How on Earth are you going to afford all that?

Waste not,Want not, :D :D in 21 I have adequate funds for building at least one every 1/2 year

he can afford to lay them down just like I can.  the problem is BP and compleating them in any sort of timely maner...

I think that I have more BP then him, though, and I can only afford to lay down 2 battleships every 2 years. The Oklahoma's were exceptions, much scrapping occured. The only way he could afford this is if he's building no cruisers at all.

More or less yes... Rohan can lay down 2 BBs every other year with a BC between them, but if I want to build DDs and Cruisers I have to do away with one or the other.

See.. In a war, you would be wasted by the Swiss because of a lackage of cruisers and destroyers.... 9 capital ships is no match for 70 destroyers and 10 cruisers.

9 capital ships?  try 10 modern BBs (2 more under construction), 8 older BBs, 6 modern BCs, 16 modern Cruisers (6 more under construction), and 58 DDs (8 more under construction).

Um.. GAHHHHHHHHH!!!!!

But realistically, if you lay down 3 ships every 2 years, of 30,000 tons average, you won't have much capacity for anything.
