Raytheon Helps Navy Build Lightweight Anti-Submarine Sonar Tech

Raytheon and its partners have built a small single-tow sonar technology designed to help the U.S. Navy detect near-shore submarines from littoral combat ships and  aircraft carriers.

The company said Wednesday development of the Dual-mode Array Transmitter Mission System commenced in 2012 after the military service announced it needed a sonar that has reduced weight and minimal impact to a small crew’s launch and recovery missions.

Upon securing the contract, the company worked with Naval Undersea Warfare Center personnel based in Newport, R.I., and conducted land-based tests, full integration, operations and maintenance training in partnership with the Florida Atlantic University’s Harbor Branch Oceanographic Institute.

Raytheon’s team members on the project were L3 Technologies’ Adaptive Methods business, Purvis Systems, Indal Technologies, Southbay, Seacon and SeaCorp.

DART MS works to locate and thwart submarines while being towed at a speed faster than traditional anti-submarine sonars, Raytheon noted.
