Lockheed Martin won a $29.3 million contract modification to produce TB-37 Multi-Function Towed Array production units, accessories, shipping products, and spare modules for anti-submarine warfare (ASW) operations aboard surface warships.
The TB-37, part of the AN/SQQ-89(V) Undersea Warfare/Anti-Submarine Warfare Combat System, is a next-generation passive and active sonar receiver configured as a long 3-inch-diameter array that can be towed behind surface ships.
It is for Arleigh Burke Class destroyers, Ticonderoga Class cruisers, the Littoral Combat Ships, and Zumwalt Class land-attack destroyer. It is able to operate at a variety of depths to enable surface warships to detect and localize enemy submarines attempting to hide in different ocean layers of varying temperatures and salinity. Lockheed will perform work in New York, Maryland, and Massachusetts. Scheduled completion date is in June 2021.
