Since the sixties of the last century, our scientific and design organizations have been dealing with the topic of combat lasers. Over the past few decades, a number of projects of such weapons have been developed, designed to solve various problems. Some of the projects were brought to testing, and the latest samples even went into operation. The development of a promising direction continues, and several important trends can be noted in it.



История вопроса


The development of the first domestic combat laser began almost 60 years ago, in 1964. The goal of the program under the code "Terra" was to create a laser missile defense system capable of hitting ballistic missile warheads. Soon the Omega project was launched, the result of which was to be a laser air defense system. Both samples reached the test, but showed limited performance, and they were not accepted into service.

In the XNUMXs, the issue of using lasers in space was studied. The combat laser was planned to be placed on the Skif-D orbital station. Depending on the tasks at hand, this weapon was supposed to suppress, disable or destroy enemy spacecraft. Due to the overall complexity and changes in plans, this project did not progress further than development.

At the beginning of the next decade, the first combat lasers appeared, designed for use on the battlefield. The first to be tested was the self-propelled laser complex (SLK) 1K11 "Stiletto" on a tracked chassis. It was intended to suppress or destroy ground-based optical reconnaissance equipment. Then came the Sanguine complex for military air defense, made on the basis of the ZSU-23-4 self-propelled gun. His task was to influence the optics of aircraft and helicopters. The last SLK of that period was the 1K17 Compression, designed to work on ground targets.

SLCs of these types, with all their advantages, had a number of disadvantages. Due to the imperfection of technology, they were complex and expensive, both in production and in operation. At the same time, the combat characteristics did not fully meet expectations.

Also in the eighties, two A-60 flying laboratories were built. These were Il-76 military transport aircraft with combat lasers based on developments on the Skif-D theme. Two aircraft participated in versatile testing and research. In the nineties, the A-60 project was suspended, but already in the XNUMXs, new experiments began.

Modern developments


After the collapse of the USSR, work on weapons based on new physical principles slowed down markedly. Nevertheless, in the future, science and industry were able to resume work and even obtain new results. First of all, they continued experimenting with existing technology. In addition, as it became known later, completely new samples were created.

So, in 2018, a mobile laser complex was presented for the first time, which later received the name Peresvet. By this time, the product managed to enter the troops and was in trial operation. Tests in Syria were later reported. According to known data, "Peresvets" are used in the interests of the strategic missile forces and provide protection for missile systems and position areas from reconnaissance satellites of a potential enemy.

Since 2017, the Zadira-16 development work has been carried out, the purpose of which was to create a SLK for air defense on a modern component base. In May 2022, it became known that this complex had not only reached testing, but had also been tested in the zone of the Special Operation. Zadira-16 is used to combat small UAVs. Depending on various factors, such targets are suppressed or literally burned.

Limitations and solutions


The development of any combat laser and obtaining the desired characteristics are always associated with certain technical and technological limitations. Due to this story the creation of such weapons is actually a continuous search for new solutions to cope with the limitations and obtain the desired result.

To effectively hit the target, the laser power must correspond to the working distances and features of the attacked object. This determines the requirements for the design of the laser itself and for the means of power supply. At the same time, the current level of technology and available components are of great importance. All these factors have had a significant impact on the history of domestic projects.

So, the first Soviet complex "Terra" was created as a missile defense system, and it required a particularly high radiation power. This problem was solved, but due to the imperfection of technologies in the field of lasers and power supply, the complex had to be made in the form of several large stationary structures.

In the future, the industry took up lasers of lower power. The reduction in combat performance and new developments made it possible to reduce the radiating part and simplify the means of power supply. As a result, new generation complexes could already be placed on self-propelled tracked chassis or even on space carriers.

Against the background of the developments of the past, the modern Peresvet complex looks curious. As far as we know, it must work on orbital targets, which places high demands on the power and accuracy of the laser. In this case, only target suppression occurs, which limits the required power. The modern component base and new technologies made it possible to make the “anti-space” laser complex mobile. All his funds fit on several trailers, which distinguishes him from the early "Terra" and "Omega".

