Towed arrays are acoustic sensors attached by tow cables to surface ships and submarines, enabling them to detect sounds emitted by other vessels.
In this follow-on contract, EDO will manufacture thousands of piezoelectric ceramic cylinders, hydrophones, and micro-circuits, and then integrate them into dual acoustic-channel assemblies.
"EDO has been producing advanced sonar technology since the 1940s," said James M. Smith, EDO's chief executive officer.
"Since the early 1990's, we have supplied Lockheed Martin and the Navy with sensor technology and hardware in support of the TB-29A program. This contract shows the continued high confidence and trust that Lockheed Martin and the Navy have in EDO as a first-tier supplier of sensors for mission critical sonar systems."
