Actual speed (unless crippled for some reason) has rarely been a critical factor in surface warship operation in the 20th century. For submarines, after diving, it's entirely different.
 
Of course, if a ship doesn't have enough power to reach her theoretical maximum, the maximum is irrelevant.  Otherwise the longer the ship the faster she goes.


Yes.  The new battleship classes were different in dimension , displacement and power plant.  They all mounted the same main armament.

The North Carolinas (2) were not identical, but they were close enough:  approx. 38,000 - 45,000 T., length 728 ft., beam 108 ft., 121,000 horsepower, 28 knots.

The South Dakotas (4) were approx. 38,000 - 44,000 T., length 679 ft., beam 108 ft., and they needed 130,000 HP to make 28 knots.

The Iowas (4) were 48,500 - 57,000 T., length 886 ft., beam 108 ft., and had 212,000 HP that could make 33 knots.

Saying 'speed has rarely been a factor' wasn't quite right, but I'm having trouble determining the best way of putting it. Obviously the fact that the British fleet wasn't fast enough to catch the Germans after Jutland made a lot of difference to the battle.

Maybe what I meant was 'difference in speed in ships of the same category' has rarely been a factor.
