Most U.S. aircraft can deliver weapons well outside 6 miles to target.

The further the EMP weapon is from the protected asset, the more of them you need.

So, these defenses need to be at a price point to consider them effective in protecting a small number of high value assets.

One wonders how focused this cannon is? How narrow the beam? How much does the beam spread?
