    8.4 km.

    year development:

    fighting machine BM-13-CH Fighting vehicle BM-13-CH was a further improvement of the launchers for firing 132-mm rockets M-13, and the new M-13-DD-1. < / p>

    Prototyping BM-13-CH was performed at the Moscow plant "Compressor" (№ 733). They have passed the polygon and sea trials, after which the installation will go into series production. In 1945, at the "Compressor" was made several divisions intended for use in the storming of Berlin, which has created a special troop part under the command of Major RB Vannikov.

    After the war ended in 1945, BM-13-CH passed military tests. Were demonstrated good results, however, in view of the forthcoming modernization rockets M-13, the installation was put into service. After a series of 1946 she was taken out of production (Order number 27 Nkomo from 24.10.1946 years). However, in 1950, were produced quick guide to the combat vehicle BM-13-CH.

    On the basis of the directive

    Deputy Commander of the Armed Forces Artillery number of 348212ss 05.04.46g. during the period from May 10 to June 10, 1946 at Sofrinsky artpoligone military tests were conducted combat vehicles BM-8-CH and repeated military tests BM-13-CH (see gallery). Tests were conducted under the chairmanship of the Chief of the 6th Faculty Artillery Academy Lieutenant General PN Kuleshov artillery to ensure military trials was isolated Division 22th Separate Guards Mortar Regiment of the Red Polotsk. Tests were subjected to four combat vehicles BM-8-CH, BM-13-CH design and construction of the plant number 733 MMiP. Tests on fire fighting vehicles and mileage carried out in parallel with the regular fighting machines BM-8-48 and BM-13.

    During the tests were carried out live firing with the following tasks:

    direct fire of a war machine (BM-8 and BM-CH-CH-13) at elevations 6 ° -7 ° and 10 ° -10 ° for the purpose opredelnie smallest angle of sight, providing security for the firing rooms and the smallest angle of sight when shooting through the cabin (4 shooting);

    shooting obnoy combat vehicle (new and standard for determining the accuracy of the fight for the maximum distance (elevation angle - 45 °) and the average distance (elevation angle of 21 ° - only for BM-13-CH) - a total of 21 shooting. < / p>

    firing battery of new combat vehicles and staff to determine the area of dispersion and density of the battery fire volley (16 firings).

    Shooting from BM-13-CH shells were made M-13, M-13-CC (improved accuracy), M-20 (explosive) and M-13-DD (long-range), and the staff of the BM-13, only M CC-13 and M-20.

    military trials results:

    When direct fire from the BM-13-CH lowest elevation angle, ensuring the safety of firing from the front to undermine progress machine was the angle of 6 °, where the breaks went no closer than 300 meters from the firing position.

    Fighting vehicle BM-13-CH has the following advantages compared with the standard BM-13:

    1. When firing BM-13-CH shell M-13 (cheaper) dissipation is reduced to practically identical with the nominal dispersion BM-13 missiles by firing M-13-CC. The average value of the effective range of the new BM-13-CH shell M-13 at 21 º elevation angles of 45 º and get more on average 600 m compared with a range of standard BM-13 missiles M-13-CC;

    2. When firing BM-13-CH-13 projectile M-CC dispersion decreased by 10% compared with a scattering of shells of M-13 is fired from the same combat vehicle;

    3. When firing BM-13-CH shells of M-20 on limiting range dissipation area decreased by 2 times by increasing the density of fire 2.5 times.

    4. For BM-13-CH shall be possible to produce firing shells of M-13-DD with a range of up to 12km limit (standard BM-13 missiles firing M-13-DD can not stand).

    were the following drawbacks BM-13-CH:

    1. Reducing the number of stems up to 10 (instead of 16 full-time) has led to a decrease in the power volley 1.6 times the density of the battery fire salvo in an average of 40% (when firing shells of M-13 and M-13-CC compared with shooting regular BM -13 shells of M-13-CC). To get from the new BM-13-CH dense fire battery volley equal density standard BM-13, it is necessary for shooting from BM-13-CH-13 projectile M-CC spend 1.5 battery volley projectile M-13 - 1.7 volley. ;

    2. The lowest elevation of the BM-13-CH with nepodkopannym forward course was 3 ° more than the standard BM-13, which increased the shortest range direct fire at about 800 meters, allowing shooting from a distance of 2700 m (at elevation tseliravnom 0 º). Native BM-13 when shooting under the same conditions has an advantage because it allows shooting at an elevation angle equal to 7 º with shooting range about 1900 m

    3. Inability to check reflector pan in the BM-13-CH, and the standard BM-13, which is a big disadvantage in direct fire;

    4. Weight artillery unit BM-13-CH 240 kg more weight standard BM-13;

    5. Height BM-13-CH 250 mm longer than the height standard BM-13;

    6. Low speed vertical lay;

    7. The inconvenience of cleaning and lubricating the screw guide situated in the center of the stack;

    8. Stopper hold enough shells on the trek - shifted 6 rounds in one BM;

    9. Replacing the damaged trunk in the cassette tape requires replacement entirely in the studio part.

    Shells M-13-DD passed military tests in the 1944 shooting of regular combat vehicles BM-13. The report on these tests, it was concluded that inability to use the shells of M-13-DD of the BM-13 without hardening the machine. During trials BM-13-CH shells of M-13-DD tight included in the guide (trunks) because axial curvature shells.

