    Space based threat
    12.08.2009

    Chief of the Air Force described the plans for Russia to "Star Wars"

    By 2030, foreign countries - and especially the United States - will be able to strike from space for the whole territory of Russia, said on Tuesday the commander of Air Force Colonel General Alexander Zelina. At the same time, he promised that by the year 2020 Russia will create a new type of armed forces in military and space defense. This year, the Air Force troops will be ready. Established teams are armed with S-400 and modified C-500.

    "Development of air-space attack foreign countries shows that up to 2030, dramatic changes occur in the development of air-space as a single sphere of armed struggle" - warned the Chief of Air Force (Air Force), the Russian Federation, Colonel General Alexander Zelenin, speaking Conference on "Status and prospects for the development of Air Force."

    "The Air Force of foreign countries, especially the United States will be able to apply a coordinated time-precision strikes on a global scale in virtually all purposes in the territory of the Russian Federation" - leads him RIA Novosti.

    At the same time, Colonel-General pledged that by the year 2020 Russia will create a new type of armed forces in military and space-defense: "The main objective of improving the Air Force Russia to 2020: the creation of a new type of armed forces is the basis of air State-space defense, capable in time of peace to deterring potential aggressors, and in the military - armed aggression reflect all the available arsenal of conventional and nuclear weapons ", - he explained.

    Zelina Alexander also reported that after 11 years of Air Force troops Russia will be ready. According to him, the task of translating the Air Force combat units in permanent readiness scheduled to perform consistently, increasing the number of permanent readiness for the period from 2009 to 2016 and the second term - until 2020, Interfax reports.

    Created teams of air and space defense systems would be armed with C-400 and C-500, said Chief of the Air Force. "C-500 is created not on the basis of P-400, the further improvement of weapons that will be capable of engaging ballistic hypersonic and objectives," - explained Zelina.

    Armament Air Force, in principle, will undergo major changes. According Zelina in Russia are under way to develop advanced vehicles, including hypersonic aircraft at a speed of approximately 6M.

    "Air Force carried out works in this field, our institutions dealing with development of a fundamentally new means and systems" - the Air Force chief cites Itar-Tass. Zelina, however, stressed that "the specific orders of such samples the latest technology the Air Force has not yet been provided, maintained until the development of a theoretical manner."

    Replying to a question, not whether or not to hurry in response to the development of hypersonic aircraft in the United States, Chief of the Air Force said: "We have to understand what level of threat from these aircraft. You should also understand what we need to stop this type of aircraft flights over the territory of Russia or friendly states. "


    Alexander Zelina said that the Russia Ministry of Defense is also developing its own unmanned aerial vehicles (UAVs), but does not preclude the purchase of foreign Designs: "Based on the concept that we presented two years ago, the Russian industry continues to create designs UAVs. At the same time not excluding the options for the purchase of foreign designs and then use them for the benefit of the Armed Forces of Russia ", - he said.

    Continuing the theme of bespilotnikov, Zelina said that in the development of domestic appliances will be used not only the experience of Russian industry, but also other countries, particularly Israel, the United States and France. And these, in his words, being well: "In particular, for the improvement of the work planned relocation center drone close to Moscow," - reminded Zelina.

    How to write newspaper opinion, less than a week ago, Alexander made Zelina and more specific statements. In particular, the announced end dates of tests and proceeds to adopt several types of technology. Thus, according to the commander, by 2020, new machines will be up to 70% of the domestic fleet of military aircraft. In doing so, up to 40% of the park will be unmanned surveillance and reconnaissance-strike complexes.

    Speaking on the future tactical aviation complex PAK FA relating to the fifth generation fighter aircraft, General Zelina stated that he entered service in 2015, but it will begin testing this. However, it should be noted that projections of a high-ranking military sometimes overly optimistic. For example, he spoke before the start of testing the fifth-generation aircraft in 2008 and entering service in 2012-m.

    Zelina on Tuesday reiterated that the Russian fifth generation fighter aircraft to rise into the air before the end of the year:

    "In November, we must fly, as a last resort - in December, but in any event, this year we will raise the car," - he has promised.

    Meanwhile, sources at the newspaper VIEW plant in Komsomolsk-on-Amur, where the assembly of multiple copies of experienced, not sure of the feasibility of these dates. The first flights PAK FA (also known under the symbol I-21 and T-50, item 059) are scheduled for the first half of 2010, probably in the second quarter. This year could be held only vykatka prototype from the factory shop.

    Head and spoke about the changes in technical and logistic BBC: "The network of repair of military aircraft will be converted to" Aircraft Holding Company with the management company within the Air Force. The storage and maintenance of air defense weapons, the supply of APP will be organized in one central database. In Each command will be formed of troop repair ", - he explained.

    Zelina said that the logistics will include general security subsystem and a subsystem for the nomenclature of the Air Force. The basis will be airborne logistic base, which, in addition to the supply of aviation and technical equipment, will provide part of the communications, chemical, engineering and motor equipment, and other materiel.

    Commenting on the issue of army aviation, head expressed his confidence that in the long run, it should enter into the composition of the Army: "The future of army aviation should be composed of the Army, but you need to create a management system to ensure that in future it was part of Ground Troops, "- said Zelina.

    2012...

