One of the most talked about weapon systems on the world market is rightfully the air defense systems S-300 and S-400 produced by the VKO Almaz-Antey concern. In the near future, the Russian army will receive a new generation of these systems - the C-500, which will probably also become a bestseller. Sergey Druzin, Deputy General Director for Science and Technology Development, First Deputy General Designer of the Concern, told RIA Novosti observer Alexey Panshin about the history of development and creation of the national air defense system, about the participation of German designers in the work, about the reasons for the development of the S-400, and also about the advantages of the new Russian C-500 complex.
- Sergey Valentinovich, what was the driver for creating a national air defense system?
- The entire 20th century, in fact, witnessed the development of aviation. This was expressed in an increase in the bomb load, the speeds of the aircraft, and the number of aircraft was increased. If in the First World War it mainly performed the role of aerial reconnaissance, then already during the Second World War it became almost the main striking force. The significance and effectiveness of the aviation component became decisive, which required the adoption of adequate special measures to counter these increased threats.
The air defense systems that appeared during the First World War - anti-aircraft guns as an executive system of destruction, the so-called sound detectors, anti-aircraft searchlights for night time — all of them together ceased to meet the requirements that were imposed on them due to the increase in speeds and altitudes of the flight of aviation assets.
With the increase in the speed of the aircraft, the sound detectors became useless, because as the speed increased, the sound of the aircraft flew along with it, which did not allow to provide accurate aiming on the basis of this information. And by itself, shooting at high-speed targets, especially targets that go not to a position, but flying past, with a parameter, as the anti-aircraft gunners say, required the formation of pre-emptions - calculating the angles with which it was necessary to shoot in order to get to the pre-point. All this together led to the fact that the anti-aircraft artillery had largely exhausted itself, the question arose of creating new means of destruction, such as missiles. This gave impetus to the anti-aircraft missile.

- What was the role of German designers in the creation of a national air defense system?
- It must be admitted here that, as in many other areas, the German military specialists turned out to be largely pioneers - along with rocket weapons that were attacked in London, anti-aircraft missiles were also created. This was facilitated primarily by the fact that the density of bomb strikes and their striking power, which the Allies attacked the cities of Germany, demanded that radical measures be taken to counter these threats. German specialists have created several types of anti-aircraft missiles. Along with the FAU-2 attack missile projects, a number of anti-aircraft missiles were being developed, of which the most widespread Wasserfall (Waterfall) and Schmetterling (Butterfly) can be called, as well as the Typhoon rocket, resembling multiple launch rocket systems. On the way of the plane, these rockets were massively fired, warheads were separated from them by parachutes and hung on cables. This, of course, could not be effective armament — it was necessary to shoot them precisely so that the plane then touched the cable and a large number of these items were required.
During the war years, the Germans failed to bring these developments to their logical conclusion in order to adopt them. German specialists had unresolved problems that Soviet developers later faced. In particular, it is the accuracy of determining the coordinates that would allow the missiles to be effectively controlled in order to bring the missile to intercept the target.
After the war, certain work was done, and the specialists of NII-88, which was later transformed into the Energia rocket and space corporation, collected part of the equipment and technological reserves that were in our country. We managed to assemble a group of specialists from Germany. Some German engineers were engaged by our allies, then worked in the USA. For five years, attempts have been made to reanimate the backlog they have created.
- Who was the task of creating systems to protect the sky?
- In the Soviet Union, the Kapustin Yar test site was created, where work was carried out to study the backlog of German specialists in the field of air defense. However, we must admit with regret that the proper effect was not achieved. It did not happen then the system itself. But it came to the understanding that the anti-aircraft missile is not the main weapon, but the anti-aircraft complex.
In September 1947, Special Office 1 (SB-1) was established as the leading enterprise for the development of air-to-sea guided missile systems. The first director was Pavel Nikolaevich Kuksenko, his deputy was Sergey Beria. Three years later, in the SB-1, which was then located on the site of the present-day NPO Almaz, was established the Design Bureau No. 1 - KB-1 (now PJSC NPO Almaz), which was tasked with developing an anti-aircraft missile system to create an effective air defense of large cities and strategic objects.
