I'm trying to assess the capabilities of the Pre-Dread Battleships during WWII. Despite their old design, were they capable of defeating more modern ships, or were they hopelessly obsolete? Did the Pre-Dreads have the modern optics to outrange a modern cruiser? Did they have the armor to withstand modern 8" shells? In World of Warships the answer isn't even in doubt, but what about the real world?
To focus the debate, I'll have the Deutschland-class battleship Schleswig-Holstein stand in for the Pre-Dreadnought Battleship, famous for firing the opening shots of WWII.
Armament in 1939:
(2 × 2 – 28 cm SK L/40 guns)
For the WW2, I'll have the heavy cruiser HMS Exeter act as a stand in. She famously fought against the Graf Spee at the River Plate. She lost all her guns against the Graf Spee's 11" guns, but she survived the battle.
Armament:
3 × twin 8 in (203 mm) guns
