The PLZ45 is a Chinese self-propelled gun intended for export. In the 1980s, China began reducing its military spending to focus on economic development. To keep pace with military technology, China developed equipment for export alongside equipment intended for the domestic market. Thus, in 1986, the development of an export self-propelled gun equipped with a 155mm gun based on the Austrian GHN45 howitzer began. The first prototype was completed in 1988 and soon showcased at an international defense exhibition in Beijing. The first live-fire exercises and tests in the hot desert climate took place in 1989. Based on these results, changes were made to the vehicle’s design by 1995. Although initial attempts to sell the self-propelled gun began a year earlier, the first contract was not signed until 1997, with deliveries beginning in 1999. Over time, the PLZ45 entered service with the militaries of Kuwait, Saudi Arabia, Ethiopia, and Algeria. Additionally, a small number of vehicles were tested by the PLA.

The PLZ45 was introduced in Update 2.59 "Sky Odyssey". Among similar self-propelled guns equipped with 152–155 mm guns, the PLZ45 stands out for its BEA1-155 semi-armor-piercing shell, which enables it to destroy most targets at silhouette range. HE-VT shells are also available for engaging aircraft and armored vehicles. The presence of smoke grenades and a heavy machine gun for the commander is a welcome feature. However, it is otherwise a slow self-propelled gun with a large size and weak armor.
