This is the same Tiger tank design as before but with improved graphics and a different title font. The 2 differences in the Tiger are that I have taken out the turret hatch covers and are now closed. The Tiger differed from earlier German tanks principally in its design philosophy. Its predecessors balanced mobility, protection, and firepower. They were sometimes outgunned by their opponents. The Tiger I represented a new approach that emphasised firepower and armour at the expense of mobility. Design studies for a new heavy tank had been started in the late 1930s, without any production planning. The real impetus for the

was provided by the quality of the Soviet T-34. Although the general design and layout were broadly similar to the previous medium tank the

, the Tiger weighed more than twice as much. This was due to its substantially thicker armour, the larger main gun, and the consequently greater volume of fuel and ammunition storage, larger engine, and more solidly-built transmission and suspension. The Tiger I had frontal hull armour 100 mm thick and frontal turret armour of 110 mm, as opposed to the 80 mm frontal hull and 50 mm frontal turret armour of contemporary models of the Panzer IV. It also had 80 mm thick armour on the sides and rear. The top and bottom armour was 25 mm thick; later, the turret roof was thickened to 40 mm. Armour plates were mostly flat, with interlocking construction. The armour joints were of high quality, being stepped and welded rather than riveted. The tank was too heavy for most bridges, so it was designed to ford four-meter deep water. This required unusual mechanisms for ventilation and cooling when underwater. At least 30 minutes of setup was required, with the turret and gun being locked in the forward position, and a large snorkel tube raised at the rear. Only the first 495 units were fitted with this deep fording system; all later models were capable of fording only two meters. The rear of the tank held an engine room flanked by two floodable rear compartments each containing a fuel tank, radiator, and fans. The petrol (gasoline) engine was a 21-litre 12-cylinder Maybach HL 210 P45 with 650 PS (641 hp, 478 kW). Although a good engine, it was inadequate for the vehicle. From the 250th Tiger, it was replaced by the uprated HL 230 P45 (23 litres) of 700 PS (690 hp, 515 kW). The engine was in V-form, with two cylinder banks at 60 degrees. An inertial starter was mounted on its right side, driven via chain gears through a port in the rear wall. The engine could be lifted out through a hatch on the hull roof. The engine drove front sprockets, which were mounted quite low. The eleven-ton turret had a hydraulic motor powered by mechanical drive from the engine. A full rotation took about a minute. The suspension used sixteen torsion bars. To save space, the swing arms were leading on one side and trailing on the other. There were three road wheels on each arm, giving a good cross-country ride. The wheels had a diameter of 800 mm and were interleaved. Removing an inner wheel that had lost its tire (a common occurrence) required the removal of several outer wheels also. The wheels could become packed with mud or snow that could then freeze. Eventually, a new 'steel' wheel design. closely resembling those on the Tiger II, with an internal tire was substituted. The tracks were an unprecedented 725 mm wide. To meet rail-freight size restrictions, the outer row of wheels had to be removed and special 520 mm wide transport tracks installed. With a good crew, a track change took 20 minutes. The internal layout was typical of German tanks. Forward was an open crew compartment, with the driver and radio-operator seated at the front, either side of the gearbox. Behind them the turret floor was surrounded by panels forming a continuous level surface. This helped the loader to retrieve the ammunition, which was mostly stowed above the tracks. Two men were seated in the turret; the gunner to the left of the gun, and the commander behind him. There was also a folding seat for the loader. The turret had a full circular floor and 157 cm headroom. Turmzielfernrohr TZF 9c Tiger I in France, 1944. The gun breech and firing mechanism were derived from the famous German "88" dual purpose flak gun. The 88 mm Kwk 36 L/56 gun was the variant chosen for the Tiger and was, along with the

Kwk 43 L/71, one of the most effective and feared tank guns of World War II. The Tiger's gun had a very flat trajectory and extremely accurate Zeiss Turmzielfernrohr TZF 9b sights (later replaced by the monocular TZF 9c). In British wartime firing trials, five successive hits were scored on a 16"x18" target at a range of 1,200 yards. Tigers were reported to have knocked out enemy tanks at ranges greater than a mile (1,600 m), although most World War II engagements were fought at much closer range. Another new feature was the Maybach-Olvar hydraulically-controlled pre-selector gearbox and semi-automatic transmission. The extreme weight of the tank also required a new steering system. Instead of the clutch-and-brake designs of lighter vehicles, a variation on the British Merritt-Brown single radius system was used. The Tiger's steering system was of twin radius type, meaning that two different, fixed radii of turn could be achieved at each gear, the smallest radius on the first gear was four meters. Since the vehicle had an eight-speed gearbox, it thus had sixteen different radii of turn. If a smaller radius was needed, the tank could be turned by using brakes. The steering system