I am writing an alternate history timeline where World War II has not yet happened. There is a PoD for the American Civil War, but history mostly stays the same outside of America until the 1890s and especially World War I and its aftermath. Germany wins the war and forces France to hand over Indochina, French Polynesia, French India, Madagascar, and southern French Equatorial Africa. Basically France loses all its holdings in the Pacific and Indian Oceans. The UK also gives up a few African holdings as well but otherwise is mostly intact. Austria-Hungary gains Muscat-Oman, Bahrain, Qatar, French, Italian, and British Somaliland, and Malta. The Ottomans get back Libya and Egypt. There is likely nothing like the Washington Naval Treaty after the war and if there is it gives the UK only a slight edge over Germany. I can put up a map and also a list of national territories once I am at my computer where I have all the information thus far.

I was wondering how this timeline would impact naval building patterns and doctrine, particularly with respect to the role of battleships and aircraft carriers. I was thinking that the last battleships would be completed in the late 1940s, as the momentum was swinging against them but they had not been proven obsoletr in real combat by the 1930s. Also, how does the cruiser and other large ships evolve without tonnage limits?

I was also wondering how land combat would be impacted such as the motorization/mechanization of infantry units and the role of tanks and other armored vehicles in warfare, as well as the standard service weapon (perhaps SMGs for motorized units if they exist since the assault rifle is not around).

Lastly, what does air combat look like? Are there jet combat aircraft in service, and what kind of combat doctrine exists for bombers, CAS, and interception (does ground control intercept come into being like in the real life 1950?). I was thinking most aircraft would be powerful props like Bearcats and the B-36, with jets just entering service.
