Supermarine Spitfire
The Supermarine Spitfire was no doubt one of the very best British warplanes, and a large roleplayer of WWII. It had great speed, agility and weaponry. Over time, the Spitfire evolved into an even better aircraft. This is all a pilot could ask for. It had very few flaws, the main being that the engine would usually stall when entering a dive or when experiencing negative pressure/G-Forces due to its float carburetor engine.
