I have a test area in mind. Rio Grande Valley.
I was so lucky to be stationed in the Army where the AC-130 would routinely have live fire exercises. My buddies actually called in airstrikes danger close which saved them in combat.The B-52,A-10 and AC-130 are aircraft that are pure American military excellence.
If not a weapon, it would certainly serve well as a platform to laser a target for a bomb from a distance instead of having to put a soldier/Tacp on the ground close enough to be attacked.
