The PLZ05 is a modern tracked 155mm self-propelled howitzer of Chinese origin. It is a further development of the PLZ45 which was found not yet capable enough for Chinese service. Development took place in the early 2000's and certification took place in 2005 and 2006.

The PLZ05 is based on a modified tracked PLZ45 chassis. The drive train is mounted in the front and the fully enclosed turret is fitted at the rear. The crew of five consists of a commander, driver, gunner and two loaders. The turret houses a fully automated loading system which is derived from the Russian 2S19 Msta.

The PLZ05 is fitted with longer 155mm howitzer than the PLZ45. A length of 52 or 54-calibers is quoted. As a result longer ranges of over 50km can be achieved with special types of ammunition. Unlike the PLZ45 the PLZ05 is not fitted with a semi-automatic loader. A fully automatic loader similar to the Russian 2S19 is fitted. This doubles the maximum rate of fire to 8 to 10 rounds per minute. For self defense a 12.7mm machine gun is mounted on the turret roof.

The PLZ05 is operated under full armor protection. The steel armor gives protection against small arms fire and shell splinters. NBC and fire suppression systems are fitted. A total of 8 smoke dischargers are fitted.

The PLZ05 is based on a slightly modified chassis of the PLZ45. The spacing between the road wheels is somewhat different but the rest is similar. An unspecified diesel engine is fitted and an auxiliary power unit provides power when the engine is not running.

The PLZ05 is only used by the Chinese armed forces and is to become the standard heavy self-propelled howitzer in Chinese service. The PLZ05 is only used by armored units. Unless major deficiencies are found the PLZ05 is expected to remain in production and service for many years.
