I think it`s time for some WWI stuff. Here`s the Sleipnir class battleship as it appeared in 1916:
Displacement: 33,500 tons standard, 36,000 tons fully laden.
Length: 193,3 meters o/a, 193,7 meters between pp.
Beam: 30 meters.
Draught: 9,6 meters.
Speed: 22,5-23 knots.
Range: 10,000 km at 10 knots.
Propulsion: 20 boilers, 4 steam turbines, 60,000 shp, 4 shafts.
Arnament: 5x2 15"/45 Mk 2, 14 6"/50 Mk 3, 12 3"/40 Mk 2, 4x533mm torpedo tubes.
Armor: Belt: 8-13 inches, conning tower: 15 inches, deck: 4-5 inches, turrets: 5-16 inches.
Here`s a wip of the successor to the Sleipnir class. Deisgned in the summer of 1918. It has 16 inch guns, the first battleship to use triple guns and turreted secondaries. I am planning to have three designs of varying sizes with four dual 16 inch guns, triple 16 inch guns, all casemate secondaries, all turreted secondaries and a mix of casemates and turrets, very much like the Omaha class.
Design 1 with four twin turrets and all casemate secondaries:
Design 2 with three triple turrets and mixed seconaries:
Design 3 with three triple turrets and turreted secondaries:
