Very fast is relative: the GB/CB/1921 Very Fast with 9-12in guns

This is not as fast as my last attempt at a fast battlecruiser. This version is "just 35 knots". The main features are that the armament is just 9-12in guns and the displacement is much less. The Standard displacement is only 29,198 tons. The secondary armament is 12-5.5in QF guns. The belt is 7in with a 3in deck. This is the Springsharp report:
