Some of the biggest and most powerful ships in WWII, notably on the Axis side, spent much of their time waiting to come out to sea because, for various reasons, they could not come out through the waiting enemy or they were felt to be too valuable to risk by coming out.
If the same effort had been devoted to building and crewing, say, light cruisers, destroyers and submarines which got out among the enemy, would this have been a better use of resources?
Even if it was, would it have altered the course of the war by much in the end?
