Stories about weapons. ZIS-30. Very bad luck
German mobility of mechanized and tank units at the beginning of the war immediately revealed the need for the Red Army in the means of confrontation. And not just anti-tank, but in mobile anti-tank and anti-aircraft self-propelled guns.
Tank units of the Wehrmacht turned out to be too operational, Soviet antitank batteries mounted on horse-drawn and car-thrusters looked too sluggish in terms of maneuver. And too vulnerable.
1 July 1941, the people's commissar of armaments, Boris Lvovich Vannikov, signed an order to read as follows:
1. Plant No.4 develop and manufacture an 37-mm anti-aircraft gun on a self-propelled chassis;
2. Plant No.8 develop and manufacture 85-mm anti-aircraft and anti-tank guns on self-propelled chassis;
3. Plant No.92 develop and manufacture an 57-mm anti-tank gun on a self-propelled chassis.
When designing equipment, focus on the industrial trucks used by artillery and all-terrain or tracked tractors. Anti-tank guns must also have an armored cockpit. Projects of self-propelled units must be submitted for review on July 15 of the year.
In fact, on the shoulders of Vannikov lay the problem of correcting the mistakes of Comrade Kulik, who understood little in artillery in general and command in particular, but the huge ambitions of Marshal Kulik allowed him to bury a lot.
Including ZIS-2, the excellent 57-mm anti-tank gun Grabin.
But here it is more appropriate to give the floor to Grabin himself.
We decided to install the guns on a tracked vehicle - to create a self-propelled gun. First of all, it concerned the anti-tank and divisional artillery: then it could appear where it was not expected.
At the end of 1940, the KB made a proposal to create self-propelled guns. The head of GAU, Marshal Kulik, met this proposal kindly. The idea of creating highly mobile and passable artillery did not leave us. We were looking for a tracked vehicle on which to install the ZIS-57 2-mm anti-tank gun and 76-mm F-22 USV divisional gun of the 1939 model year.
In the end, the idea of using the F-22 SPM had to be abandoned: this gun was too large in size. But the ZIS-2, mounted on a Komsomolets trailer and on a wheeled-tracked all-terrain vehicle, showed excellent results when tested by shooting and hauling: high accuracy of combat, rate of fire, stability, mobility and maneuverability on all roads and even off-road. ”
We are most interested in what happened at the factory number XXUMX. There, to implement the order of Vannikov, a separate group of designers was created under the leadership of Pyotr Fedorovich Muravyov.
As a result of the work, already at the end of July, two self-propelled guns came out of the factory gates: the ZIS-30 and ZIS-31.
The first was a swinging part of the 57-mm anti-tank gun ZiS-2, mounted on the Komsomolets artillery tractor T-20.
The second is the same ZIS-2 gun, but on a specially booked three-axle GAZ-AAA truck.
Comparative tests of two cars, conducted in July-August, showed that the ZIS-31 when firing is more stable and has greater accuracy than the ZIS-30.
However, due to the fact that the permeability of the ZIS-31 was significantly lower than the ZIS-30, preference was given to the latter.
According to the order of Vannikov, Plant No. 92 from 1 of September 1941 of the year was to begin mass production of the ZiS-30.
But the trouble has crept up at all not from where it could have been expected from. The only manufacturer of Komsomoltsev, the Moscow plant No. XXUMX, due to an incorrect planning policy, completely shut down the production of tractor units and switched to the production of tanks.
For the manufacture of ZIS-30, plant number 92 had to withdraw "Komsomoltsy" from military units and engage in repair of vehicles coming from the front. As a result of these delays, mass production of self-propelled guns began only with 21 September. In total, up to 15 in October, the 1941 manufactured the ZIS-101 machine with the 30-mm ZIS-57 gun (taking into account the first prototype machine) and one ZIS-2 with the 30-mm anti-tank gun.
On this, in fact, everything. The lack of a base for creating self-propelled guns completely spoiled the matter. The release of ZiS-30 has been discontinued.
The group of Peter Muravyev did not give up, realizing the importance of this self-propelled gun. And in early October, the project ZiS-41 appeared, in which the gun ZiS-2 was mounted on the chassis of the semi-tracked all-terrain vehicle ZiS-22, which was produced in Moscow.
