I said"All the one anyway,the bismark would have knocked them all out"when i said all i was refering to battleships and i did conceed that the yamatos magazine was hit which would have probably finished any ship. As for your question on AA the yamato had 162x25mm and 4x13.2 mm,all this AA didnt save it so that supports my LW versus RN arguement does it not? The bismarcks AA was a paltry 16x105mm and 18x20mm Technical Layout - Armament - 105 mm-SK-C/33 (Heavy Anti-Aircraft) Technical Layout - Armament - 20 mm-MG-C/30 (Anti-Aircraft - Machine Gun)
If you follow the associated links it's pretty well explained. A very good model to use IMO. Not that I think they necessarily weighed or evaluated everything correctly but they did go into enough detail that it's possible to see how they got the rating and if you disagree with the weights or the evaluations you can recalculate the ratings without too much difficulty.
