Maritime Safety

In response to the deadly October 2000 attack on the USS Cole, Genasys created the acoustic hailing device (AHD) market by developing and launching its proprietary LRAD technology and systems.

Broadcasting highly intelligible voice communications and warning tones with focused acoustic output, LRAD systems determine the intent of vessels not responding to radio calls and enlarge vessel standoff zones beyond 3,000 meters.

LRAD extends a ship’s security perimeter and provides captain and crew the critical capability of determining a threat’s intent at distance, creating more time to issue distress calls and initiate countermeasures if necessary. In most confrontations, LRAD voice and warning tone broadcasts cause attackers to abort and seek out less prepared targets.


Twenty seven naval forces throughout the world have equipped their ships with LRAD systems as an essential component of their communication and escalation of force (EOF) protocols. In uncertain situations, the EOF is increasingly initiated through hails and warnings broadcast by LRAD systems to potential threats and intruders.

Coast Guard

Coast Guard services are experiencing increasing territorial water incursions and homeland security threats. LRAD’s attention-commanding warning tones and powerful voice broadcasts enable coastal defense personnel to determine the intent of vessels not responding to radio calls and enforce marine and littoral zone regulations.

Naval Bases

The U.S. military employs LRAD systems for perimeter security and enforcement of exclusion zones around certain naval bases and piers.

Commercial Ships / Yachts

Protecting ships, passengers and crew against security threats requires a tested and proven shipboard protection protocol that includes LRAD. Commercial vessels have successfully deployed LRAD many times beginning with the Seabourn Spirit off the coast of Somalia in 2005.
