Unusual Roscii tanks and the Soviet Union. BT-IP 1936

BT series tanks, which were built in series in the 30s of the last century, as we know, have been designed on the basis of machine «Christie 1930" South American engineer Walter Christie, received the USSR, because the creation of their own tanks in our country over the years has been on quite a low level of in comparison with global manufacturers such as Britain, France and the United States of America. With the highest speed properties, this tank successfully fit into the military doctrine of profound breakthrough was common at the time in the top military leadership of the country.

As sung one of the songs so far:
"And on the enemy's land we defeat the enemy
A little blood, a mighty blow … "

Should have to pay tribute to the engineer Walter Christie, his tank came out really greyhound, but the highest speed he could develop only on roads and hard ground, but military actions usually are not conducted on the roads. A break enemy defense in depth, with a strong and well-entrenched enemy before attacking the main parts usually conducted preliminary bombardment, which turns the area into a kind of "lunar surface", and this "landscaping" armored units, supported by infantry had to go to break. This is where the advantage of BT tanks, which would seem to give them the highest speed and maneuverability, reduced to a minimum. As light infantry support tank, he could not do such tasks. It did not suit many military engineers and designers. It was necessary to create and make not only high-speed and maneuverability tank, and the wielding of the highest cross. One of these tanks on a plan of professional self-taught engineer, military technician rank 2 NF Tsiganova had to be a tank BT-IP (IP-Joseph Stalin).

Work on the creation of the tank began in late 1935, a group of engineers under the control of NF Tsiganova, on behalf of the commander of the SVR IE Yakir. As a result of careful and hard work in April 1935, the latest figures have been designed machine, BT-2 IP as its model in 1:5 scale. According to the calculations, NF Tsiganova tank had to reach speeds of over 100 km / h, it was indescribable to long to have a small (less than 6 m) turning radius and smooth running. Major changes have touched the chassis and car reservations body, arms planned to throw the same. The main feature of the car was equipped with 3 pairs of top rollers, new wheel drive track mover and completely changed the suspension elements. Also worth mentioning is the installation on tank additional fuel tanks, which greatly increased the speed in store. In the summer of 1936 began testing the newest machine, where it has shown good results and overshadowed by cross-serial standards in five (!) Times. The People's Commissar of Defense Kliment Voroshilov gave the order to continue work on the project BT-2 IP. But managing the Kharkov Locomotive Works, which was carried out project, to sabotage his progress, and soon all the work on it was stopped.

But soon NF Ciganov returned to the idea of growing cross-BT series tanks, and the first of 1936, work began on a new project BT-5 IP. The project was planned to change the chassis go into service of the new tank BT-5, as BT-2 and IP-3-equip it with two pairs of drive wheels to increase the patency stroke increment in store by installing auxiliary fuel tank in the rear part of the machine body and increment reservation. Which was produced by the 1936 illumine all on the same KhPZ. On tests machine developed a speed of 80 km per hour on the wheels on the hard ground, easily overcame the rise of more than 23 °, the calculated stroke in store, with additional tanks larger than 600 liters. amounted to 260 and 450 km for tracked and wheeled traffic, respectively.

The scheme of the box BT-5 IC

But again, the internal intrigues and unwillingness to engage in improving the management KhPZ series of tanks led to the fact that the future development project BT-5 EC has not received. NF Tsyganov had written a letter in which he described the situation surrounding his project, here are a few lines from it: "Pest Firsov, the former head of KB KhPZ the factory, where it was transferred to pest Neumann, former chief Spetsmashtresta, the plant number 48 (Kharkiv ), where those. director was the wrecker-fascist Simsk who dragged the factory number 48 Gakkel fascist and put him in charge of the production of the BT-IP. Farmanyants … — Deputy Chief of the 8th Ch. Mgmt. ICPC tried to disrupt production of the BT-IP. " After that, the letters of the project were continued, and by the end of 1936 was 10 cars BT-IP-based light tank BT. In March 1937 the car took to the troop tests, during which it was completed more than 1,500 km, and then tank BT-5 IC has shown good results. Machine retain mobility even when damaged one of the tracks and the loss of 2-rollers.

BT-5 IC during test

According to the views of the Commission, to monitor the progress of the tests, the tank BT-5 IC has to be taken into service. GG Bokisom while ABTU chief of the Red Army, it was ordered, "… command, the Kharkov plant paravozostroitelnomu to 5 cars for 1937, to remove the identified shortcomings of the process of military trials for the upcoming ability to launch into production." Also conducted work on the installation of an improved chassis for the new tank BT-7, but first 1938 NF Ciganov was arrested, and all work on the project was abandoned.