was easy to use and ahead of its time. However, the tank's automotive features left much to be desired. When used to tow an immobilised Tiger, the engine often overheated and sometimes resulted in an engine breakdown or fire, so Tiger tanks were forbidden by regulations to tow crippled comrades. The low-mounted sprocket limited the obstacle-clearing height. The tracks also had a bad tendency to override the sprocket, resulting in immobilisation. If a track overrode and jammed, two Tigers were normally needed to tow the tank. The jammed track was also a big problem itself, since due to high tension, it was often impossible to disassemble the track by removing the track pins. It was sometimes simply blown apart with an explosive charge. The standard German Famo recovery tractor could not tow the tank; up to three tractors were usually needed to tow one Tiger. Although the Tiger I was one of the most heavily armed and armoured tanks of the war, and a formidable opponent of Allied tanks, the design was conservative and had some serious drawbacks. The flat armour plates were unsophisticated in comparison to the sloped armour of the Soviet T-34, requiring a massive increase in weight to provide for sufficient protection. The tank's weight put severe stress on the suspension, whose complexity made maintenance difficult. The sophisticated transmission system was also prone to breakdowns. A major problem with the Tiger was its very high production cost. During the Second World War, over 40,000 American Sherman and 58,000 Soviet T-34s were produced, compared to 1,355 Tiger I and 478 Tiger II tanks. The German designs were expensive in terms of time, raw materials and Reichsmarks, the Tiger I costing over twice as much as a contemporary Panzer IV and four times as much as a Stug III assault gun.[1][dead link] The closest counterpart to the Tiger from the United States was the M26 Pershing (around 200 deployed during the war) and IS-2 from the USSR (about 3,800 built during the war). German heavy tank of World War II. The initial official German designation was Panzerkampfwagen VI Ausfhrung H (abbreviated PzKpfw VI Ausf. H, Ausfhrung is German for "version") but the tank was re designated as Panzerkampfwagen VI Ausf. E in March 1943. The tank also had the ordnance inventory designation SdKfz 181. The Tiger I was in use from late 1942 until the German surrender in 1945. It was given its "Tiger" nickname by Ferdinand Porsche (the Roman numeral was added after the Tiger II was produced). The design served as the basis for other armoured vehicles, the Sturmtiger heavy self-propelled gun and the Bergetiger amoured recovery vehicle. Tigers were capable of destroying the American M4 Sherman or British Churchill IV at ranges exceeding 2,000 m. In contrast, the Soviet T-34 equipped with the 76.2 mm gun could not penetrate the Tiger frontally at any range, but could achieve a side penetration at approximately 500 m firing the BR-350P APCR ammunition. The T34-85's 85 mm gun could penetrate the Tiger from the side at about range 1,000 m. The IS-2's 122 mm gun could destroy the Tiger at ranges beyond 1,000 m. From a 30 degree angle of attack the M4 Sherman's 75 mm gun could not penetrate the Tiger frontally at any range, and needed to be within 100 m to achieve a side penetration against the 80mm upper hull superstructure. The British 17-pounder as used on the Sherman Firefly, firing its normal APCBC ammunition, could penetrate frontally out to over 1,000 m. The US 76 mm gun, if firing the APCBC M62 ammunition, could penetrate the Tiger frontally out to just over 500 m, and could be at ranges in excess of 1,000 m to achieve penetration against the upper hull superstructure. Using HVAP ammunition, which was in constant short supply and primarily issued to tank destroyers, frontal penetrations were possible out to just over 1,500 m. It is worth mentioning that many of the penetration capabilities at longer ranges had little relevance compared to combat engagements of the real war, especially that which was fought in Western Europe, where engagements rarely happened outside of one kilometer due to dispersion and chance for human error, which is amplified greatly as range increases regardless of the ability of any cannon. For example, while a 17pdr could penetrate the front armor of a Tiger I at one kilometer in tests, during real combat, a 17pdr gunner would probably never find himself in a position to actually attempt such a feat. As range decreases in combat, all guns can penetrate more armor (with the exception of HEAT ammunition, which was rare in World War II). The great penetrating power of the Tiger's gun meant that it could destroy many of its opponents at ranges at which they could not respond. In open terrain, this was a major tactical advantage. Opposing tanks were often forced to make a flanking attack in order to knock out a Tiger. The Tiger was first used in action in September 1942 near Leningrad. Under pressure from Hitler, the tank was put into action months earlier than planned and many early models proved to be mechanically fragile. In its first action on 23 September 1942, many of the first Tigers broke down. Others were knocked out by dug-in Soviet anti-tank guns. One tank was captured largely intact, which gave the Soviets a chance to study the tank and prepare a response. In the Tiger's first actions in North Africa, the tank was able to dominate Allied tanks in the wide-open terrain. However, mechanical failures meant that there were rarely more than a few in action. In a replay of