American Technology Corporation (ATC) (NASDAQ:ATCO), announced that its LRAD 1000X directed sound system was used by the Japanese Maritime Self-Defense Force to help prevent a pirate attack on a Singaporean tanker off the coast of Somalia on the weekend of April 4. Responding to a distress call from the tanker, a Japanese destroyer used LRAD’s powerful voice commands to identify itself and warn the pirates away.

LRAD directed sound products and systems communicate from 300 meters to over 3,000 meters with authority and high intelligibility through vocal commands and powerful warning tones to influence behavior, gain compliance, and determine intent. ATC’s proprietary Long Range Acoustic Devices are currently utilized in a variety of government, military and commercial applications around the world, including deployments with the U.S. Marine Corps, U.S. Army, and U.S. Navy.

With the advent of fuel transition, digitalization, AI and autonomy, innovation in vessel design and operation proceeds at unprecedented speed.
