Anti-ship ballistic missile DF-21D (China)

65
The standard means of attack of surface ships are currently anti-ship cruise missiles of various types. Like weapon It has proved itself well both in the course of trials and exercises, and in conditions of real conflicts. Nevertheless, from time to time attempts are being made to bring other weapons of similar purpose to practical use. For some time around the world, the Chinese project of the DF-21D ballistic anti-ship missile is widely known. It is noteworthy that there is very little reliable data on this development, but it still attracts the attention of specialists and has a certain influence on the international situation.


It should be noted that the Chinese DF-21D, contrary to some assertions, is not the world's first ballistic RCC - similar products were developed and tested in the Soviet Union in the sixties and seventies of the last century. Nevertheless, according to a number of sources, the Chinese rocket managed to become the first weapon of its class, which managed to reach mass production and adoption. This fact is a cause for concern of foreign military analysts. In addition, the DF-21D rocket is considered potentially dangerous by many representatives of the military departments of foreign countries.

Unfortunately, China does not seek to disclose the details of its bold projects, which is why the overall picture has to be made up of fragmentary information that is not always complete, and sometimes can even contradict each other. Nevertheless, the available data allow us to approximately provide history project DF-21D and make some assumptions about the technical features of the new rocket.

According to known data, the anti-ship ballistic missile DF-21D is a further development of the products of the Dongfeng-21 family. Approximately at the beginning of the seventies, the Chinese command proposed to refine the existing project of a medium-range missile for the Juylan-1 (JL-1) submarines in order to create similar land-based weapons. The result was the emergence of the Dongfeng 21 project (East Wind 21). In the mid-eighties, Chinese experts began testing new missiles.

It is known that in the framework of the DF-21 program, by the middle of the two thousandth, at least three missiles with different characteristics were developed. DF-21, DF-21A and DF-21C products are intended for attacking enemy fixed objects at ranges up to 2500-2700 km. Missiles are transported and launched using self-propelled launchers based on high-capacity wheeled chassis. There is information about the deployment of such weapons on various missile bases in China.

In the late nineties or early 2000s, work began on a new family project, known as DF-21D. A characteristic feature of this development, which distinguishes it from its predecessors, is an unusual purpose. The new missile was proposed for attacking mobile surface targets, such as aircraft carriers and other large warships. Information about the possible beginning of the test of ballistic RCC refers to 2005-2006 years. At the same time, as often happens with new Chinese projects, the official Beijing did not comment in any way on the data of foreign sources about the beginning of such works.

To date, the existence of a promising anti-ship missile DF-21D is no longer a secret and is confirmed by official Chinese sources. In addition, according to American intelligence officers, already in 2010, the Chinese armed forces began to develop such systems. Quite expectedly, such information led to the beginning of a mass of disputes at different levels. They discussed both the plausibility of information on the creation of a ballistic PKR, and the prospects of such a project from the point of view of international politics and the strategic situation on the seas.

Let's try to collect all the available information about the DF-21D rocket and determine its main features. Until a certain time, a new type of rocket was not shown publicly. Because of this, most of the estimates and assumptions about it were based on the thesis of the possible similarity of the DF-21C and DF-21D missiles. In early September, 2015, a parade took place dedicated to the 70 anniversary of the end of the Second World War. During this event, the Chinese army for the first time showed a new ballistic anti-ship missile. As it turned out, the two systems are really similar in appearance, but all their differences, for obvious reasons, are hidden from observers.

The main element of the DF-21D missile system is a special five-axle chassis on which the transport and launch container of the rocket is transported. The use of a self-propelled chassis allows you to transfer missiles to the desired area and launch from the minimum distance from the target. After arriving at the position, the container of the rocket is proposed to be raised to a vertical position, while simultaneously dropping its head cover. The appearance of the container suggests that the launch is carried out according to the method of so-called. cold start, in which the rocket is pushed out of the TPC using a powder charge, creating the necessary pressure.

