You are right on Nelson and Rodney. I left out all ships and designs created because of the treaty. This eliminates the Nelsons, all treaty cruisers, and the carrier conversions.
I was curious. The British and US Navy both realised the need (in the twenties) for a large cruiser force. (Battleships can't be everywhere.)
Reasons given:
1) Scouting force for fleet.
2) Trade protection. (versus surface raiders.)
3) Trade interdiction.
4) Force projection in narrow/restricted seas, where BB's where too vulnerable to TB's and mines to risk.
5) Force projection in periphery theatres.
The British estimated that they needed 75+ cruisers to meet their wartime needs.
Now, I say all this because the perceived need for cruisers would not have changed. (The Washington treaty of 1922 merely restricted non-battleship tonnage to 10,000 tons and under, with a max gun calibre size of 8 inches. The London Naval Treaty of 1930 dealt more specifically with cruisers.)
So my question is: Since one of the main premise of the game is that the Washington Naval treaty never got ratified,
and since you included the ships that were ordered, but cancelled, does this include new (cancelled IRL) cruiser construction post WW1?
My apologies if this has been covered in a previous thread.
I would expect that cruiser tonnage may well have creeped up, much like battleship tonnage did the previous decades, to enable those ships to have greater speed and endurance.
For example: The US Baltimore class, the first heavy cruiser designed that was not restriceted by treaty tonnage: Displacement: 14,472. Speed; 33 Knots. range: 10,000 nautical miles at 15 knots. Crew 1800 to 2039. Armament: Nine 8-inch guns in triple turrets. twelve 5-inch guns. Forty eight 40mm AA Guns. 4 Aircraft.