The urgency of this problem was more than obvious - in the United States by that time a whole arsenal of atomic weapons had been accumulated and there were plans to bomb Moscow and other important administrative centers of the Soviet Union, which were adjusted every two to three years as capacity was increased. It is difficult to say which task was more important then - creating your own atomic bomb or air defense system. The solution of these problems restrained our former ally from the implementation of such plans.

Impenetrable sky. Russian cities will cover the new missile defense systemAccording to Izvestia, it is about creating a full-fledged non-strategic missile defense system. Its elements can be transferred from region to region and quickly deployed to rocket-prone areas.
- It turns out that the atomic bombing of Hiroshima and Nagasaki is an act of intimidation, terror in a sense?
- Of course. Then information about the bombing of Japanese cities in the United States willingly shared with Stalin in order to make it clearer to explain to him who the Soviet Union is dealing with. But even without this demonstrative atomic bombing of Hiroshima and Nagasaki, Soviet intelligence had information about the plans of the Americans, who confirmed that there were no moral restrictions for them. The United States was ready to strike a blow at the Soviet peaceful cities. Therefore, the need to create a reliable air protection system was more than obvious.
- As far as I understand, this is how the C-25 appeared.
- The decision to create an air defense system was connected to Alexander Andreevich Raspletin, who had a unique mindset and character. It was a keen mind seeker. He was able to rally a team of like-minded people who later created the C-25 system, which was ahead of time by decades. Americans at this time created a single-channel system Nike Ajax.
The C-25 system allowed to fire at the same time 20 targets. She was unique to her time. The coordinates were not measured by two different radars, but by one — both targets and missiles. Thus, the task of ensuring the accuracy of guidance was solved.
Then the daunting task of building an air defense system around the capital began to be solved. As a result, two concrete rings were formed around Moscow, which provided the necessary communications for the functioning of the C-25 system. On the outer ring 34 complexes were supplied, and on the inner ring - 22. Total, only 56 complexes instead of 300, which would have to be installed in such a quantity, were they single-channel. Thus, the task of minimizing funds for the creation of such systems was solved.
In late 1954 - early 1955, state testing of the system was completed. Nobody in the world has created anything like this. It should be noted that the radar equipment of the air defense missile system was the brainchild of Soviet designers, but German specialists were also involved in the creation of a missile control system. In particular, to the creation of autopilot.
- How was the C-75 concept born?
- The main drawback of the C-25 system was its stationarity. She could not be quickly relocated if necessary to cover other objects. Requires a mobile air defense system. In addition, during the development process, more advanced technical solutions were born, which then made it possible to create a mobile system. It was possible to place the entire antenna post of a missile guidance station on one chassis trailer - it consists of two antennas providing tracking and targets, and missiles in a narrower sector (plus or minus 10 degrees), command transmission antenna and corresponding transmitting devices.
It was a huge step forward for the antenna technology of the time. He allowed the creation of a mobile system that had approximately the same characteristics in range as the C-25 (30-35 km). By the sunset of the C-75 system, the target hit range had already reached 56 km. This made it possible to create a complex that could be moved to the right place, strengthened or created an air defense system, if it hadn’t been before.
- What prompted the creation of the C-200?
- The first reason is operational. In the north of our country at that time there was a serious communication problem. As is known, the maintenance of the air defense system requires regular supply of fuel. And the placement of complexes from each other is determined by the size of the affected area. To create a continuous zone in some cases was almost impossible.
The task was to increase the range of the complex in order to reduce the total number of installations. In addition, aviation cruise missiles appeared that were launched outside the affected area of the C-75 complex. But you have to shoot at the shooter, not the bullet, so the task arose to create a complex with a greater range. Originally created rocket provided a range of destruction of 160-180 km. The experience gained by this time in developing anti-aircraft missile systems showed that it was very difficult to ensure the required accuracy of the missile during remote control at distances over 50 kilometers. This required a radical increase in the warhead, as well as an improvement in the characteristics of the radar equipment, providing missile guidance.
It was a tremendous challenge to ensure the operation of a highly sensitive receiver while a powerful transmitter was working nearby. And this task was successfully solved - such a locator was created. As a result, the last modification of the system provided a range of rocket use up to 300 kilometers, and in fact began with 180.
- What are the changes in the "300"?
- The reason for the development of anti-aircraft missile systems is the development of air attack weapons, an increase in their density of action, as well as the appearance of cruise missiles. When instead of 15-20 targets in the sky there can be more than a hundred, this objectively requires an increase in fire performance.
