ZSU-37-2 "Yenisei". Not a "Shilka" single

The absence of ZSU in the air defense of the troops, one of the saddest moments in stories Red Army. After the end of the Second World War in the USSR, the correction of errors was taken seriously. The most famous ZSU in the world was the Soviet ZSU-23-4 “Shilka”, but few people know that she had a stronger, sibling ZSU-37-2 “Yenisei”.

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.

ZSU-37-2 "Yenisei". Not a "Shilka" single

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.

        Right - wrong / accepted - not accepted.
        All this reasoning is just talk!
        There is only one reason - banal, but against the backdrop of the then global development of new types of weapons, this pepelats simply didn’t have enough money - but it’s a pity ...

    That's what I said about this artillery assault rifle, offering it for a new weighted (due to additional protection) BMP.
    I think that this is the most suitable caliber. Unfortunately I know little about this machine, what shells exist for it, what is the potential for modernization.
    But the caliber is the most for urban combat, infantry combat. 30mm is small, the HE is rather weak, and here would be more powerful. For this caliber, a whole line of shells could be fired.

    From the point of view of history, it seems that the decision was right. Missiles proved to be more effective at heights - and as a result of medium-caliber air defense systems, they were no longer being developed, they aren’t in service and now - 30mm is probably enough ... Of course, the Swedes tried to push their Bofors into everything that was moving, but this is most likely due to ordinary commerce .
    And about the S-60 batteries, and their self-propelled options, - everyone who served in the air defense told me that their effectiveness is just miserable, and we don’t need to be afraid of such weapons at 23x - they can get in - but by accident. One guy from Israel said that they weren’t very afraid of them - but one of them covered RTR where Dad fought, and he thought that they were cool covered .... So - not like that - I personally checked the effectiveness of 57mm. Although the Vietnamese seemed to have shot down something.
    It is also interesting that "air attack weapons against tank troops mainly operate at altitudes up to 3000 m" - how interesting was it possible to operate on tanks from 2 km and above in the 60s? Is that an atomic bomb ...
    So, it’s right that they chose Shilka.

      Very accurately noted by the respected Su-9, they chose not the "best" (since it is relatively difficult to make a choice based on the simulated situation), but the optimal one. And such a difficult choice is the reverse side of the competitive design. Nowadays, it is customary to scold N.S. Khrushchev, however, it was he who made the warriors make this very choice, which saved many people's money, directing them to other sectors of the national economy. Who knows if under Brezhnev / Andropov in the government there was a figure capable of being a "counterweight" to Ustinov there would be no marasmus with three main tanks in service, did not rebuild (in fact) whole series of Schuk, etc., etc. Regarding the heights, I want to note that both in the 60s and in the 80s the tank as a target for the IBA ( for example) existed only in the form of a "column on the march" in all other variants as an "area target" (a bombing maneuver with a target search depending on the weather up to 3000m, and "from sin on further" 3500-4000m, the output is not lower than 1500m ), and although with the advent of the MiG-27, the possibility of defeat a single IMMOVABLE tank appeared, the tactics remained the same. For Strashila and mirag2, the gun caliber should be considered as part of the equation of work (after all, the gun and the projectile are interacting heat engines) throughout the twentieth century, designers tried to deceive this equation and still came to optimal values ​​(note all calibers in the world are close in class 152 -155mm) So, according to the tables, after 30mm (and it is optimal from a thermal point of view) 57mm goes (and in thermal calculations, linear measures are always in inches) in calibers from 30 to 57mm guns can be created, but subject to the balance of characteristics, this will be expensive, small-scale samples. Systems with a caliber of 27mm or 35mm allow you to achieve some gain in ballistics in the case of using a detachable projectile pallet, but its damaging effect will be at the level of the actual caliber of the projectile itself, i.e., the same up to 24,2mm and 30mm. As an example of all that has been said (chaotic for which I apologize) M4-37mm (USA) and Mk108-30mm (Germany) air cannons had approximately the same damaging effect of the projectile, despite the fact that the 108th ballistics was "more" the rate of fire is much higher and the mass and recoil is much lower.

        Mnogabukf ... laughing

        But for some reason I believe the stories of my father-in-law - State Prize winner at Tunguska.
        He told how when they created Tunguska, he traveled in parts - he controlled the repairmen. They asked him to talk about the new system at the artillery academy in Poland (or at the headquarters of the Special Forces - I don’t remember exactly). Well told, and the Poles anti-aircraft gunners ask, including why 30mm.
        Well, I say, I'm starting to prove that this is an optimum such as the weight of the projectile, the action at the target, etc., but I myself know that the optimum is -35mm. Just by then all the plants were already set up for 30mm production laughing
        So ... His opinion was that the optimal caliber was 35mm (well, in our 37mm).

    In order to increase the Shilki's firing range, the North Koreans installed 2 30-mm artillery guns in its turret, presumably AK-230 naval guns, with an effective firing range of about 5 km. The hull is generally similar to that of the ZSU-23-4, however, it is larger. The same applies to the tower, it is more massive than that of Shilka. It is clear why: the main armament is two 30-mm cannons with a rate of fire of 800 rounds per minute per barrel. The vehicle can hit targets at a range of 3000-3500 m.

