Contracting under Raytheon Integrated Defense System, working for the U.S. Navy, Teledyne Brown produced several sections of the Sonar System. The AN/AQS-20 Mine-Hunting Sonar System uses five separate sonars in a compact lightweight and hydrodynamic towed body. The AN/AQS-20 is used to provide real time, computer-aided detection and classification against the full spectrum of mine threats. When the AN/AQS-20S algorithms locates a mine it automatically provides the operator with a visual image and contact data list.
For this contract, Teledyne provided tasks required to manufacture, assemble, integrate, and test the tail cone and midbody sections. This process required extensive five-axis milling. Also, electron beam welding, and ceramic bonding were used to ensure the integrity of the outer hull. Teledyne’s in-house QA performed no-destructing x-ray inspection as well as leak testing on the final product before it was delivered on schedule. ​
