Continuing a decade a day, we move on the early Inter War Years. If you want to chime in on the 1910's, that discussion is here: TMP link
This is a tough period to judge, as a lot of the aircraft used in combat were left overs from the First World War. Still, there were strides and developments during this period and a lot of experimentation that would lead to later decade craft.
What is your favorite fighter aircraft of the decade 1920-1929? Can be from any theater or country. There is no wrong or right answer. This is purely an excuse to talk up the greatest fighters of the 20th Century one decade at a time.
The aircraft should be operational within the time span, so an aircraft designed during WWI that is still flying in combat is an acceptable answer.
This decade is a real toss up to me. Many countries were experimenting and there are some really interesting designs during this period that were never put to the test. The British and French were really prolific in the 20s and I almost went with a British fighter, but have to go with what I know since this is the period where I admit my knowledge is the lowest. I was torn between a couple of aircraft but ultimately went with the Curtis P6 Hawk. It just squeaks out the decade having gone operational in 1929 and is both a very lovely aircraft (with those beautiful spats) and a great performer. To me one of the ultimate expressions of the classic biplane fighter with twin .30 machine guns, it was rugged, maneuverable and a great aircraft. (I really did give Gloster and Fairey a strong look, but they might make a come back in the next decade).
What is your favorite fighter of this decade and why?
