The PanzerjÌ_ÌÇ_ger Tiger (P) Elefant (German "elephant"; model number Sd.Kfz. 184) was a "Schwerer PanzerjÌ_ÌÇ_ger" (heavy tank destroyer) of the German Wehrmacht in World War II. They were originally built under the name Ferdinand, after their designer, Ferdinand Porsche. The design evolved from cruder, improvised designs of 1941Ì_åÇÌ_åå42, as well as the later, but still defective, Marder designs. The chassis was created from the 90 Porsche Tiger I models already built with new tracks and an all-steel wheel arrangement.
