Tanks overseas


And they were there in the 20s of the twentieth century? Quite a reasonable question, because of those who are interested history armored vehicles, you probably read that the Americans before the Second World War had neither tanks, nor ... experience in their design. They remember the W. Christie's tank (how could it be without it ?!), and so - well, just very backward was there, overseas, tank design. However, was it really so? At one time I was very lucky: my friend, the artist I. Zeynalov, gave me two volumes of battered Heigl reference books from the 30s at once. And while reading them, I was surprised to find that it was in the United States at this time that numerous models of a wide variety of light and medium tanks were created, although they were not accepted into service. That is, American engineers began working on them literally a few years after the end of the First World War.


The Heigl handbook is the most informative handbook of the 30s, dedicated to armored vehicles ...

The private firm "James Cunningham, Son and Company" was also engaged in the development of new promising models of tanks. The founder of the company, an immigrant from Ireland, found himself in America and chose the career of a production worker. In 1834 he organized an office for the production of horse-drawn carriages. Moreover, there are crews for every taste: from mail carriages to hearses, inclusive. In 1908, the company even began to produce cars, although it made them mainly for its regular customers, assembled from ready-made parts taken from different companies.


And here he is just writing about the experienced American T1 tanks

Meanwhile, already in 1922, the American military prepared a technical assignment for a new light tank and announced a competition for its promising model, in which any company could take part. The tank was supposed to be armed with a 37-mm cannon and a 7,62-mm machine gun, have bulletproof armor, a speed of about 20 km / h and a crew of two. And it was the Cunningham company that won this competition and on March 15, 1927 received an order for an experimental T1 tank (that is, "Test" - experienced). The engine was installed on the front of the tank, and the fighting compartment was installed in the back. The chassis was taken from a tractor, so it had a large number of small-diameter road wheels (8 per side) with almost no suspension. The tank driver sat on the axis of the hull, and the gunner commander was in the turret. There were two hatches: one on the tower above, and the other in the rear armor plate of the hull in the form of a double door. So it was very easy to leave the tank if something happened. The idea was interesting and promising: to create a cheap tank that can be produced by ordinary tractor plants!


As you can see, there is a very detailed description of the car on the left. More details simply do not exist!

On September 1, the tank was ready, although instead of a turret, it had a wooden model on it. The sea trials were not very successful, but on the whole the tank showed itself better than the Renault. Perhaps the reason was the good 8 hp V-110 engine. from. and a well-developed and reliable transmission. True, the armor was only 10 mm thick and, moreover, it stood upright. The hull was partly welded, partly riveted.


Most of all, the T1 tank looked like ... a tractor

On the basis of this chassis, the military ordered six vehicles from the company at once: four improved T1E1 tanks and two light transporters without turrets - also T1E1. The shape of the hull was changed for the new model, and the fuel tanks were placed along the sides of the cabin on fenders. Now it had a turret with armament: a 37-mm gun and a 7,62-mm Browning machine gun. And then something happened that every arms manufacturer dreams of in the United States: on January 24, 1928, the tank was accepted into service under the designation M1 light tank ("model"). The tank's weight was 7 tons (with a power-to-weight ratio of 16 hp per ton of weight), so the maximum speed was almost 30 km / h with a power reserve of 120 km.


And the chassis of the T1E6 was very similar to the chassis of the Vickers-6 tank.

Four assembled T1E1 tanks on June 20 of the same year were sent to Fort Meade, Maryland, to the first Experimental Mechanized Brigade for testing. In 57 days, one of the tanks covered more than three thousand kilometers, and did not have any serious breakdowns, but the old Renault vehicles could cover 130 km no more from repair to repair ...

But the thickness of the armor of T1E1 (10 mm), in comparison with Renault, seemed to them insufficient. Still, that one had 15 mm. Therefore, on December 8, 1928, the company was asked to make a new tank under the designation T1E2. It was completed on June 3, 1929. The engine was boosted in it, and now it developed 132 hp. from. The thickness of the armor was increased to 16 mm at the front. The obsolete 37-mm M1916 cannon was replaced with a new, long-barreled one, with an initial velocity of an armor-piercing projectile of 600 m / s. Naturally, the tank's weight increased to 8 tons, so the suspension had to be modernized as well.

True, the cross-country ability of this tank did not improve significantly. In this regard, the chassis was significantly altered on the second T1E1 machine, spring springs and hydraulic shock absorbers were installed. The engine and cannon were taken from the new T1E2, and the voltage in the power supply system from 6 volts was changed to 12. The tank received the designation TIEZ and in April 1 it also went to the next tests. They showed that the vehicle's permeability increased, but numerous production problems prevented it from being put on stream.


