Let me just clarify a few points.
First, RA has hit the nail on the head, many of these vessels are already in service. Building three destroyers a year will achieve the bulk of my target and foreign ships and older ships will also count. By the end of 1931 I'll have five new DD.
Second, who mentioned carriers? I said aircraft carrying vessels, they could be seaplane tenders or hybrid crusier/carriers.
My planned BC (one so far) is something different, no details yet so when I reveal it it will be a fresh design. The BB are already in service and won't be replaced just rebuilt.
It is only a plan, things may change, that why I have split it into two five year plans. Along with all this there has to be an industrial expansion. Manpower may be a problem but conscription should help.
My fleet follows my own views. Here are the hints of the future. I dislike huge super-BB and heavy ships, I dislike battlecruisers (mine are not like Renown). I believe in using more effective weapons to destroy ships. The torpedo and speed is what I want allied to numbers. Using loads of cheap, expendable ships will be better than building a few large and expensive units I can't afford to lose.
