With the start of the Great Patriotic War to the leadership of the Red Army faced the task of equipping the army to self anti-aircraft and guns. In pre-war years in Soviet different design bureau conducted the establishment of self-propelled artillery.
A number of works came to the small-scale production, but fully efficient installations have not been created. It is this state of affairs and led the People's Commissioner weapons Vannikova sign 1 July, 1941 ordered that the plant number 4 to develop and manufacture a 37-mm anti-aircraft gun on self-chassis, plant number 8 to develop and manufacture a 85-mm anti-aircraft gun on self-chassis And the plant number 92 in g.Gorkom (Nizhny Novgorod) to develop and manufacture a 57-mm anti-tank gun on self-chassis.
Order also provided for widespread use in samohodkah delivery industry and adopted by the Red Army vehicles, trucks, tractors. Projects samohodok were to be submitted for consideration no later than 15 July 1941. To achieve this goal, the factory number 92 was a special group of developers.
Project Manager has been appointed P.F. Muravyov. In a very short time samohodka was not just developed, but also manufactured in metal. In fact, a group of developers has proposed not one but two draft samohodki. At the end of July from the factory shops number 92 came two samohodki-VMS-30 and VMS-31.
VMS-30 was a mild anti-ACS open type. The base was an artillery tractor T-20 «Komsomolets, in the rear of the hull which was set rotating part of 57-mm cannon VMS-2 with a full shield. For greater stability in shooting machine equipped folding shoe. On the roof of the cab was installed mounting bracket on the gun - pohodnomu. The rest of the base engine T-20 remained unchanged. VMS -31 is the same gun VMS-2 but set in zabronirovannom triaxial truck GAZ-AAA.
In July and August have been testing both options, which revealed that the VMS-31 shooting with a greater accuracy than the VMS-30, because the installation of a truck turned out more stable than when shooting VMS-30. However, the VMS-30, as the installation of Track engine, has a higher prohodimostyu than its competitor wheel. It is a fact and has played a decisive role in adopting the Red Army samohodki VMS-30.
Order Vannikova, plant number 92 was to begin serial production of VMS-30 from 1 September 1941. However, the only manufacturer of T-20 was number 37 from Moscow factory, which since August has ceased production of trucks and switched to production of tanks, «Komsomoltsy» had to collect at military bases and installations except guns and even repair the machines, often delivered at Plant with the best. As a result, production of VMS-30 began with September 21 and lasted until 15 October 1941.
During this period, the plant produced 101 machine gun VMS-2 (including the pilot car) and an installation with 45-mm cannon. Further production facilities has been stopped due to lack of «Komsomoltsev». ACS VMS-30 began in troops in late September 1941. They were equipped with anti-tank batteries of 20 brigades western and south-western fronts. In the first battle, VMS-30 (this name samohodki almost was not known in the army). Usually in the documents it imenovali, as well as an instrument of VMS-2: «57-mm gun PTI»).
ACS is well behind them. This was primarily due to the fact that in 1941, 57-mm gun VMS-2 pierce armor of all types of armored vehicles Wehrmacht. A mobility installation allowed no problem changing firing positions. On the other hand, during the intensive use of the samohodki identified a number of weaknesses such as poor stability, congestion chassis, a small reserve, light ammunition.
By the summer of 1942, the troops remained virtually ACS VMS-30. Some vehicles were lost in battles, and some went down for technical reasons.
