Although the Bismarck was completed decades after the Hood the overall design is of the same time period- to compare the Bismarck with the Yamato, Iowa or even a late war KGV (while in 1940 the P. of Whales would have still been outgunned against the Bismarck class) is hence a rather unfair comparison. I wish there was an H-Class
I hate to bust your bubble, but if you want to get into BBs never completed, look at these stats. The H class would have been in serious trouble if she had run into the Montana.

These were alleged to have been, in effect, enlarged Bismarcks. Certainly, their specifications and general layout do nothing to refute this. The areas of improvement would have been in their diesel machinery, and their 16in guns.
They seem to have retained the Bismarck class faults of single purpose secondary guns, and poorly distributed armor. They also retain the Bismarck's greatest fault, the placement of the armored deck too low in the ship to protect her vital fire control and communications links. Certainly the reversion to underwater torpedo tubes, an obsolete feature that severely compromises a ship's watertight integrity, was a mistake.
Presumably, the 'H' class also preserved the greatest advantages of the previous classes: the minute internal subdivision which made them so difficult to sink, excellent fire control, a steady gun platform (likely, given the beam of these ships), and excellent anti-torpedo protection.
Like the Bismarcks and Scharnhorsts before them, the 'H' class do not seem to have taken full advantage of their displacement. On a displacement nearly 15,000 tons heavier than the Lions they manage to carry one less 16in gun and lighter armor. On the plus side, their diesel engines should have given them much greater range than the British ships (the Germans were very aware of their lack of overseas refueling bases).
the Montanas were a magnificent design. The American 16in/50 gun was probably the best battleship gun ever produced. It threw the super heavy 2700lb armor piercing shell 42,345 yards. For comparison, the Japanese 18.1in/45 gun threw a 3200lb armor piercing shell 45,960 yards. The American gun weighed less, allowing the Montanas to carry 12 of them, for a broadside weight of 32,400lbs. The Yamatos could only carry nine of the 18.1in guns on a similar size hull with similar armor and speed. Yamato's broadside weight was 28,800lbs. The Montanas were the only battleships seriously proposed that out gunned the Yamatos.
As Wyrm stated and i reiterate, the Montana would have been the greatest BB EVER produced.
The sketch is the German H class
