The Jagdtiger ("Hunting Tiger"; officially designated Panzerjäger Tiger Ausf. B) is a German casemate-type heavy tank destroyer (Jagdpanzer) of World War II. It was built upon the slightly lengthened chassis of a Tiger II. Its ordnance inventory designation was Sd.Kfz. 186.
The 72-tonne Jagdtiger was the heaviest armored fighting vehicle (AFV) used operationally by any nation in WWII and the heaviest combat vehicle of any type to be produced during the conflict. It was armed with a 12.8 cm Pak 44 L/55 main gun which could out-range and defeat any AFV fielded by the Allied forces.
It saw brief service in small numbers from late 1944 until the end of the war on both the Western and Eastern Front. Although 150 were ordered, only around 80 were produced. Due to an excessive weight and an underpowered drivetrain system, the Jagdtiger was plagued with mobility and mechanical problems. While on some occasions the Jagdtiger managed to destroy a number of Allied tanks over long distances from good ambush positions, the effort to produce and maintain them and their mechanical breakdowns made them a costly overall failure. Three Jagdtigers survive in museums.
