§ 1.2 Fundamentals of Ritz Ballistic Theory There was a great need for an intermediate link that was invented to explain the reason for the equality of action and reaction. I stated in the introduction that radiant energy, generated and emitted at the speed of light,

The ICBM is a very impressive human creation. Huge size, thermonuclear power, column of flame, roar of engines and the menacing roar of launch. However, all this exists only on the ground and in the first minutes of launch. After they expire, the rocket ceases to exist. Further into the flight and to carry out the combat mission, only what remains of the rocket after acceleration is used - its payload.

With long launch ranges, the payload of an intercontinental ballistic missile extends into space for many hundreds of kilometers. It rises into the layer of low-orbit satellites, 1000-1200 km above the Earth, and is located among them for a short time, only slightly lagging behind their general run. And then it begins to slide down along an elliptical trajectory...

A ballistic missile consists of two main parts - the accelerating part and the other for the sake of which the acceleration is started. The accelerating part is a pair or three of large multi-ton stages, filled to capacity with fuel and with engines at the bottom. They give the necessary speed and direction to the movement of the other main part of the rocket - the head. The booster stages, replacing each other in the launch relay, accelerate this warhead in the direction of the area of ​​its future fall.

The head of a rocket is a complex load consisting of many elements. It contains a warhead (one or more), a platform on which these warheads are placed along with all other equipment (such as means of deceiving enemy radars and missile defenses), and a fairing. There is also fuel and compressed gases in the head part. The entire warhead will not fly to the target. It, like the ballistic missile itself earlier, will split into many elements and simply cease to exist as one. The fairing will separate from it not far from the launch area, during the operation of the second stage, and somewhere along the way it will fall. The platform will collapse upon entering the air of the impact area. Only one type of element will reach the target through the atmosphere. Warheads.

Up close, the warhead looks like an elongated cone, a meter or one and a half long, with a base as thick as a human torso. The nose of the cone is pointed or slightly blunt. This cone is special aircraft, whose task is to deliver weapons to the target. We'll come back to warheads later and take a closer look at them.

The head of the “Peacekeeper”, The photographs show the breeding stages of the American heavy ICBM LGM0118A Peacekeeper, also known as MX. The missile was equipped with ten 300 kt multiple warheads. The missile was withdrawn from service in 2005.

Pull or push?

In a missile, all warheads are located in the so-called breeding stage, or “bus”. Why bus? Because, having first been freed from the fairing, and then from the last booster stage, the propagation stage carries the warheads, like passengers, at given stops, along their trajectories, along which the deadly cones will disperse to their targets.

The “bus” is also called the combat stage, because its work determines the accuracy of pointing the warhead to the target point, and therefore combat effectiveness. The propagation stage and its operation is one of the biggest secrets in a rocket. But we will still take a slight, schematic look at this mysterious step and its difficult dance in space.

The dilution stage has different shapes. Most often, it looks like a round stump or a wide loaf of bread, on which warheads are mounted on top, points forward, each on its own spring pusher. The warheads are pre-positioned at precise separation angles (at the missile base, manually, using theodolites) and face different sides, like a bunch of carrots, like a hedgehog’s needles. The platform, bristling with warheads, occupies a given position in flight, gyro-stabilized in space. And at the right moments, warheads are pushed out of it one by one. They are ejected immediately after completion of acceleration and separation from the last accelerating stage. Until (you never know?) they shot down this entire undiluted hive with anti-missile weapons or something on board the breeding stage failed.

But this happened before, at the dawn of multiple warheads. Now breeding presents a completely different picture. If earlier the warheads “stuck” forward, now the stage itself is in front along the course, and the warheads hang from below, with their tops back, inverted, like bats. The “bus” itself in some rockets also lies upside down, in a special recess in the upper stage of the rocket. Now, after separation, the breeding stage does not push, but drags the warheads along with it. Moreover, it drags, resting against its four “paws” placed crosswise, deployed in front. At the ends of these metal legs are rearward-facing thrust nozzles for the expansion stage. After separation from the accelerating stage, the “bus” very accurately, precisely sets its movement in the beginning of space with the help of its own powerful guidance system. He himself occupies the exact path of the next warhead - its individual path.

Then the special inertia-free locks that held the next detachable warhead are opened. And not even separated, but simply now no longer connected with the stage, the warhead remains motionless hanging here, in complete weightlessness. The moments of her own flight began and flowed by. Like one individual berry next to a bunch of grapes with other warhead grapes not yet plucked from the stage by the breeding process.

Fiery Ten, K-551 “Vladimir Monomakh” is a Russian strategic nuclear submarine (Project 955 “Borey”), armed with 16 solid-fuel Bulava ICBMs with ten multiple warheads.

Delicate movements

Now the task of the stage is to crawl away from the warhead as delicately as possible, without disturbing its precisely set (targeted) movement with gas jets of its nozzles. If a supersonic nozzle jet hits a separated warhead, it will inevitably add its own additive to the parameters of its movement. Over the subsequent flight time (which is half an hour to fifty minutes, depending on the launch range), the warhead will drift from this exhaust “slap” of the jet half a kilometer to a kilometer sideways from the target, or even further. It will drift without obstacles: there is space, they slapped it - it floated, not being held back by anything. But is a kilometer sideways accurate today?

To avoid such effects, it is precisely the four upper “legs” with engines that are spaced apart to the sides that are needed. The stage is, as it were, pulled forward on them so that the exhaust jets go to the sides and cannot catch the warhead separated by the belly of the stage. All thrust is divided between four nozzles, which reduces the power of each individual jet. There are other features too. For example, if there is a donut-shaped propulsion stage (with a void in the middle - with this hole it is put on the rocket’s upper stage, like wedding ring finger) of the Trident-II D5 missile, the control system determines that the separated warhead still falls under the exhaust of one of the nozzles, then the control system turns off this nozzle. Silences the warhead.

The stage, gently, like a mother from the cradle of a sleeping child, fearing to disturb his peace, tiptoes away into space on the three remaining nozzles in low thrust mode, and the warhead remains on the aiming trajectory. Then the “donut” stage with the cross of the thrust nozzles is rotated around the axis so that the warhead comes out from under the zone of the torch of the switched off nozzle. Now the stage moves away from the remaining warhead on all four nozzles, but for now also at low throttle. When a sufficient distance is reached, the main thrust is turned on, and the stage vigorously moves into the area of ​​the target trajectory of the next warhead. There it slows down in a calculated manner and again very precisely sets the parameters of its movement, after which it separates the next warhead from itself. And so on - until it lands each warhead on its trajectory. This process is fast, much faster than you read about it. In one and a half to two minutes, the combat stage deploys a dozen warheads.

The abysses of mathematics

Intercontinental ballistic missile R-36M Voevoda Voevoda,

What has been said above is quite enough to understand how a warhead’s own path begins. But if you open the door a little wider and look a little deeper, you will notice that today the rotation in space of the breeding stage carrying the warhead is an area of ​​​​application of quaternion calculus, where the on-board attitude control system processes the measured parameters of its movement with a continuous construction on board the orientation quaternion. Quaternion is such a complex number (over the field complex numbers lies a flat body of quaternions, as mathematicians would say in their precise language of definitions). But not with the usual two parts, real and imaginary, but with one real and three imaginary. In total, the quaternion has four parts, which, in fact, is what the Latin root quatro says.

The dilution stage does its job quite low, immediately after the boost stages are turned off. That is, at an altitude of 100−150 km. And there is also the influence of gravitational anomalies on the Earth’s surface, heterogeneities in the even gravitational field surrounding the Earth. Where are they from? From uneven terrain, mountain systems, occurrence of rocks of different densities, oceanic depressions. Gravitational anomalies either attract the stage to themselves with additional attraction, or, conversely, slightly release it from the Earth.

In such heterogeneities, complex ripples of local gravitational field, the breeding stage must position the warheads with precision accuracy. To do this, it was necessary to create a more detailed map of the Earth's gravitational field. It is better to “explain” the features of a real field in systems of differential equations that describe precise ballistic motion. These are large, capacious (to include details) systems of several thousand differential equations, with several tens of thousands of constant numbers. And the gravitational field itself at low altitudes, in the immediate near-Earth region, is considered as a joint attraction of several hundred point masses of different “weights” located near the center of the Earth in in a certain order. This achieves a more accurate simulation of the Earth's real gravitational field along the rocket's flight path. And more accurate operation of the flight control system with it. And also... but that's enough! - Let's not look further and close the door; What has been said is enough for us.

Flight without warheads

The photo shows the launch of a Trident II intercontinental missile (USA) from a submarine. Currently, Trident is the only family of ICBMs whose missiles are installed on American submarines. The maximum throwing weight is 2800 kg.

The breeding stage, accelerated by the missile towards the same geographical area where the warheads should fall, continues its flight along with them. After all, she can’t fall behind, and why should she? After disengaging the warheads, the stage urgently attends to other matters. She moves away from the warheads, knowing in advance that she will fly a little differently from the warheads, and not wanting to disturb them. The breeding stage also devotes all its further actions to warheads. This maternal desire to protect the flight of her “children” in every possible way continues for the rest of her short life.

Short, but intense.

The ICBM payload spends most of its flight in space object mode, rising to an altitude three times the height of the ISS. The trajectory of enormous length must be calculated with extreme precision.

