Navy Laser

The Laser Weapon System (LaWS) temporarily installed aboard the guided-missile destroyer USS Dewey (DDG 105) in San Diego, Calif., is a technology demonstrator built by the Naval Sea Systems Command from commercial fiber solid state lasers, utilizing combination methods developed at the Naval Research Laboratory.

I read somewhere that they were working on a "blue-green" laser to work in Marine conditions....fog, heavy overcast, heavy moisture, sea spray, etc...

But if lasers are going to sea then the Chinese just got put in a hurt locker.  Every tactic that they've picked up from the Russians on how to destroy a Carrier Battle Group just got shit canned.
