PLL-01

From Wikipedia, the free encyclopedia

PLL-01, also known as the WAC-021, is a type of 155 mm howitzer designed by Gerald Bull and built by Chinese defense manufacturer Norinco.

History[]

In 1980s, Chinese military industry acquired the license to produce GHN-45 howitzer from Noricum, subsidiary of the Austrian company Voest-Alpine, whom developed CHN-45 based on the design of the GC-45 howitzer. GHN-45 (Gun, Howitzer, Noricum) featured several improvements to the original GC-45, such as better ammunition and fire control systems. Due to the design improvement, GHN-45 had considerably longer ranges than other 155 mm cannon systems used by NATO and Western countries. This capability initially caused worry for allied forces in the Persian Gulf War.[1] The designer Gerald Bull was contacted by China to develop his work for them, which he agreed. China also purchased extended-range ammunition technology from him.[2]

The Chinese production designation of the GHN-45 is WAC-021 and PLL-01,[3] which entered service in 1987.[4][5] China continue to acquire and develop other technologies for the PLL-01, such as precision guided projectiles GP1. China also mounted the PLL-01 onto an indigenous-designed tracked chassis, resulting in the PLZ-45 (also known as the Type 88) and an ammo-carrier based on the same chassis. The PLZ-45 did not enter service with the People's Liberation Army Ground Force because China still use the doctrine developed for the Soviet-standard 152 mm ammunition at the time. However, two major batches of PLZ-45s were sold to the Kuwaiti in 1997 and to Saudi Arabia in 2008.[6][7][8]

Design[]

The PLL-01/WAC-201 is license-produced variant of the Austrian NORICUM GHN-45 howitzer, thus two systems are compatible in the choice of ordnance. The NORINCO Type WA-021 has an auto-frettaged barrel 45 calibers long, fitted with a multi-baffle muzzle brake, which has an efficiency of 30 percent. A screw-type breech mechanism opening to the right is employed and the chamber volume is 22.95 liters. The rifling employs 48 grooves with a twist of 1 in 20 calibers, and the grooves are understood to be three times deeper than the rifling depths found on comparable Western 155 mm designs.[3] The weapon also accepts locally made Chinese ammunitions and NATO-compatible ammunitions.[9]

Deployment[]

The weapon system is used by People's Liberation Army Ground Force, Iranian army as towed artillery.[2] The PLZ-45 self-propelled howitzer was sold to Kuwit, Saudi Arabia and Algeria.[6][7][8]
