ZSU-37 is a short-range Soviet tracked self-propelled anti-aircraft gun of the Second World War and the post-war period. The first prototypes were built in 1944, and serial production continued in 1945-1948. In its course, about 300 machines of this type were created. The car was equipped with two GAZ-202 carburetor engines with a capacity of 140-160 hp. It was armed with one 37-mm 61-K anti-aircraft gun and two 7.62-mm PPS submachine guns. The ZSU-37 was developed on the modernized chassis of the SU-76M self-propelled gun to provide short-range anti-aircraft cover for Soviet mechanized and armored units. A long period of research and development related to the selection of the appropriate chassis led to the fact that the ZSU-37 entered production only in March 1945 and was not used in combat operations during the battles in Europe. The gun performed well in the field, but it had a manual rotation of the turret and a mechanism for raising the weapon, which made the effectiveness of the new weapon questionable. Moreover, the very rapid development of aviation technology after 1945 and the large-scale introduction of jet aircraft completely overruled the suitability of the ZSU-37 for the tasks for which it was created. After all, in the 1950s, cars of this type were removed from the lineup.
