I just saw in the news that Lockheed Martin had just tested a laser weapon. It destroyed a boat. Source News: http://www.engadget.com/2014/05/07/lockheed-martin-adam-vs-boat/ video of the testing While I know laser weapons are not exactly new, and there were many tests done by several countries including the U.S., Russia, China. But most of those previous tests were aimed at the air or space. Designed to blind or destroy satellites. Now this laser weapon of Lockheed Martin can be used as a CIWS (close-in weapon system). Combined with the railgun I mentioned in the other thread, I believe they can make warships much more formidable than they are now.
