The PLZ-45 or Type 88 is a 155 mm self-propelled howitzer designed by Su Zhezi of 674 Factory, and developed by Norinco, 123 Factory (Heilongjiang Hua'an Industry Group Company), 127 Factory (Tsitsihar Heping Machine Shop), 674 Factory (Harbin First Machine Manufacture Limited Company) and the Beijing Institute of Technology in the early 1990s for the export market. It is based on Norinco's Type 89 (PLL-01) 155 mm/45-calibre towed gun-howitzer.[2][3]

The PLZ-45 self-propelled howitzer is used by the Chinese People's Liberation Army, the Algerian People's National Army, the Kuwait Army and the Saudi Arabian Army.

History

Noricum, the arms division of the Austrian steel company Voestalpine, purchased the design rights to the GC-45 howitzer after Space Research Corporation moved to Brussels. They made a number of detail changes to improve mass production, resulting in the GHN-45 (Gun, Howitzer, Noricum), which was offered in a variety of options like the APU and fire-control systems. Once out of prison, Gerald Bull was soon contacted by China.[4]

The PLA also used the Noricum version, producing it as the PLL-01, which entered service in 1987.[5][6] They also mounted it on a locally designed tracked chassis to produce the PLZ-45 (also known as the Type 88), along with an ammo-carrier based on the same chassis. The PLZ-45 did not enter service with the PLA primarily because their existing artillery was all based on Soviet-standard 152 mm ammunition. However, two major batches of PLZ-45s were sold to Kuwait and Saudi Arabia.

Design

Armament

Operated by a crew of five (commander, gunner, two loaders and a driver), the PLZ-45 is armed with a 155 mm, 45-calibre main gun, with a semi-automatic loader and an electrically controlled and hydraulically operated ram that enables projectile loading to take place at any angle of elevation with the charge being loaded manually. The turret has an elevation of +72 to –3 degrees with 360 degree traverse.[2]

Secondary weapons include a roof-mounted W-85 heavy machine gun and two sets of four-barrel smoke grenade launchers on the turret's side.

Ammunition is stored at the rear of the turret. A total of 30 rounds for the gun-howitzer and 480 rounds for the machine gun are carried on board. 24 howitzer rounds are carried in the loader and 6 rounds on the right side below the loader.

The fire-control system of the PLZ-45 includes an automatic laying system, optical sighting system, gun orientation and navigation system, and a GPS receiver.[2][3]

Munitions

The PLZ-45 howitzer fires a range of Extended Range Full Bore (ERFB) ammunition, including High Explosive (ERFB/HE), Base Bleed High Explosive (ERFB-BB/HE), ERFB-BB/RA, ERFB/WP, ERFB/Illuminating, ERFB/Smoke, and ERFB-BB/Cargo.[2][3]

China obtained the Russian Krasnopol laser-guided projectile technology in the 1990s, and successfully developed its own 155 mm laser-guided ammunition. Designed to defeat armoured vehicles and weapon emplacements, the projectile has inertial mid-course guidance and semi-active laser homing. The projectile has a range of 3–20 km (1.9–12.4 mi), and can hit a target by the first shot without registration.[2][3]

Combat

A standard PLZ-45 battalion consists of 3 batteries, each with 6 PLZ-45 self-propelled howitzers (SPH) and 6 PCZ-45 ammunition support vehicles (ASV). Each battery has a battery command post and 3 battery reconnaissance vehicles (BRV), both of which are based on the Type 85 APC. These are supported by W653A armoured recovery vehicles, 704-1 artillery locating and fire correction radar, 702-D meteorological radar, and fire support maintenance vehicles.[3]

Propulsion

The PLZ-45 self-propelled howitzer is powered by a 525 hp Deutz turbocharged air-cooled diesel engine, giving a max road speed of 55 km/h (34 mph).[7]

Armour and protection

The armour of the PLZ-45 self-propelled howitzer protects against small arms fire and artillery shell splinters. It is fitted with NBC protection and automatic fire suppression systems.[2]

Operational history

In April 2015, the Saudi Arabian Army used the PLZ-45 for shelling Houthi rebels along the Saudi Arabia–Yemen border during the Saudi Arabian–led intervention in the Yemeni Civil War.[8] This was the first time the PLZ-45 has been used in combat.[9] In late 2015, Kuwait sent an artillery battalion to Saudi Arabia to assist its Saudi ally against the Houthis.[10]