It is known that the Dongfeng-21 family of rockets are built according to a two-stage scheme and get solid propellant engines. According to some reports, the new product DF-21D was no exception to this pattern. As in the case of the predecessors, the anti-ship missile must be dispersed in the active section with the help of two engines, working alternately. After the completion of the second stage engine, the head section must be separated, equipped with its own guidance systems and carrying warhead.

According to various estimates, the DF-21D rocket has a length of the order of 10-12 m and a diameter of about 1,5 m. The launch weight is estimated at 14-16 t. In foreign sources there are approximate data on the range of a similar product. It is alleged that it is able to attack surface targets at a distance from 100 to 1450 km. This is noticeably less than that of other missiles of the family, some of which are capable of hitting objects at a distance of at least 2500 km. Apparently, a shorter flight range indicates the use of a more complex warhead with relatively large and heavy guidance tools, which affected the available volumes to accommodate the engine fuel.

There is still no reliable information about target designation systems, target search and targeting systems used by the DF-21D rocket. Various versions are offered, some of which are confirmed in the form of certain facts, but official Beijing is still not in a hurry to confirm or deny the speculations of foreign experts. As a result, the principles of missile guidance remain unknown and continue to be the subject of numerous disputes.

In the context of the Chinese ballistic RCC project, it is necessary to once again recall similar Soviet developments. It is known that the P-27K rocket was supposed to carry a passive radar homing head. When moving along a ballistic trajectory after the completion of the active part of the flight, the rocket automatics had to receive the signals of the electronic systems of the target ship and calculate the trajectory required for its defeat. Then, with the help of its own engine, the second stage of the rocket had to correct the course, reach the desired trajectory and literally fall to the lead point, hitting the target.

A later Soviet project of a similar weapon called the P-33 implied the use of a passive-active radar seeker capable of receiving signals from a target or searching for it on its own. In this case, the course correction was to occur not only in the transatmospheric part of the trajectory, but also on its downward part, after entering the atmosphere. It should be noted that in the course of the research, serious drawbacks of this method of guidance were identified. It was required to create a durable and heat-resistant radiotransparent head fairing of the rocket. In addition, when a product was moving at high speed, a plasma sheath should be formed around it, making it difficult for the GOS to work. Until the termination of work on the project P-33, these problems have not been resolved.

What kind of guidance system is used on the DF-21D is unknown. It is noteworthy that the appearance of reliable information on this score will allow to draw certain conclusions about the development of Chinese science and technology. If it turns out that the DF-21D is equipped with a conventional inertial guidance system, it will show the lag in Chinese industry. The implementation of passive or active guidance and course correction before entering the atmosphere will indicate a repetition of the success of the P-27K project. Equipping the rocket with an active homing system that works on the downward part of the trajectory, in turn, will demonstrate the successful solution of a number of the most important design and technological problems that scientists from all leading countries have been working on for quite some time.

Thus, the existing secrecy atmosphere surrounding the DF-21D rocket hides not only the main features of the product, but also some factors that directly affect the development of Chinese rocket technology. The appearance of such data in the public domain can create a real sensation, either by reassuring foreign experts, or, conversely, by scaring them.

The most important elements of anti-ship missile systems are targeting systems. Without accurate data on the location of the target, the DF-21D rocket or other systems of a similar purpose, by definition, cannot perform an attack with at least some acceptable effectiveness. There are some assumptions and versions regarding the construction by China of systems for detecting potential enemy enemy ship groups. According to reports, over the past years, the Chinese military has been engaged in the deployment of a satellite reconnaissance system, as well as building some other ground facilities.

Since the middle of the last decade, China has put several dozen Yaogan spacecraft into orbit. According to foreign experts, these satellites carry optical and radar reconnaissance systems. With their help, it is supposed to monitor different regions of the Earth, including the western part of the Pacific Ocean adjacent to the shores of Southeast Asia. The mission of the satellites responsible for this area is to detect ship groups of foreign countries and determine their coordinates, followed by issuing information to consumers, including anti-ship missile systems.

