U.S. Navy Seeks Better Sub-Hunting Technology to Counter Putin

Bloomberg – The U.S. Navy wants to upgrade its ability to detect Russian submarines in response to assertive naval moves by President Vladimir Putin.
The Navy is seeking to deploy a sophisticated surveillance device made by Lockheed Martin Corp. in the Atlantic Ocean. The device, towed by a ship, already is in use in the Pacific. As soon as mid-2016, the service also wants to send to the Atlantic a prototype networked “undersea sensor system” that “addresses emergent real-world threats.”
