During World War II, Nazi Germany was obsessed with creating advanced weapons to dominate the battlefield. Among these ambitious projects was the idea of building the largest tank ever conceived, known as the “Ratte.” This tank was part of Hitler’s vision of “Wunderwaffen,” or “wonder weapons,” which were meant to showcase Germany’s military might. While some of these projects succeeded, others, like the Ratte, never made it past the design stage.
Hitler’s army primarily fought on land, and they wanted a tank that could easily overpower their enemies. The Ratte was designed to be enormous, dwarfing all other tanks of the time. Adolf Hitler was fascinated by powerful weapons, and when he was introduced to the idea of the Ratte in 1942, he was thrilled. The design was presented by Edward Grata, a director at the Krupp company, and it aligned perfectly with Hitler’s vision of a formidable German army.
The Ratte was part of a concept known as a land battleship, an idea that had been explored since the 1930s. The Soviet Union had previously worked on a similar project, the TG-5, which inspired Grata’s design. The Ratte was planned to weigh an astonishing 1,000 metric tons, with dimensions comparable to a small building. It was to be 115 feet long, 46 feet wide, and 36 feet tall, requiring a crew of 41 men to operate.
The Ratte’s armament was as impressive as its size. It was to be equipped with two massive 28-centimeter naval guns, capable of hitting targets up to 25.6 miles away. Additional weapons included anti-tank guns and anti-aircraft guns. To move this behemoth, the Ratte needed powerful engines, with options including two MAN V12 diesel engines or eight Daimler-Benz engines, providing up to 16,000 horsepower. Despite this power, the tank’s speed was projected to be only 25 miles per hour, and even that was optimistic.
While the Ratte was an impressive concept, its size was also its downfall. No factory in Germany was large enough to build it, and even if it were constructed, transporting it to battlefields would have been nearly impossible. Its massive weight would have destroyed roads and bridges, and it would have been an easy target for Allied bombers due to its slow speed and large size. The logistical challenges and resource demands made the Ratte an impractical weapon.
In the end, the Ratte was never built. The project was canceled in early 1943 by Albert Speer, the Minister of Armaments, as Germany’s resources were already stretched thin by the war. The Ratte remained a grand fantasy, a testament to the extremes of Hitler’s ambitions. As German General Heinz Guderian noted, it was a product of Hitler’s fascination with the gigantic, but ultimately, it was a weapon that could never have been effectively used in battle.

In the years leading up to World War II, Nazi Germany conducted numerous projects aimed at developing new types of weapons to achieve military supremacy over other nations. Many of these designs were true innovations in the field of weaponry, ahead of their time. The Germans referred to them as “Wunderwaffen,” which translates to “wonder weapons” or “miracle weapons.” Some of these were successfully deployed on battlefields, while others progressed no further than the drawing board. Many projects resulted in magnificent machines of war, but many others turned out to be complete failures.
The idea of building the largest tank in the history of warfare belonged to this batch of Hitler’s wonder weapons. Hitler’s army mainly fought on land, and they wanted a tank that would make these land battles easier to win. The main feature of this new tank was its enormous size, surpassing everything made up to that point. Even the heaviest of tanks would have seemed like toys in comparison. Like all dictators of his time, Adolf Hitler was enamored with weapons that could showcase his military strength. When Hitler was at the peak of his power in 1942, he was presented with an idea to build the largest tank ever devised, designed by Edward Grata, a director of the famous Krupp company. Hitler was thrilled; he saw the tank’s imposing appearance as a perfect match for the image of the German army he wanted to build.
At that time, Porsche had started constructing a heavy tank called the “Maus,” which was supposed to be the mighty bellwether of the German Panzer. However, the Maus was nothing compared to its larger cousin, named the “Ratte.” The Ratte was part of a land battleship concept that had been in research since the 1930s. The pioneering nation in this research was the Soviet Union, with a project known as the TG-5. Their idea was to build a multi-engine driven tank weighing 1,000 metric tons and armed with a 107-millimeter main gun and four sub-turrets. One of the engineers working on the project was Edward. Upon his return to Germany, Grata brought his own ideas for building a giant tank. He started working as a director of the Krupp company, and in June 1942, he had the opportunity to present his ideas to Hitler himself. The Führer showed great enthusiasm for the project and ordered further design studies.