According to some reports, at present, China is also working on a new project aimed at developing systems for detecting enemy ships. Satellite reconnaissance is proposed to supplement the over-the-horizon radar stations. Foreign media claim that such projects have already reached the stages of testing in field conditions.

It should be noted that the characteristics of the DF-21D rocket allow to some extent to simplify the targeting system. Due to the firing range of no more than 1500 km, there is no need to cover the entire Pacific Ocean or other areas of the planet. In fact, it is necessary to monitor objects at a distance of no more than 2000-2500 km from the existing positions of the missile system. This will allow time to identify the threat and take it to escort until the attack. However, this does not negate the need to deploy a powerful grouping of various tools that monitor other regions.

Not earlier than the end of the 21s, the DF-XNUMXD ballistic anti-ship missile was adopted by the Chinese army. This weapon, it is claimed, allows you to effectively protect the coast from possible attacks from the sea and to keep a potential enemy at a great distance from the coast. In this case, the shock potential can be significantly reduced. fleet enemy with corresponding consequences for the conflict.

In the context of a hypothetical conflict between China and the United States, this means that until the suppression and destruction of the DF-21D complexes, American aircraft carrier strike groups could not risk less than 1400-1500 km approaching the Chinese coast, which is why aviation will lose the ability to work effectively on the coast and remote land areas. The destruction of ballistic anti-ship missiles as part of mobile systems, which allows to begin full-fledged combat work in the coastal zone, is a rather difficult task for the fleet of a potential enemy.

A few years ago it became known that the Chinese industry is working on the development of the DF-21 project. In the foreseeable future, rocket troops will have to receive a medium-range DF-26 rocket, the firing range of which, according to various sources, will reach 3-5 thousand km. Apparently, this will be a ground-to-ground ballistic missile, but some sources mention the possibility of creating an anti-ship version of the product. There is no confirmation of this version yet.

In September last year, the first demonstration of the self-propelled launcher of the DF-26 complex took place at a parade in Beijing. Due to the increased characteristics of the rocket and its container are different from other systems of the family "Dongfeng-21" large size. Also used a new six-axle chassis of greater capacity.

The DF-21D ballistic missile is of great interest not only from the point of view of technology and influence on the strategic environment. It is also interesting that this product, about which far from everything is known, even in the conditions of a lack of information could become a subject of discussion not only for the general public, but also for specialists, including in military departments of different countries. Not all new models of weapons manage to produce such an effect, as well as have a noticeable impact not only on the defense capability of their country, but also on the plans of other states.

    And at what speed does the plasma begin to form that interfere with the operation of an active seeker? If it is not too low (in comparison with the Raman scattering), then can it make sense to slow down the MS in the atmosphere before this plasma begins to form?
    Specialists, what do you say?

      In plasma, the most high-warhead is almost invisible by the locator and it is difficult to direct a missile defense at it. wink Therefore, they try to have the highest possible speed in the last section, which makes interception difficult because of time constraints and the missile’s overload ability.

        Plasma does not interfere with the work of the GOS

        The Chinese have never hidden the fact that their Dongfeng-21D is a further development of the Pershing-2 INF idea (which also had a maneuvering warhead). Only instead of the exact coordinates of the bunker - a moving aircraft carrier. Fortunately, over the past 30 years, radars and computing systems have made great strides.


        The main secret of the "Pershing-2" was a maneuvering warhead equipped with the Radar Digital Area Guidance (RADAG) homing system.

        Touching the stars at an altitude of 300 km, the warhead was rapidly returning to the Earth’s atmosphere. In the depths of the body, reliably protected from heat, cold and overloads, methodically ticked off the seconds on-board computer ... 428, 429, 430 - the Karman line was passed. It's time! Guided by the data of the gyroscopes of the INS, the combat unit "Pershing-2" was deployed in space perpendicular to the fall trajectory. Brakes! Brakes! Plasma streams shreds off the slippery surface of the hull and are carried away into the purple mist of the stratosphere. At first, weak and discharged, the atmosphere is already confidently whistling overboard, swaying in their streams the brave man who dared to defy the air of the ocean.

