Development

Development of a heavy tank design had been initiated in 1937; the initial design contract was awarded to
Henschel Henschel & Son (german: Henschel und Sohn) was a German company, located in Kassel, best known during the 20th century as a maker of transportation equipment, including locomotives, trucks, buses and trolleybuses, and armoured fighting v ...

; the main differences were in the hull, transmission, suspension and automotive features. The Henschel version used a conventional hull design with sloped armour resembling the layout of the Panther tank. It had a rear-mounted engine and used nine steel-tired, eighty-centimeter-diameter overlapping road wheels per side with internal springing, mounted on transverse torsion bars, in a similar manner to the original Henschel-designed Tiger I. To simplify maintenance, however, as when the same steel-tired road wheels were used on later Tiger I hulls, the wheels were only overlapping ''without'' being interleaved—the full ''Schachtellaufwerk'' rubber-rimmed road-wheel system that had been in use on nearly all German half-tracks used the interleaved design, later inherited by the early production versions of the Tiger I and Panther. 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 drive (fundamentally identical to a Diesel-electric transmission, only using a gasoline-fueled engine as the

Design

Henschel won the design contract, and all Tiger IIs were produced by the firm. Two turret designs were used in production vehicles. The initial design is often misleadingly called the "Porsche" turret due to the misbelief that it was designed by Porsche for their Tiger II prototype; in fact it was the initial Krupp design for both prototypes. This turret had a rounded front and steeply sloped sides, with a difficult-to-manufacture curved bulge on the turret's left side to accommodate the commander's cupola. Fifty early turrets were mounted to Henschel hulls and used in action. In December 1943 the more common "production" turret, sometimes erroneously called the "Henschel" turret, was simplified with a significantly thicker flat face (which eliminated the shot trap caused by the curved face of the earlier turret), and less-steeply sloped sides, which avoided the need for a bulge for the commander's cupola, and added additional room for ammunition storage. The turrets were designed to mount the

L/71 gun. Combined with the ''Turmzielfernrohr'' 9d (German "turret telescopic sight") monocular sight by Leitz, which all but a few early Tiger IIs used, it was a very accurate and deadly weapon. During practice, the estimated probability of a first-round hit on a high, wide target was 100 percent at , 95–97 percent at and 85–87 percent at , depending on ammunition type. Recorded combat performance was lower, but still over 80 percent at 1,000 m, in the 60s at 1,500 m and the 40s at 2,000 m. Penetration of armoured plate inclined at 30 degrees was at and respectively for the ''Panzergranate'' 39/43 projectile (PzGr –

), and for the PzGr. 40/43 projectile between the same ranges. The ''Sprenggranate'' 43 (SpGr) high-explosive round was available for soft targets, or the ''Hohlgranate'' or ''Hohlgeschoss'' 39 (HlGr – HEAT or High-explosive anti-tank warhead) round, which had penetration at any range, could be used as a dual-purpose munition against soft or armoured targets.Jentz and Doyle 1993, pp. 23–24 Powered turret traverse was provided by the variable speed Boehringer-Sturm L4S hydraulic motor, which was driven from the main engine by a secondary drive shaft. A high and a low speed setting was available to the gunner via a lever on his right. The turret could be rotated 360 degrees at 6º/second in low gear independent of engine rpm, at 19º/second – the same as with the Tiger I – with the high speed setting and engine at 2000 rpm, and over 36º/second at the maximum allowable engine speed of 3000 rpm. The direction and speed of traverse was controlled by the gunner through pedals, or a control lever near his left arm. This system allowed for very precise control of powered traverse, a light touch on the pedal resulting in a minimum traverse speed of 0.1 deg/sec (360 degrees in 60 min), unlike in most other tanks of the time (e.g. US

) this allowed for fine laying of the gun without the gunner needing to use his traverse handwheel. If power was lost, such as when the tank ran out of fuel, the turret could be slowly traversed by hand, assisted by the loader who had an additional wheel, which could manually rotate the turret at a rate of one-half a degree per each revolution of the hand crank; a 20° turret rotation required 40 full cranks of the handwheel, and to turn the turret a full 360° the gunner would be required to crank the handwheel 720 full revolutions.

tanks. The Tiger II was under-powered, like many other heavy tanks of World War II, and consumed a lot of fuel, which was in short supply for the Germans. The transmission was the Maybach OLVAR OG 40 12 16 Model B, giving eight forward gears and four reverse, which drove the steering gear. This was the Henschel L 801, a double radius design which proved susceptible to failure. Transverse torsion bar suspension supported the hull on nine axles per side. Overlapped diameter road wheels with rubber cushions and steel tyres rode inside the tracks.Jentz and Doyle 1993, pp. 11–12. Like the Tiger I, each tank was issued with two sets of tracks: a normal "battle track" and a narrower "transport" version used during rail movement. The transport tracks reduced the overall width of the load and could be used to drive the tank short distances on firm ground. The crew were expected to change to normal battle tracks as soon as the tank was unloaded. Ground pressure was 0.76 kg/cm2 (10.8 psi).


Command variant

The command variant of the Tiger II was designated ''Panzerbefehlswagen'' Tiger ''Ausf. B''. It had two versions, ''Sd.Kfz''. 267 and ''Sd.Kfz''. 268. These carried only 63 rounds of 8.8 cm ammunition to provide room to accommodate the extra radios and equipment, and had additional armour on the engine compartment. The ''Sd.Kfz''. 267 was to have used ''FuG'' 8 and ''FuG'' 5 radio sets, with the most notable external changes being a rod antenna mounted on the turret roof and a ''Sternantenne D'' ("Star antenna D"), mounted on an insulated base (the 105 mm ''Antennenfuß Nr. 1''), which was protected by a large armoured cylinder. This equipment was located on the rear decking in a position originally used for deep-wading equipment. The ''Sd.Kfz''. 268 used ''FuG'' 7 and ''FuG'' 5 radios with a two-metre rod antenna mounted on the turret roof and a 1.4 metre rod antenna mounted on the rear deck.


