The PLZ45 is a tracked 155mm self-propelled howitzer of Chinese origin. The PLZ45 was developed as a replacement for the aging Type 83 howitzer. Eventually the Chinese armed forces settled on the PLZ05, which is a further development of the PLZ45.

The PLZ45 is based on a new tracked chassis. The engine and drive train are mounted at 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 PLZ45 is fitted with a 45-caliber 155mm howitzer capable of firing NATO standard ammunition, although Chinese ammunition is supplied with it. A semi-automatic loader is fitted and holds 24 out of the 30 rounds that are carried in the vehicle. The maximum rate of fire is 4 to 5 rounds per minute, with sustained fire being 2 rounds a minute. Standard ERFB rounds can be fired up to 30km and base bleed variants up to 39km. For self defense a 12.7mm heavy machine gun is mounted on the turret roof.

The PLZ45 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. No smoke dischargers are fitted.

With its tracked chassis the PLZ 45 has good cross country performance, although its average speed is somewhat limited. The PLZ45 is powered by a 525hp Deutz diesel engine and an auxiliary power unit provides power when the engine is not running.

The PLZ45 is meant for export with the more capable PLZ05 being adopted by Chinese forces. Kuwait bought the entire PLZ45 artillery system with all associated vehicles and ammunition.
