Austria-Hungary (1911)
Tank Design – Concept Only

“The claim that the Kampfwagen is an English invention – the term ‘tank’ should be avoided, being a foreign word and technically incorrect, – appears in the various newspapers and journals. This claim is completely wrong. The Kampfwagen, which is no more than an armored and equipped tracked vehicle is as less an invention as the armored car. This judgment was made by the authority in this area, the Patent Office, when I, in 1911, applied for a patent for the Kampfwagen -Back then I called it Motorgeschütz-. I had to revise my patent and could only patent the obstacle crossing device.”

This piece, part of a larger column, was written by Austrian officer Günther Burstyn in 1924, in which he opposed the conception that the tank was an English invention, and explains why he is not the inventor either, although he specifically notes that his idea was at least earlier than the English ideas he knew of.

Günther Burstyn

Günther Adolf Burstyn was born on July 6, 1879, in Bad Aussee, a town in the geographical center of Austria. He went to gymnasium in Vienna, after which he joined the Pionierkadettenschule (Engineer cadet school) located in Hainburg an der Donau, a town to the west of Bratislava. In 1899, Burstyn joined the Eisenbahn- und Telegraphenregiment (Railway- and Telegraph regiment) of the Austro-Hungarian Army. From 1902 until 1904, he served in the military harbor of Pola as commander of the local Fortress Telegraph Squadron. After this position, he followed a ‘higher engineering course’, which he completed in November 1906 and was promoted to Oberleutnant. He then was attached to the Engineer Staff of the Engineers Directorate in the city of Trient (Trento, Italy).

The Emergence of the Motorgeschütz

During his service in the harbor of Pola, on March 15, 1903, Burstyn was invited by his cousin, who was a Marine officer, to join him on a torpedo boat trip. During this trip, impressed by the ship’s speed, power, and protection, the idea arose in Burstyn’s mind for a ‘land torpedo boat’ and he wrote: “Like this, we have to approach the enemy on land as well.” Burstyn realized that such a vehicle should be armored, capable of off-road maneuvers, as well as being able to cross trenches. He thought about the gasoline engine as the propulsion of the vehicle.

In March 1906, he was confronted with his idea again. While following the higher engineering course, he visited the 6th National Automotive Exhibition in Vienna. There, he saw the Austro-Daimler Panzerautomobil, development of which was initiated in 1904 and had been completed in 1905, being one of the very first armored cars in history. He immediately realized the potential of this four-wheel driven vehicle, which in some way matched his idea, although he saw the four small wheels as a huge limitation, as it did not allow the use on rough and muddy terrain, due to the high ground pressure, and it could not cross trenches and ditches either. As such, he sought a way to overcome these limitations in off-road mobility.

After he completed his course and was promoted, he moved to Trento where he was stationed from November 1906 until 1908. There, he saw how the wheels of heavy guns were equipped with ‘plate chains’ to reduce ground pressure. That made him think about how to apply this kind of chain around several wheels, creating a ‘band chain’. He called this chain of metal plates ‘Gleitbänder’. Unaware of the tracked tractor built by the firm Holt in the USA, designed by the English company Hornsby, and patented in Austria in 1911, he finalized his own design, resolved issues, and in October 1911, he sent his design to the Austro-Hungarian War Ministry hoping that they would have interest in such a vehicle.

He called his vehicle ‘Motorgeschütz’, meaning motorized gun. This term had already been occasionally used before 1911 to describe an armored vehicle in the Austro-Hungarian Empire. For example, an edition of the Allgemeine Sport Zeitung (General Sports Magazine) from 1906 refers to the French CGV armored car as ‘gepanzerte Motorgeschütze’.

Design

It is impossible to describe the design of the Motorgeschütz in much detail because the details do not exist. As Burstyn was not allowed to patent the complete design, nor the suspension, he only patented the arms, which meant that he had to leave out many of the design details, resulting in a brief patent. So, apart from the arms, the design of the vehicle is relatively obscure with many important details missing.

The Motorgeschütz featured a box-like armored structure. The lower glacis was placed vertically while the upper glacis was heavily sloped, behind which the curved base for the round turret was located. The turret could not rotate 360 degrees, as it was blocked by the compartment behind the turret, and had a maximum rotation of approximately 300 degrees. The main armament, a quick-firing gun, was located in this turret. Although the gun has often been interpreted to be a 37 mm gun, it remains unclear which caliber gun Burstyn envisioned to use. Inside the turret, two crewmembers were located whose seats were located on the left and right of the main gun. Secondary armament is said to have consisted of two machine guns, which probably were meant to be fired through the several vision ports.

The third crew member sat in a compartment behind the turret with three vision ports facing to both sides and the back. The question how the crew was arranged (commander, driver, gunner) inside the turret has been speculated on, with the driver in the back, and commander and gunner in the turret, however, the final layout is unknown, especially since the patents provide no definitive answer either. Give the amount of available space, the engine was most likely to be mounted in the back of the vehicle, it is assumed that this would be an already existing regular truck engine, which at the time, produced on average 60 hp. The vehicle, without arms, had a length of 3.5 m and width and height were both 1.9 m. The turret had a diameter of 1.3 m.

Comparison between the design of 1911 and 1912. The main differences are the differently positioned road wheels and the addition of two wheels, one on each end, to which the arms are attached.

The Arms

The most distinctive features of the Motorgeschütz were the four movable arms, two on the front and two on the rear. The arms were to assist the vehicle in overcoming obstacles. They featured a small wheel on the end so the arms would not suddenly get stuck in the ground. The arms pivoted on the very front and rear wheels. They were vertically adjustable by moving a beam that was mounted on the arm on one side and attached to a crosshead with a spindle, which could slide back and forth in a special casing. The spindle did not rotate but was moved back and forth by a bevel gear which in turn was powered by the engine. How the engine was to power the bevel gear is not specified. The patent drawings also seem to include a hand crank device with which the bevel gear could be operated manually, but if this would have worked is doubtful.

The arms could not be operated from one central position. The rear arms were operated by the crewmember in the rear compartment, while the front arms were operated by the crew in the turret. If the turret was turned to a side, the operating handle of either one of the front beams would become very hard to reach, if not unreachable. Setting the problems concerning power and handling aside, the question remains whether the arms would actually help to cross obstacles. Lifting of the vehicle would mean that the ground pressure was to be greatly increased as all the weight had to be transferred through the small wheel on the beam and a small part of the tracks. The tracks would also lose most of their traction which would increase the chance of the vehicle getting stuck in muddy terrain.

Rejection of the Motorgeschütz

After Burstyn submitted his design and scale model in October 1911, three months later, in January 1912, the War Ministry sent a response: “The project at hand has to be assessed primarily from the automotive point of view, because it introduces a new kind of motor vehicle construction intended for driving in the terrain. It does not matter at first whether the wagon is being used to transport a gun or for any other purpose.” Due to this opinion, Burstyn’s submission was sent to the head of the Automotive Sector of the Army. Who reacted: “Based on this opinion, the project in question is not suitable to form the subject of a trial at the expense of the Army Administration. It is therefore requested to inform the proponent that the realization of his project cannot be done at the expense of the army administration.”

In other words: the Ministry did not want to fund the new project as it did not have enough faith in the new design to invest in it. If Burstyn wanted the vehicle to be built, he had to use private funds, which he did not have. This was a major setback for Burstyn who had expected better from his nation. Interestingly, the head of the automotive sector, who had the final say in accepting or discarding the vehicle, was Lieutenant Colonel Robert Wolf. However, it was Wolf who can be credited most for the design of the Austro-Daimler Panzerautomobil from 1905 which was a significant design in armored vehicle history. Wolf, familiar with armored vehicle design, looked at the Motorgeschütz as nothing more than another armored car and probably influenced by his own experience, the Austro-Daimler had been rejected as well, decided that there was no future for the Motorgeschütz.

