Development of heavy machine guns at a particularly powerful ammunition caliber 14.5mm, originally created in the USSR for antitank guns, was launched in 1942, according to numerous requirements of the troops. The main purpose of such a heavy machine gun were to be the fight against lightly armored enemy equipment (light tanks and armored personnel carriers), skinned and ground equipment by enemy aircraft. In 1944 it was decided to develop the design of a machine gun, as proposed by Vladimirov, but lapping machine guns and equipment for a prolonged and adopted a large-caliber machine gun was adopted only in 1949, a variant of an infantry machine gun on a wheeled machine Harykina (under the symbol PEP – KPV machine gun infantry Vladimirova system) as well as anti-aircraft variant several land and marine plants that had one, two or four machine gun. In 1955 appeared the tank version of the machine gun KPVT, who succeeded in producing CPV / PCU and used as a vehicle for weapons (BTR-60Д, BTR-70 BRDM), and anti-aircraft machine gun mount LSD-1, ZPU-2 and ZPU- 4. Anti-aircraft variant CPV was used during the hostilities in Vietnam, in addition, these guns were widely used by Soviet troops in Afghanistan and during the Chechen campaign. Copies of the CMP machine guns produced under license in Poland and China.
Until recently, the KPV heavy machine gun was the most powerful weapon in its class (less than 20 mm caliber), but a few years ago, China had developed its own version of a machine gun chambered 14.5h115 original design. Thanks to the powerful cartridge with armor-piercing bullet weighing 60 grams and nachanoy speed 1030 m / s (muzzle energy of the order of 32 000 joules) CPV penetrates 32mm of steel armor at a distance of 500 meters and 20mm armor at ranges of 1000 meters.

KPV heavy machine gun CMP-14, 5 uses automation to energy use efficiency in the short course of trunk. Locking barrel when a shot by rotating clutch attached to the gate, the inner surface of coupling has lugs in the form of segments perryvistoy thread included a rotation in mesh with corresponding lugs on the barrel breech. Rotation of coupling occurs when the interaction poepechnogo pins with shaped cutouts in the receiver. Quick-change barrel, enclosed in a perforated metal cover and remove from the body of a machine gun, along with the housing, which on the casing has a special handle. Stock is made from a metal strip with closed link, collected from nerassypnyh pieces for 10 rounds each. Connecting pieces of tape carried by the cartridge. Standard output capacity tape – 40 rounds for the PCU and 50 – to KPVT. Submission of tape cartridges into the barrel is carried out in two steps – first special Extractor for bolt recoil ejects the cartridge from the tape, after which the cartridge is reduced to the chambering line and reel shutter be sent to the trunk. Release of spent cartridges carried down and forward through a short pipe to the receiver; shooting sleeve is pushed out of its restraints grooves on the mirror shutter next patron or a special lever – rammer (for the last cartridge in the tape). Shooting is conducted with an open shutter only automatic fire. The trigger mechanism is usually located on the machine or installation in an infantry version of the controls on the machine includes two vertical grip and shutter button between them in a tank machine gun equipped with a remote elektrospuskom.

In the infantry version of the machine gun mounted on a wheeled machine with a split trail or on the machine, tripod, a zenith – in various settings with drives guidance and special sights. At the armored vehicles KPVT usually used as a primary weapon and armored reconnaissance vehicles, when installed in a tower. In a series of experimental heavy tanks developed immediately after World War II KPVT supposed to install as coaxial gun, or as a zenith on the tower.
