The Super Lion with a 9in belt

The Super Lion works quite well with a 9in belt, still using normal weight machinery. The displacement must be greater, however. The Standard displacement is now 39,306 tons. The ship is still 812ft x 105ft x 30ft with 10-15in/42 and 14-6in QF guns with a speed of 30 knots. When you realize that the Super Lion has a heavier armament than the Hood, then you realize that the displacement needs to be quite substantial. This is the Springsharp report:
