Okay, how cool is this?

Boeing is building a laser cannon for the U.S. Army, and the new weapon has now proved it will be as capable at sea as on land. The High Energy Laser Mobile Demonstrator (HEL MD)—basically a high-energy laser mounted on top of a big truck—was successfully used to blast some UAV drones and 60mm mortars out of the Florida sky earlier this year, Boeing announced Thursday.

This test was done in a windy and foggy environment, an essential step to proving the technology is useful for naval deployment. The HEL MD used a 10-kilowatt laser—a much less powerful version of what it will eventually fire—to “successfully engage” more than 150 targets at Eglin Air Force Base, a Department of Defense weapons testing facility on the Florida Panhandle. In other words, it disabled or destroyed them.

In simple terms, the laser makes an incredibly powerful, highly focused beam of light and aims it at a moving target. Light equals heat, and, after enough heat has been transferred, the target is compromised and crashes or blows up. The Army and Boeing (which landed a $36 million contract for the project) have been working on this for the better part of a decade, par for the course for a next-generation weapons platform.

It’s a preliminary test of course –I doubt the UAVs were taking any evasive action– but the fact that the laser was effective through fog was pretty danged amazing. I can recall engineer friends back in the 80s describing the problem of lasers diffusing through fog and clouds as being insurmountable. Now? Check it off.

Which reminds me, I wonder how many of the people who called Reagan an idiot for pushing missile defense feel like eating some crow these days? The Israelis have already shown the concept works tactically on the battlefield, we demonstrated proof-of-concept with the HEL MD on our own system, and repeated tests over the Pacific show that ballistic missile defense is not at all a “Star Wars” fantasy. Other than Israel’s “Iron Dome,” these systems aren’t usable in battle, yet, but it’s only a matter of time.

Like the musket ended the age of armor, energy weapons may well spell the end of the missile age.

The next phase, of course, it to mount laser cannons on giant war robots, thus making Japanese anime a reality.

PPS: A very good book related to this is Max Boot’s “War Made New,” which covers the evolution of warfare as competing developments in technology and the effects these developments had on strategy and tactics. This is potentially the latest example.
