Tiger I is the common name of a German heavy tank of World War II. The Tiger I was in use from late 1942 until the German surrender in 1945. It was given its "Tiger" nickname by Ferdinand Porsche (the Roman numeral was added after the Tiger II was produced). The design served as the basis for other armoured vehicles, the Sturmtiger heavy self-propelled gun and the Bergetiger amoured recovery vehicle.
