Type 05 / PLL-05 120mm Howitzer / Mortar - Design

Originally, this self-propelled howitzer was a type of artillery that was loaded from the muzzle and fired with low initial velocity, relatively curved trajectory. In large-scale wars, it is the main firepower to suppress the enemy; while mortars have a parabolic trajectory. The advantages of light weight and fast rate of fire can hit targets that ordinary artillery cannot attack. Therefore, it plays an important role in mountain combat, airborne combat, urban street combat and landing combat, and can provide the most timely fire support for infantry. Ordnance experts organically combined the two to form a new type of artillery-mortar howitzer.

Because it appeared early, it has been gradually replaced by other long-range, high-power artillery, and slowly went downhill. But the advanced mortar system jointly launched by Northern Europe and Sweden this year has brought a new concept to the world, so the United States also included this weapon in the US "Future Combat System" candidate weapon list.

In modern battlefields, howitzers are undoubtedly the main force supporting firepower, while mortars have the advantages of curved ballistics and light weight. They play an important role in mountain operations and other occasions. They can provide the most timely fire support for infantry and combine the two. The mortar is formed, and the PLL-05 120mm self-propelled mortar developed by China is such a weapon. The gun has the advantages of mortars and howitzers, and has good road maneuverability. It is mainly used to equip rapid reaction troops, airborne troops and light armored troops.

The appearance of the gun is similar to the Russian 2S23 self-propelled mortar system, but the barrel of the rifled gun is longer than the latter, which is very similar to the 120mm 2A80 mortar of the 2S31 self-propelled mortar system.

The development of history of the Soviet Union's howitzers launched 2B16, 2S9, 2S23, 2S31 and other classic products, while other countries have not developed this kind of artillery. 2S23 was introduced to China, for example, with the Chinese self-developed PLL-05 self-propelled 120mm howitzer. The PLL-05 type uses 66 wheeled chassis, with a combat weight of two tons greater than the Russian 2S23, but this does not affect the airlift mobility. Although the volume looks smaller than the 2S23, the Chinese howitzer carries 36 rounds, 6 rounds more than the 2S23. The Chinese themselves howitzer turret to the rear carries the supplementary ammunition, with protection stronger than the 2S23. With the 2S23 the direction of fire of 35 degrees, the level of fire as -4 degrees - +80, while the PLL-05-type force and the level of fire howitzer is the same. But the direction of fire reaches 360, so fire response capability is significantly higher than the other, as is the range, due to the PLL-05-style body tube to be longer, and thus effectively combat scope should be broad.

PLL-05 adopts a semi-automatic reloading method, and its aiming and combat mode can be selected from automatic, semi-automatic or manual mode according to needs, so it has a strong ability to continue high-speed shooting. In addition, the PLL-05 120mm self-propelled mortar is also equipped with guided artillery shells, which can accurately strike high-value targets hidden on the reverse slope of the mountain that cannot be reached by conventional artillery.

This PLL-05 120mm self-propelled mortar is equipped with an advanced two-way stabilizer, and is also equipped with a night sight, so this howitzer has a very good attack on moving targets even at night. At the same time, the two sides of the turret are also equipped with X groups of smoke bombs. This design allows it to conceal itself well in war. The car is also equipped with three-defense devices, which can be carried out under special conditions.

The PLL-05 120mm self-propelled mortar can shoot at a long-distance target in an intermittent shooting mode, launching anti-personnel blasting grenades or mortar shells, and then switch to a direct shooting mode within a few seconds to approach the front The tanks and armored vehicles in the position are shooting, so that changing the way of shooting can catch the enemy by surprise. The PLL-05 self-propelled mortar has a maximum range of 9.5 kilometers for high-explosive grenades, a maximum range of 8.5 kilometers for mortar shells, and a maximum range of 1.2 kilometers for armor-piercing shells. The semi-automatic loading method is adopted, so it can always maintain a high rate of fire: 6-8 rounds/min when launching high-explosive grenades, 10 rounds/min when launching mortars, and 4-6 rounds/min when launching armor-piercing rounds.

Aiming and combat modes: automatic/semi-automatic/manual, loading mode, semi-automatic, a 12.7mm QJC88 high-level dual-purpose vehicle-mounted machine gun is mounted on the turret, with 500 rounds of ammunition and a maximum rate of fire of 600 rounds/min. The artillery is equipped with an advanced two-way stabilizer and a night sight, so that it has the ability to attack moving targets at night and during travel. X sets of smoke bombs are installed on both sides of the turret to conceal oneself in combat, and the vehicle is equipped with three-defense devices that can fight under special conditions.