Solving conflicting tasks — ensuring mobility and simultaneously firing a large number of targets — led to the need to build missile guidance radars on a different principle. It was necessary to use phased antenna arrays capable of providing instantaneous re-beam. Creating a phased array antenna and allowed to create multi-channel radar. Its principle is that with one beam you need to quickly measure the coordinates of several targets at once, quickly transferring it from one target to another.
The use of phased antenna arrays made it possible to create a multi-channel system. This is the fundamental difference of the S-300 complexes from all previous generations. The complex can be deployed to combat use from the march in five minutes. Another difference - the lack of cable connections between the shooting radar with launchers - all information is transmitted via a special radio link. The main designer of the complex was Boris Vasilyevich Bunkin. He was engaged in the testing and modernization of this complex.
- Why did the development of the next generation of air defense systems, the C-400, take so long, more than 10 years?
- The S-400 system was unlucky, like many other projects that were implemented by our defense industry in the 90s. Then the domestic defense industry suffered enormous damage, some of the personnel were lost, there was no normal funding. Work on the complex actually stopped. For the same reasons, rockets for this system were also developed for a long time. Nevertheless, the work was carried out, and by 2007 the first division of the C-400 was handed over to the Ministry of Defense and put on alert.
The principal difference of the S-400 system from the previous complexes is its noise immunity and fire performance. The number of simultaneously fired targets at the C-400 is much greater than that of the C-300. This is also ensured thanks to the appearance of a new intelligent rocket with a control system that allows it to use the widest range of application modes: both active homing and the use of information from external sources, other radars. The system also fires over-horizon targets - those that are not visible to the radar, but information about them is available in the system.

The head of Rostec called the US statements about the S-400 unfair competition
Each complex has its own technological base. The element base in the S-400 is different - miniaturization, the degree of integration of the elements made it possible, with smaller dimensions, to create a system with significantly higher characteristics. This applies to both the detection locator and the multi-station.
The command post of the system incorporates powerful radars that allow you to see the air situation at long distances. This allows him to set tasks and control their implementation by other complexes, including not only S-400, it can be air defense systems of other modifications, including S-300, it can be Pantsir, air defense complexes of ground forces. The S-400 system can be the basis for the grouping of air defense weapons. The system contains images of controlled funds in order not to set tasks for them that do not correspond to their technical characteristics. With-400 can with maximum efficiency to use all the tools that are given to her control.
- What will be the C-500, what can we tell about it now?
- This is a fundamentally new generation system. The basis of the location means of this system are locators built on the basis of active phased arrays in which there is no transmitting device - the signal is formed by the antenna itself. In its composition there are relatively small power amplifiers, which are phased in a special way. Instead of electrovacuum devices with voltages of 30-40 kV, devices with a voltage of not more than 27 V are used. This design simplifies the task significantly. This has a positive effect on reliability as well as on operational safety. Active phased arrays also allow to obtain more significant characteristics of the radiated power and the width of the spectrum of the signals used. Significantly higher and antenna performance.
Today, the technology of manufacturing AFAR (active phased antenna array - ed.) At the enterprises of the concern has been fully mastered. Locators have been created and are being tested as part of testing a new system.
The C-500 has a wide range of targets. The system can also be used to combat ballistic targets of all types. This required both an increase in the energy potential of the location means and the creation of new missiles that can work outside the atmosphere where aerodynamic control is impossible.
- Recently, it has been widely believed that the domestic defense industry lives exclusively on the groundwork that was created during the Soviet era, and is no longer capable of creating its own unique designs. Is it so?
- About ten years ago, unfortunately, that was exactly the case. In the times of the Soviet Union, the groundwork was really enormous, but today it is completely exhausted. Today we are creating new groundwork, on the basis of which modern tools are created. As an example, I can give the Vityaz air defense system, which was created already in the post-perestroika period. Technological and technical reserves of the former time are not used in it. One of the pioneers of this complex is Pavel Alekseevich Sozinov, General Designer of the Alma-Antey VKO concern. This is a 21st century system with colossal fire performance. These innovative systems include the C-500 system that is currently being created. Of course, the caveats have remained, but they are ideological, because mathematics and physics have not changed over the years.