        At an altitude of about 15 km, the Pershing-2 extinguished speed to 2-3 speeds of sound, the INS once again oriented the warhead properly - and the most interesting began. Radar of the RADAG system came to life under the ablative plastic fairing - the warhead received an annular image of the underlying relief due to scanning around the vertical axis with an angular velocity of 2 rev / sec. Four reference images of the target area for different heights, recorded in the form of a matrix, each cell of which corresponded to the brightness of a given area in the selected radio wave range, were stored in the onboard computer's memory. Comparing the data obtained with the radar maps stored in the memory, the warhead determined its current position and the error of the ANN. The correction of the combat unit was carried out using aerodynamic surfaces with hydraulic drive.


        So the plasma has nothing to do with it. RLGSN turns on after reducing the speed to 2-3 speeds of sound.

        In fact, the DF-21D is another Chinese profanation. The maneuvering combat unit of the BR itself is extremely vulnerable to naval air defense systems. An object at a speed of Mach 2-3, at an altitude of 10-15 thousand meters - an ideal target for Aegis

              Oleg, as a rule, in ballistic anti-ship missiles, additional target reconnaissance is used after preliminary guidance using radars with a synthesized aperture at warheads. This is before passing the plasma cloud. After that, they can use another radar station or opto-IR or opto-photon, working on contrast and correlation according to reference images.

        Like any metal containing free electrons, ionized gas (plasma) has excellent electrical conductivity.

        Now we turn to the basics of radar. Here, everything determines the principle of changing the direction of movement of radio waves when passing through a non-uniform medium. AND the higher the electrical conductivity of the reflecting medium, the stronger the reflection of radio waves from the interface between two media.

        Confirmation of high reflectivity of plasma serves reflection of radio waves from the Earth’s ionosphere.
        \
        1919 year. J. Hattinger obtains a patent for a plasma antenna. A device for emitting and receiving radio waves, which uses ionized gas instead of metallic conductors. Hattinger's invention was not immediately used. Only today, with the advent of plasma solid-state antennas, the possibility of creating high-speed data exchange networks (WiGig) has appeared.


        There is also the effect of a temporary loss of radio communication during the descent of spacecraft from orbit. But the connection does not disappear because of the invisibility of the spacecraft. It disappears due to the combustion of antennas on the body of the descent vehicle at the entrance to the dense layers of the atmosphere.The descending capsule is visible from the Earth, but it is impossible to contact the astronauts sitting inside. If necessary, this problem can be solved in the original way. Engineers suggest using a plasma cloud itself as an antenna ... enveloping the descent vehicle.

      If the body is moving at supersonic speed, then deceleration occurs first in the shock wave arising in front of the body, then directly at its very surface, where the deceleration is caused by viscous forces that force gas molecules to "stick" to the surface, forming the so-called boundary layer. When the flow decelerates, its kinetic energy decreases, and, accordingly, the internal energy of the gas and its temperature increase. The energy of the chaotic movement of molecules increases, and the temperature increases, electrons are "ripped off" from molecules - ionization + heating of course (heat is transferred both by thermal conduction and using radiation)

I would especially like to draw your attention to the word "ballistic". Those projects that you wrote about can hardly be attributed to this category.
        About the Iskander. Thing, no dispute, interesting. Especially in the configuration with a tactical nuclear charge, an ordinary warhead of increased power and a cluster warhead, and this is what I mean, missiles flying in ballistics. And in bad weather, and with a strong, gusty wind, which often happens in different regions of the globe, with the accuracy of hitting, even with modern technology, it is not so simple. But the Iskander also has cruise missiles. And here again we run into Glonass and GPS and special forces, which can illuminate the target. And in systems like the Russian A-50.
        And to "Status-6". There are, they say, in the USA "Area 51", in Tibet and in Antarctica, secret bases, which were created by Hitler. And most importantly, there are people on all continents who have children and grandchildren. And these people want to do everything for their children and grandchildren to live.

