In the middle of the two thousand years, the Ukrainian designers created two original projects of armored vehicles, which involve the repair and re-equipment of the old model tanks. On the basis of the T-64A tanks it is proposed to make heavy-duty infantry fighting vehicles. Such projects, in which the tank “turns” into an armored personnel carrier or infantry fighting vehicle, have already been developed by foreign industry and have proven themselves well. For example, in the armament of the Israeli army from the end of the eighties consists of a heavy armored vehicle "Akhzarit". The technology of this model was based on captured T-55 tanks captured from the enemy.
The BMPV-64 project, created by the Kharkov Armored Repair Plant, implies major changes in the design of the tank, but it uses a significant number of components and assemblies of the base tank. In a heavy BMP, the same powerplant and chassis are used as on the T-64A. The body of the base machine is subject to noticeable changes, but some of its parts remain the same.
The armored body of the infantry combat vehicle BMPV-64 was proposed to be made from the corresponding unit of the T-64A tank. However, the new project involves a major change in the layout of internal volumes. The engine compartment of the BMP was moved to the front of the hull, which made it possible to give the middle and aft part under a single habitable volume. Corresponding changes undergone and undercarriage. In fact, when developing the BMPV-64 machine, the Ukrainian designers turned the base tank's hull backwards and equipped it with a set of equipment typical of infantry fighting vehicles.
The heavy infantry combat vehicle of the new model turned out to be noticeably lighter than the tank, which served as the basis for it. The combat weight of the BMVV-64 is 34,5 tons. Despite its lower weight, the promising BMP has a level of protection comparable to that of the T-64A. Combined reservation of the frontal part of the machine provides protection against armor-piercing sabots 105-mm guns. The onboard armor is able to withstand a hit of an 30-mm projectile. When remaking a tank in an infantry fighting vehicle, additional armor is installed on the bottom of the hull, which increases the level of protection for the crew and the machine’s units. The possibility of crew survival in the explosion of anti-tank mines TM-57. Also, the survivability of the combat vehicle is enhanced by the use of a dynamic protection system. It was argued that, at the request of the customer, the BMPV-64 can be equipped with an active protection system.
The first prototype infantry combat vehicle BMPV-64 retained most of the units of the power plant of the base tank. In front of his body, they installed a 5TDF diesel engine with horsepower 700 hp. With a power density of about 20 HP A promising heavy infantry fighting vehicle can accelerate on a highway to 60 km / h per ton of weight. Fuel reserve is enough to overcome 600 km. If necessary, an 6TD engine with a power of 1000 hp can be installed on the machine, which should accordingly affect its mobility. The undercarriage of an infantry fighting vehicle was borrowed from the T-64А tank with some modifications. As in the case of the base tank, the BMP has six track rollers with a torsion bar suspension on each side. In this case, the guide wheel is transferred to the aft part of the hull, and the drive wheel - to the front, due to the characteristics of the layout of the machine.
For the engine compartment housed the department of management with the jobs of the driver and the commander. The third crew member is behind them and manages the existing combat module. The middle and aft of the hull are given under a large troop compartment. On the benches along the sides of the machine can accommodate 12 fighters with weapons. For landing and landing troops in the stern of the hull provided double door.
The prototype BMVV-64, built in the middle of the two thousandth, carried a remotely controlled combat module. The armament of an experienced BMP consisted of an automatic cannon caliber 30 mm and an 7,62-mm machine gun paired with it. As the main weapons KBA-2 and ZTM-2 cannons (Ukrainian versions of the 2А42) can be used. It was also claimed that, at the request of the customer, the prospective infantry fighting vehicle could receive an additional combat module with remote control, armed with a large-caliber machine gun. Smoke grenade launchers are installed on the combat module and on the stern of the vehicle.
The heavy infantry fighting vehicle BMPV-64 could become the basis for equipment of several classes. The use of units of the T-64A tank allowed the installation of various special equipment and weapons weighing up to 20-22 tons on the BMP. Nevertheless, the only prototype of the perspective vehicle was equipped with a combat module with a cannon and a machine gun.
At the beginning of 2012, there were reports about the creation of a new version of BMPV-64. The upgraded car received an updated body and a number of new systems. At the same time, a high degree of unification with the base main tank remained. Thus, the contours of the armored hull were changed and ennobled, the equipment of the habitable volume changed. BMP received a new hatch for landing and landing troops. On the updated BMPV-64, it consists of two parts, the lower of which in the open position serves as a ramp.
The upgraded BMP received a new weapons complex, located in the turret. It consisted of the 30-mm automatic cannon, machine gun and automatic grenade launcher, as well as the Barrier anti-tank missile system. The four launchers accommodate four transport and launch containers with missiles.
Since the publication of the first information about the machine BPVV-64 she was predicted a great future. It was argued that by the end of the decade, this BMP would be put into service by the ground forces of Ukraine and would gradually replace outdated and obsolete infantry fighting vehicles of other models. Nevertheless, so far, the Kharkov Armored Repair Plant collected only two copies of the promising BMP (one basic version, the second - modernized) and conducted their tests. The difficult economic situation in the country determined the future fate of the project. Ukraine simply does not have the opportunity to begin full-scale re-equipment of old tanks into infantry fighting vehicles.
It should also be noted that the use of the T-64A tank as a basis significantly reduces the export potential of the new machine. T-64A tanks have been preserved only in a few countries: in Russia, Kazakhstan, Uzbekistan and Transnistria. The likelihood that these states will order the modernization of existing equipment from Kharkov tank builders is extremely small. In this regard, an interesting project of converting the main tank into an infantry fighting vehicle is unlikely to give any tangible results.
When modifying the T-64A in the BMPV-64, the propulsion system or the undercarriage did not undergo significant changes, which simplified the process of manufacturing a heavy BMP. Almost simultaneously with the development of the tracked BMP, the designers of the Kharkov Armored Repair Plant began designing a similar-purpose vehicle equipped with a different undercarriage. In the new project BMP-K-64 (also the designation BMPT-K-64 is also encountered) it was supposed to apply the same approach to the creation of technology as in BMPV-64. Ukrainian engineers were going to use the hull, powerplant and a number of other units of the base tank, but at the same time promising BMP was to receive a new wheeled chassis.
As in the previous project, the body of the machine BMP-K-64 is made on the basis of the hull of the T-64A tank with the appropriate modifications. The layout of both heavy infantry fighting vehicles is the same: the engine compartment compartment in the front of the hull and the control compartment behind it, and the rest of the volume is given to the eight-seat troop compartment. As follows from the available materials, both machines are unified for a number of units, including the power plant and internal equipment.
The main difference between heavy infantry fighting vehicles is in their undercarriage. Within the framework of the BMP-K-64 project, Kharkov engineers tried to equip the armored vehicle with a wheel propulsion device. To this end, the 700-strong 5TDF engine mated with a new transmission, transmitting torque to all eight wheels. In the transmission, an individual hydrostatic drive of each wheel with a speed control system was used. The use of a hydraulic actuator made it possible to place pipelines along the sides of the hull, without taking volumes from the troop compartment and the control compartment.
According to reports, the first prototype of the BMP-K-64 machine was designed to test the very possibility of using the wheel chassis on a similar technique. In this regard, the first prototype of the promising BMP did not receive any suspension systems. The rigid attachment of the axles did not allow the prototype to be equipped with a steering system of its usual design. Because of this, as follows from the available materials, control over the course was supposed to be carried out by changing the speed of rotation of the wheels. For this, all wheels were equipped with an individual speed control system.
The installation of the wheel suspension made it possible to significantly reduce the combat weight of the vehicle. BMP-K-64 without installed weapons weighs only 17,7 tons. Such a weight saving in the future can allow to increase the load capacity. The hydraulically driven 5TDF engine provides maximum speed up to 105 km / h. Power reserve - 800 km.
Booking of the BMP-K-64 case is similar to the protection of the BMPV-64. The forehead of the hull withstands hitting 105-mm shells, the sides - 30-millimeter. Declared measures to improve the resistance to mines. For this, the bottom of the car is reinforced by an additional reservation. The unification of wheeled infantry fighting vehicles with tracked vehicles suggests the possibility of using systems of dynamic and active protection. At the same time, however, the statements that the BMP-K-64 can be considered an MRAP-class machine can hardly be considered correct. The demonstrated prototype of a promising heavy infantry fighting vehicle did not have several characteristic features of the MRAP technology. The prototype BMP-K-64, for obvious reasons, did not have a special V-shaped bottom, and was not equipped with special seats that absorb part of the energy of the explosion of the mine.
As a weapon on the first prototype of the BMP-K-64, a remote-controlled turret with a NSV heavy-caliber machine gun was used. Gunner gun located inside the machine body. The capabilities of the power plant and the relatively small weight of the BMP allowed the developers to declare the possibility of using various combat modules with the necessary armament.
By the end of the last decade, it turned out that the BMP-K-64 project is similar to the BMPV-64 not only by the number of units used, but also by fate. Initially, experts highly appreciated the prospects of the new heavy infantry fighting vehicle. Some questions were caused by a specific wheeled chassis without suspension and wheel turning mechanisms, but overall the project looked interesting and promising. However, even a few years after the first show, the BMP-K-64 machine was not able to interest the potential buyer in the person of the Ukrainian Ministry of Defense. For economic reasons, the project is still at the prototype testing stage. The serial production of the new BMP is questionable.
Ideas and reality
Both Ukrainian projects of heavy infantry fighting vehicles look interesting and original. Using as a base for new equipment of old tanks allows you to simultaneously increase the survivability of promising infantry fighting vehicles and reduce their cost, since a large part of the tank's units is not subjected to major changes. Naturally, to create an infantry fighting vehicle with high characteristics, it is required to create and work out some new structural elements, but the prospects of such equipment more than offset all costs.
However, infantry combat vehicles BMPV-64 and BMP-K-64 still exist only in the form of prototypes. Project prospects are limited by two factors: the financial capabilities of Ukraine and poor export opportunities. Due to the nature of the production and operation of the T-64A tanks, only a few countries can order new BMPs, and not all of them will use this opportunity. As a result, interesting projects for the modernization and conversion of old main tanks to new infantry fighting vehicles risk getting stuck at the prototype testing stage for good.
