Paper model of the tank IS-3 BN

The paper model of the IS-3 BNtank is the Soviet IS-3-BN assault tank walker ("Joseph Stalin-3-Bronya, Legs").

Materials and tools:

  1. scissors, paper knife, drawing ruler
  2. tweezers;
  3. glue brushes and paint;
  4. watercolors (or pencils), toothpicks;
  5. clear acrylic glue ("Moment", etc.);
  6. to print the model matte photo paper with a density of 170-180 g / m2;
  7. for small parts - 70-80 g / m2.

Build Tips:

  1. Before you assemble the part, read the drawings and instructions. Determine the place of each part and imagine its assembly;
  2. Make holes in details before cutting out the part;
  3. Cut only the part (s) you need right now. Unpacked items in a box, and unused sheets in a closed folder (as an option). Throwing out trash after work, carefully inspect the scrap paper;
  4. To better fold the part, it is necessary to hold the ruler along the fold line, pressing lightly with the blunt side of the knife or a toothpick so as not to damage the paper surface. Better to do it from the wrong side of the part;
  5. Keep your fingers clean and be sure to use wipes to wipe your hands, because hands may get dirty in the process;
  6. wind up cylindrical parts before gluing onto a round object of a suitable diameter, this will give them shape;
  7. Before gluing it is necessary to paint the ends of the part. White crop lines spoil the overall look of the model. To paint the ends, use watercolors or gouache paints. After selecting the desired color, apply them in a thin layer, then allow the paint to dry. About markers better to forget;
  8. Take your time with gluing. First, cut out the part, paint it from the end, wait for the paint to dry, assemble the part. Attach it to the place where it should be to make sure everything is done correctly. And only then stick. Do not forget to let the glue dry.

A bit of history

Soviet assault tank walker IS-3-BN

Despite the fact that the tracked propulsion unit provided the first tank with high maneuverability, after the end of the First World War, the designer did not leave any attempts to improve it. One of the ways to improve maneuverability in the interwar period was tank “legs” of various designs: additional levers, articulated thrusts, “legs” for overcoming ditches and trenches.

The tank designers of the USSR, like their colleagues from abroad, experimented with various exotic designs. Shagohody were developed in Ostebbyuro ("Special technical bureau for military inventions for special purposes"), in Leningrad. In the design office of the plant number 185, on the basis of the serial tank T-26, the “jumping tank” TPP-2 (V.V. Linzer) was created, which was tested in 1937, but it was not put into service.

In April 1938 ended the civil war in Spain. General Franco’s troops captured Madrid. Shortly before this, the young Republican Alejandro Ugarte (Alejandro V í ctor Ugarte), participating in the preparation of the serial production of Soviet tanks in Spain, emigrated to the Soviet Union. The talents of the young Spaniard were useful to the Soviet Union: Alejandro was sent to the Kharkov Locomotive Works, and participated in the development of the T-34 family of tanks.

In 1943, Alejandro, still from pre-war times keen on walkers, sent a letter to Joseph Stalin. The proposal differed from most of these letters in that it contained a well-designed draft of the assault tank-walker.No one doubted the outcome of the Great Patriotic War, and it was precisely this that Alejandro focused on: in urban battles, conventional tanks and self-propelled guns had limited mobility (they could not overcome the debris), so the walker, equipped with a powerful gun, received certain advantages. The project was launched, the young designer, together with a group of like-minded people, was transferred to the Omsk Locomotive Repair Plant, from the beginning of the war it was redeployed to issuing banks.

Already in the middle of 1944, the first prototype of the walker was created, based on the units of the production T-34 and KV tanks. 6 massive armored "legs" became the mover, and the driver-mechanic could independently control 3 of 4 joints of each "leg". To ensure ease of operation, the car was equipped with a special electromechanical device-switch, thanks to which it was possible to move in a straight line and perform turns (the tanker had a usual “car” steering wheel). For the independent control of the "legs", two remote control panels on the sides of the driver's seat were intended. At the command of the remote "leg" took an arbitrary position.6 powerful electric motors located in the body of the walker were responsible for turning the legs (they were matched by the steering wheels on the console), and the articulated joints (2 for each leg) were controlled by 2-position handles resembling modern joysticks. The transmission was electro-hydraulic: in the stern of the tank, along with the usual diesel engine, there was an electric generator and a centrifugal oil pump. The prototype turned out to be quite successful, although the “switchboard” often broke down, and the management of the “legs” resembled a circus performance.

In November 1944, the State Commission, after examining the tank-walker, recommended to continue work on it, but to strengthen the reservation and armament. The prototype installed a tower of an experienced tank IS-3, the tank was finalized in accordance with the recommendations of the state commission. For military tests, another copy of the BN was built, and both walkers, which received the name of IS-3-BN shortly before, were sent to military trials in the 4th Shock Army of the 1st Baltic Front. Tank commanders and driver-mechanics became Omsk test tank testers, besides them the crew of the BN included a gunner and a loader.Tanks-walkers were attached to one of the assault groups and participated in urban battles, as a "means of strengthening." Due to its ability to move through any obstructions, as well as a specific method of conducting fire (the tank "rose" above the ruins for a shot and "hid" immediately after), the walkers received the nickname "Spiders of Baghramyan" (Ivan Khristoforovich Bagramyan - Army General, Commander 1 of the Baltic Front ).

Assault tanks-walkers "IS-3-BN" performed well in combat, supporting the fire of fighters, especially the fortified houses of Koenigsberg. April 8, 1945, one of the walkers ("No. 114"), as a result of the loss of just 2 "legs", was immobilized, and the crew had to leave the tank. It was not possible to save the test car: it remained in the territory occupied by the enemy, and German sappers blew it up. Another tank, "№113", was sent back to Omsk after the capture of Königsberg. The Second World War ended, the need for these special weapons has disappeared, and the project was canceled. Alejandro Ugarte after the war he continued to work at the Omsk plant, and in 1955 he returned to Spain. To date, not a single copy of the machines designed by Alejandro has been preserved.
