    Cutting-Edge Laser Systems to be Displayed at Russia’s Military Super Show

    The military super show Russia Arms Expo 2015 (RAAE 2015) due to take place between September 9-12 has confirmed exhibition of new laser technology.

    The precision laser processing system MiniMarker 2 which will be on display during the exhibition is designed on the basis of a fiber laser with high-speed and high-quality performance, the press service of RAE-2015 said, media reports.

    MiniMarker 2 can create high-quality images, and retain a high marking speed (up to 9000 mm / s), making it capable of high-speed industrial marking of objects made of rubber, plastic, metal and ceramics.

    Apart from this particular laser system, visitors of the exhibition will also see the Foton Compact and TurboMarker systems. The first is used for laser welding and insulating chemical current sources. The second laser system has a unique record marking speed of up to 10,000 millimeters per second.

    RAE-2015 is set to be held in the Russian Urals city of Nizhny Tagil between September 9 and 12.

    The exhibition will be attended by representatives of the CIS countries, including Armenia, Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan and Tajikistan.

    Also in attendance will be delegates from a spate of European countries, such as Belgium, Britain, Hungary, Germany, Denmark, Italy, Spain, Cyprus, Poland, Slovakia, France, Finland, the Czech Republic and Sweden.

    During the exhibition, more than forty pieces of military equipment will be presented by the Russian Corporation Uralvagonzavod, which is the main organizer of the event.

    These include a spate of state-of-the-art pieces, including the T-14 Armata tank and the self-propelled Koalitsiya (Coalition)–SV howitzer.

    Russia develops directed-energy weapons

    Laser, acoustic, holographic and kinetic systems are among them, these are lasers designed not to destroy objects but to ‘blind’ them because the latter requires far less energy

    MOSCOW, September 16. /TASS/. Work in under way in Russia on directed-energy weapons, a source in Russia’s defense industry told TASS on Wednesday.

    Asked by TASS to comment on a message from the DSEi 2015 international show in London to the effect that the Royal Navy intends to adopt lasers for service by 2020, the Russian defense industry source said: "Russian engineers developing weapons reliant on new physical principles are aware of the foreign efforts in the directed-energy weapons field".

    Of the basic types of the above weapons, he singled out laser, acoustic, holographic and kinetic systems. "First off, these are lasers designed not to destroy objects but to ‘blind’ them because the latter requires far less energy," he added.

    In his words, blinding and immobilizing surface or submerged targets makes their destruction easier. However, the power plants of ships will have to be changed and their power will have to be redistributed in favor of the future weapons for directed-energy weapons to be installed on future ships.

    "Another type of advanced weapons involves kinetic weapons — electromagnetic guns that dissolve a target by means of high kinetic energy, rather than punch through it," the expert clarified.

    According to the source, acoustic weapons will be effective against surveillance systems. There are also holographic weapons, the source said without going into detail on their purpose.

    Royal Navy Adm. George Zambellas said at DSEi 2015 in London: "Energy weapons don’t require conventional ammunition. With a cost-per-shot potentially measured in pence rather than pounds, they offer a route to address the spiralling costs of missile development and production, as well as reducing supply chain demands."

    "The Royal Navy plans to demonstrate a directed energy weapon at sea by the end of the decade," Adm. Zambellas said.

    The admiral added that the British Armed Services hoped for getting weapons not just to blind the enemy or render its electronics inefficient but able to destroy fast targets, too.

    No no..it's not SF.. The DEW that use Microwave radiation is known as "HPM" Or "High Powered Microwave" Weapon. Today's pulsed power source development such as explosively pumped flux generator, supercapacitor allows generation of gigawatt level power. Add powerful microwave amplifier such as Super-reltron (Relativistic Magnetron) and it can inject that gigawatt level power to damage enemy electronics.

    One Russian example is the Ranets-E system.

