Fighting vehicle BM-8-48




    management system:





    Multiple rocket launchers




    5.515 km.

    year development:

    fighting machine BM-8-48 Fighting vehicle BM-8-48 was designed for combat use in the following main tasks:

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

    suppression and destruction of enemy firepower.


    fighting machine BM-8-48 could produce firing in groups of three projectile M-8, or one volley, releasing all 48 rounds for 8-10 seconds.

    Due to the large dispersion

    rockets shooting was to be conducted only on the objectives, occupying a large area, while several military vehicles to provide sufficient density of fire. Target shooting at the small size was ineffective.

    Fighting vehicle BM-8-48 had great maneuverability that allows a short time to focus on the important area of powerful firepower and suddenly open fire. Due to the suddenness and massaging fire fighting vehicles BM-8-48 to inflict significant damage on him and provided a strong moral influence.

    Fighting vehicle BM-8-48 was a special mobile artillery unit consisting of two main parts:

    artillery unit;

    specially equipped motor vehicle chassis on which was mounted artillery unit.

    BM-8-48 on the device is fundamentally different from the artillery. She did not have the barrel and recoil devices. The shooting was done with the guide grooves; such troughs were 48 to 48 simultaneous loading shells.

    10 - a box of spare parts;

    11 - Jacks, 12 - Fuel tank protection

    main part of the combat vehicle BM-8-48 packages were 7, top and bottom, each of which consisted of twelve guides - a total of 24 tracks. Each guide rail equipped with top and bottom guide chute in which the projectile slid his centering nubs. At the bottom of each trough had a longitudinal T-slot for the guide pins of the projectile. Guides have been combined into packages with two cross-linking - spar and installed in two rows on the farm tubular 2.

    From hoist 3 Farm with mounted packages rails can be moved in a vertical plane about an axis located in the bushes rear brackets swing frame, whereby the guide was given a desired angle of elevation from -3 ° to +45 °. In the stowed position farm was attached to the headstock, which is located on the front of the swing frame.

    To traverse the swing mechanism 4, From which swing frame 6 is rotated together with the guides around a vertical axis fixed in the center of the base. The ground was still fixed on the car chassis side members.

    used for firing unguided fragmentation shells M-8 (see diagram). Guides were charged with breech. Shells 8 M-fixed in the desired position by means of stoppers. Jet ignition charge projectiles produced piropistoletami enshrined in the breech slides, which invested squibs, flammable electric shock.

    source of electric current were two alkaline batteries type 5-ICH-45 installed in the battery box on the running chassis. For serial connection of electric squib served to switch.

    switch installed in the cab. Electrical circuit and shooting were possible only at the location of the guide across the chassis of a motor vehicle in the sector 50 ° on each side. To this end, a junction box in the middle of the swing frame, to install a contact device.

    For pickup

    fighting machine had sight mounted in the head console 5, hinged on the left flange axis farm. In the stowed position the console was attached to the farm with the help of a belt buckle or a bracket that is welded to the pipe farm, in the case of installation of the sight of the ZIS-3.


    jacks 11 provides opportunities leveling combat vehicle on uneven terrain, without undermining the wheels, reducing the time of preparation for battle. Also installed jacks when shooting reduced machine vibration.

    PetrolTank for protection from the action of the gas jet and possible mechanical damage associated with combat service machine was covered with steel plates. Spare parts, tools and accessories are stored in a drawer 10 ISP, located on the rear platform 14 .


    artillery unit combat vehicle for protection from dust, dirt and precipitation covered tarpaulin cover (see diagram).

    Except rail set with piropistoletami and farms in the prototype combat vehicle BM-8-CH nodes were fighting vehicles from BM-8-48-52 indices U-926 and U-52-927, were in service with the Guard mortar Red Army.

    During the war

    release fighting machine BM-8-48 takes a factory milling machines (Gorky), Penza engineering plant and possibly others.

    The document, dated 25.04.1946, on the study of the Main Artillery Directorate (GAU) comments on domestic armament received from troops and commanders of groups of districts and 4 Research Institute data based on the study of war experience and research on these weapons research landfills GAC the following data on the use, in particular, missile weapons Guards mortar units for the near future:

    FIRST group - weapons that should remain in the Army as a standard-issue: fighting machine BM-8-48, BM-13 and BM-31-12 all on the chassis of a motor vehicle "Studebaker".

    The second group - weapons, subject to the withdrawal of troops in reserve and storage - among others was specified fighting machine BM-8-48 on the chassis of a motor vehicle "Chevrolet".

    the third group - weapons, subject to the withdrawal of troops and implementation, as the loss of combat value: fighting machine: BM-8-48, BM-8-32, BM-8-24 chassis cars "ZIS-6" "GAZ-AA", "JEEP" and tank "T-60";

    In postwar edition as a manuscript "A Brief History of SKB GSKB Spetsmash - KBOM" edited by VP Barmina, 1 book: "Creating tactical missile 1941-1956 gg.", Moscow, 1967 . "provides the following data:" In April-June 1942, on the initiative of Chief Designer Barmina VP, development has been made fighting the BM-8-48 on chassis "Ford - Mormon" (see . Fig. ), which has been successfully tested and adopted by the Red Army. Combat BM-8-48 was the main battle to start installing missiles M-8 and was armed guards mortar units before the end of the war. Serial production installation was performed on the Penza factory number 740 Commissariat mortar weapons ".

    "At the initiative of CSC approved BS GMCH spacecraft in November 1943 was designed 48-shooter combat BM-8-48 on the chassis of the car ZIS-6 to start the rockets M-8. This setup was designed for the same purpose, and that fighting the BM-8-36 chassis car ZIS-6 and BM-8-48 chassis cars "Ford Mormon." All major components are unified structure with nodes serial combat units: package with installation guides BM-8-48, and the rotating frame, lift and swivel mechanisms guidance and junction box - with the respective nodes the BM-8-36. Prototype of the BM -8-48 chassis car ZIS-6 was made in December 1943, has been successfully field testing, and installation was adopted by the Red Army ".
