The General Dynamics Mission Systems Maritime and Strategic Systems division will provide the design, hardware and construction for the Navy’s Deep Reliable Acoustic Path Exploitation System, as well as demonstration of three DRAPES ASW arrays. The submarine-hunting arrays will be deployed in a field configuration and transmit their data for processing to the Naval Ocean Processing Facility.
Receivers on or near the water’s surface face tremendous signal interference. Noise interference drops significantly, however, as the node plunges deeper into the sea, where it can relay its sonar information to other receivers regardless of whatever weather rages above water. By solving existing communication difficulties, the sensors bolster the Navy’s anti-submarine warfare capabilities.
DRAPES resembles an project fielded by the Defense Advanced Research Projects Agency. In 2013, the agency prototyped the Transformational Reliable Acoustic Path System, which, like DRAPES, casts a wide observational net that reaches the ocean’s edges and relays that information to base.
