A fast British 1921 light cruiser

The GB/CL/1921 "Fast" light cruiser was an attempt to see what might be achieved with Springsharp 3.0b2 Beta. This ship carried 9-6in/55 QF guns and 12-21in TT at a speed of 37 knots. It has a range of 5400nm at 15 knots. I added some protection, including a thin torpedo bulkhead. It would be heavily damaged, but might survive on torpedo. This is the Springsharp report:
