The Macchi C.205 (also known as MC.205, "MC" standing for "Macchi Castoldi") Veltro (Italian: Greyhound) was an Italian World War II fighter aircraft built by the Aeronautica Macchi. Along with the Reggiane Re.2005 and Fiat G.55, the Macchi C.205 was one of the three "Serie 5" Italian fighters built around the powerful Daimler-Benz DB 605 engine. The C.205 was a development of the earlier C.202 Folgore. With a top speed of some 400 mph and equipped with a pair of 20 mm cannon as well as 12.7 mm Breda machine guns, the Macchi C.205 Veltro was highly respected by Allied and Luftwaffe pilots alike. Regarded as the best Italian aircraft of World War II , in action it proved to be extremely effective, destroying a large number of Allied bombers and capable of successfully clashing on equal terms with such renowned fighters as the North American P-51D Mustang, a capability which encouraged the Luftwaffe to use a number of these aircraft to equip one Gruppe.
However, while the C.205 was able to match the best Allied opponents in speed and maneuverability, it was introduced late in the conflict. Moreover, due to the poor Italian industrial capability of the time, only a small production run was delivered before the end of the war. Like the Spitfire, the Veltro was tricky (in its construction) and thus slow to build. Italy's highest scoring ace, Adriano Visconti, achieved 11 of his 26 credited victories in the few weeks he was able to fly the Veltro, with the top scoring 205 Sergente Maggiore pilota Luigi Gorrini shooting down 14 enemy aircraft plus six damaged with the C.205.
