Ah that’s my mistake I thought they meant a drone swarm as in the switchblades kamikaze drones. I’m not too familiar with naval drones but from my understanding it’s a bit like a waterborne VBIED almost right?

Maybe I’m ignorant of their capabilities but I feel like CIWS should be able to engage it in addition to other weapons systems such as missiles and energy weapons. Would love to read more about these kind of drones either way.

The warhead needed to sink something in that tonnage is pretty hefty. You’re gonna need a drone with a lot of payload and kinetic energy to do serious damage. Not to mention CIWS and other defensive countermeasures.
