Ivan's deadliest AAA weapon at the front lines: the ZSU-23-4 Shilka:
The ZSU-23-4 SPAAG in World War III
The ZSU-23-4 “Shilka” (as known to Soviet and Soviet-allied users, the “Zoo” to the Allies) was the most common, and feared, Soviet self-propelled antiaircraft gun that saw service in the Third World War. First seen in combat in the 1973 Yom Kippur War, and then in Vietnam during the NVA's final offensive in 1975, the system was widely respected in Western and Western-allied air forces in the years leading up to the war, and that respect continued during the war. Widely used by the Soviets as well as their allies in both theaters in North America, the system maintained its reputation for lethality, and modernized versions of the system still serve in the former USSR, as well as in former Soviet clients to this day.
Variants:
ZSU-23-4: Preproduction and initial production versions. In Soviet service beginning 1964. Tracked vehicle but not amphibious. Crew of four (Commander, Gunner, Driver, Radar Operator). Four AZP-23 23-mm automatic cannon with 2,000 rounds, RPK-12 radar with detection range of 12 miles. NBC system fitted as standard.
ZSU-23-4V: Improved version from 1968 on. Improvements made to engine, ventiliation system, and Commander's night vision device added.
ZSU-23-4V1: Improved version after 1970 with improvements made to radar, improved disel engine, and fire-control to enable shoot-on-the-move.
ZSU-23-4M1: Modernized version from 1973 onwards. New autocannon installed (2A7M) with barrel life extended to 4500 rounds; pneumatic loading replaced with pyrotechnic loading, coolant tubes replaced with flexible piping. Older versions refurbished to M1 standard.
ZSU-23-4M3: IFF system installed, and added to older versions during depot-level overhaul.
ZSU-23-4M2: “Afghan Variant”: Radar (and radar operator) removed and night vision added for driver and gunner. Ammo capacity increased to 4,000 rounds.
Users:
Soviet Union: Standard SPAAG in most Motor-Rifle and Tank divisions. Issued four per regiment, alongside either SA-9 or SA-13 in Regimental air defense batteries. Also used by VDV Air Assault Divisions and by Naval Infantry Brigades. Independent Motor-Rifle Brigades used the “Afghan” version on convoy escort duty, especially in mountainous terrain, and also frequently used in urban warfare (First San Antonio, First Houston, Denver Siege, Dallas, Second Houston, Second San Antonio, among others). Still in service in many Post-Soviet States to date, with uprgrade programs in the Russian Republic, Ukraine, and the Far East Republic.
Cuba: Used as per Soviet practice in Armored and Motor-Rifle Divisions. Also used in Cuba proper for Air Base Defense. Surviving vehicles in Cuba destroyed or scrapped after Anti-Castro Uprising.
Czechoslovakia: Used in Tank and Motor-Rifle Divsions in North America and in 1989 East European Campaign.
East Germany: Used in all Tank and Motor-Rifle Divisions. Combat both in North America and in 1989.
Hungary: Used in both North America and in Hungarian Revolt, 1988-9 (on both sides).
Libya: Served in Armored and mechanized brigades in North America, 1986-89. Vehicles in Libya used to suppress anti-Qaddafi uprising before U.S/British nuclear attack on Libya after Qaddafi Regime's use of WMD on rebels, 2011. Survivors used by various factions.
Mexico: None used during the war, but vehicles left behind after the Armistice were taken over by the Mexican Army. Many expended during COIN operations or during Baja War in 2010. Some still in service.
Nicaragua: Used in Armored and Mechanized Divsions in North America and in Anti-Sandinista coup in 1995. Survivors later scrapped.
North Korea: Vehicle used in air defense batteries in both Armored and Mechanized Divisions in Northern Theater, 1986-9. Some combat during end of North Korean regime in 2010, with survivors being scrapped by ROK Army.
Poland: Used in Cat A and B Armored and Motor-Rifle Divisions. Service in both North America and 1989 campaign (also on both sides).
Captured Vehicles:
While the ZSU-23-4 was well known to American, British, and Canadian intelligence due to captured vehicles being passed to the West by the Israelis after the Yom Kippur War, the M2 and M3 versions were not known in detail prior to the outbreak of hostilities. Some captured versions were used by their new owners, especially the 83rd Mechanized Division, “The Rag-tag Circus”, while other specimens were sent to Aberdeen Proving Ground in Maryland or to the UK for evaluation and analysis. Some were reengined and used for OPFOR training, with some specimens in museums or private collections (the latter in the U.S and Canada).
