NAVAL DRONES

A frequently cited fact in my days training to be a naval officer was that the most common weapon for damaging a warship since World War II was the naval mine . The recently concluded International Mine Countermeasures Exercise 2012 (IMCMEX 12), held in 3 distinct OPAREAs throughout the U.S. Fifth Fleet Area of Responsibility (AOR), demonstrated both the difficulty of mine countermeasures (MCM) operations (detecting and clearing mines) and the potential of new technology to mitigate those dangers. PBS’ News Hour quotes a retired naval officer and observer of the exercise, Capt. Robert O’Donnell, stating of the 29 simulated mines in the exercise, “I don’t think a great many were found…It was probably around half or less.” The response from the Navy is a little confusing: The Navy declined to provide data on how many practice mines were located during the two-week naval drill but did not dispute that less than half were found. However, a spokesman insisted that the figures do

As the recent Israeli shootdown of a Hezbollah UAV reminded us, it is relatively easy to destroy an unmanned aircraft. But what about the proliferating numbers of unmanned undersea vehicles?  The growth in these systems for naval applications will inevitably result in the requirement to counter an adversary's underwater drones.  Detection of a small man-made object moving underwater is not trivial, but also becoming easier with the advent of technologies such as high-resolution imaging sonars and Light Detection And Ranging (LIDAR) systems. However, once an AUV is detected, how can it be destroyed?  This problem set isn't new. Mini-subs and combat swimmers have threatened ships in port since World War II.  The old school way of dealing with frogmen is to drop a concussion grenade over the side of a boat.  Alternatively, some navies have experimented with  dolphins  to counter swimmers.  These sorts of mammal-based systems could conceivably be trained to work against AUVs.
