However, looking in Operation Landcrab, USS Pennsylvania's ship log, USS Arizona's sister ship, has BA hull and BA main battery armor.
So how in GQ3 do you explode USS Arizona with the Ammunition critical hit from the BOMB DAMAGE table, when the it doesn't penetrate BA armor?
I took a quick look at usual sources and didn't see anything about Pennsy getting any more deck armor in a post-Pearl Harbor refit...

Pennsylvania and Arizona actually have only BB hull armor at the start of the war. So the (H)AP would be able to penetrate. Unfortunately, neither ship is included in the ship logs, but they are covered in the Deluxe Logs.I was looking through Amendment 2 and noticed something that had escaped me before: optional rule 2.8.10 H(AP) Bombs. If dropped from level 6 or higher, they penetrate BB armor. OK, sounds good. Last sentence in italics reads "An H(AP) bomb destroyed the USS Arizona at Pearl Harbor." Fine.

Well, upon further review..... This is a good example of how a new rule or change to an old rule gets done (or is this case, not done!). Generally, any change gets proposed, tested, and discussed (often quite loudly!) by the Design Team (a rather glorious term for our little band) before it goes public. Its a process that generally keeps the more absurd or obtuse ideas at bay and insures the accepted ones are at least based on good research. But, sometimes, we get caught out. Which is where our gamer community plays a very important part (we need you guys to keep us on our toes!).Pennsylvania and Arizona actually have only BB hull armor at the start of the war. So the (H)AP would be able to penetrate. Unfortunately, neither ship is included in the ship logs, but they are covered in the Deluxe Logs.
So... In this case, the Optional H(AP) rule ran afoul of 2 pieces of bad data. First, the Deluxe Ship Logs understated the armor for Arizona and Pennsylvania; the armor should be BA (not BB). (This, BTW, will be corrected in the Deluxe Ship Logs for the USN Early Pacific and Late USN Pacific and will be uploaded within the week. Anyone who has already purchased these will be able to download the correct log for free). This in turn led to the error regarding the penetration of the H(AP) bomb in the rule. As a result of Dave's inquiry (and my answer), it was realized that something was not right. Further research found that the bomb in question (the IJN 800kg Type 99 No.80 Mk 5 AP bomb) was more than capable of penetrating BA deck armor at the altitude in question (armor penetration by air dropped bombs is, at best, variable since it is highly dependent on the altitude dropped from; this was the source of one part of the error).
So, the bottomline is Pennsylvania and Arizona have BA armor and the H(AP) bomb can penetrate BA armor. A set of corrected Air Ops Charts is attached showing this amendment. And thanks Dave for catching this; sometimes we need all the help we can get!

I just purchased the US Ealry war deluxe logs, and the Arizona and Pennsylvania still have BB armor. (so do the Oklahoma and Nevada). Is this correct now?(SNIP)...

This was supposed to have been corrected, but evidently was not. A new set of files with Arizona and Pennsylvania corrected to BA will be uploaded.I just purchased the US Ealry war deluxe logs, and the Arizona and Pennsylvania still have BB armor.
