An alternative design for the GB/CB/1905 battlecruisers

This would have been a good alternative design for the GB/CB/1905 battlecruisers. I had proposed this, but my friend Cliff had opted for the 4-gun ship, instead, with lighter armor. He wanted to produce a radical ship that might make very high speeds by forcing the engineering plant. This version has 6-12in and 9-6in QF guns. Two twin turrets are forward, with one superfiring, and one is far aft. One 6in gun is superfiring over the aft 12in turret. The machinery is protected by a 6in belt, while the magazines have 4in side armor. The turrets have 10in faces while the barbettes are 8in. The speed is designed for 33 knots, although this requires light weight machinery. This is the Springsharp report:
