so what would, in your opinion, be a rational capital ship order of battle for both countries look like in 1939, assuming:
A) the treaties
B) German economy being decently good ITTL (or at least much better than OTL)
C) UK economy being mostly on par with OTL, but slightly worse off
D) UK political situation,had ww1 been a draw in europe (I other theatres things go as per OTL)
Dcod you detail a shipbuilding timeline for both countries?
Ps also how would a larger shipbuilding program impact funding for the royal army and RAF?
I think B, C and D are not very relevant what is agreed at A will be built, in OTL the treaties are all about saving money with no serious problems between the opponents this will be different due to Anglo-German antagonism after WWI, so likely bigger fleets.
The problem is what does each nation have at "AU-WNT"
What has happens to each nations fleets?
RN - as OTL? ie Hood as last ship?
KM - as OTL? ie B&B as last ships? What hulls does she have building if any?
USN - as OTL ie 4 Colorados building + 6 SD +6 Lex?
IJN - as OTL? ie N&M with T&K, Ax4 building?
The problem is the limits?
16" would work like OTL
35,000t only works if only Hood is over it as she was old a flawed design that was shared during WWI to USN/IJN so acceptable. This means no L20a or SDs or Tosa.
If they build to many over weights they quickly obsolete the rest of the ships in the world.
USN/IJN will not want to build more new lighter ships and scrap bigger hulls at the same time.
Then it gets difficult as how many Post Jutland ships each nation gets, but basically the following should help to work it out.
USN = RN
IJN will want 2/3 ish (60%/70%) of USN
RN will want IJN+KM
IJN want N&M as already paid for....
I understand;what,in your opinion would be tne repercussion on the funding of other services like Royal Army and RAF in a scenario where UK has to build that many more ships?
However, I think in a scenario where the UK has to build more ships this would have increasingly severe consequences for other branches of government, beginning with the army and air force. Even in our timeline, this was the case: going into both world wars, Britain maintained a proficient but small professional army that promptly proved inadequate to the array of tasks it faced in combat.
I think this is assuming that the construction costs of new battleships is very significant to the overall GB budget, I don't think it necessarily is compared to other things like the debt from WWI or other civilian programs. Remember that big new ships would allow the old ships to be scraped or put into very cheap reserve so the crew lifetime costs would not be far larger.
Also I would think that any serious challengers ie Germany buildings fleet would increase defence spending compared to OTL 10 year rule. So its likely to be a bigger slice of the pot.
Lastly this might not actually be bad thing for the general economy considering the way OTL was baddly handled with the gold standard and depression.... So might actually be a bigger pot?
