ASW Drones - An Update

Image
One of the areas of naval warfare with the most potential for transformation by unmanned systems is submarine hunting.  In general, anti-submarine warfare (or ASW) requires persistently deployed sensors at various water depths in order to detect, track, and identify submarines so that a targeting solution can be developed and weapons deployed against the subs.  This detect-to-engage sequence can take weeks to develop or it can occur very rapidly. Additionally, ASW is a multi-domain discipline, meaning assets are deployed above, on the surface of, and under the sea. Currently, ASW sensors are deployed by aircraft (usually periscope detecting radars, magnetic anomaly detectors, and sonobuoys) and surface ships (hull mounted, towed array, or variable depth sonars).

As one can imagine, coordinating these assets is a very complicated activity.  At some point in the future, increased levels of autonomy in unmanned systems will reduce to a degree the human coordination required in ASW. In t…
