PCL-181 155mm self-propelled howitzer

PCL-181 vehicle mounted howitzerThe domestically produced new 181-type 155mm vehicle-mounted self-propelled howitzer has a wide front cab, and 6 members of the artillery squad can sit in it. The cab is protected by steel plates. The front and side windows are bulletproof glass to protect the gunner from shrapnel and bullets. In 2006, China successfully developed the SH-1 type 155mm truck gun and the SH-2 type 122mm truck gun. These two types of truck guns were mainly for foreign markets, and the comprehensive technical performance belongs to the international intermediate level.

China's new domestic 155mm truck gun was exposed in October 2017. As early as April 2015, there were several photos of suspected new 155mm trucks on the Internet. Some netizens analyzed that they should be used by the military for self-use. Comparing the new domestic car gun that had been exposed by netizens two years ago with the new gun, the conclusion is that the two are strikingly similar.

It is reported that the code of this new artillery is PCL-181 [some sources report PLC-181] truck artillery delivery system, which is an important part of China's current mechanized units to strengthen firepower, and is also an enhanced upgrade version of China's 122mm truck gun. The addition of the 155mm truck cannon will greatly enhance the firepower of China's mechanized units.

China's PCL-181 155mm truck gun uses China's latest 52-caliber 155mm gun. This gun uses a variety of new technologies, including electroslag remelting barrel smelting technology and gun barrel self-tightening process. The gun has a very long range and a stable launch state.

The cannon can reach 40 kilometers in the case of launching conventional grenades, and can reach a range of up to 45 kilometers. The bottom-range extended range projectile can reach a range of 50 kilometers, and with the rocket extended range shell the farthest range of up to 72 kilometers can be reached.

It is worth mentioning that the length of the guided rocket extended shell launched by China's 155mm artillery is 2 meters. It needs to be filled into the cannon in a special way. After the gun is opened, the rocket extended range can be started for a while, and the Beidou satellite can be used for guidance. Remote precision strike.

China's PCL-181 uses Taian GM's 6X6 off-road truck chassis, which has strong passing ability and off-road capability. The gun body part is located at the rear end of the truck. The truck part is equipped with fire control radar and Hydraulic type bombing device, the gun itself also has its own adjustment ability. As a result, the PCL-181 is highly adaptable for launching on many complex terrains.

Based on the information of China's weapon industry, the gun is a self-propelled large-caliber vehicle-mounted jug with a caliber of 155 mm. It adopts FAW's new generation 6X6 off-road truck chassis, oil and gas suspension, and good off-road maneuverability. The gun is 52 times the caliber, the same as the 05A 155 mm crawler-type self-propelled howitzer, with a powerful fire output. At the back of the gun, there is a large auxiliary raft. Usually, the barrel and the gun body are placed on the vehicle. When the battle is over, the hydraulic device is turned over. The liquid pressure type high and low machine and the balance machine are used, and the hydraulic transfer device is used.

The overall structure of the PCL181 vehicle-mounted howitzer is divided into four main parts: 1. Firepower system, which includes recoil, cradle, anti-recoil device, high-level machine, steering machine, racking and auxiliary ammunition transporter, etc.; 2. Chassis system, including cab, engine, radiator, transmission shaft, tire rim, suspension system, ammunition box and frame, etc.; 3. Hydraulic support system, including jack, seat plate, large frame and large frame cylinder, etc. 4. Fire control and electronic systems, including fire control computer, strapdown inertial navigation device, satellite positioning device, gunner mission terminal, sight, sighting hand display, chemical temperature measuring device, muzzle velocity radar, vehicle communication and radio, etc.

The vehicle chassis adopts the military 30-ton (PCL181 combat weight is as much as 27 tons) 6 6 cross-country high-mobility heavy-duty vehicle chassis with a "flat-head" structure. The reason for the "flat head" structure is to make the driver's cab and the muzzle as far apart as possible to minimize the impact of the muzzle shock wave on the driver's cab when the artillery is launched. In order to improve the strength of the cab, Southern Institute of Technology has completely redesigned the cab, using a frame-type steel beam welded reinforcement structure, and the surface is covered with armored steel plates to ensure the rigidity of the cab and the protection of the occupants in the car. There are two passenger doors on both sides of the cab. Both the front windshield and the passenger door are bulletproof glass, which can effectively protect against light weapons bullets.