Grata responded with a series of drawings as a base for the future project designated the Land Cruiser P1000 Ratte. Grata outlined the weight of the Ratte tank to be a staggering 1,000 metric tons, an enormous weight compared to any other tank at that time. The latest German tank coming out of the factories, the Tiger I, was only 54 tons. The Ratte’s armament set alone weighed 300 tons, with the armor and frame weighing 200 tons, and its track and propulsion engines 100 tons. The thickness of the armor varied from 5.9 to 14.2 inches (150 to 360 millimeters). The mammoth weight of the tank was accompanied by its huge dimensions: the Ratte was projected to be 115 feet (35 meters) long and 46 feet (14 meters) wide, with its gun facing forward, extending its length to 128 feet (39 meters). The height of the tank was 36 feet (11 meters), proportionate to a three-story building. The Ratte was so large that it even had its own lavatory system and a vehicle bay to hold two BMW R12 motorcycles. While it was projected to have a crew of 41 men, the dimensions and weight of the tank necessitated very wide tracks to provide proper pressure distribution on the ground.
The Ratte was designed to have six tracks, each 3.9 feet (1.2 meters) wide, three on each side of the chassis. Setting a 1,000-ton monster into motion would have been a challenging task, requiring about 12,000 kilowatts (16,000 horsepower) to move the tank. The first choice of propulsion was two MAN V12 Z3244 24-cylinder diesel engines of 6,300 kilowatts (8,400 horsepower), similar to those already in use by German U-boats. The alternative was to use eight Daimler-Benz MB 50120-cylinder diesel engines of 1,500 kilowatts (2,000 horsepower), which were used on German E-boats. Both solutions were projected to provide a top speed of 25 miles per hour (40 kilometers per hour). However, it would have been unlikely for the tank to achieve that speed due to potential suspension and transmission problems.
The intended armament of the tank was equally impressive. The Ratte was equipped with several types of guns, two of which were the main 28-centimeter SKC 34 naval guns, developed in the 1930s for use on Scharnhorst-class battleships. These guns were extremely powerful, capable of penetrating armor up to 17.7 inches thick at a distance of three miles, with a maximum range of 25.6 miles. As an additional armament, the Ratte was also armed with a KWK-44 L/55 anti-tank gun. There are no records indicating whether this gun was planned to be positioned at the front with the main guns or on a separate turret on the opposite side of the tank. Other armaments included an unknown number of 20-millimeter anti-aircraft guns and 15-millimeter autocannons typically used on German aircraft.
The frightening size of the Ratte was the feature on which the entire project was based, but paradoxically, this was also the project’s main drawback. First, there was no tank factory in Germany large enough to assemble such a huge vehicle armed with naval guns. For that reason, a shipbuilding yard would have been required. Just building a prototype tank would have taken several months, using much of the yard’s resources and space—a luxury the Germans could not afford at the time. Even if the tank was built, putting it into action would have been a logistical nightmare. Due to its massive weight of 1,000 tons, the Ratte could not have been transported to battlefields by railway. Using its own propulsion at a speed lower than 25 miles per hour, the Ratte would have taken an eternity to arrive at the front. If it broke down along the way, it would have been impossible to tow, as it would have required another tank of the same size to accomplish the task. Additionally, because of its weight, the Ratte could not have used roads or bridges without destroying them. The only favorable characteristic was the tank’s high ground clearance of six feet, which would have allowed it to cross through a river.
In the end, while the Ratte might have been considered a mighty tank, it would have also been a remarkably easy target. The Ratte’s thick armor might have posed a challenge for Allied tanks, but not for Allied bombers. Despite its heavy armor, it could not have withstood aerial bombardments. Being a gigantic and slow vehicle would have made it a perfect target for air attacks. The Ratte was a huge, powerful, but ultimately impractical weapon. The idea of building the tank emerged in 1942, but the German industry was already overexerted by the war effort. Spending valuable time and resources on building the largest tank in the world would have impeded that same effort for no significant result. That’s why the Minister of Armaments, Albert Speer, canceled the project in early 1943 before it even entered the production phase. The Ratte remained just another of Hitler’s grand fantasies, as German General Heinz Guderian wrote in his autobiography, “Hitler’s fantasy led him into the realm of the gigantic.”
