57mm ZSU-57-2

The ZSU-57-2 is a Soviet self-propelled anti-aircraft gun (SPAAG) armed with twin 57mm autocannons, mounted on a modified T-54 tank chassis. It was designed to provide air defense against low-flying aircraft for motorized and tank regiments.

Developed in the post-WWII era to counter the threat of high-speed jet aircraft, the ZSU-57-2 officially entered Soviet service in 1955. It saw extensive combat deployment globally, most notably during the Vietnam War with North Vietnamese forces and in various Middle Eastern conflicts, including the Six-Day and Yom Kippur Wars. Despite its heavy firepower, the vehicle's lack of radar tracking and manual optical sights rendered it obsolete against modern supersonic jets, leading to its replacement by the radar-guided ZSU-23-4 Shilka. Today, while retired from front-line Russian service, it remains in active reserve or secondary roles in several nations, often repurposed for direct-fire ground support.