    Lasers use light ("light amplification by stimulated emission of radiation")

    There are laser-like devices that use microwave radiation instead of light. They are called Masers ( "microwave amplification by stimulated emission of radiation")

    Dear PapaDragon,
    Thank you on your massage, I am very well aware of laser, how it is work, where is it is use( in 1986 I am in JNA and there we have a laser range finder to find range on armored vehicle). Now I work in for T-Com(my least employ is T-com, IT department, so I can tell that I know something about laser and it is use in every days practical use). What I do not know, is existence of maser and how it is work? I am find it like SF, so I am ask a question for it, how can be used, and what type of damage it will have introduce in targeted object. And no, it is not different particle, light and radio waves are same thing, but we can speak about lover or higher frequency of wave(light or radio waves).
    Please, do not be insulted about my post,I relay want to learn something new for my own enjoyment, for my own understanding things in the world,so, if you know something about that, please tell me. It is OK if it is on academic level Smile (after some time I will be able to understand it :L) ).
    Thanx to all
    with best regards

    The Russian government has decided to work on development of an accelerated flow carbon dioxide based laser to hit missiles and aerial equipment. The plan is to equip the latest airplanes with these laser guns. russia russia

    The latest version of the Il-76MD-90A airplane from the Ulyansk Aviastar factory will be armed with a military laser weapon. The Beriev Aircraft Company on September 14 published information on government orders on their site, saying the testing-design phase had been completed for “ergonomic provision for the development of the A-60SE airplane”.

    This indicates that research and development work on laser weapons is going ahead full steam.

    The Ministry of Defence in 2012 had announced that Russia had begun work on an aviation based laser gun to be installed on the A-60 aircraft system. The system is designed to destroy enemy airplanes, satellites and ballistic missiles.

    At Deputy Prime Minister Dmitry Rogozin’s initiative, the Foundation for Prospective Research was set up that autumn to finance the new project, which used Soviet-era advances in its R&D.

    The Soviet Union had actively worked on lasers for new types of weapons. During the Soviet period the codename A60 referred to an aviation-based laser system. It was aimed at developing countermeasures against enemy spy satellites and missiles.

    The starting point of the renewed program to develop laser weapons was the A60 special aviation system which was developed in the mid-1970s at the Beriev Aircraft Company. The Il-76MD transport airplane was the base. As part of the work, two flying laboratories were created: the 1A and 1A2.

    The А-60 was the peak of the Soviet laser program. The first flight with an onboard laser happened in 1983 and, by 1984, it had hit its first aerial target. The 1A aircraft was lost in a fire at the start of the 1990s. However, the 1A2 flying laboratory, having received specialized equipment in 2005, was named ‘Sokol Eshelon’ (Falcon-Echelon) and began flight tests again. This aircraft hit a hypothetical target in 2009 at a height of 1500 kilometers above the earth.

    The renewal and active progress of work to develop a military laser is a logical and timely step, said Alexander Kuzovlev, Associate Professor at the National Research Nuclear University (MIFI) in an interview. Laser weapons have many advantages, like practically unlimited range and high precision fire. It can be concealed and its use can surprise an enemy. Lasers, however, depend on atmospheric conditions. If there are heavy clouds, high humidity or rain, then the laser will be much less effective than in dry conditions. Also, use of a laser weapon requires advanced targeting and locking technologies on the laser itself.

    Despite the fact that Russia is intensively carrying out work in this area, it is too soon to talk about an aircraft based laser weapons system that will be accepted into service to destroy missiles and airplanes, said Kuzovlev. thumbsup thumbsup

    All this talk of lasers tends to ignore fundamental physics, such as the theoretical minimum divergence relationship, where beam spread is proportional to beam wavelength and inversely proportional to initial beam radius. I did a few calcs and found some interesting results:

    For an IR laser with wavelength = 808 nm and a beam diameter of 10 cm, the divergence is 10.3 mm/km. Firing a beam at a target 200km distance, the beam at target will be 216 cm across, and the effective power density will drop by factor of 466. Increase the initial beam diameter to 100 cm and the divergence drops to 1.03 mm/km, beam at target is 121 cm across, and power dilution factor is only 1.45.

    These are theoretical minimums, so in practice the actual beam divergence will be greater, and atmospheric effects causing beam scattering or absorption will result in further losses.

    I tried punching in publically available data for the 80s era MIRACL from the US (~14cm beam diameter, 3.8 micron deuterium fluoride IR laser) and its performance looks un-inspiring. In the above scenario, beam divergence is a whopping 34.6 mm/km, beam diameter at target is no better than 7.06 meters and power dilution factor is 2540. Against a 0.5 m2 target and at full power (1MW for 70 secs) MIRACL could focus no more than 12kW (and in practise it would be very much less once atmospheric losses are taken into account). While this could result in damage to an aircraft (if the targetting system could manage to hold the beam in place against defensive maneuvers) it would be next to useless against ballistic missile warheads (which are equipped with heavy ablative shielding to protect against the heat generated from atmospheric re-entry).

