The weapon capabilities illustrated in the test would be useless against military targets, especially ones with no electronics fire and control systems. The principle of the weapon is to create such a large electromagnetic force field that it overwhelms the normal functionality in the opponents weapon system electronics. It's one thing to overwhelm ordinary commonplace electronics, but military designed hardware is different. Ideally such military hardware is designed to meet MIL spec 461, Electromagnetic Compatibility. I know I've designed and tested hardware that meets the spec. To knock it out with a weapon would require a huge field which implies a very huge power source. It's just not practical. For spacecraft it's a bit different, you can get a large enough field with a nuclear explosion in space. That's why most military and some civilian spacecraft are designed with radiation hardened electronic parts. I know I've done it. Such a design requirement severely limits the part selection, because there aren't that many to choose from.
So what you see is nothing more than Boeing marketing, the physics obstacles are much to great for a practical weapon.
