Despite the commonly held view – among schoolboys anyway – of pirates as a bunch of peg-legged, eye-patch wearing scurvy dogs from the 1700’s (or thereabouts), maritime piracy continues to be a serious problem – and it’s on the rise. To combat this scourge of the seas BAE Systems has developed a non-lethal laser designed to act as a deterrent against pirate attacks on commercial vessels, such as oil tankers and container ships.

According to the International Chamber Of Commerce’s International Maritime Bureau, 430 pirate attacks were reported worldwide in 2010, up from 406 in 2009. Already in the first 11 days of 2011, 15 attacks have been reported, including two hijackings and 41 people taken hostage. With pirates increasing their range of operations and their capabilities, BAE Systems conducted a study of pirate’s behavior and a company-wide capability survey to examine if they had anything that could help combat the growing piracy threat.

The researchers decided that the concept of a non-lethal laser, which would leave only temporary effects, to distract and deter potential attackers from a distance was the best approach, and conducted a number of experiments to assess the feasibility of the concept. Leveraging the capabilities of BAE’s Optics and Laser Technology Department, the research team has successfully demonstrated a suitable laser at the Pershore Trials Range in Worchester over a variety of distances and in a variety of conditions.

The laser beam demonstrated is capable of providing a visual warning to pirates at distances of over 2 km (1.24 miles), while at lesser distances it can sufficiently disorientate attackers so that they are unable to target their weapons effectively, similar to the Dazer Laser.

“The effect is similar to when a fighter pilot attacks from the direction of the sun. The glare from the laser is intense enough to make it impossible to aim weapons like AK47s or RPGs, but doesn’t have a permanent effect,” said Roy Evans, BAE Systems capability technology lead for laser photonic systems.

For the tests the researchers developed a bespoke Neodymium Yttrium Aluminium Garnet (Nd:YAG) laser, which they say is an effective deterrent at relatively low power levels. By utilizing targeting systems and changing beam patterns, the distraction effect can be made more pronounced and be used against multiple targets.

“We successfully showed that the laser works not just during the night, but also in full daylight. But, there are many more requirements to meet before placing a non-lethal laser weapon on commercial ships,” Evans added.

BAE says that when it is fitted on commercial ships, the laser distraction system could use its own targeting capability or integrate with existing ship radar and sensor systems to control the direction and power of the beam, allowing it to work semi-autonomously. It would also include security features to ensure that, if the pirates did manage to get aboard, they wouldn’t be able to use the laser.

“Laser distraction is part of a wider program of anti-piracy technologies being developed by BAE Systems, including radar systems, which utilizes expertise and knowledge from the military domain. The aim of the laser distraction project is now to develop a non-lethal deterrent to pirates, which has no lasting effects, which can work in a maritime environment, be operated by the crew at no risk, and be cost effective,” said Bryan Hore, BAE Systems business development manager and the lead for the anti-piracy program.

Um its spelt Lasarrrrrrrrrr... LOL.. Sorry you brought up pirates, how was I to resist?
Chio Choi
LOL what if they use welding masks?
Bill Bennett
why not let it have permanent damage? They are, after all pirates, fry their eyes forever, must be why I have a 1000mW 532 nm laser inside my house for intruders, and well a 9mm solution, and a .380acp solution, umm and flying ashtray .41 action express solution.. and yes, these stay inside my home, I don\'t go looking for trouble kike some morons. Best, Bill

one typical attribute of lasers like this is they work at a fairly well-defined and specific frequency/wavelength. So the pirates will just wear glasses that filter the light out. Or put their hand up to shield their eyes from the light point source, whilst still being able to see the ship they are shooting at. Sounds like a pretty lame answer to me... what\'s wrong with an exocet?

I see eye patches are in again :) not harmful ... well , maybe - maybe not . three blinded pirates sail across the sea - only to starve to death .

I\'d think along the lines of removing their vessel so they have no option but to swim if they\'re lookin for humane options

What if the pirates use some kind of shields, that will allow them to still peddle towards the boat, but be \"shielded\" from the laser? I\'m not too sure they have thought this through...

Wouldn\'t it just be cheaper and more effective to give the merchants some guns? @Michael Mantion Exactly! I was thinking the same thing. Well, I was thinking some sunglasses, but similar :P

Sorry, but does \'no lasting effects\' REALLY exclude damage to the retina? I was struck my laser light (experimenter\'s kit) once for only an instant at school and my vision went from 20/20 to 20/400. There IS a need for protection for these shippers but has anyone considered just WHY they started pirating off the east Afrika coast? How about all those corporate factory fishing vessels cutting the nets of the locals and drag lining the bottom for the fish the locals depend upon? EU fishing rules require special nets which exclude some fish - allowing them to grow - harvesting only the adults. Reports tell the nets in-use off Afrika make a \'clean sweep\' of ALL fish in their way. Same thing occurred years ago in the North Atlantic and the Navies of NATO powers came to blows over it. Anyone remember the \'Cod Wars\' between Canada, Britain, Spain and Iceland?

Let\'s just hope them pirates don\'t use their brains and bring along a mirror! LOL!
