@Twigley:
I found these figures on Wikipedia. I couldn’t find any info elsewhere about the US Pacific Fleet strength at the time - but the Japan figures tally well with those also quoted in the Oxford Companion to WWII.
IJN/US Pacific Fleet at time of Pearl Harbor Attack in December 1941:
Battleships: Japan -10…… USA - 9
Aircraft Carriers: Japan - 6 heavy and 4 light… USA - 3
Heavy cruisers Japan - 18…USA - 12
Light cruisers Japan - 20… USA - 8
Destroyers Japan - 108… USA- 50
Fleet submarines Japan - 68… 33
Midget submarines - 50… USA n/a
Additionally I found that Japan had…
90 patrol ships, gunboats, armed merchantships, and submarine chasers
6 minelayers
Itsukushima
42 minesweepers
55 auxiliaries
So it seems that Japan did have parity with the US in terms of battleships - which was wiped temporarily by the Pearl Harbour attack. She did have about 3 times as many carriers (as in the 41 set up)
The rest doesn’t work so well - as in the US has twice as many destroyers as Japan (2) in the 41 set up and the US has not cruisers to start whereas they had two thirds the number of cruiser (total=30) as destroyers (50).
Finally - we can ask how well does Japan’s round 1 sweep of the board reflect the actual damage to US fighting ability from Jan 1942 onwards:
4 battleships sunk,
4 battleships damaged including 1 run aground
2 destroyers sunk, 1 damaged
1 other ship sunk, 3 damaged
3 cruisers damaged
So we see that 80% of the Battleships were put out of action for some time. Destroyer casualties amounted to 1.5% of the available total. Cruiser casualties to 10% of those available.
Note that only (I think) 3 US ships were total write offs. So overall the amazing success of Japan in Round 1 in AA50-41 is a great exaggeration on the actual damage done. Nonetheless - it is clear that Japan did have a significant quantative and qualitative advantage in 1941. Of course over the course of the war - both of these advantages were eroded and eventually overturned.
Great info. I guess you could say that an extra Cruiser for the US would be equivalent to what remained of the BBs after PH. With this information the real error in AA50 is the American economy. AAP got it right….what is it, something like 70 ipcs for USA to 17 for Japan and the starting setup ratio wise looks similiar between AAP and AA50.
So IMO…
1. The US needs a larger income.
2. There needs to be something built into the game to make the US fight in the pacific so as there is not too large an American force crushing Europe.
3. The US needs a small addition to the starting navy.
I think you fix issue 1 and 2 with larger NOs in the Pacific for the US. Adding the Cruiser also fixes issue 3(to be placed at WUSA). This cruiser needs to be on the board after J1 attacks so either you would need to add a DD to hawaii to make the Japanese commit all out to PH or you would need to remove a fighter from the carrier group attacking
PH and place it in Japan maybe.