      The operation scheme of the radar seeker detachable head of the anti-ship ballistic missile:
      - on approaching the boundary of the Earth’s atmosphere at an altitude of 100 km and a distance of 150 km from the target, the GOS scans the area of ​​the ship’s constellation determined according to the data of the over-the-horizon radar;
      - after entering the atmosphere, the warhead begins to maneuver intensively with the help of controlled aerodynamic surfaces in order to avoid interception of the ship’s anti-missile system;
      - at the first stage of descent into the atmosphere, the warhead flies into the blind in a plasma cloud screening the signals of the radar seeker;
      - after dropping the speed to 3 km / s, the plasma disappears, the GOS determines the coordinates of the target and the warhead hits it with a CVT of the order of 10 meters.

      In reality, when attacking a naval grouping, more than one ballistic missile and an echeloned attack scheme will be used - the first missile in order, when approaching the atmospheric boundary, distributes targets between the other missiles (similar to the Granit / Basalt anti-ship missiles) and detonates its nuclear warhead after descent to an altitude of 30-40 km with the generation of a super-powerful EMP, which knocks out all the radar stations of the ship formation and carrier-based aircraft. In this case, the second-echelon missiles will be protected from the impulse by a plasma cloud.

At 80km the atmosphere is also rarefied, but I think you can put the RCGS into such a bandura, which the aircraft carrier can see from such a distance, although it can be seen from 300km when viewed from above, but let it be 80km. Immediately after detection, due to the additional engine, the GOS, without stopping to hold the target, moves to a trajectory parallel to the surface, and without entering the dense layers of the atmosphere, it actually moves in space. And 600-700 kg of trotyl flies down with an additional accelerator, aimed at the GOS radio receiver and gas-dynamic rudders.
    There is no point in knocking down the seeker while the zur reaches it, the TNT will be already on the deck, the charge itself can be knocked down if it is closed with 2-3 cm of armor only by a direct hit. And knowing the end point, you can make the charge maneuvering. Moreover, with the mass launch of such missiles, it is possible to implement the principle of a flock, with a comparison of information from all GOS, in order to filter interference, and control of all ammunition from one homing head.

        BB "lives" for a maximum of 30 minutes. The radar of them works on the strength of 50% of the time.
        The energy will be provided either by a high-capacity battery of the "burning type" (conventional penetrating BB), or by a disposable nuclear special reactor ...

        The mass of the "maneuvering" warhead Poplar is close to 1 ton, if we assume that the monoblock is capable of maneuvering under the influence of a lateral force of 10 N. Presumably, the maneuver time should be ~ 000 sec. Then the transverse displacement of the monoblock will be several meters. At a speed of about 1 km / s, the angular deviation of the warhead from the given trajectory will be of the order of 7.5 rad. The specific impulse of propellant (let's say hydrazine with nitrogen tetroxide) is 0.001 m / s, then for 3 second of thrust 000 N 3.33 kg of fuel will be spent.

        Total: "performing" ~ 100 maneuvers, each with a duration of ~ 1 sec, will cover ~ 2 km to the target and spent ~ 300 kg of fuel

        All this will "execute" 1 liquid-propellant rocket engine weighing ~ 100 kg or several such engines, each ~ 10 kg of weight.

        Warhead PK BR is not a poplar warhead, it cannot fly 9500km ..
        Accordingly, "on the knee":
        -50 kg BIP and THA (or something else, "chemistry" is permissible
        -50 kg radar

              The angle (angle) of the review of surface / ground targets from the head of the warhead / warhead of a ballistic missile on the descending part of the flight path is known - from 45 (RSD) to 30 (ICBM) degrees.

              The ESR of the ships in this range of angles is the maximum possible.

              In any case, the RCS of aircraft carriers and escort ships goes beyond reasonable limits - it seems that they can be drawn with the desired range (140 km) even with the help of the air-to-air missile RGSN (although I do not insist on this).

              The tactics of grouping the AUG into a characteristic combat order with the largest ship - an aircraft carrier in the middle helps to distinguish this ship formation from a convoy.

