Description: The Deep Siren is a state of the art, long range, low frequency, submarine acoustic communications system developed by Raytheon in partnership with RRK Technologies and Ultra Electronics starting inn 1992 through 2000. Deep Siren has been designed to enhance tactical and strategic communications. The system can communicate or relaying communications through airborne platforms, surface ships, submarines and satellites employing acoustic, expendable buoys. All in, groundbreaking Deep Siren allows to submerged submarines to communicate regardless of the submarines' speed or depth.

Deep Siren communications range is dependent on environmental conditions. Although, these communications feature: reliable communications at ranges in excess of 100 nautical miles (nm); capable of operation in a wide range of acoustic environments, high tolerance to Doppler; extremely low false alarm rate; high resistance to jamming; resists usurpation; and can be used by airborne and surface platforms. Deep Siren also allows tactical communications with friendly submarines and is a key enabler of Network Centric Operations using the Global Information Grid (GIG).

The Deep Siren program is being funded by the US Navy as a critical technology for its first generation of Undersea FORCEnet communications equipment. The Deep Siren hardware consists or may consists of: surface ship towed transmitter; air launched sonar buoy transmitter for airborne platforms; submarine mounted transmitter in the ship's fin; and submarine mounted receiver electronics which are interfaced to the submarine's flank array, towed array or a fin-mounted dedicated receiver. The receiver electronics and software are the real key elements of Deep Siren.