Means of defense


It is easy to see that the domestic industry has developed combat lasers for various purposes. Complexes of different types were supposed to hit or suppress ballistic, aerodynamic and ground targets. In the future, we accumulated the necessary experience, and the customer revised his plans for laser systems. As a result, lasers have gone out of several realms, but are finding their place in others.

The early projects of stationary air defense and missile defense systems, unfortunately, did not give the desired result. Experiments have shown that defeating the warhead of a ballistic missile with a modern laser for that period is an extremely difficult task. Work on air targets was also associated with certain difficulties and limitations.

Ground-based SLCs performed better during tests. They successfully suppressed the optics of a mock enemy, both on ground and on air platforms. However, the imperfection of technology limited combat performance. The complexes were unacceptably expensive for mass production and full implementation in the troops. In addition, the very need for such SLKs was in question - it was possible to fight enemy reconnaissance means by any existing means.

Obviously, the experience of the past decades was taken into account in the preparation of modern plans and in the development of current projects. So, it was decided to abandon the use of lasers in missile defense and "big" air defense. In addition, the army is no longer interested in SLK to suppress the optics of ground vehicles. Attention and efforts are focused on other areas.

The concept, previously implemented in the Sanguine project, was developed. The modern Zadira-16 complex, like its predecessor, is designed to work on air targets. At the same time, in accordance with current trends and the situation, UAVs become its main targets. The complex is able to suppress or disable their optics. In addition, under optimal conditions, the beam power is enough to destroy the structure.

Mobile "Peresvet", apparently, has no direct predecessor in domestic practice. According to known data, its main task is to suppress optical reconnaissance satellites. In the past, such tasks were assigned to the developed orbital stations, and it was also about the destruction of the intended targets.

With maximum result


Thus, over the past decades, domestic science and industry have accumulated solid experience in the field of combat lasers and continue to develop this area. In recent years, two modern developments of this kind have been created and revealed, and it can be expected that in the near future they will talk about new samples of this or that purpose.

Over the past 60 years, various concepts and designs have been developed and implemented. Some of them have not progressed beyond the project or laboratory tests, while others have been fully tested in the form of prototypes. All these works and activities made it possible to determine the real potential of different ideas, concepts and samples.

Based on the results of research and testing, it was decided to abandon some of the concepts due to their complexity or inappropriateness. At the same time, viable areas are being developed, and samples of such classes are even entering service. At the same time, it is proposed to introduce combat lasers not in all areas, but only where they are able to show the maximum result. This approach has already led to the emergence of two complexes for combating satellites and UAVs - and they are unlikely to be the last.

      They also talked about quadrocopters and small UAVs - how did it end? It is unrealistic to assess the prospect of a new weapon in advance. And it’s better to work on your weapons than to overpay for purchases abroad along the way, paying with the lives of soldiers.

        UPDATE.
        If each cartridge is made with electronic filling and with steering nozzles (or taxiing by attraction to a laser beam). And at the same time aim at the optics with a multiple zoom, and the accuracy of the shot at the laser beam, but the laser should not constantly shine, but only at the moment of the shot, so that the enemy does not detect the fighter ahead of time.

        This means that cartridges in the future will be filled with electronics, the insides will be in nanometers, printed in high-precision printers.

        The light weight of the cartridges will increase their number in the store, for example 1 million pieces, or 1 billion pieces. Reloading will rarely be needed.

        It is not in vain that the production of printer toner by chemical synthesis is done in microscale by the Americans, these developments can also be used in military needs, only the synthesis of other substances will be. There is a cheaper method of producing toner, and they choose a more complex technology because it is dual-use (more promising for the future) ...

      Suppression of visual intelligence - primarily commercial UAVs. It may not be enough to bring down the power, but to knock out the matrix of an ordinary camera - completely. And you will have to switch to military products with their filters and protection - and this is completely different money and dimensions ..

        You can burn out the matrix if only the optical axes of the emitter and the UAV lens coincided, which is unlikely, you can light up, but on the other hand, you identified yourself (wait for the arrival). So far, lasers for ground-based suppression are a utopia. They can work in space, there is no atmosphere, but I’m not sure that this is the best option in terms of cost / efficiency (more precisely, EMP from a thermonuclear explosion or tungsten shot).

        with that level of necessary energy, you can stir up such a radar ... but it’s better all the same balloons / multitortors with a photonics complex.
        kmk the whole point of precisely the energy defeat is in the speed of switching between targets and the consumption of ammo. I must say that the defeat itself is not necessarily a laser, but it is possible to increase the signature with it and inform the executive modules about the motion vectors, coordinates.

