To replace the unfulfilled hopes of ZSU-57-2 armed with 57-mm Grabin guns with ring-loading, 17 in April 1957. guidance systems. This was our response to the adoption of the ZNU М426А211 in the USA.
Formally, Shilka and Yenisei were not competitors, since Shilka was designed to ensure
Air defense of motorized rifle regiments to engage targets at altitudes up to 1500 m, and "Yenisei" - for air defense tank regiments and divisions, and operated at altitudes up to 3000 m.
For the ZSU-37-2 in the OKB-43, the 37-mm Angara twin anti-aircraft gun was developed. It used two machines 500P, developed in OKB-16. "Angara" had a tape power system, a system of liquid cooling machines and tracking electro-hydraulic drives.
But in the future they planned to replace the purely electric drives. The drive drive systems were developed: the Central Research Institute 173 GKOT of Moscow (now Central Research Institute AG) - by power follow-up guidance drives; and the Kovrov branch of the TsNII-173 (now the Signal Research Institute) for the stabilization of the line of sight and the line of shot.
The “Angara” targeting was carried out with the help of the noise-free “Baikal” radar-instrumentation complex, created in the research institute-20 GKRE (Kuntsevo village). PKK "Baikal" worked in the centimeter wavelength range (about 3 cm).
Looking ahead, I will say - it turned out during tests that neither Tobol on Shilka nor Baikal on Yenisei could effectively search for an aerial target on their own. Therefore, even in the Council of Ministers resolution No. 426-211 of 17 of April 1957, it was planned to create and submit to the state tests in the second quarter of 1960 a mobile complex of the Ob radar to control the ZSU.
The Ob complex included the Neva command vehicle with the Irtysh target designation radar and the Baikal RPK located in the Yenisei ZSU. The Ob complex was to control the fire of six to eight ZSUs. By resolution of the Council of Ministers of 4 in July of 1959, the work on the Ob was stopped to speed up the development of the Krug anti-aircraft missile system.
The chassis for the Yenisei was designed in the Uralmash design bureau under the direction of G.S. Efimova on the chassis of an experienced SU-100P self-propelled unit. Its production was planned to expand on the Lipetsk Tractor Plant.
ZSU "Shilka" and "Yenisei" were simultaneously tested, albeit according to different test programs.
"Yenisei" had a zone of destruction in range and ceiling close to ZSU-57-2, and according to the commission on state tests "provided cover for tank forces in all types of combat, that is, air attack weapons for tank forces operate mainly at altitudes up to 3000 m ".
Normal shooting mode (tank) - continuous turn to 150 shots on the barrel, then break 30 seconds (air cooling) and repeat the cycle until the ammunition load is exhausted.
During the tests, it was found that one ZSU “Yenisei” outperforms a six-gun 57-mm C-60 cannon and a battery of four ZSU-57-2.
On tests ZSU "Yenisei" provided shooting in motion on the virgin soil with a speed of 20 — 25 km / h. When driving on a tank track (on the range) at a speed of 8 — 10 km / h, the accuracy of shooting was 25% lower than from a standstill. Accuracy of the Angar cannon in 2 — 2,5 is higher than the C-60 cannon.
During the state tests from the gun "Angara" made 6266 shots. Two delays and four breakdowns were noted, which amounted to 0,08% of delays and 0,06% of breakdowns of the number of shots fired, which is less than permissible according to tactical and technical requirements. During the tests, the CDS (equipment for protection against passive interference) failed. The chassis showed good maneuverability.
PKK "Baikal" functioned satisfactorily and showed the following results:
- limit of work on target speed - up to 660 m / s at altitudes greater than 300 m and 415 m / s at altitudes 100 — 300 m;
- the average detection range of the MiG-17 in the 30 sector without target designation - 18 km. The maximum range of tracking MiG-17 - 20 km;
- maximum vertical target tracking speed
- 40 degrees / s, horizontal - 60 degrees / s. Time of transfer to combat readiness from the preliminary
readiness - 10 — 15 with.
According to the test results of ZSU “Yenisei”, it was proposed to use it to protect the army’s Krug and Kub anti-aircraft missile systems, since the Yenisei effective firing zone blocked the dead zone of these air defense systems.
After the state trials of "Shilka" and "Yenisei", the state commission examined the comparative characteristics of both ZSU and issued an opinion on them.
I will give some excerpts from the conclusion of the commission:
- “Shilka” and “Yenisei” are equipped with a radar complex and provide shooting day and night in any weather.
- The weight of the Yenisei 28 tons, which is unacceptable for armament of motorized rifle units and airborne forces.
- When shooting at MiG-17 and IL-28 at a height of 200 and 500, the Shilka is more effective than the Enisei in 2 and 1,5 times, respectively.
"Yenisei" is designed for air defense tank regiments and tank divisions for the following reasons:
- Tank units and formations operate mainly in isolation from the main group of troops. "Yenisei" provides escort tanks at all stages of battle, on the march and on the field, provides effective fire at altitudes up to 3000 m and ranges to 4500 m. This installation virtually eliminates accurate tank bombing, which Shilka cannot provide.
- There are quite powerful high-explosive and armor-piercing shells, the Yenisei can conduct more effective self-defense shooting at ground targets while following in combat orders of the tank forces.
Unification of new ZSU with products in mass production:
According to "Shilka" - 23-mm machine gun and shots to it are in mass production. The tracked base SU-85 is manufactured at MMZ.
According to the “Yenisei” - the PKK is unified in modules with the “Krug” system, on a tracked base - from the SU-1 OOP, which 2 — 3 of the plant are preparing for production.
As in the above extracts from the test reports and the conclusion of the commission, and in other documents, there is no clear justification for the priority of “Shilka” in comparison with the “Yenisei”. Even their cost was comparable:
"Shilka" - 300 thousand rubles. and "Yenisei" - 400 thousand rubles.
The Commission recommended the adoption of both ZSU. But the decision of the Council of Ministers of 5 September 1962, the number 925-401 was adopted by one "Shilka", and 20 September of the same year followed the order of the CCFOT to stop work on the Yenisei. According to some reports, refuse to work on the "Enisey" N.S. Khrushchev was convinced by his son Sergei. An indirect proof of the delicacy of the situation was that two days after the work on the Yenisei was closed, an order was issued to the GKOT on the same remuneration of the organizations that worked on the Yenisei and Shilka.

According to the test results, ground targets were hit with armored 50 mm at a distance of up to 100 m and armored 40 mm at a distance of up to 500 m at an angle of projectile-60-90 angle. Effective fire has been recommended to queue up 3-5 shots. at a distance of no more than 600-700 m.

ZSU “Shilka” is more effective than “Yenisei” when firing at targets such as the MiG-17 at heights of 200 and 500 m, respectively, 2 and 1.5 times.
Shooting accuracy when driving on a tank test site at a speed of 8-10 km / h on 25% lower than when shooting from a place. The accuracy of shooting at 2-2.5 is higher than that of the C-68 cannon.
