Lockheed Martin Wins Contract Modification for TL-29A Towed Array Sensor System

Lockheed Martin Rotary and Mission Systems is being awarded a contract modification for the production of two TL-29A towed array sensor systems.

The contract modification also includes the production of one TL-29A spare array, two array refurbishments, and additional engineering services, material and spares for the Maritime Surveillance Systems (MSS) Program Office, Program Executive Office Submarines (PEO SUB PMS 485).

The modification will increase the contract value from ~$101 million to around $152 million and was awarded by the U.S. Navy’s Space and Naval Warfare Systems Command (SPAWAR) located in San Diego, California. Fiscal 2017 operations and procurement (Navy) funding in the amount of $11.5K will be obligated at time of modification award and the contract funds will not expire at the end of the current fiscal year.

The contract work will be performed at Syracuse, New York, and is expected to be completed by February 2018.

SURTASS TL-29A

The Surveillance Towed Array Sensor System (SURTASS) Twin-line 29A (TL-29A) twin-line system is an underwater passive acoustic sensor with a pair of arrays towed side-by-side from a ship. It is developed and manufactured by Lockheed Martin.

The array was developed from the TB-29A array architecture utilized on submarines.

The TL-29A delivers unsurpassed capabilities, such as its ability to be towed in very shallow water environments in the littoral zones, to provide significant directional noise rejection, to resolve bearing ambiguities without turning, and to allow the ship to tow at higher speeds.

In addition to Lockheed Martin, the government, industry and university partnership for the development of the system includes the U.S. Navy, Chesapeake Sciences Corporation, L-3 Communications, Adaptive Methods, and Johns Hopkins University.
