The German L20e battleship design

The next ship that I designed from Deutsche Grosskampschiffe 1915-1918 was the L20e battleship. the L20e has dimensions 778ft x 105ft x 29.5ft. The armament is 8-16.5in BLR, 12-5.9in QF, and 8-88mm AA guns. The speed is 25 knots with a cruising speed of 13 knots for 10,500 nm. The belt is 13.8in maximum with a 1.97in armoured deck. The torpedo bulkhead is 2.36in. This is the Springsharp report:
