Considered by many to be the ultimate Spitfire, the F Mk.22 shared only a very passing resemblance to its early Spitfire ancestors. Equipped with a more powerful Griffon engine as well as a larger tail unit and cut-down rear fuselage, the F Mk.22 was the most powerful Spitfire to see service, as well as the most capable. Serving in only small numbers and too late for the Second World War, the F Mk.22 was the penultimate land based variant of the classic Spitfire design.
