The Coast Guard's newest wave of anti-terrorism tool is being unleashed on ports nationwide. The Underwater Port Security System (UPSS) can detect, track, classify and interdict intruders, and allows for the inspection of hulls and pier structures or anything that is underwater without an invitation. It adds an additional layer of protection to our ports, and is available in the U.S. anywhere and anytime. It can hear, see and talk underwater and it's compact enough fit in a large suitcase. "Terrorists are always looking for ways to attack elements of our infrastructure critical to our economy and our freedom," said Coast Guard Pacific Area Commander, Vice Adm. Harvey Johnson during a recent demonstration of the system in San Pedro, Calif.