After the separated warheads, it is the turn of other wards. The most amusing things begin to fly away from the steps. Like a magician, she releases into space many inflating balloons, some metallic things that resemble open scissors, and objects of all sorts of other shapes. Durable balloons sparkle brightly in the cosmic sun with the mercury shine of a metallized surface. They are quite large, some shaped like warheads flying nearby. Their aluminum-coated surface reflects a radar signal from a distance in much the same way as the warhead body. Enemy ground radars will perceive these inflatable warheads as well as real ones. Of course, in the very first moments of entering the atmosphere, these balls will fall behind and immediately burst. But before that, they will distract and load the computing power of ground-based radars - both long-range detection and guidance anti-missile systems. In ballistic missile interceptor parlance, this is called “complicating the current ballistic environment.” And the entire heavenly army, inexorably moving towards the fall area, including combat units real and false, balloons, dipole and corner reflectors, this whole motley flock is called “multiple ballistic targets in a complicated ballistic environment.”

The metal scissors open up and become electric dipole reflectors - there are many of them, and they well reflect the radio signal of the long-range missile detection radar beam probing them. Instead of the ten desired fat ducks, the radar sees a huge blurry flock of small sparrows, in which it is difficult to make out anything. Devices of all shapes and sizes reflect different lengths waves

In addition to all this tinsel, the stage can theoretically itself emit radio signals that interfere with the targeting of enemy anti-missile missiles. Or distract them with yourself. In the end, you never know what she can do - after all, a whole stage is flying, large and complex, why not load it with a good solo program?

Last segment

Underwater Sword of America, American submarines The Ohio class is the only type of missile carrier in service with the United States. Carries on board 24 ballistic missiles with MIRVed Trident-II (D5). The number of warheads (depending on power) is 8 or 16.

However, from an aerodynamic point of view, the stage is not a warhead. If that one is a small and heavy narrow carrot, then the stage is an empty, vast bucket, with echoing empty fuel tanks, a large, streamlined body and a lack of orientation in the flow that is beginning to flow. With its wide body and decent windage, the stage responds much earlier to the first blows of the oncoming flow. The warheads also unfold along the flow, piercing the atmosphere with the least aerodynamic resistance. The step leans into the air with its vast sides and bottoms as necessary. It cannot fight the braking force of the flow. Its ballistic coefficient - an “alloy” of massiveness and compactness - is much worse than a warhead. Immediately and strongly it begins to slow down and lag behind the warheads. But the forces of the flow increase inexorably, and at the same time the temperature warms up the thin, unprotected metal, depriving it of its strength. The remaining fuel boils merrily in the hot tanks. Finally, the hull structure loses stability under the aerodynamic load that compresses it. Overload helps to destroy the bulkheads inside. Crack! Hurry! The crumpled body is immediately engulfed by hypersonic shock waves, tearing the stage into pieces and scattering them. After flying a little in the condensing air, the pieces again break into smaller fragments. Remaining fuel reacts instantly. Flying fragments of structural elements made of magnesium alloys are ignited by hot air and instantly burn with a blinding flash, similar to a camera flash - it’s not for nothing that magnesium was set on fire in the first photo flashes!

Time does not stand still.

Raytheon, Lockheed Martin and Boeing completed the first and key stage, associated with the development of a defensive exoatmospheric kinetic interceptor (Exoatmospheric Kill Vehicle, EKV), which is an integral part of the mega-project - a global missile defense system being developed by the Pentagon, based on missile defense, each of which is capable of carrying SEVERAL kinetic interception warheads (Multiple Kill Vehicle, MKV) to destroy ICBMs with multiple warheads and decoy warheads

"The milestone achieved is an important part of the concept development phase," Raytheon said, adding that it is "consistent with MDA plans and is the basis for further concept approval planned for December."

It is noted that Raytheon this project uses the experience of creating EKV, which is involved in the American global missile defense system, which has been operating since 2005 - the Ground-Based Midcourse Defense (GBMD), which is designed to intercept intercontinental ballistic missiles and their warheads in outer space outside the Earth's atmosphere. Currently, 30 interceptor missiles are deployed in Alaska and California to protect the continental United States, and another 15 missiles are planned to be deployed by 2017.

The transatmospheric kinetic interceptor, which will become the basis for the currently being created MKV, is the main destructive element of the GBMD complex. A 64-kilogram projectile is launched by an anti-missile missile into outer space, where it intercepts and contact destroys an enemy warhead thanks to an electro-optical guidance system, protected from extraneous light by a special casing and automatic filters. The interceptor receives target designation from ground-based radars, establishes sensory contact with the warhead and aims at it, maneuvering in outer space using rocket engines. The warhead is hit by a frontal ram on a collision course with a combined speed of 17 km/s: the interceptor flies at a speed of 10 km/s, the ICBM warhead at a speed of 5-7 km/s. Kinetic energy a strike of about 1 ton of TNT is enough to completely destroy a warhead of any conceivable design, and in such a way that the warhead is completely destroyed.

In 2009, the United States suspended the development of a program to combat multiple warheads due to the extreme complexity of producing the breeding unit mechanism. However, this year the program was revived. According to Newsader analysis, this is due to increased aggression from Russia and corresponding threats to use nuclear weapons, which have been expressed more than once by senior officials of the Russian Federation, including President Vladimir Putin himself, who, in a commentary on the situation with the annexation of Crimea, openly admitted that he was allegedly ready to use nuclear weapons in a possible conflict with NATO ( latest events related to the destruction of a Russian bomber by the Turkish Air Force, cast doubt on Putin’s sincerity and suggest a “nuclear bluff” on his part). Meanwhile, as is known, Russia is the only state in the world that allegedly possesses ballistic missiles with multiple nuclear warheads, including “false” (distracting) ones.

Raytheon said that their brainchild will be capable of destroying several objects at once using an improved sensor and other latest technologies. According to the company, during the time that passed between the implementation of the Standard Missile-3 and EKV projects, the developers managed to achieve a record performance in intercepting training targets in space - more than 30, which exceeds the performance of competitors.

Russia is also not standing still.

According to open sources, this year the first launch of the new RS-28 Sarmat intercontinental ballistic missile will take place, which should replace the previous generation of RS-20A missiles, known according to NATO classification as “Satan”, but in our country as “Voevoda” .

The RS-20A ballistic missile (ICBM) development program was implemented as part of the “guaranteed retaliatory strike” strategy. President Ronald Reagan's policy of exacerbating the confrontation between the USSR and the USA forced him to take adequate response measures to cool the ardor of the "hawks" from the presidential administration and the Pentagon. American strategists believed that they were quite capable of ensuring such a level of protection for their country’s territory from an attack by Soviet ICBMs that they could simply not give a damn about the international agreements reached and continue to improve their own nuclear potential and missile defense systems (ABM). “Voevoda” was just another “asymmetric response” to Washington’s actions.

The most unpleasant surprise for the Americans was the rocket's fissile warhead, which contained 10 elements, each of which carried an atomic charge with a capacity of up to 750 kilotons of TNT. For example, bombs were dropped on Hiroshima and Nagasaki with a yield of “only” 18-20 kilotons. Such warheads were capable of penetrating the then-American missile defense systems; in addition, the infrastructure supporting missile launching was also improved.

The development of a new ICBM is intended to solve several problems at once: first, to replace the Voyevoda, whose capabilities to overcome modern American missile defense (BMD) have decreased; secondly, to solve the problem of dependence of domestic industry on Ukrainian enterprises, since the complex was developed in Dnepropetrovsk; finally, give an adequate response to the continuation of the missile defense deployment program in Europe and the Aegis system.

According to expectations The National Interesting, the Sarmat missile will weigh at least 100 tons, and the mass of its warhead can reach 10 tons. This means, the publication continues, that the rocket will be able to carry up to 15 multiple thermonuclear warheads.
“The Sarmat’s range will be at least 9,500 kilometers. When it is put into service, it will be the largest missile in world history,” the article notes.

According to reports in the press, NPO Energomash will become the head enterprise for the production of the rocket, and the engines will be supplied by Perm-based Proton-PM.

The main difference between Sarmat and Voevoda is the ability to launch warheads into a circular orbit, which sharply reduces range restrictions; with this launch method, you can attack enemy territory not along the shortest trajectory, but along any and from any direction - not only through the North Pole , but also through Yuzhny.

In addition, the designers promise that the idea of ​​​​maneuvering warheads will be implemented, which will make it possible to counter all types of existing anti-missile missiles and promising systems using laser weapon. Anti-aircraft missiles"Patriot", which form the basis of the American missile defense system, cannot yet effectively combat actively maneuvering targets flying at speeds close to hypersonic.
Maneuvering warheads promise to become so effective weapon, against which there are currently no means of counteraction equal in reliability, that the option of creating an international agreement prohibiting or significantly limiting this type weapons.

Thus, together with sea-based and mobile missiles railway complexes"Sarmat" will become an additional and quite effective deterrent factor.

If this happens, efforts to deploy missile defense systems in Europe may be in vain, since the missile's launch trajectory is such that it is unclear where exactly the warheads will be aimed.

It is also reported that the missile silos will be equipped with additional protection against close explosions of nuclear weapons, which will significantly increase the reliability of the entire system.

First prototypes new rocket have already been built. The start of launch tests is scheduled for this year. If the tests are successful, serial production of Sarmat missiles will begin, and they will enter service in 2018.
