Panzerkampfwagen VIII Maus was a German World War II super-heavy tank completed in late 1944. It is the heaviest fully enclosed armoured fighting vehicle ever built. Only one complete prototype was built before the testing grounds were captured by the advancing Soviet forces.
That single complete prototype unit underwent trials in late 1944. It was 10.2 metres (33 ft 6 in) long, 3.71 metres (12 ft 2 in) wide and 3.63 metres (11.9 ft) tall. Weighing 200 metric tons, the Maus's main armament was a 128 mm KwK 44 gun (55 calibers long barrel), based on the 12.8 cm Pak 44 anti-tank artillery piece, with a coaxial 75 mm gun. The 128 mm gun was powerful enough to destroy all enemy armored fighting vehicles at close or middle ranges, and even some at ranges exceeding 3500 meters.[1]
The principal problem in development of the Maus was finding a powerful enough engine for its weight that could be carried in the tank. Though the design called for a maximum speed of 20 kilometres per hour (12 mph), no engine was found that could power the prototype to more than 13 kilometres per hour (8.1 mph) under ideal conditions. The weight also made it impossible to cross most bridges; it was intended to ford or submerge and use a snorkel to cross rivers.

[edit]Development
The basic design known as the VK7001/Porsche Type 205 was suggested by Ferdinand Porsche to Adolf Hitler in June 1942, who subsequently approved it. The design up to then had been the culmination of work done by Porsche who had won the contract for the heavy tank that March. Work on the design began in earnest; the first prototype, to be ready in 1943 was initially to receive the name Mammut (Mammoth). This was reportedly changed to Mäuschen (Little Mouse) in December 1942 and finally to Maus (Mouse) in February 1943, which became the most common name for this tank. Its ordnance inventory designation wasSdKfz 205.
Hitler's obsession with heavy tanks reached its zenith with the design of the Panzer VIII Maus. What is clear is that the time and energy spent on designing and producing these behemoths wasted a vast amount of precious design and production effort, which Nazi Germany could ill afford to spare. Guderian described the Maus as "this gigantic offspring of the fantasy of Hitler and his advisors."[2]
The Maus was designed from the start to use the "electric transmission" design which Ferdinand Porsche had used in his unsuccessful attempt to win the production contract for the Tiger. The initial prototypes used a gasoline engine, the later ones were to use diesel. It drove a massive electrical generator, and together they occupied the entire central rear two-thirds of the Maus' hull, cutting off the forward driver's compartment in the hull from direct access to the turret from within the tank. Each metre-wide track, which used the same basic "contact shoe" and "connector link" design format as the Henschel-built King Tigerhad used, had its own electric motor mounted in the rear of the hull; the tracks had no direct mechanical connection to the internal combustion engine that powered the Maus.
Due to the uniquely wide tracks used (1100 mm each), there was a narrow lengthwise "tunnel" inside the hull under and to the rear of the turret to house the engine and generator of the tank's powertrain.[clarification needed]
The amount of armour was substantial, the hull front was 220 millimetres (8.7 in). The sides and rear of the hull were up to 190 millimetres (7.5 in). The turret armour was even thicker, the turret front was up to 240 millimetres (9.4 in) and the sides and rear 220 millimetres (8.7 in). The mantlet was 250 millimetres (9.8 in), and combined with the turret armour behind, the protection level at that section was even higher.
The initial plan for the Maus was for the prototype to have been completed by the summer of 1943, with monthly production scheduled to run at five vehicles per month after delivery of the prototype. The work on the Maus would be divided between Krupp, responsible for the chassis, armament and turret and Alkett, who would be responsible for final assembly.
The Maus tank was originally designed to weigh approximately 100 tons and be armed with a 128 mm main gun and a 75 mm co-axial secondary gun. Additional armament options were studied including various versions of 150 mm and 128 mm guns. Hitler himself in January 1943 insisted that the armament be a 128 mm main gun with a coaxial 75 mm gun.
By May 1943, a wooden mockup of the final Maus configuration was ready and presented to Hitler, who approved it for mass production, ordering a first series of 150. At this point, the estimated weight of the Maus was 188 tons. However, there is a story that concerns the main armament of the Maus being changed by Hitler who said that the 128 mm gun looked like a ´toy gun´ when compared to the tank, causing the 128 mm to be replaced by a 150 mm gun.
In his book Panzer Leader, Heinz Guderian wrote:
On May 1 a wooden model of the "Maus", a tank project of Porsche and Krupp, was shown to Hitler. It was intended to mount a 150 mm gun. The total weight of the tank was supposed to reach 175 tons. It should be considered that after the design changes on Hitler's instructions the tank will weigh 200 tons. The model didn't have a single machine gun for close combat, and for this reason I had to reject it. It had the same design flaw that made the Elefant unsuitable for close combat. In the end, the tank will inevitably have to wage a close combat since it operates in cooperation with the infantry. An intense debate started, and except for me, all of the present found the "Maus" magnificent. It was promising to be exactly that, a "giant".[3]
Development work on the Maus continued, but in October 1943 Hitler cancelled the order, which was followed in November by the order to stop development of the Maus altogether but to continue the construction of the prototypes.
