My impression of WW2 is that if you have a battleship in harbour, it actually takes multiple attacks or something fairly substantial such as a magazine hit to take it out permanently; otherwise it's a case of patch it up, refloat it, and send it to a repair yard (or carry out whatever maintenance you can in the current Norwegian inlet, in the case of Tirpitz).
Granted once a battleship is in a repair yard it has at least temporarily ceased to have any immediate threat value as a fleet-in-being.
