O.k. - Time for some facts.
I don't want to make uber capships.
In DOTA we have a 95m bomber with 6 turrets, 5000 shields, carrying bombs that do around 25000 damage each. So as you can see, that's a whole lot of firepower. Alltough it can barley outrun a cruiser and handles like a brick.
I want to make warship classes act like they should. You can still destroy them, only it will take more effort.
Battleship were designed to stand alone and survive. That's why they had thick armour, and loads of guns. They weren't unsinkable.
Every ship should have his role and act acordingly.
Carriers ar weak, but they carry lot's of fighters/bombers to conpensate that.
Cruisers are even weaker, but they have great AF weaponry.
Battleships are fortresses that require lot of effort to take down.
Fighters engage other fighters and intercept bombs/bombers
Bombers take out heavy warships, but they can't do it on their own (someone needs to draw the fire away)
That's how I want to make it in the DOTA. And the player would have a effect on the outcome. The only difference is he wouldn't be the centre of the universe, and in most cases, he won't be able to do it alone.

As far for the Bismarck. The British did pound him good, but they weren't abe to sink him.
The armour around the waterline was too thick. Alltough the armour drops to around 100mm near the front, no critical areas are there and if all the water-tight compatments (bulkheads) are sealed, t's practicly unsinkable. You can turn it into a burning wreck, but it would still float and would probably still be a ble to shoot back.
Like I said, the main turrets, command tower, ammo & fuel storage and the center waterline were so heavily armoured that only a battleship with bigger guns that Bismarck could punch trough the armour.
Even torpedos aren't too effective, since a battleship has triple-layered hull, and torpedo shields (extra extrusions to stop the torpedos).
I do belive the Germans scuttled him, alltough I can't rightly remember!
