SCOTTSDALE, Ariz., Jan. 24, 2013 /PRNewswire/ -- The U.S. Army ordered kits in
December to upgrade 100 Handheld, Manpack, Small Form Fit (HMS) AN/PRC-155
two-channel Manpack radios to enable them to communicate with the military's
Mobile User Objective System (MUOS) satellite communications system. This
MUOS channel upgrade, comprising a field-replaceable power amplifier and
supporting software, will allow secure voice and data communication with the
MUOS system. The order is valued at $5 million; the kits will be delivered in
the fall of 2013.

"By upgrading fielded PRC-155 radios, the Army will greatly enhance soldier
effectiveness by providing a tenfold increase in SATCOM capacity for secure,
over-the-horizon military communications," said Chris Marzilli, president of
General Dynamics C4 Systems. "MUOS access on the two-channel PRC-155 will
also allow current Army networks to be bridged and extended far beyond their
current reach."

The two-channel PRC-155 Manpack radio also runs the essential waveforms from
the defense department library. They include the Soldier Radio Waveform (SRW)
that connects dismounted soldiers to the network, the Wideband Networking
Waveform (WNW) that seamlessly transports large amounts of data and the legacy
SINCGARS waveform for communication with existing radios. Using the PRC-155's
two-channel capability, soldiers operating on any one of these waveforms on
one channel, can interconnect with soldiers using another waveform on the
second channel. With the MUOS capability in the PRC-155, a network of
soldiers can be interconnected with others in a far distant location.

The MUOS waveform, based on the communications interface found in commercial
cellular networks, will deliver high-speed voice and data communications and
10-times greater capacity than the military's current Ultra High Frequency
(UHF) satellite communications system. With a smartphone-like flow of
information, the upgraded PRC-155 radios will allow soldiers to access the
MUOS communications system wherever they are deployed, on foot or from land
vehicles, ships, submarines and aircraft.
