Did we even try? We have Phalanx systems that should easily take care of these drones.
That’s a little like throwing coke bottles at mosquitoes. You might hit a few, but probably expend all your ammo doing it. My understanding is that the reload time for a Phalanx gun battery is on the order of 5 or 10 minutes.
Still, it’s your only system that has any capability against that threat, so it should have been tried.
Don’t mean to suggest that Phalanx is slow firing. Quite the opposite. But changing magazines out isn’t like switching out on an AR.
