NEWPORT, R.I., 20 May 2015. U.S. Navy submarine sonar experts needed hydrophones for a variety of submarine sonar systems. They found their solution from Massa Products Corp. in Hingham, Mass.

Officials of the Naval Undersea Warfare Center Division in Newport, R.I., announced a $10.6 million contract to Massa Products on Tuesday design, build, and test DT-574 series hydrophones.

The DT-574 hydrophone is an acoustic sensing element with an integrally molded cable used aboard Navy Seawolf- and Virginia-class fast attack submarines, as well as on the Ohio-class ballistic missile submarine.

The DT-574 hydrophone sonar transducer is part of the Seawolf-class submarine's passive spherical array, the Ohio-class submarine's spherical and line arrays, and the Virginia-class large aperture bow (LAB) arrays.

Passive sonar aboard submarines and surface warships does not emit a sonar ping to detect other submarines and ships. Instead, it simply listens for sounds in the water that might be the tell-tale sound signature of a potentially hostile submarine.

Massa Products specializes in electroacoustic transducers and systems for commercial and military applications. Some of these devices are ultrasonic for use in air, and others are for underwater sonar and oceanographic applications.

Massa Products will deliver the DT-574 hydrophones to the Navy stock system. The company will build the sonar hydrophone transducers in Hingham, Mass., and should be finished by April 2020.
