One word, Awesome
According to The Register, "it represents the first Detect-Thru-Engage laser shoot-down of a threat representative target in an over-the-water, combat representative scenario." LaWS is fitted to the Navy's "R2-D2" robotic gun turret and looks every bit like what you'd expect a raygun to look like.
In normal operations, R2-D2 would support the Navy's Phalanx 20mm cannon, which automatically locks onto incoming missiles and blasts them out of the sky. Unfortunately for anyone in the impact zone, that usually results in a shower of shrapnel or the 20mm shell itself if it fails to explode.
The LaWS system simply vaporizes the target.
