"A close-in weapon system (CIWS) is a point-defense weapon system for detecting and destroying short-range incoming missiles and enemy aircraft which have penetrated the outer defenses, typically mounted on a naval ship. Nearly all classes of larger modern warships are equipped with some kind of CIWS device."
interesting point - I don't know of any russian CIWS systems (and boy do they have 'em!) meeting success vs. drone attacks. If their systems were capable of taking them out I think they'd have crowed about any shoot downs, but what I see is a russian navy at the bottom of the sea.
Yes, add USVs to the treat list.
The type of threats these things pose are a lot more similar to missiles than they are to a Rib filled with goons. Low observable and fast, close to shore means that a high level of automation might be needed. Aka.. a ciws.
And why I think there might be add ons, is the type of threat is new and existing systems might not suffice. Magura is armored a plane or missile is not.
Please try not using initialisms that a general audience won't know. That's why i had to look up the previous one and quoted the info so other people wouldn't have to look it up also. USV doesn't even show up in a googling

EDIT
I found it, USV means a drone boat
You are right, sorry. Unmanned Surface Vehicle.
