The US Army is getting laser cannons courtesy of Boeing

Boeing has a pretty storied history with lasers and now its testing one that can take out UAVs and rockets regardless of where it’s installed. A recent trial run of the tech was conducted in Florida under some pretty grueling conditions (heavy fog, rain and wind), to prove that even a lower-powered version of High Energy Laser Mobile Demonstrator is capable in a maritime environment. As Boeing tells it, the firm exceeded all of its goals and successfully engaged with some 150 different targets including drones and 60mm mortar shells with its 10 kilowatt laser.

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.
