StrategyWorld.com reports that South Korea is buying
an unspecified number of Cerberus Diver Detection
Systems to protect its harbors from attack by terrorists
or North Korean commandos. The Cerberus Diver
Detection System is a refrigerator-sized device that is
lowered to the ocean floor in the middle of the area to
guard. Cerberus uses sonar to detect anything large
enough to be a threat, up to 3,000 feet away. Cerberus
works well in shallow water, and once in place, it can be
tweaked by the operator to be even more accurate.
North Korean commandos are known to have scuba
gear, and are trained for underwater attacks. South
Korea is not specifying how many Cerberus systems it is buying or where exactly it is placing them, as that kind
of information would enable the North Koreans to plan
attacks on port areas without Cerberus systems.
There are other types of underwater weapons in
current stages of development. As we reported in our
August 2007 issue, various firms are developing sonartype
devices that can locate divers or disable them. One
device uses high-resolution sonar to create sound waves
that are tuned to cause severe gastric distress in humans,
essentially making them hurl into their regulator. But
according to StrategyWorld, this system has not yet been
made available for purchase, as there may not be a large
enough market to justify it. For all the talk about scubaequipped
terrorists, there are no official reports about
this sort of thing actually happening. Hopefully, they
won't be happening along the Korean peninsula.
