The Supermarine Spitfire is one of the most iconic aircraft of all time. Between 1937 and 1947 over 20,000 of them were built and in those 10 years, Spitfires changed dramatically from the Mk 1 to the Mk 24. More powerful engines, new wing shapes, different armaments, and more were added to the Spitfire in an attempt to maintain its edge over enemy aircraft. The Supermarine Spitfire was the only Allied frontline fighter in complete and continuous development all the way through the Second World War. IWM Duxford has Spitfires from all the way through production, in fact, there are probably more Spitfires gathered together at Duxford than anywhere else in the world. In this episode of Duxford in Depth, Graham Rodgers looks at how the Spitfire evolved by taking us through just a few of Duxford's collection of Spitfires including marks 1, 5, 9, 14, and 24.
