2.5 mile range laser gun keeps Somali pirates at bay

laser system from LaserSec has a deterrent and sickening effect. In some cases, this laser weapon even causes vomiting. The claimed range is up to 2.5 miles (approx. 4,000 meters).

Piracy is a continuing threat to international shipping. Due to various reasons, governments and ship owners are reluctant to implement armed security on board vessels. Companies are therefore constantly looking for other ways to stop their vesseld being hijacked by pirates. The resources already in use range from the use of water cannons to the use of support vessels.

SeaLase was developed by Finnish company LaserSec. The SeaLase is a proven system that was also used by the U.S. army to control riots in Afghanistan. The system was tested by NATO in 2009 and is now in use on several ships and super yachts. The system is easy to install and is supplied with advanced aiming tools. The guidance systems are based on thermal imaging and use of so-called gyro-stabilization and radar tracking so effectiveness is guaranteed even at rough seas and with relatively small targets.

The system is claimed to not cause permanent injuries or damage, making it an effective, proportionate and humane way to deter pirates.

The SeaLase system is commercially available.

In one case, the group found that a green laser pointer emitted almost twice its rated power level of light
