You do realize that DD-532 USS Heermann sent the 65,000 ton super-battleship IJN Yamato into full retreat with a spread of 4 21" torpedoes that ended up bracketing the Yamato at the Battle of Sumar, right?
With the advent of true subs and smarter munitions, without sensors and smart munitions in play there's just subs and targets.
Does anyone want to argue that one 1 Akula or German Type 209 hiding in the littorals isn't capable of taking out any BB, provided the Destroyers can be prevented from interfering.
Honestly the DD(X) is a modern battleship, unless you only count a battleship by pure tonnage in the Dreadnought and post Dreadnought age. The point of the Battleship was to dominate the battlespace, a capacity for which the Battleships were obsolete from their inception. It was the Destroyers keeping the Torpedo boats, and subs at bay that allowed it to even have the appearance of doing so.
With the technology refinements of AEGIS and other systems that DD(X) incorporates it finally realizes that purpose.
