Also Yamato would out range the Bismark by several thousand yards, so she could get off several shots before Bismark could even get in range, and if one of those shots hit the Bismark then she would have lit up like a Christmas tree. If the Bismark was not already destroyed when she got in range of the Yamato even if she hit the Yamato she could never penatrate the Yamato's turret armor. Japanese radar was reliable and duralbe, and withstood shock well beacause it was cruder and lacked as many sensitive advanced parts. Therefore, even if the ship the Yamato somehow was sinking, it could still probally fire because the fire contorl would probably not have been taken (there is also the fact that the fire control was way up on the massive pagoda structure).
I vote Yamato
