My German 1911 battlecruiser design evolved from a concept for a fast armored cruiser. the original concept was for a 14,000 ton ship with 8-9.4in (25 ton) guns and a 6in belt. The 9.4in (24cm) gun was intended to fire a 419lb APC shot.
The next step in the evolution was a 20,000 ton battlecruiser with 6-12in/50 guns and a 6in belt. This design was filled out more, and the dimensions were 725ft x 80ft x 22.7ft. The Cp was 0.56 and the Cm was 0.95. The hoped for speed was 33 knots. The armor was restricted to a narrow patch amidships, with 3in+2in decks and a 1in A/T bulkhead.
The final design was much larger: 35,000 tons legend displacement. The final dimensions were 750ft x 100ft x 30.1ft, with Cp=0.56 and Cm=0.97. The hull depth was 55ft. The armament was still 6-12in/50 (66 ton) and 8-6in (8 ton). The main armament was in two triple 12in turrets, superimposed forward. The power was 140,000 SHP. I was hoping for 30 knots.
The weights broke down as follows:
- oil fuel=6000 tons (full load)
- feed water=750 tons
- armament=1062 tons
- protection=9128 tons
- hull=12,300 tons
- machinery=3,500 tons
- miscellaneous=2,260 tons
The protection was an inclined belt (4in-8in), 5in upper deck and 3in lower deck, and 2in A/T bulkhead. The uptakes had 4in armor above the upper deck and 2in between the decks. The turrets and barbettes were 8in. The conning tower was 8in with a 4in comm tube. The bulkheads on the citadel were 6in, as was the steering protection.
