Here are some brief notes for me.

I'll commence drawing soon (when I learn what size canvas).
Battleship notes

1 Wyoming - basic saw action end of WWI also; dreadnought era
2 Nevada - first standard type battleships; all or nothing armor; four turret gun arrangement
3 Tennessee - post Jutland; same design; better underwater hull protection
4 Iowa - fast battleships; speed and anti air

1 Queen Elizabeth - considered first fast battleships
2 Revenge - also used WWI
3 King George V - Built with the expiration of Washington and London Treaties
GER
1 Deutschland - made obselete before completion with the launching of the HMS Dreadnought
2 Bismark - supposed super ship in class, largest in Europe but sunk by combination of Battleships cruisers and outdated torpedo bombers. Put to death the notion that the future of navies was in large battleships