    Anyhows, this isn't meant as a comprehensive assessment, but puts a few figures up for indicative purposes.

    Is this an "EM weapon"??

    Russia’s Rostec Corporation is to unveil a super-high frequency weapon capable of taking down all kinds of drones, missiles and other high precision weapons. The presentation will be made at the Army-2015 military expo.

    The Mosow Radio Engineering Institute has developed a super-high frequency (SHF) ‘cannon’. It’s designed to knock out aircraft, drones, guided missiles and any airborne high precision weapons using electronics.

    The cannon creates an air-exclusion zone within a reported radius of over 10 kilometers around the defended object or installation, though the system’s exact characteristics are classified.

    Not at the moment. Airborne laser weapons suffer from four major handicaps:

    1) Stability. To achieve burn-through of the target, the laser needs to shine continuously at the same point. Assuming it is firing at a 'dumb' target such as a drone or missile, air turbulence will make the firing platform quiver constantly in three dimensions making pinpoint targeting very tough, assuming the beam projector has exceptionally precise (and rapid skewing) tracking.  A piloted plane would probably go into evasive manoeuvres as soon as it detected the laser beam, making burn-through far more difficult.

    2) Air quality. Water vapour significantly atrophies the energy in a laser beam. Whilst high altitude flight above 10k metres is relatively clear of pollutants and vapour, all it would do is push the theatre of operations (at least during the approach phase) back below or within cloud level.

    3) Range of engagement. A laser whilst capable of heating/cutting at short distances, cannot hope to match the reach of a long or even medium range missile. Even clear air still atrophies beam energy and collimation spreads quickly over range.

    4) Heat dissipation. Lasers are very inefficient energy-wise. Most of the power supplied to a laser system ends up as waste heat. Now aboard a naval vessel, you can dump this excess heat straight into the sea as water is an excellent heat sink. A plane however can only rely on air flow which is far worse at absorbing heat, especially at high altitudes where the atmosphere is thinner. Also bear in mind that modern fighter jets are already straining their cooling systems just running their radars.

    Those are the main difficulties. Others are the need to integrate a lot of heavy capacitors from which the energy for the laser pulse is stored, additional electrical generation from the engines guzzling fuel, partial mirroring if wavelength of the laser is known plus ablative layers which can 'foul' the beam before contact, speeding up AAM missiles to reduce closing time, the limited power output of the weapon due to poor energy generation of the hosting airframe, and so on.

    All in all they are not really a threat when mounted on planes, at least not against other planes. Possibly against AAM until designers incorporate laser detection and in-flight jinking/spinning to increase its lifespan to reach its target, or if the laser is only intended to burn out optical sensors. Even then, a simple aerial tactic might be to simply fire off two missiles to swamp the laser defence.

    Laser systems aboard ships are a different matter, as vessels have far greater power generation, greater firing stability and easy access to water cooling.

    It only get worse if you try to use lasers to kill incoming hypersonic weapons. A missile flying at mach 6-7 at low altitudes is going to require some serious thermal shielding to cope with heating from air friction, and that shielding will further degrade a lasers performance by increasing the energy needed to achieve a burn-thru. More energy required + shorter time available for engagement + tracking difficulties = an inefficient system to defeat hypersonics

    Russian ground based lasers destroy U.S Satellite.

    Satellite explodes :response to debaltseve crisis



    satellite explodes : response to Turkish fighter jet incident

    It took less than 10 hours after the SU-24 was brought down by Turkish jet to track and destroy this satellite.

    Russians do have ground based ASAT lasers . We dont know what kind of lasers destroyed this satellites. Surely the targeting and the destruction of satellite was done by Russian ASAT lasers.
    The second satellite a less powerful laser pulse was used because indications are this laser attack generated less debrie in the orbit. A more sophisticated laser
    for that matter.

    I remember there was a famous video in the 80s or 90s showing a rocket booster being destroyed by a laser... and it was quite impressive until you actually looked properly at what was happening.

    Basically the booster tube was pressure filled with air to simulate it being full of fuel and there were large I beams of steel on top of it held in place with steel cables.

    the laser... which was up very close and concentrated on one point of the booster for some time eventually popped the outer surface and with a large blast of the interior gas escaping the heavy I beams crushed the booster with wire cables flying everywhere... very impressive but a poor example of an effective laser weapon.

