One of the more interesting and often overlooked aspects of the air war is the generation of aircraft that directly preceded those that we know from the war. I'm speaking of those introduced during the 30s, a time where aircraft design advanced so quickly that those that were excellent designs in the late 30s were considered obsolete by the time the war broke out. Some of these continued to have illustrious careers despite being considered dated such as the F4F and Hurricane, but most have been relegated to mediocrity and irrelevance in the pages of history. Personally, I'm quite interested in this era, as this really set the stage for what we would see mass produced only a few years later. What do you think was the best fighter design of the 1930s, and why? I would say the peak of 1930s fighter design would consist of the Soviet I-16, Dutch D.XXI, British Hurricane and Gladiator, German 109B and D, American F2A, F4F, P-35 and P-36, and French M.S. 406. Personally, I choose the P-36, as it was exceptionally good handling and reasonably durable (lacking SS tanks but that was standard for the time).
