How 'Revolutionary' Is CHAMP, New Air Force Microwave Weapon?

CHAMP apparently includes two major parts: a flying platform and an HPM payload that can be likened to a warhead. Boeing, Raytheon and the Air Force have been vague in describing the dimensions and capabilities of both parts, except to describe the platform as a "missile." No photos have been released, but artists' renderings show a vehicle apparently similar in size and shape to Boeing's Conventional Air-Launched Cruise Missile, which is 20 feet long and 25 inches in diameter.
The platform's dimensions matter because they place physical constraints on the HPM payload, which in turn can limit the emitter's performance. Schamiloglu says modern capacitors can be scaled down to the size of a book and still be militarily useful. The component that converts energy into its microwave form, meanwhile, could be as small as a soda can, he adds. Depending on the number of capacitors stacked inside the device, an entire HPM payload could fit into the same space as a cruise missile's explosive warhead...."
