The Panzerjäger Tiger(P) (Sd.Kfz. 184), initially named Ferdinand and later upgraded as the Elefant, was a heavy German tank destroyer constructed using 90 unused Tiger (P) heavy tank chassis produced by Ferdinand Porsche. Designed by Alkett and assembled at Nibelungenwerke in early 1943, the 65-to-70-ton armored behemoth featured an extraordinary 200 mm front armor plate and was armed with the formidable 88 mm PaK 43/2 L/71 gun, capable of destroying any Allied tank well beyond their effective firing ranges. Driven by twin Maybach HL 120 engines paired with a novel but prone-to-failure gas-electric transmission system, the vehicle suffered from poor mobility, high fuel consumption, and a top speed of just 20 km/h. First deployed at the Battle of Kursk with the 656th Heavy Panzerjäger Regiment, the Ferdinand accounted for numerous Soviet tanks but suffered heavy losses due to mechanical breakdowns, minefields, and infantry flank attacks in close-quarters combat. Following Kursk, 48 surviving vehicles were refitted in late 1943 with added frontal armor, Zimmerit anti-magnetic coating, a ball-mounted MG 34 machine gun in the lower hull for infantry defense, and commander cupolas, officially being renamed Elefant. Renamed units subsequently served in Italy, the Eastern Front, and the final defense of Germany until the end of World War II.
