Would modern smart torpedoes defeat the battleship concept?

Would modern smart torpedoes such as Spearfish make the battleship too vulnerable?

They are a serious threat, but layered ASW, balanced supporting forces, and survivability measures can reduce the risk rather than eliminate it.

A viewer raises sophisticated modern torpedoes as a threat to the capital ship. The answer accepts that danger and emphasizes mitigation: use the layered antisubmarine systems discussed earlier and restore balanced forces capable of protecting major ships. Post-Cold War force design has often weakened that balance, making individual vulnerabilities appear without the supporting fleet context. The concept therefore depends on an ASW formation and structural resilience, not on assuming the hull can ignore an underwater hit.
