The design followed the same concept as the Tiger I, but was intended to be even more formidable. The Tiger II combined the thick armor of the Tiger I with the sloped armor used on the Panther medium tank. The tank weighed almost seventy metric tons, was protected by 100 to 180 mm (3.9 to 7.1 in) of armor to the front, and was armed with the long barrelled 8.8 cm Kampfwagenkanone 43 L/71 gun.[notes 2] The chassis was also the basis for the Jagdtiger turretless tank destroyer.
The Tiger II was issued to heavy tank battalions of the Army (Schwere Heeres Panzer Abteilung - abbreviated s.H.Pz.Abt) and the Waffen-SS (s.SS.Pz.Abt). It was first used in combat with s.H.Pz.Abt. 503 during the Normandy campaign on 11 July 1944; on the Eastern Front the first unit to be outfitted with Tiger IIs was s.H.Pz.Abt. 501 which by 1 September 1944 listed 25 Tiger IIs operational.
Development of a heavy tank design had been initiated in 1937; the initial design contract was awarded to Henschel. Another contract followed in 1939, and was given to Porsche. Both prototype series used the same turret design from Krupp; the main differences were in the hull, transmission, suspension and automotive features.
The Henschel version used a conventional hull design with sloped armor resembling the layout of the Panther tank. It had a rear mounted engine and used nine steel-tired overlapping road wheels with internal springing per side, mounted on transverse torsion bars, in a similar manner to the original Tiger. To simplify maintenance, however, the wheels were overlapping rather than interleaved as in the Tiger I.
The Porsche hull designs included a rear-mounted turret and a mid-mounted engine. The suspension was the same as on the Elefant tank destroyer. This had six road wheels per side mounted in paired bogies sprung with short longitudinal torsion bars that were integral to the wheel pair; this saved internal space and facilitated repairs. One Porsche version had a gasoline-electric hybrid power system; two separate drive trains in parallel, one per side of the tank, each consisting of a hybrid drive train; gasoline engine – electric generator – electric motor – drive sprocket. This method of propulsion had been attempted before on the Tiger (P) (later Elefant prototypes) and in some U.S. designs, but had never been put into production. The Porsche suspension were later used on a few of the later Jagdtiger tank hunters. Another proposal was to use hydraulic drives. Dr. Porsche's unorthodox designs gathered little favor.
