SCOTTSDALE, Ariz., Oct. 6 (UPI) -- General Dynamics C4 Systems of Arizona has received a $12.7 million contract from the Australian military for GPS-enabled, search-and-rescue radios.

As part of the company's HOOK2 System, the AN/PRC-112G radio sends encrypted Global Positioning System information, user identification, situation reports and other critical information to combat search-and-rescue aircraft in short bursts to reduce the risk of detection and interception.

"Twenty-eight countries are now using HOOK2 radios for their combat search-and-rescue operations," said Chris Brady, vice president of Assured Communications for General Dynamics C4 Systems.

"For NATO and coalition users, this system provides unprecedented search-and-rescue communications interoperability, enabling international forces to work together efficiently and effectively when lives are in the balance."

The HOOK2 combat search-and-rescue system comprises the AN/PRC-112G radio, Quickdraw2 Interrogator and Satellite Communications Base Station. It allows downed air crews or isolated personnel to securely contact combat search-and-rescue resources over long distances, the company said.
