L-3 to build submarine towed array sonar systems with enhanced capability and reliability
Officials of the Naval Sea Systems Command in Washington are asking L-3 to provide TB-34X towed array assemblies and cable assemblies. The TB-34X is a submarine fat line towed array passive sonar receiver It is in the same form factor as the TB-34 array, yet it provides increased capability, reliability, and ability to resist the effects of obsolescence.
The Navy's TB-34 towed array is replacing the TB-16 legacy array, and provides enhancements to towing and self-noise characteristics compared to the TB-16. It provides more hydrophones than the TB-16 for future capability in passive sonar processing.
The TB-34 towed array is one of several acoustic sensors that provide data to the Acoustics-Rapid Commercial Off-the-Shelf Insertion (A-RCI) sonar system installed on U.S. fast-attack, ballistic-missile, and cruise-missile submarines.

The array is to provide improved capability for anti-submarine warfare (ASW), and will help submarine crews avoid threats in cluttered undersea areas near coastal waters and harbors.
The TB-34 towed array's primary function is to help search for, detect, track, and attack enemy submarines and surface vessels in coastal waters and in the open ocean.
On this order L-3 Chesapeake Sciences will do the work in Millersville, Md.; Liverpool, N.Y.; and Ashaway, R.I., and should be finished by September 2021.
