HMS Hood equalled Bismarck's speed and firepower at long range. Had Hood not been tracking Prinz Eugen instead of the much bigger Bismarck, things could have gone quite differently.
It took only one shell from HMS Rodney to disable Bismarck, and a shell from HMS Hood would have done very close to the same damage.
The luck of war.....and the bad luck of war....
The Hood had bite there is no doubt about it. But her Armor would not have stood up for long even had the Bismark not gotten lucky.
That the Hood could give a BB the Bismark a challenge doesn't really say much for the Bismark.
Go check out the combined fleet link, they break down all the variables, like protection firepower speed, armor layout, etc. There is a lot of detail in the breakdowns that is really interesting and it doesnt just compare the bismark to a few BBs, it compares it to all its competition including the other over rated BB the Yamato.
Or pick up Fleets of WW2 by worth cheap somewhere and read up on it.
