What has to be done to put Sea Hurricane earlier in service then in OTL which was in 1941? I know that British had two seater fighter aircraft on their carriers because of real or imagined navigation issues, but what POD is neccessary to have naval variant of Hurricane on a Carrier before the beginning of WW2?
Recently I read about the British carrier aviation, and while they did had naval versions of Hurricanes and later Spitfires, and excellent Sea Fury aircraft postwar, it all seems somewhat lacking. So, how early is it possible, and what are the consequences?