The recoil of the fire system is composed of a muzzle brake, a barrel and a gun tail. The muzzle brake is still cylindrical, three-sided hole impact type. The equipped 52-caliber barrel is exactly the same as that of the PLZ05 self-propelled howitzer, and the ammunition is universal. Its 155mm barrel takes into account the three indicators of range, density and life, and its performance is very good. In order to be compatible with the cartridge propellant, the gun adopts a semi-automatic vertical wedge type breech block, which has a rapid opening and closing bolt, and does not require an additional opening and closing bolt device and a "breathing device", which can significantly increase the rate of fire. There are two sets of manual and electromagnetic firing devices on the anti-dangerous plate on the left side of the gun tail, which can realize remote firing or "fire-collecting" firing with the help of artillery command system.

A set of muzzle velocity radar is installed on the protective plate of the anti-recoil device of the artillery cradle to measure the initial velocity of the projectile. A set of laser gyro strapdown inertial navigation device is installed behind the right side of the cradle, which is protected by a protective box, which is used to directly measure the attitude of the artillery barrel in the horizontal system of the earth and the change of the gun vehicle heading, so as to achieve fast gun adjustment. High precision and automatic review.

The left rear part of the cradle is the position of the aiming hand. It is equipped with an independent line-of-sight swing type mechanical digital display sight. Since the high and low pitch is realized by a liquid pneumatic high-level machine, the aiming hand can manipulate the hydraulic pressure during manual operation. Crank-handle high-low machine and mechanical hand wheel steering machine for aiming ( SH15 can also use an automatic operating handle to adjust the gun in order to meet the needs of foreign trade. PCL181 should not have such a device ).

Compared with the 155mm car howitzer such as Caesar of France, the advantage of the Chinese 155mm gun is that the direction of the shooting can reach 360, and the range of shooting is much higher than other car howitzers, even if it is 30 degrees on the front and left, affected by the cab. It is still able to reach high and low shots of around 20 degrees to 70 degrees.

Compared with similar products in Europe and America, China's PCL-181 should be similar to the French Caesar truck. From the design point of view, China's PCL-181 and Caesar are tactically consistent.

China's previous plateau troops used a large number of 122mm trucks as fire support weapons, but compared with the US M777 155mm ultralight guns, they were not only limited in caliber in terms of firepower, but also fell in the down range in terms of range and motion. Therefore, the emergence of China's PCL-181 155mm artillery is to make up for these shortcomings.

The artillery brigade of the Eastern Theater Army stationed directly opposite Taiwan is equipped with a 181-type 155mm vehicle-mounted howitzer. It is high-profile. The whole process was broadcast live. It was also filmed with drones, even the artillery brigade station. It is speculated from the number of domestically-made new 181-type 155mm vehicle-mounted self-propelled howitzers that the artillery brigade was replaced with a howitzer battalion. If the entire battalion is full, there should be 27 155mm vehicle-mounted self-propelled howitzers. It is speculated from the public information that the artillery brigades of the Tibet and Xinqiang Military Regions of our army and the artillery brigades and howitzers battalions of the armed forces of the eastern theater of the army have been installed with the new 181-type 155mm vehicle-mounted howitzers.

The PCL181 vehicle-mounted howitzer has high firepower performance, long range, strong fire coverage and firepower maneuverability, and the gun is easy to maintain, its life cycle cost and weight are much lower than that of a crawler self-propelled howitzer. At present, it is mainly equipped with the group army The artillery division (brigade) performs long-range suppression fire strike missions, and will also support battalion (company) command vehicles, reconnaissance vehicles, weather radars, and reconnaissance and school radars. Utilizing a highly automated fire control system and a command and control system, the gun can automatically complete a series of actions within 1 minute, such as receiving instructions, resolving aiming, adjusting the gun, and firing the first shot, and can quickly evacuate the battlefield.

As China's new type of artillery is successively in service, China, as a large artillery country, has already achieved a curve overtaking in advanced western countries.
