Talk:46cm Triple Gun Mount/@comment-25962175-20150328223830

The Japanese wiki states that the effect of the over-weight penalty on fast BBs is minor for artillery spotting. It's when you can't get air superiority (and thus no artillery spotting) that you will see a large accuracy penalty.

So if you know you can get air superiroty then 46cm are viable. If you can't then 36.5cms are probably better.