The self-propelled mortar can shoot at long-distance targets in an indirect shooting mode, launching anti-personnel blasting grenades or mortar shells, and then switch to direct shooting in a few seconds to shoot at tanks and armored vehicles that are approaching forward positions.

The vehicle has good specifications. It uses a 320-horsepower engine and relies on two propellers installed on both sides of the rear of the vehicle. Other standard configurations include: front 4-wheel auxiliary power steering, nuclear, biological and chemical protection system, and central tire pressure adjustment system. On both sides of the turret, triple-mounted electronically controlled smoke bomb launchers are installed. The gun has an advanced fire control system that can aim and fire in three ways: automatic, semi-automatic and manual.

The gun is a fully enclosed turret with a welded structure that can rotate the turret 360 degrees. Can fire mortars, grenades and anti-tank grenades. The self-propelled mortar is also equipped with a new type of ammunition, including standard high-explosive mortar rounds, stabilized tail wing high-explosive anti-tank grenade, which can effectively attack light armored targets at a distance of 1.5 kilometers, and can penetrate 90 mm of traditional steel Armor.

The aiming and combat modes of the gun can be selected as automatic, semi-automatic and manual according to needs. The artillery is equipped with a semi-automatic loading system, equipped with direct aiming and shooting and indirect aiming and shooting two types of sighting devices.

Using a 6X6 wheeled chassis, the combat weight is close to 16.5 tons, and the ammunition carrying capacity is 36 rounds. The turret is at the rear of the car body, and its fire response capability is significantly higher than that of the opponent.

In terms of range, the mortar shell is 8.5 kilometers and the armor-piercing shell is 1.2 kilometers. Chinese self-propelled mortars use semi-automatic loading methods, so they can always maintain a high rate of fire: 6-8 rounds per minute for high explosive grenade, 10 rounds per minute for mortar rounds, and 4-6 rounds per minute for armor-piercing rounds/minute.

The artillery length 6.7 m, width 2.8 m, height 2.8 m. The gun battle the whole weight of 16.5 tons, maximum road speed of 80 km / h, maximum travel 500 kilometers. PLL-05 artillery system is equipped with a 120 mm caliber rifled gun, according to the war needs, fired mortar shells, grenades and anti-tank grenades and cluster bombs, the vehicle ammunition capacity is 36 rounds. When used as a howitzer, capable of firing high-explosive grenades maximum range of 9.5 kilometers, the front can be used against enemy targets, may be relatively quick to distance target shooting; when used as mortar, it can fire shells with a range of 8.5 km.

It can be used to combat the enemy hidden in front of a shelter is not observed or target; when used as an anti-armor fire, it may emit HEAT effective distance of 1.5 kilometers, which can effectively against light armored targets; while when used as a multi-purpose ammunition, but also launch cluster bombs to penetrate 90 mm thick steel armor, the enemy's light armored vehicle staging ground targets and pose a great threat. PLL-05 howitzer forcing a secondary weapon for the Type 85 12.7 mm caliber machine gun can be used as self-defense and air defense.

In addition, PLL-05 has semi-automatic loading thanks to the way its targeting and combat modes can be selected automatic, semi-automatic or manual mode, so the sustained rapid firing ability. In addition, PLL-05 self-propelled 120mm howitzer is also equipped with forced-guided artillery shells, it can reach the precision strike conventional artillery hidden in the mountain slope against high-value targets. Moreover, this wheeled themselves forced howitzer equipped with advanced two-way stabilizer and night sighting device, capable night in the road between the moving target shooting, the gun can greatly improve the PLA's mountain warfare capability. In addition, the ability to sacrifice two guns very well, traveling by water on both sides mounted on the rear two propellers, water maximum speed of 8 km / h.

It is reported that, PLL-05 wheeled self-propelled howitzer, compared with conventional mortars, mobility and range have made considerable progress, can be equipped to support fire use as a battalion level. The gun will be the main equipment of the PLA rapid reaction force, airborne troops, light armor and mountain warfare and amphibious warfare units, etc., as the backbone of fire battalion level, making the PLA infantry combat detachments been greatly enhanced firepower. Especially in the future landing rough seas fleet, if incorporated into this gun, you can make it fully song shoot and direct the power of the enemy shore beachhead fortifications and hidden enemies full coverage, is the future of amphibious landing operation indispensable fire support force.
