Anti-swimmer dolphins ready to defend Gulf - Around the Fleet

All Hands, Sept, 2003 by Josh Frey

With terrorist attacks like that against USS Cole (DDG 67) in October 2000 still a very real possibility, the U.S. Navy has a new ally in the global war on terrorism--the Mk 6 anti-swimmer dolphin system.

Much more than your typical Sea World entertainers, these dolphins are dedicated Navy Sailors, standing watch over Arabian Gulf ports and deter ring uninvited guests seeking to harm ships and ports. With swimmer defense experience dating back to Vietnam, the Navy's Mk 6 dolphins are ready to deploy any time, anywhere.

"It is reassuring to know that we can put our anti-swimmer dolphins where we need them rapidly and successfully, to protect our Sailors, ships and high value assets," said LCDR Martin Anderson, U.S. Naval Forces Central Command's Special Operations branch officer. "These dolphins and their handlers provide a valuable capability, by guarding U.S. and coalition ships and piers in the waters of not only the Arabian Gulf, but throughout 5th Fleet waters."

Taking over from the Sea Lion Shallow Water Intruder Detection System, the dolphins, operated by Explosive Ordnance Disposal Mobile Unit (EODMU) 3, provide significant operational force protection capabilities to the 5th Fleet theater. The Navy's selection of bottlenose dolphins and California sea lions for its operational systems is based on a variety of factors, one of the most important of which is their ability to work comfortably and effectively in a wide variety of environments.

"They're able to adapt rapidly, and their biological sonar is very effective," said Naval Space and Warfare (SPAWAR) representative, Mark Yates, referring to the mammals' special natural adaptations, such as an efficient hydrodynamic shape, and a very effective natural sonar system that can transmit and receive sound waves.

"The adaptations make the animals valuable partners in detecting threat swimmers," added Sonar Technician (Submarines) 1st Class Dan Cook of EODMU 3.

"Hardware-based systems have limitations that the dolphins make up for naturally. This helps them discriminate between objects and swimmers and is particularly helpful in high noise environments, such as harbors and bays."

The previous deployment to 5th Fleet by the sea lions gave the EOD team valuable experience and knowledge of marine mammal systems.

"We used the data from the sea lions, as well as data from previous marine mammal deployments to the Texas Gulf Coast, to develop climate controlled facilities for the mammals and enhance warm water operations," explained SPAWAR veterinarian Cynthia Smith. "They have quickly acclimated to operate effectively."

With capabilities that humans and hardware lack, the swimmer defense dolphins provide a formidable defense for U.S. Navy ships and facilities. Their ability to operate in diverse environments make them easily deployable to other areas in the Arabian Gulf, providing stability in the region, and a strong deterrent against terrorist attacks.
