From: Iowan in MD/DC
I've got a related question... In my most recent AI start as Japan, I transferred some of the B5N1 and Mabel groups (4 in total, I think) to the KB, hoping to get some extra "oomph" on the Pearl Harbor strike. None of the extra planes flew on December 7.
On December 8, I was able to get one of the extra groups on Akagi to fly, and one of the groups on Soryu, plus some Zero escorts. The groups on Kaga and Shokaku stayed onboard. After December 8, I couldn't stick around because I got exceptionally poor results on the airfield/port strikes on the 7th (not a single BB sunk!).
Akagi had 5 groups. Clearly she was still conducting air ops, but the extras weren't flying. I changed the commanders before December 7 so that they had 50+ in Ld/Insp, as well as 67+ in Air and Aggression, so two days in a row of failed checks shouldn't be all that common... I ran the December 7 turn 3 times - they never flew. Now, I know that there is a huge chance (guaranteed at 400+ planes?) of uncoordinated strikes when you have X number of planes in the TF, but can someone please give some possible reasons why what I tried didn't work?
For the December 8 strikes, I even tried splitting the KB into 2 TFs with 3 CVs each, and just over 200 planes. Ran that turn twice, and both times just the Akagi/Soryu extra groups flew. The 2 TFs were Akagi/Kaga/Shokaku and Hiryu/Soryu/Zuikaku. I had also made sure that none of the CVs had more than 110% capacity, and I think only Akagi was actually over capacity by more than 1-2 planes (but even she was under 110%, and well shy of the 115% limit).
