General Dynamics (GD) has secured an order from the US Navy to deliver 56 AN / USC-61(C) digital modular radios (DMRs) and related equipment.
Valued at more than $29m, the latest order marks the navy exercising option five on an initial contract awarded in 2010.
The GD’s DMR radios will be able to use the mobile user objective system (MUOS) waveform, which is the digital dial tone required to make voice calls to the US Department of Defense’s next-generation, narrowband MUOS satellite communications system.
General Dynamics Mission Systems C4IRS Technologies vice-president and general manager Mike DiBiase said: "DMR is an extremely versatile radio and we continue to update its capabilities to ensure that navy communications networks have the most advanced and secure technologies.
"MUOS is an excellent example of an advanced capability that will provide smartphone-like connectivity among military personnel working in some of the toughest, most remote environments."
In February, GD announced modernisation of its four-channel DMR integrated on the US Navy vessels with high-frequency dynamic routing (HFDR) software, in a bid to add another four virtual channels.
The new high-frequency virtual channel exploitation software increases the communications capacity of DMR to 16 virtual channels when operated in the HF line-of-sight and ultra-high frequency satellite communications frequencies.
In addition, GD integrated mobile-user objective system waveform into DMR radios, which provide the same level of voice clarity and connection speeds found on mobiles.
