The issue with every Eurobote other than Vanguard, the Littorios, and the Richelieu class (Dunkerque is debatable) were that they were either
actual WW1 designs- hello Warspite -or fundamentally WW1 designs, like Scharn and Bisko. Bismarck's edge is in her guns and that her armor is hilariously hard to pen in horizontal duels. That's why she bounced so much fire, because the Brits were firing horizontal for the most part, and while it utterly shredded her upperworks- poor Lutjens -and her turrets, her armor bounced most of the fire sent it's way.
On the other hand, mind, Littorio was a
great design. Tough, great guns, fast...her limitation is in crappy Italian shell quality, never having the
fuel to sortie, and being a Medbote.
Richelieu is just a great design all around. French quad turrets worked properly, she had very thick armor, and was speedy. Underrated ship that one.
Probably unnecessary technical quibble:
Nevada is considered the first USN superdreadnought.
Depends on definition of 'super-dreadnought' one uses. The
classical definition is all-centerline guns that are larger than 12-in. USN had all-centerline from the start, so that's out. But New York has 14-in guns, which makes her from a
firepower perspective the first Super-Dread in USN service.
What made them 'super' was the unprecedented 2,000-ton jump in displacement, the introduction of the heavier 13.5-inch (343 mm) gun, and the placement of all the main armament on the centreline. In the four years between Dreadnought and Orion, displacement had increased by 25%, and weight of broadside (literally, the weight of ammunition that can be fired in one salvo) had doubled
British super-dreadnoughts were joined by those built by other nations as well. The US Navy New York class, laid down in 1911, carried 14-inch (356 mm) guns in response to the British move and this calibre became standard.
Furthermore, from an armor perspective, the All-Or-Nothing design of Nevada is different from any other super-dread.
The design weakness of super-dreadnoughts, which distinguished them from post-World War I designs, was armour disposition. Their design emphasized the vertical armour protection needed in short-range battles, where shells would strike the sides of the ship, and assumed that an outer plate of armour would detonate any incoming shells so that crucial internal structures such as turret bases needed only light protection against splinters.
The United States Navy's 'Standard type battleships', beginning with the Nevada class, were designed with long-range engagements and plunging fire in mind; the first of these was laid down in 1912, four years before the Battle of Jutland taught the dangers of long-range fire to European navies.
Important features of the standard battleships were 'all or nothing' armour and 'raft' construction—based on a design philosophy which held that only those parts of the ship worth giving the thickest possible protection were worth armouring at all, and that the resulting armoured "raft" should contain enough reserve buoyancy to keep afloat the entire ship in the event the unarmoured bow and stern were thoroughly punctured and flooded.
Strictly speaking, since their turret layout and weight of fire are super-dread, one has to use the
armor definition, and look at how other super-dreads like QE compare. The Standards, with all-or-nothing really
should be their own category, and that's how I've always listed them.