Burstyn did not give up his design directly. He filed another patent in the German Empire and approached the German War Ministry, but they turned down the design as well. Burstyn did not offer his design to other countries but instead went to the press. He wrote an article for the second Streffleurs Militärische Zeitung (Military Magazine of Streffleur) of 1912 and furthermore his design was described and positively evaluated by German Major Blümer in the ninth Kriegstechnischen Zeitschrift (Military Technical Magazine) of 1912. But his idea was not picked up, there came no support.

The conservatism of the German and Austro-Hungarian war ministries is often blamed for not accepting the Motorgeschütz but, although this is true, the other major issue was the vagueness of Burstyn’s design. Not only the descriptions from the patents are very brief, but the model did not have much detail and many details were not specified, like the type of engine, type of gun, and sturdiness of suspension.

Coincidently, by the time Burstyn submitted his design, the first Holt caterpillar tractors arrived in the Austro-Hungarian Empire and its design had been patented in Austria-Hungary in 1911. It is important to stress that the Motorgeschütz was not based upon the Holt tractor design. When Dr. Leo Steiner from Budapest first gained interest in the vehicle he ordered it to be tested in Austria-Hungary. Tests were conducted since January 1912 in Felixdorf, a town north to Wiener Neustadt. These tests were successful and sixteen were ordered. They formed the Automobilabteilung 24 Spezialautolenker (Car Unit 24 Special car drivers) of the engineering troops. In case of need, it was envisioned to use the tractors to tow 30.5 cm mortars if used in rougher terrain.

The Holt tractor was to become the inspiration for several tracked armored vehicles during the First World War, and the chassis served as the base for the first operational French tanks. At the same time, however, the British rejected the Holt chassis as useless for an armored vehicle.

Legacy

In 1914, the Austro-Hungarian Army went to war without a single armored vehicle. Burstyn would have liked to bring his invention under the attention of the War Ministry once again, but the thought that his idea would once more be rejected withheld him from doing so. Apart from a few armored vehicles, the Austro-Hungarian army never fielded any tanks.

After the Austro-Hungarian Empire was dissolved at the end of WWI in 1918, Burstyn continued his military career in the Austrian Army. He retired in 1934 and became general baurat. He kept his interest in tanks and anti-tank defenses. In September 1935, he filed a patent for a tank trap. After Germany annexed Austria in 1938, he offered his service to the German War Office and he made several designs, including an armored raft for amphibious operations. For this effort, he was awarded the War Merit Cross 1st and 2nd class in November 1941, which he received from General Alfred Streccius. In April 1945, Burstyn took his own life, in fear of being taken prisoner by the Soviet Army.

Scale Models and a Full-Size Replica

Two scale models of the Motorgeschütz were constructed, of which at least one was made by Burstyn, and were exhibited in museums, one in the Pionier Museum in Klosterneuburg and another in the Technischen Museum in Vienna. In 2011, the Heeresgeschichtliches Museum (HGM) hosted a temporary exhibition of military inventions made in Austria over 500 years. As part of this, a full-size replica of the Motorgeschütz was created and placed in front of the museum. After the exhibition was over, the vehicle was moved inside and is currently on view in the Panzer gallery.

Conclusion

Although this statement is sometimes made too easily, the Motorgeschütz was, even with its shortcomings, truly ahead of its time. However, this was only the indirect reason why it never came further than the drawing board. The main reasons were the lack of support from both the Prussian and Austro-Hungarian ministries and Burstyn having no contacts in the right places who would argue for his case.

Its combination of off-road mobility, armor, and weaponry meant it was the very first example of an armored vehicle that matched the general characteristics of tanks that were to come later. One can only speculate what would have happened if the Motorgeschütz was actually built. There is no doubt it would have brought the Austro-Hungarian forces an advantage during the early days of the war, but if it would have changed the outcome of the war is a question impossible to answer and there is no need for an answer either because the Motorgeschütz never became reality. The tank was destined to be a child of war, not a child of peace.