    An interesting ZSU was developed in the 50s in Czechoslovakia:
    ZSU M53 / 59 "Prague" was developed in accordance with the requirements of the Czechoslovak army in the late 50s. The armored hull of this ZSU is installed on a modified chassis of the Czechoslovakian V-3S Praha truck. Engine - a six-cylinder water-cooled diesel Tatra T 912-2 with a capacity of 110 hp. from. was in front of the ZSU. Its hood, like the cockpit, was made of aluminum armor plates with the addition of titanium, the thickness of which in the frontal part reached 10 mm. The crew of three was located in the cockpit, in the frontal armor plate of which there are two windows covered with armored shields.
    The armament of the ZSU is located at the rear, on a horizontal platform, and consists of an openly mounted M53 rotary mount with two 30-mm automatic weapons, the firing range of which is 3000 m. The ammunition includes several types of shells, the ammunition carrying capacity of 600-800 shells. Above the trunks of the anti-aircraft installation is a vertical horn-type store with 50 shells. The firing in azimuth is circular, and in the vertical plane, from -10 degrees. up to +85 degrees The transfer time from marching to combat position is one minute. It is possible to quickly dismantle an anti-aircraft installation using two retractable ramps mounted on a platform. It was assumed that the ZSU would be able to destroy air targets flying at speeds up to 350 m / s and at altitudes up to 3500 m, and it could hit airborne landing and ground targets at ranges up to 2000 m.
    Among the shortcomings of this ZSU, it is worth noting the absence of a detection system, and the fact that the aiming was only visual.
    It entered service with the Yugoslav People's Army in 1969, at the same time its production began by forces of the Yugoslav industry. By the early 1980s, JNA received 789 ZSU. "Prague" were attached to the mixed artillery and missile air defense divisions of the ground brigades of the Yugoslav army. Each such division, among other weapons, received 12 M53 / 59. "Prague" periodically underwent modernization, there were several projects that involved a significant strengthening of these ZSU by installing new engines, new sights, etc. But the collapse of Yugoslavia forced the military to abandon such plans.
    In wars in the vastness of the former Yugoslavia, "Prague" were used in Croatia, Bosnia and Herzegovina and Kosovo. In the first two wars, they mainly supported the actions of the infantry units. In defense, they acted from makeshift shelters, sometimes the ZSU was covered with steel bars in order to protect it from anti-tank missiles. 12,7 mm machine guns were added to many ZSUs. The peculiarity of the "Prague" was the sound of shots, which produced a strong psychological effect.
    The M53 / 59 fell short of its main purpose only once - on June 24, 1992, the Croatian MiG-21 was shot down in Posavin. The rare occurrence of air targets had an extremely negative effect on the training of crews who, by the time of the NATO bombing of the Republika Srpska in 1995, simply had little combat skills in aviation.
    In 1999, the Yugoslav Prags shot down 3 unmanned aerial vehicles and 12 NATO cruise missiles. But by the time of the aggression against the FRY, this ZSU was already morally obsolete.

    Here is a real true Iranian "wunderwaffe" with eight barrels ...

    and this is about six trunks

    but the North Korean ZSU based on the Soviet 57-mm twin S-68 anti-aircraft gun used in the ZSU-57-2 anti-aircraft self-propelled gun, as can be seen from the photograph without a radar

    On the basis of the captured ZU-23 and the Samil-100 truck, the Zumlak ZU was created in South Africa

    In Egypt, the Sinai-23 ZSU was created, including the ZU-23-2, 4 Ayn as-Saqr missiles (Egyptian copy of the Strela-2M MANPADS) and the Dassault 6SD-20S radar based on the M113 armored personnel carrier),

    Yugoslav ZSU BOV-3. During development, it was decided to equip it with a licensed version of the Hispanic-Suiz HS804 gun - the M55 A4B1 gun. Rate of fire - 750 rounds per minute. The effective range for ground targets is 2000 meters, and for air targets 1500 meters. A significant drawback of the ZSU was the placement of stores for 60 shells each on top of the guns. Recharge from the inside is not possible. The rest of the ammunition from 22 stores was in the tower. It is equipped with a J-171 optical sight. ZOV BOV-3 remains in service with the armies of Serbia (85 units) and Bosnia and Herzegovina (29 units). In Serbia, these ZSU are in reserve air defense.

    Judging by the followers, the caliber and ideology of the ZSU-sparks was picked up precisely by foreign developers.

      No. On the contrary. See M19 born in 1944

    But I, on the contrary, think that the Su-9 is wrong and, ideally, Yenisei and Shilka (the first for tank and, possibly, MP divisions.), Shilka for the Airborne Forces and Marines should be adopted. Yenisei only. Because of its weight of under 30 tons, it was not suitable for naval and airborne landing, and for them they would still have to make a shaitan arba based on MTLB or a truck in general. And only the third option is what was accepted, t. e. only Shilka.
    It’s another matter if the caliber on Shilka was changed to 30mm (in fact, as promised), and so the time of Shilka ended already in the mid-70s, i.e. with the advent of anti-tank helicopters with missiles with a range of 3.5-4km.
    There are still a few nuances. The 37mm projectile has the opportunity to improve efficiency, in particular due to the radio fuse, the 23mm projectile means, no. The Yenisei had its own Alien defendant initially, it was put on Shilka some 20 years later. The Yenisei was from the very beginning, the TV-optical sighting device doesn’t have Shilka. The vitality of the Yenisei should be higher — the armor is slightly better + the front location of the engine (however, as it would be in reality, it’s impossible to say). Well, what kind of armor does Shilka have at a distance of 2 km and above, it is clear that no

    Yes, the 3cm radar station on the Yenisei should have been more powerful and less dependent on weather conditions.The 1.5cm range for Shilka was chosen only because it was used less and an interference station was not created for it. Meanwhile, in the Middle East, the Arab Pvoshniki tried not to turn on the radar at all and fired with the help of an understudy with near-zero efficiency.
    Then it’s better with TOV, which was on the Yenisei

    In principle, these devices can be called the forerunner of the Terminator! Just then nobody thought about it.
