How much sense would a riffle calibered Phalanx-like sentry gun make in an Ukrainian antidrone context?
Small arms fire is effective against the shahed drones in daytime en.defence-ua.com/…/how_ukrainian_soldiers_shot_s…
But how about a CIWS chambered in 5.56, 7.62 or 12.7? At least the first two rounds are extremely cheap compared to SAMs. So antidrone miniguns should theoretically work, but what have I missed? Why aren’t we building the guns/targeting systems?
