This bizarre armored tractor was jointly designed by Alkett, Krupp and Mercedes-Benz with a silhouette truly worthy of a machine of science fiction.

 

The hull of the vehicle was covered in variable shielding between 10-40 mm, with a floor shielding of 40 mm designed to resist the explosion of  multiple mines. The floor itself was reinforced by an additional shielding of 20 mm inside the machine for added protection.

 

The first prototype VsKfz was completed in 1942. The presence of manufacturing plates in the vehicle makes it possible to establish the following conclusions: The manufacturer was Alkett of Berlin and on a plate Nmr VsKfz 617 and Nmr 9537 is engraved. VsKfz 617 refers to a Pzkfw 1 tank and 9537 is the chassis number. That would imply that the turret is of an Ausf. A type but this one has the specific characteristics of an Ausf. B; in particular, the hooks of turret (Traghaken) are located on the top and not the side walls of an Ausf. A. The superstructure possesses a turret of the Pz.Kpfw I tank which is equipped with two 7.92mm MG-34 machine guns ensuring the close defense of the machine.

 

During these ground displacements, the changes of direction were accomplished by orientation of an aft wheel controlled by a system of chains actuated by a wheel. The mobility of the machine was ensured by two enormous discs on which heavy mobile shoes were fixed which were theoretically resistant to the explosions of all mines. These shoes have a form resembling those which equipped the wheels of heavy pieces of German PAK artillery. The principal role of the vehicle was the detonation of mines to obtain a cleared access path for German infantry and AFVs. This was to be achieved by the exercise of a very strong ground pressure using the nine shoes with permanent ground contact.

 

During the trial tests, it proved that this vehicle was unsuited to the operations of modern mechanized warfare. Its ponderous weight, slow speed, and its awkward size made the Minenräumer (minesweeper) a large target for opposing artillery and the project was thus abandoned.

 

In April 1945, during their advance, Soviet troops captured this vehicle in the center of the testing grounds of Kummersdorf. Stored a few times in Dresden, it was then dispatched to the USSR. In 1947, it underwent several evaluation tests. Unfortunately, the bad conditions of storage and the carriage had caused irrevocable damage with the mine clearance system so the tests were limited to a short evaluation of movements instead.

 

The Alkett VsKfz now resides in the Kubinka Museum outside Moscow.

Alkett-Räumgerät

 

This strange AFV was found by the Soviet troops at Kummersdorf proving grounds in 1945 and was then stored at the Soviet military base in Dresden. In 1947, it was delivered to Kubinka proving grounds for tests together with other German AFVs. The tests could not be completed because the minesweeping mechanisms of the mineroller were badly damaged during the transportation and only movement and tactical tests were made. The design was the joint project by Alkett, Krupp and Mercedes-Benz and construction was finished in early 1942.

 

The appearance of this AFV was very strange and unusual. The vehicle's body was mounted on the heavy gun frame with the cabin containing the fighting compartment, engine and the turret from PzKpfw I armed by the two MG-34 machine guns for close defense. The body armor was 20 to 40mm thick. The bottom had to withstand the explosive power of mines and was 80mm thick. There were inside armor plates in this AFV. Turning the mineroller was done by the small steering wheel placed in the rear part of the body.


Driving was done by turning of the steering wheel and via the gear selector The wheels were mounted with 75mm wide brake shoes that were controlled directly from the fighting compartment. The moving parts of this mineroller were caterpillar trucks with shoe pads fixed onto the driving wheels. They were similar to those used on wheels of the German heavy field guns in the WWI. The explosives theoretically could not damage those pads. The tests showed that the weight of this AFV, its low speed and height made an easy target for enemy artillery. This AFV was constructed under the influence of high Panzer losses on the Soviet minefields. It was to go before the tanks in the offensive operations. It appears that the designers understood that this AFV was useless in comparison with the ordinary tanks mounted with mineplows and was abandoned at the proving grounds.

Today Alkett-Räumgerät can be seen in the Museum of Armored Forces in Kubinka in Russia.


Minenräumpanzer III / Minenräumgerät mit PzKpfw Antrieb

 

One of the most interesting prototypes based Panzer III's chassis was Minenräumpanzer III - mine clearing/mine destroyer tank. This was another extremely weird vehicle developed by Krupp. The idea was simply to run all over the mines with a reinforced kit of tracks, the high clearance of the hull minimizing the blast to the crew compartment.

 

It proved to be unsuccessful and never entered production.








 
 





         






Minenräumer III
Model by Valentin Bueno

 



One of the strangest German vehicles discovered after the war was a huge four wheeled device built by Krupp. This vehicle was the Krupp Räumer S.

This vehicle was built in 1944. It weighed in at 130 tons and was support by 2.7 meter diameter steel wheels. The huge vehicle pivoted in the middle to keep the vehicles turning circle a reasonable distance. Each half of the Räumer S was powered by a 12-cylinder Maybach HL90 engine.

There is still discussion about this vehicles purpose, but it is widely believed that due to the vehicle’s high ground clearance and well protected cabin it was used to clear mine fields. The front and rear wheels were at different spacing in order to create a bigger sweep area. It had a cab at either end which allowed it to reverse back through mine fields (assuming that was its purpose) without having to turn around. There seems to be a flaw with the mine sweeping role, that is the connection in the middle seems quite exposed and would seemingly be prone to damage from exploding mines.

The only finished Krupp Räumer-S minesweeper was captured in Hillersleben in 1945 by the Americans

Leichter Ladungsträger Goliath Sd.Kfz.302

Specific Features: Measuring about five feet in length, the Goliath was a tracked demolition vehicle powered by two electric motors. With a screaming top-speed of six miles per hour the Goliath wasn't going to be winning many races against tanks, but it wasn't intended to. The purpose of the Goliath was to carry a 60kg demolition charge into place and detonate it immediately. Unlike the Japanese the Germans had almost no vehicles that actively encouraged the pilot to commit suicide. Even their plane designed to ram into bombers featured the slim safety measure of a detachable cockpit. To this end the Goliath was essentially a remote controlled bomb on treads

 

As the Goliath advanced it would spool out a control wire onto the ground, allowing an operator to guide the vehicle from the safety of a trench or bunker. Later versions of the Goliath utilized a motorcycle engine in place of the electric motors, could carry a heavier demolition charge, and were slightly faster. The early 1942 versions of the Goliath were prone to small-arms fire, so in the 1943 version the armor was upgraded along with the engine. While anything bigger than a rifle would make short work of the Goliath it was never intended for use in a running battle. It was designed with one purpose: to explode!

 

History: Development of the Goliath began in 1940 after the Germans utilized the much larger, slower, and more cumbersome "Borgward" for minefield clearance. By reducing the size of the vehicle from 1.5 tons to a little over 700lbs the Germans created a remote-controlled demolition vehicle that could be towed into position and then manhandled without much difficulty by a crew of four or five men.  The unit had a range of only 650 meters and was used almost exclusively for blowing holes in minefields. By the end of the war over 7,000 Goliaths had been produced and certainly a number of them were used offensively, but this was not their intended purpose.  The Goliaths served most notably in the Kursk Bulge to clear a way for advancing German armor through the deadly minefields.

 

Some attempts were made at using a TV camera mounted on the Goliath but these proved largely ineffective and the concept was abandoned.
