The PLL05 (or Type 05) is the self-propelled mortar-howitzer system based on a WZ551 6X6 wheeled chassis. The system combines features of the conventional mortar and the howitzer, firing projectiles at both short-range, high-arcing ballistic trajectories and longer-range, less steep ballistic trajectories for indirect fire. The PLL05 has been equipped by the 127th Light Mechanised Infantry Division of the 54th Group Army since 2008. A track-based version of the system is currently in development.

PLL05（或05式）是基于WZ551 6X6轮式底盘为基础的自行迫榴炮系统。系统整合传统的迫击炮和榴弹炮的特点，发射近距、高抛物线弹道轨迹和远距低倾弹道轨迹用于间接火力的射弹。PLL05从2008年以后已经被第54集团军的第127轻型机械化步兵师装备。一种基于履带类型的系统正在发展中。

Programme

The concept of mortar-howitzer was first developed by Russia on the 2S9 NONA-S 120mm tracked SP artillery system, which entered service with the Russian Army in 1981. The same artillery system was later adopted by the 8X8 wheel-based 2S23 NONA-SVK. Although neither system has been exported, China may have managed to obtained an example from a third country in the 1980s and developed its own mortar-howitzer system based on the Russian design. The PLL05 was said to be superior to the 2S9/2S23 in range.

计划

迫榴炮的概念最早被俄国在2S9NONA-S 120毫米履带SP火炮系统上发展，在1981年进入俄国军队服役。相同的火炮系统其后在8X8轮式2S23 NONA-SVK上采用。虽然没有一种系统已经被外销，中国可能在1980年设法从一个第三国家获得一个样品并发展了基于俄国设计国产迫榴炮系统。PLL05据说在射程方面优于2S9/2S23。

The Chinese-designed mortar-howitzer system was first revealed by the NORINCO for the export market in 2001, but the system did not receive any order. An improved variant with a redesigned turret was adopted by the PLA under the designation PLL05. The artillery system can be found in the artillery regiment organic to a light (wheel-based) mechanised infantry division, with 18 vehicles organised into a mortar-howitzer battalion.

中国设计的迫榴炮系统在2001年用于出口市场被北方工业总公司（NORINCO）首次展示，但是系统没有接受到任何定单。一种被重新设计炮塔的改良型被PLA采用命名为PLL05。火炮系统可能成炮兵团建制在一个轻（基于-轮式）机械化炮兵师中被发现，连同18辆车辆。

Design

The PLL05 uses a 6X6 wheeled chassis derived from the ZSL92/WZ551 armoured personnel carrier (APC) with steeled hull. The combat weight is 16.5 tonnes, enabling the vehicle to be airlifted by a Y-8-sized transport aircraft. A crew of four (commander, driver, gunner, and loader) are protected inside the hull with collective NBC protection system.

设计

PLL05采用一个6X6轮式底盘来自ZSL92/WZ551装甲人员运送车（APC）的钢制车体。战斗重量16.5吨，允许车辆被一架Y-8大小的运输机空运。四名组员（指挥官、驾驶员、炮手和装填手）在采用集体NBC防护系统的车体内被保护。

Armaments

The main armament is a 120mm rifled gun, with no muzzle break or fume extractor. The gun has an elevation range of -4°~+80°, and an azimuth range of 360° (in contrast to the +/-35° azimuth range of the 2S23). The maximum range is 9.5km when firing the howitzer projectile, 8.5km when firing the mortar projectile, and 1.2km when firing the HEAT projectile. The artillery could also fire the rocket-assisted mortar projectile, which has a maximum range of 12.8km. The artillery is capable of both in-direct and direct firing. Fire accuracy is attained by a fire-control system, which allows three aiming methods: automatic, semi-automatic, and manual.

装备

主要的装备是一门120 mm火炮，没有采用炮口制退器或抽烟装置。炮管具有-4°~+80俯仰范围，和360的方位范围（与2S23的+/-35°方位范围对比）。当发射榴弹炮射弹时，最大射程是9.5 km；当发射迫击炮射弹时8.5 km；当发射破甲弹（HEAT）时1.2 km；火炮也可以发射火箭助推迫击炮射弹，最大射程12.8 km。火炮能够在两者间接和直接开火。火炮的精度被一套火控系统实现，允许三种瞄准目标方式：自动化、半自动和手动。

While the 2S9/2S23 is manually loaded, the PLL05 is equipped with a semi-automatic loader, which gives a rate of fire of 6~8 rounds/minute (howitzer projectile), 10 rounds/minute (mortar projectile), and 4~6 rounds/minute (HE-AT projectile). The turret is fitted with a cylinder-shape electro-optical device, which may allows the use of smart ammunitions like the Russian KBP Gran laser-guided mortar round. 36 rounds are carried inside the turret and hull.

虽然2S9/2S23是用手装填，PLL05装备一套半自动装填装置，赋予射率为6~8发/分钟（榴弹炮射弹），10发/分钟（迫击炮射弹）和4~6发/分钟（HE-AT射弹）。炮塔安装一套圆筒形光电装置，可能允许使用像俄KBP Gran激光制导射弹一样的聪明弹药。在炮塔和车体内携带36发弹药。

Secondary weapon includes a Type 85 12.7mm anti-aircraft machine gun mounted on the commander copula. There are two sets of smoke grenade launchers in group of three, with one fitted on each side of the turret.

次级武器包括在指挥官舱口上方的85式12.7 mm防空机枪。有两套三组烟幕榴弹发射器，在炮塔两侧各安装一套。

Propulsion

The vehicle is powered by a BF8L413F 4-stroke, 8-cylinder, turbo-charged, air-cooled diesel engine, which produces a standard power of 235kW (320hp) at 2,500rpm. The vehicle is capable of a maximum speed of 85km/h on paved road and 8km/h when afloat. Two propellers are fitted at the rear of the vehicle for swimming.

推进

车辆的动力由一台在2,500 rpm时功率235 kW（320 hp）的BF8L413F 4-冲程、8-缸、涡轮增压、风冷柴油发动机提供。车辆的最大能力是85 km/h铺面道路速度和8km/h的浮渡速度。用于浮渡的二具螺旋桨被安装在车尾。
