During this week’s defense and security expo in London German defense contractor Rheinmetall Defense Electronics unveiled a new sea-based anti-drone laser system.

The system, unveiled at the Defense and Security Equipment Industry Expo in London, features four high energy lasers mounted on turret, making it look like some kind of laser Gatling gun, Popular Mechanics reported.

The four 20 kilowatt lasers fire simultaneously, in a technique known as superimposition which combines them into a single powerful 80 kilowatt beam.

According to the company, using superimposition there's not limit to the amount of energy that can be focused on a target — just add more lasers.

Not just for drones, BTW. To read more, click here.
