Which country had the best fighter planes in WWII?
Who had the most effective fighter plane in WW2? The German Messerschmidt Bf-109 is a great candidate for most effective fighter of WWII. Over 30,000 were built, it was flown in every theatre of the war, there were over 100 German aces with 100+ kills, and it claimed around 15,000 kills total during that war. Used to be that the German Messerschmitt was the most feared fighter plane in WW2. But then in 1943, the US came up with the Mustang – a plane very capable of taking on the Messerschmitt.
