC-155 Manpack radio. The company is also building the four MUOS ground
sites that support worldwide communication from the ground to the MUOS
satellites and from one end-user to another.

The Integrated Waveform increases the communications capacity and efficiency
of legacy satellite communications networks.

"With more than 500 Digital Modular Radios in the Navy's current
communications fleet, the decision to upgrade the radios with these two
waveforms is extremely cost-effective and leverages the Navy's investment,"
said Chris Marzilli, president of General Dynamics C4 Systems.

In addition to the new MUOS and Integrated Waveform capability, the
four-channel DMR enables maritime and shore-based communications using High
Frequency, Very High Frequency and Ultra High Frequency (UHF) line of sight
communications and UHF satellite communications.

The option modifies a contract initially awarded in September 2010. The
contract authority is the Space and Naval Warfare Systems Command, for the
Program Executive Office for Command, Control, Communications, Computers and
Intelligence (PEO C4I).

Work will be done in Scottsdale, Ariz., and supports more than 100 jobs.