[edit]V1
The first, turretless prototype (V1) was assembled by Alkett in December 1943. Tests started the same month, with a mock turret fitted of the same weight as the real turret.
The principal problem with the Maus that emerged from this test was its power-to-weight ratio. There was no engine powerful enough to give it anything like the 20 km/h demanded by the design specifications. The modified gasoline-fuelled Daimler-Benz MB 509 engine used in the prototype was only able to move at 13 km/h and only under ideal conditions. The suspension system used by the Maus also had to be adjusted to enable it to take the tank's weight.
Another issue found was that the Maus was simply too heavy to cross bridges. As a result an alternative system was developed, where the Maus would instead ford the rivers it needed to cross. Due to its size it could ford relatively deep streams, but for deeper ones it was to submerge and drive across the river bottom. The solution required tanks to be paired up. OneMaus would supply electrical power to the crossing vehicle via a cable until it reached the other side. The crew would receive air through a large snorkel, which was long enough for the tank to go 45 feet (13 m) underwater.
[edit]V2
In March 1944 the second prototype, the V2, was delivered. It differed in many details from the V1 prototype. In mid-1944, the V2 prototype was fitted with a powerplant and the first produced Maus turret. This turret was fitted with a 128 mm KwK 44 L/55 gun, with coaxial 75 mm KwK 44 L/36.5 gun and a 7.92 mm MG34 for anti-aircraft armament. The V1 prototype was supposed to be fitted with the second produced turret, but this never happened.
By July 1944, Krupp was in the process of producing four more Maus hulls, but they were ordered to halt production and scrap these. Krupp stopped all work on it in August 1944. Meanwhile, the V2 prototype started tests in September 1944, fitted with a Daimler-Benz MB 517 diesel engine, new electric steering system and a Skoda Works designed running gear and tracks.
There was also a special railroad car made for transporting the Maus prototypes.
[edit]Flak
In the latter stages of World War II, Allied air superiority on all fronts severely hampered German forces, especially armor. Aircraft like the Ilyushin Il-2, Hawker Typhoon, and the Republic P-47 Thunderbolt wreaked havoc among the Panzer Divisions. With the late-war interest in super-heavy tank like the Maus and E-100 (and one could also include the Tiger II andJagdtiger in this category), the need for complementary air defense was clear.
Towards the end of the war, Soviet forces discovered blueprints for a turret mounting twin 8.8 cm flak guns which was to have been mounted on either the Maus or the Panzerkampfwagen E-100. Later in 1945 a mild steel mock up of the turret was reportedly discovered. Since the flak vehicle would use the same chassis as the tanks it was protecting, maintenance and spare part inventories would have been rationalized considerably.
It was envisioned that each Maus or E-100 battalion would include at least three of these vehicles. The Flakzwilling itself would be operated by a crew of eight: a driver, commander, gunner, mechanic, and four loaders for the rapid-firing flak cannons. For anti-aircraft operations, the three flak vehicles would be directed by a fourth vehicle. This command vehicle would have been equipped with a mobile range and altitude finder as well as a target tracking system. No records as to the nature of this vehicle's systems, nor what chassis it would have been constructed upon, have surfaced.
[edit]Capture
The working Maus prototypes remained at Kummersdorf and at the proving grounds in Böblingen. In the last weeks of the war the V1 with the dummy turret was captured by the advancing Soviet forces in the vicinity of the western batteries of the Kummersdorf artillery firing grounds. It had been thought to be mechanically sabotaged by the Germans before abandoning it. Some sources state that the Panzerkampfwagen VIII saw combat while defending the facility at Kummersdorf, although the popular version is that it did not.[4]
The Soviet Commander of Armored and Mechanized troops ordered the hull of V1 to be mated with the turret of V2. The Soviets used six 18t German half-tracks to pull the 55 ton turret off the burnt-out hull. The combined V1 hull/V2 turret vehicle was completed in Germany and sent back to the USSR for further testing. It arrived there on May 4, 1946. When further testing was completed the vehicle was taken over by theKubinka Tank Museum for storage where it is now on display.
It appears that the capture of this prototype had little impact on post-war Soviet tank development. Soviet tank design continued to concentrate on maneuverability by strictly limiting size and weight. The next-generation Soviet tanks had similar levels of protection and armament. The IS-3 heavy tank was armed with a 122 mm gun, but weighed under 50 tonnes. The T-54 main battle tank, which started production in 1947, provided 200 mm of frontal turret armor, 100 mm of frontal hull armor and a 100 mm main gun, while weighing in at slightly less than 40 tons.