              Within a radius of 3000 km from the location of the over-the-horizon radar of the "Container" type, the AUG has one more distinguishing feature - radar marks on the presence of loitering aircraft in the air - AWACS and patrol fighters.

              RTR satellites capture radiation from radars of AWACS and air defense / missile destroyers for at least 3000 km.

              Well, nobody is going to refuse to escort the peaceful trawler of the GRU of the General Staff of the RF Armed Forces under the Cambodian flag at a distance of 1000 km from the AUG with reconnaissance UAVs on board.

              Therefore, the use of Liana / Pion radar satellites for tracking the AUG is optional.

          Just to reconnoiter, identify and transmit coordinates in the "window" of the theater (there are no many satellites), it will take up to 2 hours. during this time, AUG can go up to 120 km.

            This is how the satellite finds the carrier connection and transfers the coordinates to the ICBM warhead and, accordingly, to the command post - but no one has such a system, only the Voivode’s warheads have a radar, but it works only for stationary, already known and marked on electronic maps targets - scans the place of fall and compares it with the map for a more accurate hit. DF21 in a modern war is likely to be useless - in the event of a conflict with the United States, warheads will fly to China, then they will drive up the strike fleet and launch thousands of sea-based cruise missiles at maximum distance, and then bombing aircraft armed with bombs and again cruise missiles will go , carrier formations will approach the coast only when there is no stone on the enemy’s territory.

    Unfortunately, China does not seek to disclose the details of its bold projects
    And rightly so. The recently appeared fashion to write in the press the merits of new, often not yet adopted for service, models of equipment, looks rather strange. One of two things: either it’s a kind of misinformation, or the workers responsible for the regime of secrecy, full of nerds. The article is good, but precisely because of the lack of reliable information, the disputes surrounding Chinese RCC do not look very convincing. But it is clear that an attempt to bet on the defeat of ships exclusively by cruise missiles may prove to be flawed due to a number of drawbacks inherent in such missiles. It is not surprising that there are attempts to develop other means of destruction. And if such attempts are successful, they will undoubtedly attract the attention of specialists.

    The whole point of delirium is that actually a high-explosive shell falls onto a ship at a constant speed. which mza or core warhead does not hit. Only kinetic interception, but I have fantasized maneuvering on 5-7 max warheads, which kinetics have not yet been able to shoot down (and in the short term). And the GOS can generally fly along a different trajectory.
    Let's go through the masses again.
    A radar capable of detecting an aircraft carrier with 200 km. 400kg, 3-4 kW. Another 100kg 4kw power source for 5-7 minutes. Really?
    Warhead 600 kg of metal and TNT. Transceiver equipment 50 kg per eye. On the wheels honestly I honestly honestly do not know how much, 50 kg I think is enough. Accelerator, 500 kg.
    I think a kilogram of 1700-1800 all this stuff will weigh in the collection.
    A standard warhead weighs 700 kilograms. We weighted the warhead and lose 30-40% of the range, from 2500 to 1500.
    Even let the range decrease to a thousand kilometers. But we have the opportunity with high probability not even to hit, but to destroy the aug, before the first plane flies from the deck of an aircraft carrier to bomb the coast.

    And yet, yes, an analogue of the legend for the initial detection of targets is desirable. The identification issue is not at all worth it. Heaps of tank signatures are crammed into the Hellfire GOS. so I think this is not a question.

Submarines poke away from everything, quietly lying in the depths. Let the legend not immediately, not on the first day the aircraft carrier will detect. ((Carriers may hide from detection) America, like in 1988, hid for two weeks in the Pacific Ocean, although it was searched from space both by planes and ships.) But at the moment when the satellite detects the aug, an unrequited blow is delivered.

Needle type laid in a cone) also with a good lesion area, the ship may not be drowned, but it will be unambiguously withdrawn from combat condition. As you know, our over-the-horizon radars track all types of targets, so that we can also deliver a nuclear charge to any point, besides, we have introduced or are introducing a system for entering the coordinates of the targets of already launched missiles, and it is still not known to which portion of the flight they can be adjusted.
