I got to thinking about this after starting the British victory in the Indian Ocean thread.
How could you get a better Fleet Air Arm withought butterflying away events like the Washington naval treaty or the continued existence of the RAF?
My take on this is, the OTL inskip award takes place 4 years earlier in 1933, leading to the RN gaining complete control of the FAA in 1935 not 1939. Now I dont see the actual quantity or quality of Carriers being that different than OTL as rearmanment would take place at the same pace but, with the Navy in full control Tactics would be more developed and better aircraft should be the result (with the RAF in control the FAA came bottom with regards to priority for production and design).
I see by 1939 the following aircraft in service Sea Hurricane 1 as the standard fighter, Sea Henleys as a combined Dive Bomber/Fighter not to sure about torpedo bombers could henleys carry a torpedo?
How would this affect the war particularly the Norwegian Campaign and is it realistic?
Also would the Navy have improved AA defences if this was the case?
