I just did the Allied Dec 8 turn. I didn't find anything out of reason. The Pearl Harbor attack is pretty brutal, there are a lot more aircraft available than in stock.

Your Post made me think about the actual RL starting numbers vs what we have in BTS.
Here are the numbers of aircraft:
Real Life--108 Zero, 135 Val, and 144 Kate
BTS--212 Zero, 144 Val, and 180 Kate
Total of 387 Planes versus 536.
Thought it was interesting to see the preponderance of weight is in Zeros with near the same number of Vals and 36 more Kate. Very interesting...

These are comments that Michael has been sending me. Anyone got thoughts to these points?
1. Not to nitpick, but I think the admirals are wrong on KB – 1, 2, and 3. Should have Nagumo in KB-1, Yamaguchi in 2, and new guy in 3.
2. What follow up forces would be starting to prep for any of these four objectives? With Combined Fleet at Saipan, would they draw down the BFs there for any of those bases? Thinking there needs to be a BF and maybe a construction for each to repair bases after capture. Need an Air HQ to be able to go to Rabaul or elsewhere. Right now they are at Truk and Roi-Numur. Should there be a third at Saipan? Move an Air Div from Home Islands down?
3. I’m taking my time with turn 2. I hit the “J” button to look at Airframes and R&D. The following airframes should be changed to something else.
Osaka = Zeros (x2) at 10; Jake 8; Frances (x2) at 5
Yokohama = Kate at 15
Tsu = Jill at 8; Betty G4M2 at 3; Rita at 2
Nagoya = Val at 27; Judy (x2) at 7 & 9
Gifu = Val at 15; Topsy at 6
Nagasaki – Jake at 15
Sendai = Oscar Ic at 12
Harbin = Oscar Ic at 25
Utsonomiya = Tojo IIa at 20
Kobe = Nick d at 5; Rex at 10
Tokyo = Helen at 20

Will check the Omaha-CL---CLAA Conversion. Make sure that is OK.

That shouldn't happen...rather strange...
The I-400s? Hmmm...
I did not know they were Yamamoto's idea. Where did you read that?
Hii I read on wiki if that counts.

The I-400 class was the brainchild of Admiral Isoroku Yamamoto, Commander-in-Chief of the Japanese Combined Fleet. Shortly after the attack on Pearl Harbor, he conceived the idea of taking the war to the United States mainland by making aerial attacks against cities along the U.S. western and eastern seaboards using submarine-launched naval aircraft. He commissioned Captain Kameto Kuroshima to make a feasibility study.[3]
Yamamoto submitted the resulting proposal to Fleet Headquarters on 13 January 1942. It called for 18 large submarines capable of making three round-trips to the west coast of the United States without refueling or one round-trip to any point on the globe. They also had to be able to store and launch at least two attack aircraft armed with one torpedo or 800 kg (1,800 lb) bomb. By 17 March, general design plans for the submarines were finalized. Construction of I-400 commenced at Kure Dock Yards on 18 January 1943, and four more boats followed: I-401 (April 1943) and I-402 (Oct 1943) at Sasebo; I-403 (Sept 1943) at Kobe and I-404 (February 1944) at Kure. Only three were completed.[4]
Following Yamamoto's death in April 1943, the number of aircraft-carrying submarines to be built was reduced from eighteen to nine, then five and finally three. Only I-400 and I-401 actually entered service; I-402 was completed on 24 July 1945, five weeks before the end of the war, but never made it to sea.

I noticed that my game started off the Jap side with no VEH points, and I'm wondering if it was supposed to be that way.

Thank you very much John dude. I've sent an inquiry to Brian to see if he wants to forgo the rest of the playtest and launch into a 'real' game with him as the Japs. I haven't heard back yet but I have my fingers crossed.

Bases #1559, 1563, 1577, 1579 still have their HQ as Chungking, which is an unknown HQ in tracker.

I looked and both stock and DBB have the same thing. I don't know why.

Can easily change those dates if you want. Could spread them 3-4 months so it isn't a real big deal.
Will check the base numbers. Did not see that earlier. My fault.

Base # 1562, does not have nationality code, so does not show up on the map. It also does not have an HQ assignment.
