"A new laser gun mounted on the USS Ponce has been operational for months in the Persian Gulf, and it has exceeded expectations as far as its range and durability, senior Navy officers said Wednesday.
The Navy calls it the LaWS, short for laser weapon system. It was installed on the Ponce over the summer, and deployed this fall. Video released by the service on Wednesday shows it taking out an incoming speedboat in a test at a long, undisclosed range with directed energy. No laser beam can be seen, but the boat bursts into flames."
(This gun must have something pretty special inside.)