the Leningrad experience, at least one Tiger was knocked out by towed British six-pounder antitank guns. The tank's extreme weight limited the bridges it could cross and made drive-throughs of buildings, which may have had basements, risky. Another weakness was the slow traverse of the hydraulically-operated turret. The turret could also be traversed manually, but this option was rarely used, except probably for a fix of a few mils. Early Tigers had a top speed of about 45 km/h over optimal terrain. This was not recommended for normal operation, and was discouraged in training. Crews were told to not exceed 2600RPM due to reliability problems of the early Maybach engines at their maximum 3000RPM output. To combat this, the Tiger's top speed was reduced to about 38km/h through the installation of an engine governor, capping the RPM of the Maybach HL 230 to 2600rpm (HL 210s were used on early models). Despite being slower than medium tanks of the time, which averaged a top speed of about 45 km/h, the Tiger still had a very respectable speed for a tank of its size and weight, being nearly twice as heavy as a Sherman or T-34. The Tiger had reliability problems throughout its service life; Tiger units frequently entered combat understrength due to breakdowns. It was rare for any Tiger unit to complete a road march without losing vehicles due to breakdown. The tank also had poor radius of action (distance a combat vehicle can travel and return, in normal battle conditions, without refueling). Due to its very wide tracks, the Tiger had a lower ground pressure bearing than many smaller tanks, the most notable exception being the Soviet T-34. The Tiger's armor and firepower, however, were feared by all its opponents. In tactical defense, its poor mobility was less of an issue. Whereas Panthers were the more serious threat to Allied tanks, Tigers had a bigger psychological effect on opposing crews, causing a "Tiger phobia". Allied tankers would sometimes evade rather than confront a Tiger, even a tank that only looked like one, such as the Panzer IV with turret skirts applied. In the Normandy campaign, it could take four to five Shermans to knock out a single Tiger tank by maneuvering to its weaker flank or rear armour; the Soviet T-34s fared similarly against the German tanks, as had the German Panzer III earlier against the Soviet heavy tanks. An accepted Allied tactic was to engage the Tiger as a group, one attracting the attention of the Tiger crew while the others attacked the sides or rear of the vehicle. Since the ammunition and fuel were stored in the sponsons, a side penetration often resulted in a kill. This was a risky tactic, and often resulted in the loss of several Allied vehicles. It took a great deal of tactical skill to eliminate a Tiger. Tigers were usually employed in separate heavy tank battalions (schwere-Panzer-Abteilung) under army command. These battalions would be deployed to critical sectors, either for breakthrough operations or, more typically, counterattacks. A few favored divisions, such as the Grossdeutschland or some of the low-numbered Waffen-SS divisions had a handful of Tigers. The Tiger was originally designed to be offensive breakthrough weapon but by the time they came into action, the military situation had changed dramatically, and their main use was on the defensive as mobile gun batteries. [3] Unfortunately this also meant rushing the Tigers constantly from location to location causing excessive mechanical issues. As a result there are almost no instances where a Tiger Batallion went into combat at anything close to full strength. Furthermore, against the Soviet and Western Allied production numbers, even a 10:1 kill ratio would not have been sufficient for the Tigers. Some Tiger units did exceed the 10:1 kill ratio, including 13. Kompanie/Panzer-Regiment Grossdeutschland (16.67:1), schwere SS-Panzer-Abteilung 103 (12.82:1) and schwere Panzer-Abteilung 502 (13.08:1). These numbers must be set against the opportunity cost of building the expensive Tiger. Every Tiger built cost as much as four Sturmgeschütz III assault guns. On 7 July 1943, a single Tiger tank commanded by SS-Oberscharführer Franz Staudegger from the 2nd Platoon of 13th Panzer Company of 1st SS Division Leibstandarte SS Adolf Hitler engaged a group of about 50 T-34s around Psyolknee (the southern sector of the German salient in the Battle of Kursk). Staudegger used all his ammunition in destroying 22 Soviet tanks, while the rest retreated. For this, Staudegger was awarded the Knight's Cross. On 8 August 1944, a single Tiger commanded by SS-Unterscharführer Willi Fey from the 1st Company of sSSPzAbt 102, engaged a British tank column, destroying some 14 out of 15 Shermans, followed by one more later in the day using his last two rounds of ammunition. sSSPzAbt 102 lost all of its Tigers during fighting in Normandy, but reported 227 Allied tanks destroyed in six weeks. The Tiger is particularly associated with SS-Haupsturmfurher Michael Wittmann of schwere SS-Panzerabteilung 101. He worked his way up, commanding various vehicles and finally a Tiger I. In the Battle of Villers-Bocage, he destroyed over two dozen Allied vehicles including several tanks; and single-handedly held up the advance of the entire 7th Armored Division until his tank was knocked out and abandoned. Over 10 Tiger tank commanders had over 100 vehicle kills on their account, including: Kurt Knispel with 168 kills, Otto Carius with 150+ kills, Johannes Boumllter with 139+ kills, and Michael Wittmann with 138 kills.
