Situated just 20 miles from Seattle, Naval Base Kitsap houses America’s most powerful and secret deterrents, a weapon that is the first line of defense for U.S. national security: U.S. Navy dolphins.
Since 1967, the Navy has been training dolphins and sea lions (and probably other marine life) for military applications such as mine clearing, force protection and recovery missions. The U.S. Navy Marine Mammal Program deployed military dolphins as early as the Vietnam War and as recently as the 2003 U.S.-led invasion of Iraq.
When protecting harbors and ships from mines, as they do at Naval Base Kitsap, the dolphins use their extraordinary biological sonar to detect hazards beneath the surface, whether tethered to the sea floor or buried beneath sediment.
If a mine or other weapon is detected, the dolphin returns to its handler, who gives the animal a buoy to mark the location of the device on the surface. Passing ships know to avoid these markers while Navy explosives ordnance disposal divers neutralize the threat below.
For protection against enemy divers, dolphins will swim up to the infiltrator, bump into them and place a buoy device on their back or a limb using their mouth. The buoy then drags the outed diver to the surface for easy capture. When trained sea lions perform the same maneuver, they use a kind of handcuff with their mouths to attach the buoy.
