Another issue was that the Bismarck's secondary guns were not dual-purpose. He used a lot of weight on those 15 cm guns, and then the 10.5 cm for AA. To paraphrase a poster on navweps, there's "no business putting a secondary on a battleship that can't point up in the air."

There were a lot of BBs built inter-war that turned out to lack sufficient AAA, but it took combat to show it. Look at how many Bofors the USN ended up putting on anything and everything, for example, and that's on top of a superb dual-purpose 5 inch gun with VT fuzes.
