Rockwell Collins recently provided enhanced networking communication capability to the Royal Canadian Navy fleet by completing delivery of the company’s 721S radios.

“The 85 radios, delivered on-time and on-budget, will enable the RCN to fit their main combatants and allow them to take full advantage of the wideband data throughput of their SNR systems,” said Alan Prowse, vice president and managing director for the Americas for Rockwell Collins. “The RCN is a strong supporter and early adopter of the Canadian-developed SNR capability, which is now fielded internationally.”

Prowse added that the Royal Canadian Navy is the latest in a series of militaries to acquire the 721S radio for naval operations. The growing popularity of the 721S is largely driven by its proven ability to meet the throughput and data needs of Rockwell Collins’ SubNet Relay system.

“The successful fielding continues the strong relationship Rockwell Collins has developed with the RCN over the past two decades as our company continues to work closely with them and allied nations on developing appropriate communication systems to meet their operational needs,” said Prowse.

The 721S is among an elite class of radios designed and tested to operate with SubNet Relay at data rates as high as 2 megabits per second in a 500 kilohertz channel, providing the advanced communications capability that is required today.

The 721S radio, a drop-in, software-defined radio replacement for the legacy Rockwell Collins AN/GRC-171 communications system, requires only five minutes to install, weighs 60 percent less than its predecessor and offers vastly improved capabilities. It is fully interoperable with legacy radios in use by coalition forces and includes a new remote control feature that allows customers to upgrade their installations for “lights out” operation, reducing manpower needs. The radio also features Rockwell Collins’ patented Clarity™ technology, which eliminates background noise in both transmit and receive modes and provides four times the communications coverage compared to legacy radios.
