You grossly underestimate how hard it is to sink a warship. During SINKEX live fire exercises that use a retired US Navy ship as a target, they will usually absorb many hits with state-of-the-art weapons without sinking, even though the active defenses are turned off. This is several thousand kilograms of explosive with terminal guidance smart enough to find the most vulnerable part of the ship.
Typically, they have to send a specialized demolition team to actually sink the ship after the exercise is over.
To a first approximation, US Navy ships are demonstrably unsinkable. That has always been a hallmark of US Naval architecture, and they are rightly proud of it. The idea that it is possible to destroy these ships with tens of kilos of explosives delivered by cheap drones isn’t serious.