Production

The Tiger II was developed late in the war and built in relatively small numbers. Orders were placed for 1,500 Tiger IIs—slightly more than the 1,347

tanks produced—but production was severely disrupted by Allied bombing raids.Manchester 1968, p. 498. Among others, five raids between 22 September and 7 October 1944 destroyed 95 percent of the floor area of the Henschel plant. It is estimated that this caused the loss in production of some 657 Tiger IIs.Jentz and Doyle 1993, p. 17. Only 492 units were produced: one in 1943, 379 in 1944, and 112 in 1945. Full production ran from mid-1944 to the end of the war.Jentz 1996, p. 288. Each Tiger II produced needed 300,000 man hours to manufacture and cost over 800,000 Reichsmark or US$300,000 () per vehicle. The vehicle was the costliest German tank to produce at the time. The Tiger II served as the basis for one production variant, the ''

Reliability and mobility

Early Tiger IIs proved unreliable, owing principally to leaking seals and gaskets, and an overburdened drive train originally intended for a lighter vehicle.Jentz and Doyle 1993, p. 34 The double radius steering gear was initially particularly prone to failure.Jentz and Doyle 1993, p. 11 Lack of crew training could amplify this problem; drivers originally given only limited training on other tanks were often sent directly to operational units already on their way to the front. The ''Schwere Heeres Panzer Abteilung'' 501 (s.H.Pz.Abt. 501) arrived on the Eastern Front with only eight out of 45 tanks operational; these faults were mostly due to drive-train failures. The first five Tiger IIs delivered to the Panzer Lehr Division broke down before they could be used in combat, and were destroyed to prevent capture.Jentz and Doyle 1993, p. 35. The sPzAbt 503 noted in Combat Report in Hungary, October 1944: The introduction of modified seals, gaskets and drive train components, as well as improved driver training and sufficient maintenance improved the tank's mechanical reliability. Statistics from 15 March 1945 show reliability rates of 59 percent for the Tiger, almost equal to the 62 percent of the

Because these German tanks suffered ammunition explosions, which caused many crew fatalities, main gun rounds were no longer allowed to be stowed within the turret, reducing capacity to 68. Up to fourteen Tiger IIs of the 501st were destroyed or captured in the area between 11 and 14 August to ambushes and flank attacks by both Soviet T-34-85 and IS-2 tanks, and ISU-122 assault guns in inconvenient sandy terrain.

models, neither the British nor US forces brought heavy tanks into service. A ''Wa Prüf 1'' report estimated that the Tiger II's frontal aspect was impervious to the Soviet 122 mm D-25T, the largest calibre tank gun of the war. However, Soviet testing contradicted this as they found that the frontal glacis could be destroyed by firing 3–4 shots at the weld joints from the ranges of 500–600m which were found to be inferior in quality to that of previous German designs like the Tiger I or Panther. An R.A.C 3.d. document of February 1945 estimated that the British (76.2 mm) QF 17-pounder gun, using

shot was theoretically capable of penetrating the front of the Tiger II's turret and nose (lower front hull) at respectively although, given the lack of a stated angle, this was presumably at the ideal 90 degrees and in combat the Tiger II was never penetrated frontally by the QF 17-Pounder.Jentz and Doyle, 1993, pp. 34–36 As a result of its thick frontal armour, flanking manoeuvres were most often used against the Tiger II to attempt a shot at the thinner side and rear armour, giving a tactical advantage to the Tiger II in most engagements.Jarymowycz 2001, p. 274. Moreover, the main armament of the Tiger II was capable of knocking out any Allied tank frontally at ranges exceeding , well beyond the effective range of Allied tank guns.Jarymowycz 2001, p. 258.

, and were soon moved to the testing grounds at Kubinka. During the transfer, the two tanks suffered from various mechanical breakdowns; the cooling system was insufficient for the excessively hot weather, where the engine tended to overheat and cause a consequential failure of the gearbox. The right suspension of one of the tanks had to be completely replaced, and its full functionality could not be re-established. The tank broke down again every 10–15 km. The

gave positive results in penetration and accuracy, which were on par with the 122 mm D-25T. It proved capable of passing completely through its "colleague", a Tiger Ausf B's turret at a range of 400 m. The armour of one vehicle was tested by firing at it with shells between 100 and 152 mm calibre. The welding was, despite careful workmanship, significantly worse than on similar designs. As a result, even when shells did not penetrate the armour, there was often a large amount of

from the inside of the plates, which damaged the transmission and rendered the tank inoperable. Further testing showed that the armour plate itself exhibited deficiencies in quality compared to earlier German tanks such as the Tiger I and Panther. Lab testing found that the armour plates lacked molybdenum (ascribed to a loss of supply, being replaced by vanadium), resulting in low malleability. The expanded firing test states that the АР projectiles from the 100 mm BS-3 and 122 mm A-19 gun penetrated a Tiger Ausf B's turret at ranges of 1000–1500 metres, which suggests a quality factor of 0.86 for the Tiger Ausf B's turret. The firing test against the Tiger B turret front, however, was conducted after removal of the gun and mantlet, and resulted in penetrations close to armour openings, such as vision slits and gun location. The penetrations to the right gun opening were influenced by previous 100 mm projectile penetration hits or armour damage. The 100 mm BS-3 and 122 mm A-19 could also penetrate the weld joints of the front hull at ranges of 500–600 metres after 3–4 shots.