        In fact, M-theory (the most advanced version of superstring theory) speaks of exactly 11 dimensions. The trouble is that we have neither experimental verification (it would require an accelerator the size of either a galaxy or the visible universe, depending on how you count), nor normal mathematics (only approximate solutions of approximate equations). You can only catch subtle effects like a short-term violation of conservation laws due to the fact that during the collision the particle temporarily falls into curled dimensions. Why bother with such a theory? In it, gravity is derived mathematically, and not introduced as a fact (the importance of this can be understood if we consider that the two main physical theories today (general relativity and the standard theory of microparticles) are mathematically incompatible with each other, that is, the experiment can be calculated, but analytically solve - figurines (gravity, bastard, is not quantized in any good way, although both are confirmed experimentally with very high accuracy) and, if successful, it will be possible to mathematically derive the values ​​​​of the main constants of our universe from how exactly the folded dimensions are folded. Plus, due to the fact that the process of particle interaction there is not instantaneous, many infinities disappear, which had to be removed by normalization.

    One of the promising areas in the creation of combat laser systems is fiber lasers! Almost all (or "almost" all ...) mobile laser "guns" abroad are "built" using this technology ... But in Russia this technology is "not very"! (A fan of fiber lasers "at one time" left Russia, taking with him the most capable employees, and is working "for the good of NATO" abroad ...) And by and large, those laser technologies that originated and were being developed are being developed in Russia once in the USSR ... that is, not the latest! In general, it is certainly possible to create laser "guns"; but there is an assumption that they will be inferior to foreign ones in terms of weight and size characteristics! Although, now I "rely" on information that is ... 10 years old! Maybe something is changing now!

      As far as I know, fiber and solid-state lasers have a power of tens of kW, which is only enough to damage light drones and disable vulnerable units (optics, antennas, etc.). Lasers for the destruction of serious objects, like the same warheads, with a much higher power, were developed on the basis of chemical or nuclear pumping.

      in physical principles.
      The laser can be simply described as a polarizing filter. Powerful radiation from the "lamp" hits it on one side, and only a part corresponding to the required parameters comes out on the other side. This part falls on the focusing system.
      The ratio of light power before and after -- efficiency. The efficiency is specific to the laser itself and the overall efficiency of the system. The efficiency of even the most economical lasers is no more than 30%. That is, if you "shine on the laser" with a kilowatt "lamp", it will give out no more than 330 watts of light. In theory. Maximum. But after all, the "lamp" also does not burn by itself. She also needs to be fed. For example, a generator. Which also has efficiency. As a result, the radiation efficiency of laser weapons is generally reduced to 10-20%.
      And this is "on the cut of the trunk"
      Now this light needs to be focused. Apply to the lens. The lens also absorbs some of the radiation and heats up. In this case, the glass of the lens is deformed, the glass is not a solid substance, it is essentially a very thick liquid, it needs to be cooled, which also reduces the overall efficiency of the system.

      After the lens, the beam travels through the air. Air is a bunch of gas molecules, each of which absorbs a portion of the light. At the same time, it is so strong that it turns into a plasma on the way of the beam. This also reduces the efficiency of the system.

      The air is not sterile. It may contain suspended impurities. First of all, water. In the form of small drops, which, firstly, reflect part of the light, and secondly, absorb part of the beam power, turning into vapor, and then decomposing. It is very easy to understand how much this will affect the laser: look at the clouds and clouds. Can you see through them? No. So the laser will not pass through them.
      But the worst thing is not the water. And finely dispersed solid particles are dust. This is generally a wall for the laser.

      As a result, during real tests of combat systems, it turned out that about 5% of the expended generator power reaches the target surface. In particular, such parameters were obtained during testing of Soviet shipboard lasers.

      In addition, there is a physical limit to the growth of power. At a certain level of beam power, the air on its path goes into a plasma state, which leads to beam defocusing. Instead of a powerful weapon, you get a beautiful special. the effect is a "Jedi sword" that dumps all energy above a certain threshold into nowhere.

