How Maine Helped Repel the Pirates

In the recent attack on a cruise ship off Somalia, the pirates were repelled with the help of technology developed right here in Maine.

The Seabourn Spirit was equipped with a Long Range Acoustic Device (LRAD), which produces a 2,100-3,100 hertz sonic blast. The system was created by American Technology Corp., whose government sales and systems engineering division is located in Topsham.
The purpose of the devices on cruise ships is generally to communicate with "mom and dad in the Bayliner" boat from getting too close to the ships, said [ATC anti-terrorism/force protection program manager A.J.] Ballard. They can send a narrowly focused audio message up to 300 yards away - the sound is heard by the group targeted, not by others.

"However, we always saw repelling borders as a possible use for the LRAD," he said. [Link]
