Howitzer artillery was developed by improving the systems of PLZ-45 and PLL01 caliber 155 mm, which were developed initially 1990s. These self-propelled guns were in service with the People's Liberation Army of China, and were exported, priemuschestvenno in Saudi Arabia and Kuwait (the latter ordered the supply of 2-parties on any systems 27). But the manufacturer in the process of market research found that modern buyers prefer an old 155-mm system with a barrel length of 45-caliber self-propelled guns with a 52-gauge, since it allows to increment the firing range. In addition, for PLZ52 can be used 155-mm shells, designed to PLZ45, standard NATO ammunition, as Russian artillery shells laser guided. The development of self-propelled artillery PLZ-52 began in the middle of the 1990s. First saw the layout set in 2003.
As the base of PLZ-52 used a 6-stoney tracked chassis, which is very similar to the Russian self-propelled artillery 2S19 (MSTA-S) 152 mm caliber. According to Chinese sources, Type 05 is a hundred percent and China's development is not a copy of the Russian artillery system.
Chinese self-propelled gun PLZ-52 is armed with howitzer type L52 — 155-mm barrel length of 52 calibres, which provides the highest range of up to 53 km of the active-type rockets ERFB-BB-RA, up to 39 km — ordinary shells and up to 20 km — Managed laser-guided missiles.
The gun is equipped with an autoloader providing chambering rounds at different angles of elevation of the barrel, and modular propelling charge, which implements the highest rate of fire 8 shots per minute. With all of this is provided by the rate of fire — 3 shots in 15 seconds and simultaneously undermining the 4 rounds, which significantly increases the intensity of the fire impact on the enemy target. PLZ-52 can automatically set 30 ammunition on board. The barrel is provided with a propellant gas extractor and slotted muzzle brake. The trunk in the transport position is held in place with a lock located on the front sheet. The castle is set manually. The gun in the vertical plane is induced in the range from -3 ° .. +68 °, and the tower in a horizontal plane can be twisted to the full 360 °. The trunk ACS is able to withstand about 2.5 thousand shots.
As an added anti-aircraft machine gun armament is W85 12.7 mm, mounted on the turret and is used to protect the machine in action. In addition, the gun can be used in setting barrage, counteracting the low-flying targets. Ammunition of the gun — 500 rounds of ammunition. ACS commander of a machine gun controls. In addition to each side of the tower in front of it is set in one of four smoke grenade shot.
The construction and protection
The design of the hull and turret self-propelled artillery PLZ-52 is very similar to the PLZ-45 self-propelled guns, different barrel length (45 gauge) for the same caliber of the gun. Construction — welded from steel armor that provides protection against shrapnel and small arms fire guns. The crew of four men ACS commander, driver, gunner and loader. The driver's seat is placed in the front of the chassis to the left of the engine. The driver's seat is equipped with a 3-periscopes, to enter / exit a solid back hatch opening. The tower is located at the rear of the chassis. This assembly increases the stability of self-propelled guns, as in the movement, and the delivery of fire. The internal volume of the tower in comparison with the tower PLZ-45 increased. Cupola is placed closer to the left side of the tower, and on the right side — the hatch for the shooter. The front panel flap commander's panoramic sight set. In the stern of the tower has a pair of small doors, and in the rear of the hull — a huge door opening to the right and started to load ammunition.
Self-propelled artillery installation PLZ-52 is equipped with a 1,000-horsepower engine, aggregated with automatic, which provides good maneuverability mobility. On roads with hard surface ACS PLZ-52 can move at speeds up to 65 km / h, when the supplies travel 450 km.
Torsion bar suspension on both sides has 6 double drive wheels with rubber band. The sixth and fifth wheels are spaced at a greater distance, to ensure rational rassredotachivaniya mass. The steering wheel is in the rear of the hull, leading — in the nose. In addition, each side has three support rollers. To protect the upper part of the suspension are the side skirts.
Self-propelled artillery installation PLZ-52 is equipped with a digital fire control system, which has two-channel thermal sight with a laser range finder. Maybe part of the electrical equipment comes radar meter initial velocity of the projectile. She also has a small reaction time before the first shot that provides outstanding survivability self-propelled guns on the battlefield. Laser fiber-optic gyro navigation system allows autonomous operation without the support of reconnaissance vehicles. Computer technologies simplify and ennoble the exchange of information. The introduction of mental 155-mm shells, such as GS1 and laser homing missile allow ACS PLZ-52 hit on the battlefield different goals. The standard equipment includes self-propelled artillery: the auxiliary power unit, the system of collective security, fire-fighting system with the detection and suppression of explosions.
The main ammunition ACS PLZ-52 to 155-millimeter rounds of separate loading, the creation of which is a Chinese company Norinco:
— High-explosive projectile ERFB / HE having a drive belt and improved aerodynamics;
— High-explosive projectile ERFB-BB/HE gas generator having a bottom, a leading band and improved aerodynamics;
-High-explosive rocket-actively ERFB-BB/RA;
— Star shell;
— Cluster bomb on 72 combat element;
— Smoke bomb.
Can also be used NATO standard 155-millimeter ammunition. Used for high-precision firing guided munitions fitted with a laser-guided. This ammunition was copied from the Russian missile "Krasnopol", which allows you to fire at a distance of 3 to 20 km.
Can be carried out not only hanging fire, and direct fire, as an ordinary gun.
For the supply and delivery of ammunition, of course, can be used transport-loading vehicle from the PLZ-45 howitzers.
At the current time series is the creation of PLZ-52 self-propelled guns. Adopted the People's Liberation Army of China in 2012 was 240 such machines.
