During the Cold War, the Soviet Army was perhaps the deadliest fighting force the world had ever seen. Within its mechanized forces, the Soviets accomplished something that their American counterparts never could - the fielding of a self-propelled anti-aircraft gun (SPAAG) that could keep pace with its heavy armored formations. This volume examines the design, development and operational history of the Soviet Union's Cold War SPAAGs: the ZSU-37, ZSU-57-2, the infamous ZSU-23-4, and the 9K22 Tunguska (better known by its NATO reporting name: SA-19 'Grison'). These vehicles excelled in their air defense role, and many US Department of Defense publications were dedicated to examining how to defeat the ZSU and its radar tracking system. These formidable weapons equipped Russian forces in Afghanistan and were encountered again in Iraq during Operation Desert Storm and Iraqi Freedom, cementing their place in the landscape of modern warfare. This study explores the full history of the SPAAGs with revealing photographs, technical illustrations and detailed analysis.
