How does the flamethrower system "Sun"
The greatest effect of its unguided rockets in thermobaric equipment is achieved in mountainous conditions: due to the mutual superposition of air shock waves and their multiple reflection from the surrounding rocks, destruction of soil and stone rubble. The ammunition creates a cloud of explosive mixture and then detonates it, forcing all the oxygen in the cloud to react. After instantaneous detonation, the pressure rises sharply and then drops below atmospheric by about 160 mm Hg. Thus, even if the enemy managed to survive after the explosion, the pressure drop leads to his guaranteed death from rupture of internal organs. High accuracy of salvo fire of the flamethrower system is ensured by direct aiming of the launcher and automated aiming at a target that can be located at a distance of up to 6 km.
Tell me what is his name?
TOS-1A "Solntsepek" is a modification of TOS-1 "Buratino", a heavy multiple launch rocket launcher system based on tank T-72. TOS-1 was developed from 1971 to 1979. The first prototypes on the T-72 chassis were manufactured in JSC "Design Bureau of Transport Engineering" in Omsk. The complex included a combat vehicle (BM) - a launcher with a package of 30 guides on the chassis of the T-72 tank and a transport-loading vehicle (TZM) on the KrAZ-255B chassis. In 1980, the vehicle successfully passed state tests and was recommended for adoption by the Soviet Army.
The "Buratino" system was intended to disable lightly armored vehicles and vehicles, set fire to and destroy structures and buildings, destroy enemy manpower with fragments and a shock wave created by the massive use of unguided rockets in thermobaric and smoke-inducing equipment.
The significant mass of the package of guide tubes with projectiles required a high-carrying capacity chassis, and a small firing range (from 400 to 4500 meters) - a certain level of protection for the entire combat vehicle, which made it heavier up to 46 tons. A package of 30 guides for unguided rockets (NURS) was mounted on the turntable of the launcher. The crew performed all actions to aim the installation at the target without leaving the car - with the help of a sight and electric drives. The trajectory of the projectiles' flight to the target required accurate accounting of the firing conditions and the creation of a special fire control system, which consisted of an optical sight, a laser rangefinder, a roll sensor and an electronic ballistic computer.
From "Buratino" to "Solntsepek"
In 2001, the "Buratino" system was modernized and received the name TOS-1A "Solntsepek". Distinctive features of the novelty are: the number of shells reduced to 24, the firing range increased to 6 kilometers, the KrAZ chassis was replaced with a modernized tracked base of the T-72A tank.
The TOS-1A "Solntsepek" system includes:
- combat vehicle BM-1 ("Object 634B") with a launcher on the T-72A chassis;
- transport and loading vehicle TZM-T (Object 563) on the T-72A chassis;
- NURS MO.1.01.04 or MO.1.01.04M caliber 220 mm.
Fire battery!
The BM-1 vehicle is a multiple launch rocket system. It is equipped with a V-84MS diesel power plant with a capacity of 840 hp. from. at 2000 rpm on the T-72A chassis, a rotating platform with a swinging part, which includes a package of 24 tubular guides for rockets, electric drives and a fire control system. The package of guides is mounted in an armored swinging part, which protects the ammunition from the 32 mm B-7,62 armor-piercing bullet from a distance of at least 620 meters. Aiming the rocking part of the launcher at the target in the horizontal and vertical planes is done by electro-hydraulic drives using a laser rangefinder and a ballistic computer.
Depending on the situation, fire at targets can be made with single and double shots from two barrels. The control of NURS launches is automatic, the duration of a full salvo with paired launches is 6 seconds, with single launches - 12 seconds, and the time of readiness to open fire on a visible target from the moment the combat vehicle stops is 90 seconds. The crew of the vehicle consists of three people: a driver-mechanic, a gunner and a commander.
Shooting is carried out with unguided rockets of caliber 220 mm. The projectiles are designed to deliver a thermobaric mixture, activate it and create excess pressure and a thermal field on the target area. The MO.1.01.04 projectile has a length of 3300 mm and a weight of 173 kg, and MO.1.01.04M is slightly longer and heavier - 3700 mm and 217 kg, respectively. NURS consist of a thermobaric or incendiary warhead, a fuse and a solid-propellant jet engine.
The fire control system includes an optical sight, a laser periscopic rangefinder 1D14, a roll-trim sensor PB2.329.04 (electric, pendulum type) and a specialized electronic digital computing complex MO.1.01.01.03M2. Using a laser rangefinder, the distance to the target is determined with an accuracy of 10 meters. These data are automatically entered into the ballistic computer, which calculates the required elevation angle of the launcher. The roll and trim angle is fixed automatically and taken into account by the calculator.
BM-1 auxiliary armament: RPKS-74 machine gun (1440 rounds of ammunition), AKS-74 assault rifle (300 rounds of ammunition), three RPG-26 anti-tank grenades and ten F-1 hand grenades.
The power drive for guiding the launcher in the horizontal plane is electromechanical, in the vertical plane it is electro-hydraulic. To ensure the accuracy of shooting, the BM-1 is equipped with outriggers and hydraulic friction stoppers with remote electrohydraulic control. The commander's device TKN-ZA is a combined (day and night) electro-optical, binocular, periscope. The rest of the observation devices are both prismatic and telescopic, and the orientation device is a gyroscopic heading indicator gyrocompass GPK-59.
BM-1 is equipped with built-in bulldozer equipment for self-digging, four installations for launching smoke grenades 902 G with a firing range of up to 100 meters and thermal smoke equipment that creates an impenetrable curtain up to 400 meters long. Protection system against weapons mass destruction provides protection of the crew from poisonous substances by sealing the cockpit. A filter ventilation unit with a radiation and chemical reconnaissance device GO-27 purifies the air entering the crew compartment from dust and radioactive substances. The average range of communication with radio stations of the same type is about 20 km. Fire protection system - automatic, triple action.
Get up to charge
Transport-loading vehicle TZM-T is designed for transportation of NURS, loading and unloading of the launcher.
TZM-T is a set of loading and unloading devices located on a tracked base. The vehicle's crew also consists of three people: a driver-mechanic, an operator and a commander. They are armed with an RPKS-74 machine gun (1440 rounds of ammunition), two AKS-74 assault rifles (600 rounds of ammunition), five RPG-26 anti-tank grenades and ten F-1 hand grenades. The lifting capacity of the hydraulic two-mode crane installation is 1000 kg. The charging time of the installation by a remotely controlled electro-hydraulic crane is 24 minutes. Ammunition protection - armored, removable. The power plant, power supply systems, fire extinguishing and protection against weapons of mass destruction of the TZM-T transport-loading vehicle are similar to the BM-1.
Sunstroke
Today, TOS-1A are in service with the 1st mobile brigade of the Radiation, Chemical and Biological Defense Troops (at least four BM-1 units and one TZM-T unit), the 28th separate brigade of the RHBZ in the city of Kamyshin, Volgograd Region (at least two BM-1 units and one TZM-T unit), as well as the 70th separate flamethrower battalion in the village of Razdolnoye, Primorsky Krai (at least two BM-1 units).
In the period from December 1988 to February 1989, two TOS-1 "Buratino" complexes took part in hostilities in the Charikar Valley and in South Salang (Afghanistan) during Operation Typhoon. The tactics of the application consisted in a sudden fire defeat of the enemy, the rapid withdrawal of combat vehicles from a possible retaliatory fire and withdrawal to the points of permanent deployment of Soviet troops. The effect of the use of thermobaric ammunition in the mountains exceeded all expectations. During the battle for the village of Komsomolskoye (Chechen Republic) in 2000, TOS-1 fired at the positions of the militants.
TOS-1A "Solntsepek" is exported to Azerbaijan (6 units of BM-1 on the T-90 chassis were delivered in 2013 and another 6 units will be delivered in 2014), Kazakhstan (3 units of BM-1 were delivered in 2011) and Iraq (several units will be delivered by the end of 2014).
