Boeing's Enormous Navy Laser Cannon

An anonymous reader writes "Boeing is working to build a huge, incredibly powerful, soon-to-be-seafaring laser for the US Navy. This free electron laser can produce light of any wavelength (ie, color) directly from an electron beam, and gets an energy boost from a superconducting particle accelerator. Once it's onboard ships, the laser could be used to shoot down cruise missiles and artillery shells."

Wow!

Imagine the size of those sharks required for such huge laser weapons.
