 ever built. Only two hulls and one turret were completed before the testing grounds were captured by the advancing Soviet forces.

These two prototypes (one with, one without turret) underwent trials in late 1944. The complete vehicle was 10.2 metre long, 3.71 metre 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 medium ranges, and even some at ranges exceeding 3500 meters.

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 (12.4 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

 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 was SdKfz 205.

Hitler's obsession with heavy tanks reached its zenith with the construction 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.

. 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.

 had 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.

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.

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.

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. In June 1944 the production turret, with armament, was used for tests.

The principal problem with the Maus that emerged from this test was its power-to-weight ratio

-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. One Maus 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.

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

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.
