Yepper, I had a typo. I was refering to the 11" guns of the Deutchland class CA. Bismarck had 15". I would not call her AAA defence miserable though....

I believe her downfall was not her defensive wepons but her lack of escourt. Had she a propper destroyer screen about her and had the Prinz Eugen not left her while she was RTB to France, then she would have stood a chance. I think that War came too early for the Kreigsmarine and the admiralty did nto have adaquate time to prepare a surface fleet propper. This includes the KMS Graf Zepplin which was never finnished, owing alot to Goerings arrogance reguarding everything that flies is his to control thereby hindering the development of the Bf.109T and JU.87C carrier bourne craft.
Had Germany used her naval assets properly, I believe the Atlantic could have been different.