Tested in November 1941, ZIS-41 showed good results. However, by this time the Moscow ZiS plant evacuated and, in principle, could not provide a sufficient number of ZiS-22 all-terrain vehicles. Therefore, at the end of November 1941, all work on ZIS-41 was stopped.
The ZiS-30 self-propelled guns began to enter the army at the end of September 1941. All of them went to the staffing of PTO batteries in tank brigades of the West and South-West gables (in all, they were equipped with about 20 tank brigades).
There is one thing that complicates any research in this area. It is almost impossible to document the ZIS-30 machine from the 57-mm ZIS-2 gun. The fact is that the factory index ZiS-30 was not known in the military, and therefore in military reports these vehicles passed as “57-mm VET guns” - just like the 57-mm ZiS-2 guns.
Extremely rarely, they go through the documents as "self-propelled 57-mm VET guns". Well, plus statements on fuels and lubricants allow you to accurately understand where ZiS-2 was used, and where ZiS-30. ZIS-2 fuel was not required.
In battles ZIS-30 showed themselves very well. So, already October 1 at the plenum of the artillery committee of the Main Artillery Directorate (GAU), chaired by E. Satel, was reported "about the successful combat use of ZiS-30 vehicles."
However, during longer operation, self-propelled guns revealed many shortcomings, primarily due to the fact that the original base was not adapted to become a self-propelled gun.
The GAU Artillery Committee received feedback from military units on 57-mm anti-tank guns ZiS-2 and ZiS-30. Regarding the latter, in particular, the following was said:
Let's just say: it could be worse. But, with all the shortcomings voiced, ZIS-30 fought and fought successfully. The 57-mm anti-tank gun ZIS-2 successfully hit all the tanks of that time. But alas, by the summer of 1942, there were practically no such vehicles left in the army. Some of them were lost in the battles, and some were out of order due to breakdowns. And there was simply no place to repair them, since the plant was now producing tanks.
What was the ZIS-30 ACS?
As already mentioned, the ZIS-30 was a swinging part of the 57-mm anti-tank gun ZIS-2 with a barrel length 73 caliber, installed openly on the Komsomolets T-20 semi-armored tractor.
Combat calculation of the installation consisted of five people.
The upper machine gun was mounted in the middle part of the machine body. Vertical pickup angles ranged from -5 to + 25 °, along the horizon - in the 30 ° sector. For targeting, a worm-type lifting sector mechanism and a screw-type rotary mechanism were used, which ensured the pickup speed 4 degrees / s.
When shooting, a standard PS-2 or OP2-55 sight was used. Sight PP1-2 was used both for direct fire shooting, and when firing from closed firing positions. It consisted of a panorama and sighting part, interconnected by screws. At night, the device “Ray-1” was used to illuminate the sight scales.
A vertical wedge valve with a semi-automatic copier type allowed to achieve a rate of fire to 25 rds / min., The target rate of fire was 15 rds / min.
Shooting was conducted only from a place. The stability of the self-propelled installation when firing was provided with the help of folding coulters located in the rear part of the machine body.
Fastening of the gun in a marching way on the march was provided by means of a bracket mounted on the roof of the cab of the car, and a special stopper located in the rear of the hull.
For self-defense of the self-propelled unit, a regular DT 7,62-mm machine gun was used, which was installed in the ball joint on the right in the front cabin leaf. The machine gun was easily removed and used as a handheld.
The ammunition carried on the ZIS-30 included 20 shots to the cannon and 756 cartridges for the DT machine gun (12 disks).
The ammunition of the installation included shots with subcaliber (UBR-27Sh, UBR-271H), fragmentation (UO-271U or UO-271UZH) and armor-piercing tracer stupid-headed and sharp-headed (UBR-271, UBR-271K-XB-XN-X-UM-271, UBR-XNUMXK).
The range of the direct shot of an armor-piercing projectile with a target height of 2 m was 1100 m. The firing range of the fragmentation grenade UO-271U was 8400 m.
The power plant, transmission and running gear of the self-propelled unit ZIS-30 remained unchanged compared with the semi-armored tractor T-20, which we have already told here:
