    It is all just further proof that the human race is a failed experiment... a doomsday bomb is the solution... or a good world wide plague that will kill 6 billion people perhaps...

It would make practical sense that a nuclear powered laser would also be a nuclear-pump-laser as well. It was confirmed the power was 1MW (like what I speculated) which leads me to believe that it is indeed Peresvet.

    In 2012, the source [1] reported that in the RFNC-VNIITF (Snezhinsk) a gas laser pumped by a nuclear reactor operating at the atomic xenon transition with a wavelength of 2.03 μm was created. The output energy of the laser pulse was 500 J at a peak power of 1.3 MW. This device is the most compact in terms of the volume of active gas medium used (specific laser radiation energy was 32 J / dm³)

    A 520 J pulsed gas laser (laser module) was created, pumped by fission products of uranium nuclei, operating at the atomic transition of xenon 5d [3/2] 1 -> 6p [3/2] 1 , with a wavelength of 2.03 mum. The experiments were carried out on the BARS-5 + RUN-2 complex (Fast aperiodic self-quenching reactor and Reactor neutron multiplier). The specific energy of laser radiation obtained in the experiments was ~ 32 J / dm 3 at an efficiency of ~ 3% (the ratio of the output energy of the laser pulse to the energy transferred to the gas medium by fission fragments).

    Some wild guesses here. But Im guessing one of the reasons why Peresvet's program got greenlighted is because the laser is boosted with other forms of electromagnetic radiation, including microwaves and gamma radiation, which might allow it to perform the duties of DEW and ECM all in one package. So theoretically speaking Peresvet may actually be both a Laser and a Maser.

    More on nuclear-pump lasers:


     

    Nuclear-pumped lasers






    Since the late 1960s, work began on the creation of high-power nuclear-pumped lasers in the USSR. Initially, the specialists of VNIIEF, IAE im. Kurchatov and Research Institute of Nuclear Physics, Moscow State University. Then scientists of MEPhI, ¬VNIITF, IPPE and other centers joined them. In 1972, the VNIIEF excited a mixture of helium and xenon with uranium fission fragments using the VIR 2 pulsed reactor

    . experiments are being conducted at the TIBR-1M reactor, in which the laser radiation power was about 1-2 kW. In 1975, on the basis of the VIR-2 pulsed reactor, a two-channel laser unit LUNA-2 was developed, which in 2005 still worked, and it is possible that it still works. In 1985, a neon laser was pumped for the first time in the world at the LUNA-2M installation.


    Peresvet laser complex - Page 8 1580459184_06-luna-2m
    LUNA-2M installation


    In the early 1980s, VNIIEF scientists, to create a nuclear-laser element operating in continuous mode, developed and manufactured a 4-channel laser module LM-4. The system is excited by a neutron flux from the BIGR reactor. The duration of the generation is determined by the duration of the irradiation pulse of the reactor. For the first time in the world, continuous generation in nuclear-pumped lasers was demonstrated in practice and the efficiency of the transverse gas pumping method was demonstrated. The laser power was about 100 watts.



    Peresvet laser complex - Page 8 1580459230_07-lm-4
    Installation LM-4


    In 2001, the LM-4 installation was modernized, receiving the designation LM-4M / BIGR. The operation of a multi-element nuclear laser device in continuous mode was demonstrated after 7 years of preservation of the installation without replacing optical and fuel cells. The LM-4 installation can be considered as a prototype reactor-laser (RL), possessing all its qualities, except for the possibility of a self-sustaining nuclear chain reaction.

    In 2007, instead of the LM-4 module, the eight-channel laser module LM-8 was put into operation, which provided for the sequential addition of four and two laser channels.



    Peresvet laser complex - Page 8 1580459264_08-lm-8
    Installation LM-8


    The laser reactor is an autonomous device that combines the functions of a laser system and a nuclear reactor. The active zone of a laser reactor is a set of a certain number of laser cells placed in a certain way in a neutron moderator matrix. The number of laser cells can range from hundreds to several thousand pieces. The total amount of uranium is from 5-7 kg to 40-70 kg, linear dimensions 2-5 m.

    VNIIEF carried out preliminary assessments of the main energy, nuclear-physical, technical and operational parameters of various versions of laser reactors with a laser radiation power of 100 kW and above, operating from fractions of a second to continuous operation. Reactor lasers with heat storage in the reactor core at start-ups, the duration of which is limited by the permissible heating of the AZ (heat-capacitive radar) and continuous radar with the removal of thermal energy outside the AZ



    Peresvet laser complex - Page 8 1580459269_09-reaktor-lazer
    Heat capacitive radar and continuous radar


    Presumably, a laser reactor with a laser power of about 1 MW should contain about 3,000 laser cells.

    In Russia, intensive work on nuclear-pumped lasers was carried out not only at VNIIEF, but also at the Federal State Unitary Enterprise State Scientific Center of the Russian Federation - A.I. Leipunsky ”, as evidenced by patent RU 2502140 for the creation of a“ laser-laser reactor with direct pumping of fission fragments. "

    Specialists of the SSC RF IPPE developed an energy prototype of a pulsed reactor-laser system - an optical nuclear-pumped quantum amplifier (OKUYAN).

    OKUYAN based on the BARS-6 reactor


    Remembering the statement of the Deputy Minister of Defense of Russia Yuri Borisov in the last year’s interview with the Krasnaya Zvezda newspaper (“We received laser systems that make it possible to disarm a potential enemy and hit all those objects that serve as the target for the laser beam of this system. Our nuclear scientists learned how to concentrate energy necessary to engage the respective arms of the enemy virtually instant, in a matter of seconds ") , we can say that the BLK" Relight "not equipped with small c Chassis Basic nuclear reactor, power supply laser, a laser reactor in which fission energy is directly converted into laser radiation.

    Only the aforementioned proposal makes it possible to place Peresvet BLK on an airplane. No matter how you ensure the reliability of the carrier aircraft, there is always a risk of an accident and a plane crash with the subsequent spread of radioactive materials. However, it is possible that there are ways to prevent the spread of radioactive materials when the carrier falls. And the flying petrel in a cruise missile cruise missile we already seem to have.

    Based on the foregoing, it can be assumed that the probability of the implementation of the Peresvet BLK in version 3 based on a nuclear-pumped laser can be estimated as high.

    It is not known whether the installed laser is pulsed or continuous. In the second case, the time of continuous operation of the laser and the breaks that must be carried out between the operating modes are in question. I would like to hope that a continuous laser reactor is installed in the Peresvet BLK, the operating time of which is limited only by the supply of refrigerant, or not limited if the cooling is provided in any other way.

    In this case, the output optical power of Peresvet BLK can be estimated in the range of 1-3 MW with the prospect of increasing to 5-10 MW. It is hardly possible to hit a nuclear warhead even with such a laser, and a plane, including an unmanned aerial vehicle, or a cruise missile, is completely. It is also possible to ensure the defeat of virtually any unprotected spacecraft in low orbits, and it is possible to damage sensitive elements of spacecraft and higher orbits.

    Thus, the first goal for Peresvet BLK may be the sensitive optical elements of the US missile attack warning satellites, which can act as an element of missile defense in the event of a US disruptive strike .


    conclusions




    As we said at the beginning of the article, there are a fairly large number of ways to obtain laser radiation. In addition to the ones discussed above, there are other types of lasers that can be effectively used in military affairs, for example, a free-electron laser, in which it is possible to widely vary the wavelength up to soft x-ray radiation and which just needs a lot of electric energy produced by small-sized nuclear reactor. Such a laser is being actively developed in the interests of the US Navy. However, the use of a free electron laser in Peresvet BLK is unlikely, because at present there is practically no information on the development of such lasers in Russia, apart from participation in Russia in the European free electron x-ray program.

    It must be understood that the assessment of the probability of applying one or another solution to the Peresvet BLK is given conditionally: the presence of only indirect information obtained from open sources does not allow us to draw conclusions with a high degree of reliability.

    It is possible that the conclusion about the high probability that the Peresvet BLK uses a laser with a nuclear pump is partially made not only on the basis of objective factors, but also on the underlying desire of the author. For if Russia really created a laser with a nuclear pumping power of megawatts or more, this opens up extremely interesting prospects for creating weapons systems that can radically change the face of the battlefield. But we will talk about this in another article.

    PS In order to eliminate questions and disputes about the influence of the atmosphere and weather on the operation of lasers, it is highly recommended to study the book by A. S. Boreisho, “Powerful Mobile Chemical Lasers,” at least Chapter 6, entitled “Propagation of Laser Radiation at Operational Distances”.

    ...So Peresvet may have a power output of 1-3 MW, with a potentially increase up to 10 MW output.

    Machine translation is always wonky....they're saying with enough power (say 10 MW) and with the right circumstances (like a flying platform at high altitude) it could potentially defeat them. Gorby the betrayer cancelled a space based program while the Yanks had Star Wars ongoing, which goes to show the guy with the bird poop birth mark was such a spineless loser. As Mindstorm has brought up, higher altitude (or even space based) laser platforms are completely different animal than land based laser platforms.

    A free-electron laser is an oxymoron. No charged particle beam can maintain any coherence since electric repulsion is huge
    and long range. Photons avoid this issue and do not have any upper bound on the density that can be produced and lased. Of course,
    at some stage the laser will simply evapourate if the photon density is too high. But even packing free electrons into a small volume
    is extremely self-limiting.

    It is rather clear that there have been several nuclear reactor advances in Russia that have given us Burevestnik and Peresvet.
    Some experiments from the 1960s are not a useful guide as to what sort of technology we are dealing with today. That is top
    secret and not a trivial variation of 1960s tech.

    The article chokes on the idea of flying a nuclear driven laser on a plane because of potential contamination during an accident.
    This is an example of small-think. During WWIII nobody will care about any contamination since there will be plenty of it coming
    from all the mushroom clouds. So if putting a nuclear laser in flight can save a city from being glassed, then no second thought
    will be given about deploying such a system. It is really simple cost vs. benefit analysis. Also, contaminated crash sites can be
    cleaned up. So all reservations and concerns about reactors crashing is just so much anti-nuclear hysteria.

    It is evident that the Peresvet system can be mounted on a jet. It is unlikely to weigh more than 30 tons. We also do not know
    if the current Peresvet reactor is the final variant. Burevestnik makes me think that some substantial progress has occurred in
    downsizing of reactors.

    It's interesting how people freak out about anything nuclear. People are afraid of nuclear material contaminating if there's a crash, but their not worried about a +100 ton aircraft full of kerosene crashing and causing a massive forest fire, which under the right conditions uncontrolled fires give you whats going on right now in Australia.

    The kerosene combustion products from a crash fire are full of carcinogens, mutagens and teratogens thanks to poor combustion.
    Human sheep think that chemicals are safer than radioactive substances. BS. There is no rule that makes radiation more dangerous
    than disruptive organic chemistry. There is dose dependence and radioactive compounds have half lives. By contrast, nasty organic
    chemicals can keep on being nasty even as they are oxidized with daughter products being no less damaging to health than the precursor.
    Conversion to CO2 and H2O takes a freaking long time and there are thousands of generations of thousands of daughter products from
    a single compound.

    BTW, firefighters have some of the highest death rates from cancer. Nuclear plant workers do not show any increased risk compared
    to the general population.

    Apparently Peresvet isn't just a means of attack, but also a means of detection. Apparently it was originally filed as a patent for a 'mobile optical telescope.'

    Probably something from the period of late 80's-2000's. I can see Peresvet being placed on it's vehicle chassis to increase mobility.

    Also a friendly reminder on Peresvet is (I posted this in another thread): Peresvet is likely a hybrid DEW/ECM, a Laser/Maser/Graser combination to not just melt/burn munitions with a intense pencil beam Laser, and with the Maser (focused microwaves) and Graser (focused gamma radiation beam) to fry the electronics by inducing high current electromagnetic electrostatic discharge, like a direct beam EMP.

    Interesting article on Peresevet (and the airborne Sokol-Eshelon and fixed-facility Kalina):

    https://www.thespacereview.com/article/3967/1

    Interesting exerts:

    Another key subcontractor to RFYaTs-VNIIEF that can be identified from this documentation is NII NPO Luch in Podolsk (Moscow region), yet another organization belonging to Rosatom. It is responsible for an adaptive optics system needed to compensate for atmospheric turbulence that the laser beam encounters on its way to space.[19] Adaptive optics systems typically use a beacon illuminator laser that creates an artificial guide star by shining a low-power laser into the atmosphere. Light from the beam is then reflected back by components in the upper atmosphere and measured by a so-called wavefront sensor that determines atmospheric turbulence between the laser complex and the target. This information is then used to drive the adaptive optics, which consist of one or more deformable mirrors that can adjust the high-power laser beam that is subsequently aimed at the target. The use of an adaptive optics system also reduces the time that the laser needs to be maintained on the target to achieve its goal.

    The exact type of high-power laser used by Peresvet remains known. One Russian analyst recently concluded that the most likely type was a nuclear-pumped laser, among other things because of RFYaTs-VNIIEF’s close involvement in the country’s nuclear weapons program.[21] Another recent Russian article, citing only “scientific forums,” says Peresvet most likely uses an explosively pumped iodine photodissociation laser, a type of laser in which a detonator is activated to dissociate perfluoroalkalyl iodides in the gain medium and raise the resulting iodine atoms to the energy levels needed to produce a laser beam.[22] RFYaTs-VNIIEF has a long history experimenting with this type of laser and considered it for use in the Soviet-era Terra-3 laser complex, an anti-missile laser system that never reached operational status. It is also the one recommended for use in the 2013 RFYaTs-VNIIEF patent that is likely related to Peresvet. The patent holders, several of whom have a background in the development of this type of laser, claim it has a longer range than two other types that could potentially be used, namely alkali metal vapor lasers and fiber lasers. The reasons given for that are its ability to work in pulsed rather than continuous wave mode and its operating wavelength (1.315 µm, in the near infrared), which allows the beam to easily pass through the atmosphere.

    Work continues on ground support facilities for Peresvet under contracts signed between the Ministry of Defense of Russia and the military construction company Main Military Construction Directorate No. 5 (GVSU No. 5) on October 10, 2017 and June 14, 2018. This can be done from contracts published on the Russian public procurement website, which contain the index 14TS034 and list objects with the designation “2146”. Four of the deployment facilities of the Peresvet complex can now be identified by existing contracts:

    2146/1: in the 54th missile division near Teykovo
    2146/2: in the 39th missile division near Novosibirsk
    2146/3: in the 35th missile division near Barnaul
    2146/5: in the 14th missile division near Yoshkar-Ola

    The existence of the Peresvet deployment facility near Barnaul (in the Altai Territory) was not previously known. Shelter for laser systems can be seen on Google Earth west of the closed military town of Siberian, located about 25 kilometers north of Barnaul. The location of another object (2146/4) remains unknown at present. The only other strategic missile forces armed with Yars missiles are the 29th missile division near Irkutsk and the 42nd missile division near Nizhny Tagil, but the current images do not show cover for laser systems in these areas.

    The last missing “Peresvet” was found in Nizhny Tagil, at 42 missile division in the 142 missile regiment (58.13396N 60.52202E). Proubably it's called "object 2146/4" ("объект 2146/4" at russian).

    What is interesting is that the vehicle actually looks like a TOPOL ICBM launch TEL vehicle.

    They also make a large refuelling truck the same shape as the TOPOL TEL so groups of vehicles can go on extended drives anywhere they like... they have extra vehicles the same shape as the TELs that can be used as accommodation for the crews and command units, plus also fuel in the refuelling trucks and of course convoy escort vehicles... I would think the current Vodnik type vehicles could be replaced by something with an automatic 57mm grenade launcher or high velocity gun... obviously their focus will be to get to a safe place and launch their missiles as quickly as possible and then perhaps scatter.

    Would make an interesting computer game... Trump wants coffee at 3am near the end of his third term in office (he is an evil dictator of course and the bad guy in the game...) and accidentaly pushes the red button and starts WWIII... you are a soldier in a TOPOL or Yars unit... you launch your missiles and then your unit splits up... you have a fuel truck and large trucks that can accommodate a group of armed men. Head to the Urals to some secret base there in the mountains and wait things out... After a few years and the dust has settled you head out to find what survived... a bit like Exodus I suppose but perhaps more positive... much less destruction. It then becomes a case of establishing communication with various cities and restoring Russia back to something that can feed its people and defend its new borders....

    Well that could be interesting, a while back I has a similar idea only you would be on a missile cruiser and go to the southern hemisphere till the radiation cleared.

    It would be very interesting to have a realistic post nuclear game from the point of view of a soldier or officer, the closest game I can think of is cuban missile crisis though that is an RTS.

    If you want to play a post nuclear game right now you could just pick up any of the fallout games (other than 76) if the unrealistic retrofuturistic elements do not chase you away, though it is a product of pindostan the americans are portrayed as pure evil to the point where the fan consensus seems to be that they had it coming and the Chinese nukes were a blessing.

    There is also a Russian game called ATOM RPG where you play as a government agent who safeguards Russia against supernatural threats, but that is turnbased game.

    I must say though your idea of defending Russia in post nuclear times has some great potential, you could have some quests where you gather forces and repair some old tanks and missiles in order to face off against some polish and ukropi nazis and some very upset cia or maybe even the japanese, you could allow some technologically inclined players to restore some ICBMs that did not launch to make an enemy faction disappear early.

    Interesting article that looks at the nature of the laser technology that is used by Peresevet.

    https://en.topwar.ru/167342-sekrety-kompleksa-peresvet-kak-ustroen-rossijskij-lazernyj-mech.html

    The author concludes by assessing that that most likely option is that Persevet is a nuclear-pumped laser where reactor energy is directly converted into laser energy (rather than the reactor generating electricity which them powers a free-electron laser). He does consider gas-dynamic or chemical lasers used on the A-60 aircraft conversion, but concludes these are much less likely, and that fibre or solid-state lasers are a non-starter.

    Interesting exerts:

    Another key subcontractor to RFYaTs-VNIIEF that can be identified from this documentation is NII NPO Luch in Podolsk (Moscow region), yet another organization belonging to Rosatom. It is responsible for an adaptive optics system needed to compensate for atmospheric turbulence that the laser beam encounters on its way to space.[19] Adaptive optics systems typically use a beacon illuminator laser that creates an artificial guide star by shining a low-power laser into the atmosphere. Light from the beam is then reflected back by components in the upper atmosphere and measured by a so-called wavefront sensor that determines atmospheric turbulence between the laser complex and the target. This information is then used to drive the adaptive optics, which consist of one or more deformable mirrors that can adjust the high-power laser beam that is subsequently aimed at the target. The use of an adaptive optics system also reduces the time that the laser needs to be maintained on the target to achieve its goal.

    The exact type of high-power laser used by Peresvet remains known. One Russian analyst recently concluded that the most likely type was a nuclear-pumped laser, among other things because of RFYaTs-VNIIEF’s close involvement in the country’s nuclear weapons program.[21] Another recent Russian article, citing only “scientific forums,” says Peresvet most likely uses an explosively pumped iodine photodissociation laser, a type of laser in which a detonator is activated to dissociate perfluoroalkalyl iodides in the gain medium and raise the resulting iodine atoms to the energy levels needed to produce a laser beam.[22] RFYaTs-VNIIEF has a long history experimenting with this type of laser and considered it for use in the Soviet-era Terra-3 laser complex, an anti-missile laser system that never reached operational status. It is also the one recommended for use in the 2013 RFYaTs-VNIIEF patent that is likely related to Peresvet. The patent holders, several of whom have a background in the development of this type of laser, claim it has a longer range than two other types that could potentially be used, namely alkali metal vapor lasers and fiber lasers. The reasons given for that are its ability to work in pulsed rather than continuous wave mode and its operating wavelength (1.315 µm, in the near infrared), which allows the beam to easily pass through the atmosphere.


    Ha ha this 'western expert' is super late. I already concluded that it was a pulsed nuclear-pumped laser nearly a full year before he did, and he looks like he cribbed/plagiarized 'findings' heavily from internet forums, but that's the level of Sovietology expertise found in the Western world. He seems to completely missed the fact that Peresvet is likely not just a Laser but highly likely a Graser and a Maser to boot. A direct beam Graser/Maser would not have any trouble frying the electronics of PGM's with high amp electrical currents, as well as completely disrupt communications between PGM's and their launch platforms. Peresvet is in fact a combination of DEW and ECM, even though the Graser/Maser aspect technically falls underneath the label of 'direct energy', it would operate more like ECM than DEW. There's also significant evidence that supports that Peresvet is a highly accurate tracker and guiding sensor for ASAT weapons against space objects.

    It'll likely share the same TEL as Topol-M's eventually, as the the current carrier of Peresvet lacks strategic mobility. The heavy MAZ Topol truck looks like it could carry more than the single reactor on Peresvet, perhaps it could hold a second reactor, perhaps 1 emitter on the front end and another on the tail end of the trailer. Imagine 2 reactors with 1-10MW output, and 2 emitters both covering 2 separate 180 degree hemisphere's of the sky.

    I would prefer they just make it look like the current in service ICBM on a truck... and rather than put two on one truck put twice the energy generation capacity so it can fire more "shots" and just make more vehicles.... the more of these driving around the harder it will be to determine where the missile vehicles are...

    The refuelling trucks that look the same could be used by the Peresvet system to extend their driving range and persistance on the road while providing more vehicle camouflage...

    Plus a couple of Boomerang based BMPT vehicles and Boomerang based 2A38 type 57mm air defence vehicles for convoy support... wheeled for better mobility with the missile/laser vehicles they protect...

    And perhaps a train based version as well with the above support vehicles and a TOR and Pantsir carriage... a peresvet at each end and a couple of nuclear scramjet powered intercontinental cruise missiles...

    I always liked the old armoured trains... I remember seeing a video from what must have been the 60s or 70s with a train with Shilkas and twin 14.5mm HMG mounts and various old tank gun turrets etc etc and it was rolling around a curved track firing an enormous amount of ordinance off to one side on a big flat open plain... awesome.

    So two Peresvets and the cruise or ballistic missile carriages and perhaps four TOR carriages evenly spaced along the train and of course BMPT turrets and 2S38 turrets providing heavy fire power and excellent target detection performance... perhaps a few airships floating around providing a clear view of the airspace and ground around the rail lines...

    Making a road mobile nuclear pumped deployed laser should be unprecedent .

    I meam , similar doesn't exist at all.

    Or you could just put that all on a giant dual ballon thing airship with gaint gauss recoilles guns inbetween the two ballons and maybe it could use its spare power for abig ion cannon in the front.

    Except they do have armoured trains... AFAIK they don't have any armoured or armed airships at the moment...



    Trains have a huge advantage in that they can work with enormously heavy loads and makes them mobile...

    Yuri Solomonov said that the 2 reasons for the Barguzin to be frozen/cancelled was 1) money 2) terrorism threat.
    So any other train system would have the same problems.

    The terrorism threat would be a much bigger factor with truck mounted missiles because those trucks don't look like anything else... the new missile systems are much smaller and look like standard train carriages.

    It really would not be that hard to develop a few rail line loops in the far east where the train is not in an actual tunnel but below ground level so only a direct hit on top would do any damage.

    It does not take a huge blast from the side to knock over a train but just the same a train in a depression where the blast would go over top could withstand a nuclear blast that is actually rather close.

    They don't need thousands of kms of brand new track for it to work... the US system was simply going to be a rectangular stretch of track a few hundred kms long and a few hundred kms wide... with lots of sidings where the train at any point could slow down and turn off the main line and sit in a siding below ground level...

    They are building lots of new tracks in the Far East anyway and if they are clever they could interweave the new tracks to improve performance of existing trains by offering alternative routes to eliminate bottle necks and congestion problems.

    Improving rail access to places like mines and gas fields is a bonus as they could all be linked to rail lines crossing Russia which links them directly to Asia and Europe as well as Russia itself, but also the northern ports to open up the area.

    Silos and naval ports are already Terrorism risks as are hydro electric dams and of course nuclear power stations...

    During times when tension is low they could be parked in some tunnel system in the Urals and the trains themselves can move freight and make money, or help distribute military equipment and food etc etc to the various new naval ports and airfields and military bases in the region too.

    As military weapons the excellent early warning system Russia has together with the way HATO and the west leaks like a sieve means they will be able to launch their missiles well before any western weapons arrive meaning in the event they accidentaly guess where they actually are they will already be empty anyway...

    Instead of ICBMs they could carry the nuclear powered cruise missiles of unlimited range... thousands of them...

    Don't know, just saying what was the reason the MoD told Solomonov, I understand your point about the truck version being different than everything else, but they have special teams, with special vehicles to protect them.
    The rail version vs truck version is more difficult to differentiate, but should be more difficult and expensive to defend from terrorism, even in peace time they would be scared all the time, Putin wouldn't sleep Very Happy
