Army Laser Cannon Won't Be Ready Until 2017

Late last month, officials from the Army and from Boeing presented to the press what appeared to be a working version of a mobile laser cannon.

The actual ray gun is being built under an entirely separate Army program - one that won't be complete for another five years. Integrating the truck and the laser could take another year or two on top of that. In other words, don't expect a working laser cannon until at least 2017.
