Hmmm...on the Tirpitz, I may have to disagree that she was a useless because she wasn't involved in real engagements and that she spent more time running. By just existing, the British considered her a threat and she is a threat. Planners are forced to often the potential threat the Tirpitz poised and allocate assets just in case this German threat show up. This would, in effect, divert assets needed elsewhere. Even if Tirpitz was a more of a haunting ghost, as a ghost she was still able to keep the British wary if not exactly fearful.
Still, I agree that the Tirpitz and her sister the Bismarck were beautiful ships to behold.
