The Saudi Army is deploying its best cannons, the NORINCO PLZ-45 self propelled howitzer (SPH) to bombard Houthi rebels in western Yemen. This is the first time that a modern Chinese SPH has seen combat. While Saudi Arabia has bought primarily American weapons, recent advances in Chinese artillery technology has actually made Chinese artillery more capable in many respects over its American counterparts.
The PLZ-45 is a 33 ton artillery vehicle, with a 6.97 meter long cannon that fires guided and unguided 50kg 155mm shells up to 39 kilometers away (in contrast, the America M109A7 Paladin’s shorter cannon has a 30km maximum range). First developed in the 1980s, the PLZ-45 did not see widespread Chinese service, though its bigger descendant, the 50km ranged PLZ-04, is in widespread PLA service. The PLZ-45 comes with an ammunition supply vehicle that carries 90 shells, as well as sophisticated counterbattery and fire control radars, in addition to forward observation scouts.