      Well, one more moment. The beam propagates in a straight line. This means that you cannot hit a target beyond the horizon. You can shoot either from top to bottom, or from bottom to top, or in the sky.

      Something like this. Extremely simplified. And I have not yet touched on changes in the state of the working body of the laser itself. It's not easy either...

        This is on the one hand. On the other hand, at a high power of the laser beam, those factors that are too small in the classical case begin to influence (because the classic is the result of expanding the general formula into a series and discarding any nonlinearity of the second or more orders, which is usually considered equal to zero at low intensity) . And suddenly the laser beam begins to noticeably change the refractive index of the medium in which it propagates, changing the direction of propagation or self-focusing with subsequent divergence.

          Beam self-focusing occurs up to a certain power limit. Until the air becomes a degenerate gas. And on the path of the beam, in fact, an optical waveguide such as a fiber optic cable is obtained. The appearance of plasma reverses the situation, the "waveguide" turns inside out, as it were, and defocusing of the beam begins. Hence the "Jedi sword" light on the boundary of the media is reflected outward.

      What is the growth in the effectiveness of laser weapons?

      In atmosphere. The air heated by the beam expands, a so-called "light-detonation wave" arises - which, in addition to a strong roar, can also damage the laser. Moreover, the process is avalanche-like - heated air absorbs more beam energy, becomes less transparent like any plasma, absorbs even more, and in general, if a certain power is exceeded, nothing will reach the target at all, but the mirror and the installation itself will not be good.
      The second limitation is the reflection coefficient, which, of course, went beyond 99.5 percent for "laser" mirrors, unlike 90-95 for household ones, but with pulse power values ​​​​in megajoules, even one hundredth of a percent of the beam power is one hundred watts ... which will be released in layer thickness of microns and in milliseconds. Why the coating darkens, loses its reflective properties, heats up more and collapses. Yes, carefully cleaned air is supplied to the mirror area to prevent dust from settling on it, and the mirror itself is cooled from behind, but still there is a certain limit.
      The third problem is the effect of the beam on the target, which again differs depending on the length of the pulse. Moreover, the "armor" from the laser is foil on polystyrene. The beam evaporates the foil, the vapors expand explosively, and the shock wave from these metal vapors is damped by the foam. This is very simplistic, but the general idea is that laser protection is different from shrapnel protection.

      Yes, and gravitational guns, as well as a local change in the structure of space-time can be used.
      Whack: and the satellite was smeared in a two-dimensional plane with thickness = 0, or Whack + Whack and the orbital grouping of the potential enemy went into 7 dimensions and collapsed there from internal stresses in the structure of atoms.
      I can offer to influence (locally) the quantum of the Higgs field.

    The direction is good, but devices like "Peresvet" cause fierce skepticism conceptually, in view of the latest trends in the work of the WTO at the front. If we assume that "Peresvet" "cuts satellites", then there is only one alignment (and the whole question is how effective the concept on such a chassis is for this task).
    If this is a system for combating (including) UAVs, then such a thing is a bad decision.
    As we have already seen - HIMARS and even, often, art, endure everything like this, such a massive and clumsy och. gracefully. So, at a distance capable of threatening an UAV, such a thing will itself be under the threat of other enemy means that can have a massive impact on it.

    As for the fight against satellites, a large aircraft flying at subsonic above the clouds and capable of operating LO from there looks much more interesting. Firstly, it is possible to organize cooling with outside air there, and secondly, there will be much less dependence on the atmosphere and, in principle, mobility and variability of application. Also, the fuselage is much larger and sleeker as a solution than the bulky and healthy high-floor chassis, an incredibly large and conspicuous thing from satellites. This is if against satellites.

    Against UAVs, you probably need some kind of modular solution, possibly dispersed over 3 cars. Definitely not one hefty "milk carrier", forget it.

    A hell of a lot of money has been spent on lasers in 60 years. What just did not stick under the leadership of Ustinov Jr. As engineer Garin did not succeed. There will be sense in 10 years from free electron lasers. A staff member who left Novosibirsk is working on them at Stanford.
