My current version of a 1919 British fast battleship

Continuing the current British fast battleship series is the 1919 version. The British considered 16.5in guns and I have adopted them. 16in guns were too small for that date, considering that larger guns were being actively developed. I had wanted 29 knots for this ship, but the size increase was greater than I wanted to have. I settled for a 28-knot ship with 9-16.5in BLR, 16-6in QF, 6-4.7in AA, and 36-2pdr AA guns. The armour basis is 14in. The deck is a respectable 6in. The torpedo bulkhead is a robust 4in. The hull is flush-decked and has a transom stern. This is the Springsharp report:
