Modernization of BMP-1 - JSM "Cleaver"

The Kliver BM as a modern weapon system was specially developed in the 90s of the last century for the rapid modernization of the BMP series vehicles, increasing the service life of the vehicles due to a sharp increase in fire potential, power and capabilities of the onboard weapon system. The total number of serial vehicles is currently about 20 thousand BMP-1 vehicles, half of which were exported at one time. Moreover, many of them are still in service in more than 40 countries around the world. Only in Russia there are about 9000 of them. The last BMP-1 left the factory in 1981.
Standard armament and control equipment make it possible to hit ground targets at a distance of up to 1.3 kilometers in daylight and up to 0.5 kilometers in the dark with gunfire and hit targets up to 3 kilometers with ATGM. The ammunition used has already become insufficiently powerful to hit modern targets, and the lack of modern equipment makes firing from the BMP-1 weapons ineffective. However, the large potential for modernization and the "Soviet" quality of the BMP-1 chassis make these vehicles an excellent base for modernization.
Therefore, work was started on a modular weapons system to increase the combat potential of the vehicle. The Kliver MBT, which houses missile and cannon weapons, is complemented by a modern automated fire control system. In addition to the BMP-1, the module is ideal for upgrading many lightly armored combat vehicles, upgrading/modifying small combat surface ships, and installing them on stationary platforms.

The first public appearance of the JSM “Cleaver” is the 1996 year, on the 850 anniversary of the city of Tula. It was installed on the working model of the BTR-80 vehicle. Due to the fact that the module is designed to be placed on the BPM-1, a shoulder strap from the BMP-80 is welded on to the BRT-1, where Clever was installed. The full name of the module is TKB-799 “Cleaver”. In 1998, he is being tested at BMP-1 in Kubinka. A year later, two BMP-1 vehicles with the “Kliver” modules installed were presented at the IDEX'99 international exhibition in the UAE.
WMO Cleaver:
- A turret with mounted 4 anti-tank guns, an 30 mm gun, a machine gun and a set of sighting devices;
- ammunition supply system;
- ammunition in a turret deprivation;
- a place for placing the gunner-operator.
The module has a single execution and consists of:
- 30 mm automatic guns "2А72", which are regularly installed on the BMP-3;
- anti-tank missile complex with laser-guided "Cornet";
- machine gun caliber 7.62 mm type PKTM.
Module ammunition consists of:
- 4-x missiles for the Kornet anti-tank systems;
- 300 ammunition for 30 mm guns 2А72;
- 200 ammunition for machine gun.

Due to the low landing of the tower on the machine body, it receives additional security when opposing the enemy. Missile launchers with guided missiles mounted on a single axis with a machine gun-gun unit. The tower itself is designed as a welded structure: of armor plates with different installation angles. Sights - a thermal imager and a laser pointing device "1K13-2". The head part of the sight is made to the left of the tower, slightly behind there is a hatch loading ammunition. The anti-tank missile launchers are mounted on guides to the right of the gun. Vertical guidance is the same for the entire weapon system. The barrel of the gun has a special frame to improve the rigidity of the gun and increase the accuracy of fire.
The module allows firing at the enemy at any time of the day with the entire weapon system, both from a stationary position and while moving on land and water. Targets are lightly armored ground and surface objects, low-flying aircraft and enemy manpower. The installed equipment ensures rapid detection and recognition of enemy objects in daylight and darkness, determining the distance to the target, calculating the necessary parameters for firing, directing the weapon system to the target and monitoring the operability of the fire control system. In terms of its fire characteristics, the Kliver OBM has superiority over the American M2 Bradley module and the BMP-2 weapon system.