    For one thing the Soviets could easily add a small amount of spin to their rockets so the laser will not be able to concentrate on one point for long enough to penetrate through.

    Secondly... and most importantly... to hit a solid or liquid filled booster you need to have your laser right next to the launch site... with incoming warheads the only target is the warhead... which will be covered in an ablative material that resists heat. Ie you are trying to penetrate a heat shield with a weapon that defeats its target with heat.... I call that pissing on your own shoes.

    The Russians are much more sensible and have said publicly that their current experiments are focussed on defeating EO systems on recon aircraft (manned and unmanned) and also on satellites... a much more sensible and practical goal IMHO.

    eventually they will be powerful and effective and cheap enough to use to shoot down aircraft but for the present Missiles already do that effectively enough.

    Invest in them, but don't expect miracles.

    BTW this talk of destroying satellites with lasers is amusing... a laser will concentrate energy on one point on a satellite and can do damage but to actually blow a satellite to bits reminds me how every car in a hollywood movie bursts into a huge fireball when shot... at least in a car there is a tank full of petrol... in a satellite there will be batteries and solar panels... ie nothing that will blow the entire platform into small pieces when hit with lots of heat.

    A laser can be used to disable a satellite and even damage sensors to make them ineffective, but to blow it to bits is just BS.

    Basically the booster tube was pressure filled with air to simulate it being full of fuel and there were large I beams of steel on top of it held in place with steel cables.

    the laser... which was up very close and concentrated on one point of the booster for some time eventually popped the outer surface and with a large blast of the interior gas escaping the heavy I beams crushed the booster with wire cables flying everywhere... very impressive but a poor example of an effective laser weapon.

    You can still do that. Satellites contain propellant for manuvering and if you hit the tank... you know what. Or even Batteries... depending on the battery type, its chemistry can do a lot of damage...

    Most of the propulsion is compressed gas... it could be nitrogen, which is totally inert... so even if hit directly there wont be an explosion... just an energetic venting of gas.

    A battery contains volatile materials but at worst you will only again get a blast of material like a jet and any fire would die down rapidly in space.

    To make it explode it needs a very large charge of HE of some type... something they would not bother with as it would seriously reduce the performance of the satellite having a lot of dead weight on board.

    Well batteries are comparativelly big and heavy on satellites. Because of the temperature i guess a lead acid or some similar chemistry is used in order to store as much charge as possible having very low ambient temperature. Then there is the problem of radiation - which you have to take into account. It could have happened that a direct hit to a battery caused a large chunk of the satellite body to rip of but total disintegration - i would say journalists have exagerated that. Nonetheless it disabled the target quite effectivelly.

    Laser weapons

    Batteries really don't like cold temperatures... batteries of all types would not take the cold of space for long without serious insulation and heating systems... which suggests to me good protection from a laser...

    I would agree the journalists exaggerated... that is what they do sadly.

    In Russia, plans to launch the most powerful laser system in the world

    MOSCOW, May 30 -. RIA Novosti The first stage of world's most powerful laser system UV-2M launch in Sarov (Nizhniy Novgorod region) in late 2017, told the director of the Russian Federal Nuclear Center - All-Russian Research Institute of Experimental Physics (Sarov) Valentin Kostjukov the forum "Atomexpo 2016".

    According Kostyukova, 95% in Russian laser system technology will be used.

    Laser installation of a new generation of intended for fundamental research in the field of high energy density physics, including - the use of laser fusion in the energy sector. UFL-2M will have a dual purpose, one of which - the war. Experiments in Physics hot dense plasma and high energy density, which take place on this type of installations, can be directed to the creation of thermonuclear weapons. The second direction - energy. Laser fusion can be used for the development of future energy.

    At one of the meetings of the Scientific and Technical Council of the nuclear weapons complex "Rosatom" developers installation noted that the creation of UFL-2M is important for in new energy research, the study of states of matter, experiments for the simulation and design of new types of nuclear weapons.

    Developments taking place in the field of Electromagnetic rail guns in Russia

    Post  moskit on Mon May 30, 2016 5:14 pm

    Long live Russia,

    Dear admins,

    There are lot of fuss about the electromagnetic rail gun that the US developed and tested recently in media. It says sing its truly a game changing weapon and few analogues are there to challenge it> I would like to know how the Russians have done with that technology and what are there achievements in this field. Thank u,
