The Elefant (German for "elephant") was a Schwerer Panzerjäger ("heavy tank-hunter"), a tank destroyer of the German Wehrmacht during World War II. It was built in small numbers in 1943 under the name Ferdinand, after its designer Ferdinand Porsche using tank hulls that had been produced for a cancelled German heavy tank design. In 1944, after modification of the existing vehicles, they were renamed Elefant. (courtesy of Wikipedia)
