Starwars Fans Have Invaded The Pentagon!

It appears that the pentagon has developed a lazer cannon which is small enough to fit on a fighter jet yet powerful enough to take out a missle. Named the High Energy Laser Area Defense System(HELADS), it is about size of a large refridgerator and weighs in at 750kg(1,650lb).

Is this really practical or do we have some Starwars fans that were hired by the pentagon?

Update: The taking out missles part wont come until the 150 kW version(2007), they are currently working on a 15kW version.
