The Undersea Weapons Office supports the U.S. Navy in its efforts to defend surface ship’s and submarines against torpedo attack. Utilizing the rich array of academic and research assets that ARL has available, the office develops capabilities for the detection and defensive engagement of threat torpedoes. Building on the Laboratory’s experience in undersea weapons, acoustics, signal processing, modeling and simulation, energy and power systems, systems engineering and hydrodynamics, Torpedo Defense has been an important core competency of ARL for more than a decade.
