Historical Description and Application

Object 704 was an experimental Soviet self-propelled gun constructed at the end of World War II, in 1945–1946. Equipped with a modern, powerful ML-20SM 152.4mm gun, it was meant to serve as fire support for the armored forces of the Red Army. Despite its very modern silhouette and numerous technological innovations, Object 704 remained at the prototype stage and did not enter mass production. The test specimen has survived to this day and can be seen at the museum in Kubinka.
