Fisher's "Perfection" armored cruiser from 1902

Mr. William H. Gard did the design work for Admiral Fisher for a fast armored cruiser in 1902. John Roberts writes about it in Battlecruisers. I did a Springsharp report for a ship similar to the Perfection:

• 540ft x 76ft x 26ft
• 25 knots maximum, 15 knots cruising speed
• 4-9.2in, 12-7.5in, and 16-4in QF guns
• 6in belt
• 6in 9.2in gun turrets
• 4in 7.5in gun turrets
• the QF guns in the superstructure protected by 2in armor
• 2.5in deck armor
• 1in anti-torpedo bulkhead
• range 6,000 nm

This is the Springsharp report:
