The best diesel submarine killer might just be a drone:
Originally conceived as a DARPA project, the Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV) is designed to hunt the next generation of nearly silent enemy diesel submarines.
Diesel submarines are quickly proliferating around the world due to their low cost. Russia recently announced that it has launched the world’s “quietest submarine.”
To accomplish its submarine-hunting mission, the ACTUV project is structured around three primary goals: the ability to outmatch diesel submarines in speed at significantly less cost than existing systems, the system’s ability to safely navigate the oceans in accordance with maritime law, and the ability to accurately track diesel submarines regardless of their location.
If we want to keep the peace in the Pacific, forget about TPP — this DARPA program ought to get the fast track.
