Raytheon’s 5th generation hull mounted sonar to enable anti-submarine, undersea warfare

Raytheon Company was awarded a sub-contract from Science Applications International Corporation (SAIC) to deliver its first 5th generation medium frequency hull mounted sonar system as part of the Defense Advanced Research Projects Agency (DARPA) Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV) program.

According to the U.S. Navy, 43 nations operate more than 600 submarines; the steady increase in undersea vessels makes tracking a challenge. Raytheon’s Modular Scalable Sonar System (MS(3)) will integrate into SAIC’s prototype trimaran vessel as the primary search and detection sonar. The system( )is designed to provide search, detection, passive-threat filtering, localization and tracking capabilities without requiring human operation.

MS(3 )enables anti-submarine warfare (ASW) and undersea warfare with capabilities such as active and passive search, torpedo detection and alertment, and small object avoidance. Data from multiple sonars may be fed to a central command and control node, providing a common operating picture as part of the ASW mission. By integrating a host of capabilities in a single sonar system, Raytheon delivers an affordable solution that addresses critical naval challenges.

“Historically, manned sonars were central to anti-submarine warfare missions. However, the growing number of submarines traversing the world’s oceans makes this model unsustainable,” said Joe Biondi, vice president of Advanced Technology for Raytheon’s Integrated Defense Systems business. “By leveraging Raytheon’s heritage in developing undersea sensors, MS(3 )can be configured to provide the capabilities required for ASW in an autonomous environment.”

DARPA drone ship tracks submarines – Video Clip

DARPA – the Defense Advanced Research Projects Agency – is known for designing a variety of high-tech and futuristic platforms for the US military.

One of the most recent projects from DARPA? An oceangoing drone ship specially designed for submarine hunting by engineers at SAIC.

The ship – dubbed the ACTUV sub-tracking drone – is specifically built to monitor very quiet diesel-electric submarines. In terms of real-world scenarios, the Navy would deploy sonar buoys around a specific area to give the drone ship an idea of where to search.

After the search area is defined, the drone ship would be capable of taking over the search using long-range and short-range sonars for up to 13 weeks at a time. The ship is also able to detect and gauge the intent of other ships in its path, with human failsafes built into the system.

The ACTUV is currently categorized as a work in progress, so it will be years before the vessel is actually ready to plow through the oceans searching for enemy submarines.

SAIC says the ship won’t requires human interaction or maintenance for the entire term of its 60 to 90 day deployment. Indeed, the only time human assistance is needed during the ACTUV mission is when the harbormaster escorts the ship out of the dock.