Projections of the T1 tank with a simplified turret without an annular fan. Of course, the double-leaf hatch on the rear armor plate looks very comfortable.

Numerous experiments have shown that the location of the engine on the front of the tank limits the driver's visibility and increases the gas content of the fighting compartment. For these reasons, the company decided to radically alter its tank by turning the engine back.

In the United States, just at this time, a new British tank "Vickers" 6 tons was tested, the suspension of which formed the basis of the new American chassis. The engine remained the same V-8, increasing power to 140 hp. from. Armament and armor were not changed. Although the turret was installed from the T1E1 tank, and not modified from the T1E2. The new tank was designated as T1E4. The weight of the vehicle was 8,5 tons. The highest speed was 37 km / h, the armament was a 37 mm semi-automatic cannon and a 7,6 mm machine gun paired with it, the armor thickness was 7-16 mm, the crew was 4 people. All tanks were equipped with a radio station, which was a novelty in tank building. Another tank with a new transmission received the designation T1E5, although outwardly it did not differ from the previous model.


T1 tank with a long-barreled 37-mm cannon

Meanwhile, the T1E6 tank appeared on the arena. This car was equipped with a 12-cylinder engine with a capacity of 245 hp. from. Thanks to this, despite the increased weight, the maximum speed remained at 32 km / h. But ... no matter how hard the designers tried, they decided to stop working on further improving tanks of this type. The army did not really like them, although ... no one denies certain advantages for them.

However, the company immediately switched to a medium tank, based on the design of a previously created light one! The order to start work was given on March 11, 1926, after which a long research in the field of layout solutions began again. At the same time, the mass of the vehicle on the assignment could not exceed 15 tons. Only three years later, namely in 1929, the design of the tank was approved by specialists from the Rock Island Arsenal. As already noted, T1E1 from Cunningham was taken as a model. In addition, the British Vickers Medium, which had just appeared, had a certain influence on the concept of the new tank.


The T2 medium tank had a turret with side slopes and a commander's mushroom-shaped turret with ring ventilation.

By 1930, a new medium tank, indexed T2, entered state trials. The weight reached 14 tons, the Liberty's engine power had a very good figure of 338 hp. from. At the same time, the speed of the car reached 40 km / h, although it was deliberately reduced to 32 km / h in order to increase the service life of its transmission and gearbox.


The materiel of the 67th Infantry Company, equipped with experienced medium tanks, Fort Benning, 1932: two far left - T1, in the center T2, two far right - tanks of W. Christie

In the turret of the T2 tank, located in the rear of the T1 tank, following the example of the T47 tank, there were a 610-mm semi-automatic gun with an initial projectile velocity of 12,7 m / s and a Browning machine gun of 37 mm caliber. This impressive arsenal was complemented by a 1931-mm cannon in the frontal armor plate of the hull, the shooter from which sat next to the driver. Putting two cannons of different calibers on one tank is, let's say, not a very reasonable decision, but what kind of firepower this tank had! True, during tests in October 2, it was nevertheless replaced with a conventional rifle-caliber machine gun. The T22 armor thickness ranged from 6 to 1930 mm, which was pretty good for a 1932 tank. The tank, by the way, was highly appreciated by the Soviet newspaper Krasnaya Zvezda in 40, which noted that two cannons and two machine guns give this tank very powerful weapons, and the speed of XNUMX km / h was noted as high. True, there was only one such tank in the United States, so it posed no particular threat to anyone. All in all, the Cunningham company produced seven experimental tank models, but none of them went into serial production! But this does not mean that its engineers did not receive a wealth of experience during their creation, moreover, a good technological base was created at the enterprise for the production of the most modern tanks at that time.

            What nonsense? From the very moment the game World of Tanks appeared, the history of the early interwar American tanks was not written only by a very lazy one. = _ = Even I wrote - though mostly about Christie's tanks. Considering that T1 Cunningham is in the game, and not even in one modification. And before igruhi, in fact, it was written more than once - by serious historians of tank building.
            I will also add that Khalepsky once originally traveled to America to conclude a contract from Amtorg for the supply of 50 T1 Cunningham (and Hoover, the then president, even gave his approval for the sale), but he saw the Christie M. 1940 tank, and that's it. wrap up ...

    Vyacheslav Olegovich, What did you offend Christie? After all, just in those years in the United States, one might say, he created the basis of the Soviet armored forces and made prototypes the most. The site, however, has a very good article by Sergei Ovodovsky, but having such a trump card as Heigl in his hands, it was possible to supplement it.

