An effort was made to significantly increase the firepower by mounting the same 37 mm gun into a quad-mount on a T-34 medium tank chassis, but the vehicle never left the design stage as it was recommended by the Technical Council of the Ministry of Transport to use a newer tank chassis and the more powerful S-68 57 mm twin anti-aircraft autocannon, which was being developed at the time. The next step in Soviet tracked SPAAG technology would come with the ZSU-57-2, which was based on the T-54 medium tank chassis and was mass-produced in 1957–1960.
