didn't the German Gunners on the Bismarck have trouble with the swordfish because of the slow speed?
Plenty of reasons they didnt do too well. Weather was bad, Bismark probably working up to high speed and even a Battleship will roll and pitch at high speed, the gunners werent very good it might have been the first time they ever had to fire at a plane trying to kill them or perish the thought the extremely advanced and complicated AA system wasnt as acurate as the internet claims.