    In addition, fees deputy commanders districts GMCH in June 1946 was produced from BM-13 CH-79 shot shells of M-13-DD, of which 3 were undershooting (breaks at a distance of 5 km) and 30 detached wings stabilizer trajectory.

    When shooting at Sofrinsky range between 25/06/46 to 12.07.46g. in the amount of 360 rounds of BM-13-CH about 8% of the issued shells of M-13-DD had takeoff stabilizer wings.

    In combat vehicle BM-13-CH, as having some significant drawbacks to eliminate technical and basic operational deficiencies noted in the report of the commission to order a series of these machines in the amount of 12 pieces and put them wider testing in the army.

    Shells M-13-DD, it was decided to finalize and submit to military tests for firing of combat vehicles BM-13-CH.


    BM-13-CH applied for:

    destruction of enemy personnel located for easy open and field shelters;

    suppressing and destroying fire weapons;

    destroy tanks and other mechanized weapons of the enemy in the field of their concentration.

    Archery combat vehicles BM-13-CH was carried out only on the objectives, occupying a large area, the number of military vehicles, both of which are conducted shooting, determined depending on the task.

    Fighting vehicle BM-13-CH have sufficient maneuverability that allows a short time to focus on the important area of a large number of military vehicles and suddenly open fire. Due to the suddenness and massaging fire fighting vehicles BM-13-CH inflict a serious defeat and provided him a strong moral influence.

    BM-13-CH was a self-propelled artillery, consisting of the following main parts: the package, farm, swing frame, the base, the lifting mechanism, rotating mechanism, special equipment chassis electrical system to ignite the charge, sighting devices and vehicle chassis .

    BM-13-CH-house intended for firing rockets M-13 and M-13 missiles-DD, M-20 and M-13-CC.

    fighting vehicle was set spiral guide mounted on the basis of standard BM-13 (normalized) with a farm of BM-31-12. Each spiral guide consisted of 3 tubes, bent on the helix, and a leading guide, is a square steel rod with selected from two opposite sides bent grooves and also along the helix. One of the slots is a work in which the front pin projectile informing it a spin when fired.

    Three pipes leading guide attached to the strips using a housing shaped trunk, which moved inside the shell. Barrels fastened by welding four cassettes. Two upper cassette had two barrel bottom two - three, thus consisted of a set of guide shafts 10.

    fighting machine BM-13-CH Each trunk was in the breech lock, holding the shell from falling back and on the progress in the campaign ahead. Stop function automatically. To unload the projectile stopper equipped with a pen, with which he opened.

    On the sides

    leading guide to the location of the stop were reinforced two electric contact, one on the side by which sources current from the battery to pirosvecham projectile. Electrocontacts stopper and protected housing.

    In each barrel muzzle slants were at the leading guide and one of the adjacent tubes to avoid grazing the rear (not working) pin of the projectile during its departure from the trunk. Cassettes were removable and strengthened on the farm by bolting.

    Package 1 consisted of ten cells of the spiral guide, intended for manufacture of shells. Slides were mounted in a cell of four cassettes, which are mounted on a farm in two rows.

    Farm 2 consists of grid platform, welded from angles. Farm along with a package of guide cells could be rotated in a vertical plane about an axis bushings brackets swing frame.

    Swing frame consisted of a frame of welded channels, and two brackets. Together with the farm and the packet is routed cells she turned in a horizontal plane about an axis fixed on the basis of.

    base is a rectangular frame, welded from sills and was still fixed on the chassis side members of the vehicle. Were fixed on the basis of all the major components of the artillery.


    3 and turning 4 screw type mechanisms. From hoist package guides cells could be given elevation angles from +10 ° to +45 °. Using the rotary mechanism changed traverse package guides within 10 ° (left and right) from the central position.

    Special equipment consisted of a chassis cab protection and fuel tank, jacks, box for spare parts and battery box. Privacy protected the cockpit and the cabin is in her calculation of the gas jet impact projectile when fired.

    From jacks 7 -axis leveling ensured farm installation combat vehicle on uneven terrain. In addition, reduced vibrations jacks combat vehicle when firing.


    battery box 5 placed two alkaline batteries 5-ICH-45, which served as a source of current electrical system to ignite the charge. This system consisted of two alkaline batteries 5-ICH-45, switch, circuit breaker, junction box and wiring system. When the switch current through the switch, junction box and wiring system was brought to the contacts guides cells and provides ignition squib shells.

    Sights include: the sight of a 76-mm gun mod. 1942 panorama and group transition details.

    package, farm, swing frame, base, mechanisms aiming, sighting devices and electrical system for ignition charge artillery unit were fighting machine. Artillery unit mounted on the chassis of the car and for protection from dust, dirt and atmospheric precipitation in the stowed position covered with a canvas cover (see diagram).