            Mwa-ha-ha ... so bloody potatoes from the first videos claimed that simulator historicity was not about them. Playability is primary, and historicity can be sacrificed.
            Well, who will play the early T-34-76 at a speed of 12-14 km / h, which stops when shifting gears and may even stall? And for greater historicity, a weight of 32 kg is screwed to the mouse - for the electric drive of the tower did not provide accuracy of aiming, and the effort on the handwheel of the manual drive - yes, that's right, 24-32 kg. Moreover, when the tower is turned by an electric drive, the image on the monitor should turn off, because:
            Electric rotary turret mechanism.
            Access to the starting flywheel of the electric drive is hindered from below by the electric motor housing, on the left by the viewing device and the tower housing, on the right by the forehead and PT-6 device. Turning the tower in any direction is possible only if the head deviates from the forehead of the PT-6 device, i.e. the rotation of the tower is actually done blindly ...

            Oh yes, the effort to press the buttons responsible for the turn and the speed of the tank's movement should also be up to 30 kg.
            Cool gameplay, huh?

    Thank you for the article. Usually in the literature, the history of American tank building begins with the M1, a licensed 6-ton Vickers, and T2, its development. Christie is mentioned as the creator of the wheeled tracked vehicles, which have not found application in America.
    D. Cunningham later took up half-track vehicles. Having acquired a patent from Kegress, he improved its design. In 1933-34 on the GMC chassis, his company built a whole series of T1 half-track artillery tractors, which were successfully tested and used in the US Army. But he failed to develop his own production, and in 1935 Cunningham stopped developing in the military field, his company produced ambulances and ... hearses. But GMC continued to release cars with its propeller. Then, A. Herrington, an engineer and owner of a company for converting serial cars into four-wheel drive, contributed to the improvement of this propeller. It was these modified Cunningham-Herrington propellers that were used in the US WWII half-track armored personnel carriers, produced during its time among about 66000 vehicles.

      You mean this car, the M3.

        How do you like this Kegresse?
        Before the Second World War, France was still the trendsetter for half-track cars.

          actually, no way) Is this a kegress?
          I think it's just a track on the drive wheels. Like our GAZ-TK or AAAA. Kegress is harder:

          )))
          And yes, all the same, the first were the Germans - the "colonial daimler" in 1908. was the grandfather of all half-gusli in their traditional sense.

            And yet this is a late Kegress with a rubber caterpillar (exposition of the automobile museum in Verkhnyaya Pyshma). The car is not a model, but a real vehicle equipped in the 20s in France by the former head of the imperial garage Kegresse with a similar snow kit.
            The Paragraph given by you is an old example with a leather gusli. Apparently in a new one with a rubber one - the designer did not bother.

              That is, a quick-detachable overroll on driving wheels is also kegress, in your opinion?

                The paragraph, I am about the specific constructor of the propulsion device of this car, and not about the author and the design of the propulsion device.
                True to the information signs, I did not fit. I listened to the guide, but he did not seem incompetent to me. By the way, the car of the late 20s. In France, rubber tracks were in vogue. As far as I know, even Renault FT-17 was installed on them. So no wonder Kegress could keep pace with the times

        There were so many modifications and manufacturers of them! M2 and M3 were produced by White (the main manufacturer), Otokar and Diamond, on their basis a mass of ACS and SPAAG was built. International Harvester produced over 16000 M5 / M9 machines, which were different from the M2 / M3. And no small merit of Cunningham is that he had a hand in creating a workable and fairly simple mover. In the USSR, half-tracked vehicles did not go at all, designs based on Kegress's principles turned out to be unreliable. For the Germans, the design of half-tracked vehicles was perfect, up to complicated and expensive.

          "The Cunningham Propulsion" is an improved Kegress propulsion unit he bought from Citroen in 1931.

      Still, I agree with those who reckon American tank building from Ford's 3-ton M1918 tankette. 15 built pieces are, no matter how you turn, a series)) And if PMA had not ended, then Ford would have completely adjusted them ... well, let not 15 thousand, as was contracted with the minob, but a fair amount is certainly a hundred in day. Plus, from the French, he knocked out a contract for one and a half thousand of these machines. Well, what didn't become a Ford became a Carden Lloyd.

        Yes, these machines were the first. Exactly the same as the tank building of the USSR was counted from the tank "Fighter for freedom comrade Lenin". We are talking about interwar tank building, on the basis of which the production of tanks began in WWII.

          Well, that is a given. Here Patton was just right to paraphrase Comrade Stalin in the spirit, they say, the developed countries ran away from us in tank building ten years ahead, we need to catch up with them in one leap) And we did.

              yes, that's probably more correct. All the same, we must pay tribute to the Americans - back in August 1940, they were selling the Aberdeen cemetery to Canadians for $ 250 apiece "Renault" aka М1917 and even incomplete "diamonds" Мк8. And after a year and a half, the M4 went into production.

                In 1939, their medium tank was considered this miracle:

                He became the reference point for the first jump to the M3 middle.
