Talk about an ambitious design: Ger/CB/15

I was amazed to see what I had hoped to achieve with my 1915 German fast battlecruiser design. It looks tremendously over-optimistic about achievable speed: 40 knots.

The dimensions were: 900ft x 100ft x 29.7ft deep load. The displacement was 40,000 tons, full load. The form figures were: Cp=-0.54 and Cm=0.97. The hull depth was 58ft.

The armament was 6-=16.5in BLR and 12-6in QF.

The power plant was 216,000 SHP. That would provide 5.4 SHP/ton of displacement.

The weights were:

40,000 tons full load 3,620 tons fuel oil 543 tons feed water 35,837 tons standard

Hull: 12,528 tons Machinery: 7,200 tons Armament: 2,875 tons Protection: 8,974 tons Miscellaneous: 2,860 tons Auxiliary machinery: 1,400 tons

Hoped for range:

2,500 miles at 40 knots for 62.5 hours

0.616/SHP or 57.80 tons/hr.

30 SHP/ton of machinery
