I like this mod very much. The amount of detail and accuracy of the ships is awesome. My only complaint is the size of the budgets. The US seems fine since they cranked out ships at a huge rate during this period but Japan and to a lesser extent France and the Soviet Union seem way too high. In real 1940 Japan could barely maintain their large fleet and during the war they only produced a few carriers, a few small cruisers, and some destroyers. No battleships, heavy cruisers or nearly enough escort vessels. However with the budget currently as is, Japan can commission carriers almost on an Essex scale. I love this mod because I want to play with real WWII ships, not a whole bunch of AI ships that can be massed produced within a couple of years.
Very minor note: the Japanese Hatsuharu-class DD gun layout and image reflects the first two members of the class as originally built, but following the capsizing of the Tomozuru in 1934, these two were rebuilt and had the single 5-inch gun moved from its superfiring position on the forecastle to a position in front of the rear double turret. The remaining members of the class still building were also so modified. This profile (and gun layout) would probably serve better for 1936 start:
