I tried this myself but not with a playable BB on Forts trying to recreate the mission with TF58,TF56 and all the battle groups that there there. The aircraft did intercept the Yamato to a point but i couldn't get them to sink her. (maybe i got too ambitious and tried to put the landing force in Okininawa as well) the planes showed up in time and attacked but most of them flew into each other, I have not tried to recreate the misson since.