    MOSCOW, August 11 (RIA Novosti) - Russia will create a new generation of air and space defenses to counter any strikes against its territory by 2020 due to a potential foreign threat, the Air Force commander said on Tuesday.

    "By 2030...foreign countries, particularly the United States, will be able to deliver coordinated high-precision strikes from air and space against any target on the whole territory of Russia," Col. Gen. Alexander Zelin said, referring to the potential for new hypersonic and space-based offensive weapons.

    "That is why the main goal of the development of the Russian Air Force until 2020 is to create a new branch of the Armed Forces, which would form the core of the country's air and space defenses to provide a reliable deterrent during peacetime, and repel any military aggression with the use of conventional and nuclear arsenals in a time of war," the general said.

    According to Zelin, all Russian Air Force units will be constantly combat-ready by 2020.

    "We are planning to conduct a gradual transition of Air Force units to a constant combat-ready status...and accomplish this task by 2020," the commander said.

    During this period, the Air Force will bring combat units to full strength, equip them with modernized and new weaponry, and significantly improve combat training of military pilots.

    Zelin said under the new concept, air-space defense brigades will be created within Russia's Air Force, and they will be equipped with advanced S-400 and planned S-500 air defense systems.

    "In line with the new air-space defense concept, we have already formed a number of brigades, which will be armed with S-400 and S-500 air defense systems," Zelin said at a news conference in Moscow.

    The S-400 Triumf (SA-21 Growler) is designed to intercept and destroy airborne targets at a distance of up to 400 kilometers (250 miles), twice the range of the U.S. MIM-104 Patriot, and 2 1/2 times that of Russia's S-300PMU-2.

    The system is also believed to be able to destroy stealth aircraft, cruise missiles and ballistic missiles, and is effective at ranges up to 3,500 kilometers (2,200 miles) and speeds up to 4.8 kilometers (3 miles) per second.

    Russia's Defense Ministry considers the delivery of S-400 air defense missile systems to the Russian Armed Forces a priority, and wants the defense industry to increase the production of these systems despite the current economic crisis.

    The fifth-generation S-500 air defense system, which is currently in the blueprint stage and is expected to be rolled out by 2012, would outperform the S-400 as well as the U.S. Patriot Advanced Capability-3 system.

    "The S-500 system is being developed under a unique design...and will be capable of destroying hypersonic and ballistic targets," the general said.

    Meanwhile, the Soviet-era MiG-31 Foxhound supersonic interceptor aircraft will most likely be used as part of the new air-space defense network, as was intended when it was designed.

    "We are upgrading this system to be able to accomplish the same [air-space defense] tasks," Zelin said.

    According to some sources, Russia has over 280 MiG-31 aircraft in active service and about 100 aircraft in reserve.

    The concept of space based weapons is just too easy, especially for both the US and Russia. The technology existed since the 60's with the earliest ICBM. Most ICBM's can leave the atmosphere and re-enter; provide one with a nuclear warhead and have it floating in space for 20 years (lack of oxygen and other forms of biological anomalies, would slow down degrading process of the warhead) and lets say at one point someone pisses someone else off, these missiles (under a command) could be re-activated and re-enter the atmosphere and strike its target. No space based defense would protect it.

    Both Russia and USA anyway operates satellites of early missile warning systems. So either or, nothing will change. But the process of these weapons that Russia is creating (former projects during the SU era) are really meant to target the communication and GPS satellites. Striking the enemies communication outpost and its position outpost, would provide the tactical advantage to the Russian's, as there would be little to communicate with both the unmanned vehicles and the soldiers out on the field.

    This is why I see moving to a high tech military (or at least the whole military) is a dangerous idea. We are better off producing high technology for abroad and export, but still provide the basic skills to the soldiers. Like a Canadian soldier friend of mine said (after he dealt with training with the US soldiers) "that is if it wasn't for their high tech gadgets, they would be useless.". I agree with him.

    Great idea, only if you plan on fighting USA. Most likely future conflicts in the following order:

    1) Georgia
    2) Ukraine
    3) Azerbaijan/Armenia conflict
    4) Central Asian terrorists
    5) Norway waters dispute
    6) Japanese over Islands
    7) China
    8} USA

    The possibility of it is so remote, we can't afford to maintain obsolete forces. We also need to mass produce high tech items so we can get export costs down, increasing our sales overseas. If we just plan on knocking out their GPS constellation, they will just put up stealth satellites making it obsolete. This is why we do not want the militarisation of space. They have already given JDAM a facelift to remove this threat. They are preparing for it so it we can't sit idle while they pass us further in technology.

    Concept of "stealth" satellites are just as much as possible to attack as anything else. Since space has less (in terms of what is close to us) objects to block out laser tracking devices, stealth satellites are more of an expensive concept with little gain. Place up satellite observing.......satellites, and there you go.

    We knock out their GPS, they lose half of their technology (if not more), and the time it would take to get more up there, is enough time for Russia to make any attack and have it done. One way or another, America is going to do what it wants in space and everywhere else. So Russia must and has to be prepared with other concepts of fighting back. Like I said, floating ICBM's in space is cheap, effective and even if in case of war, USA's ABM's are like an umbrella in a warzone. There would be no way of fighting against missiles raining from space.

    Like I said before, they will do what they want. And if they want ABM systems in space (which they will put one way or another), then mine as well give them a damn good reason to have them up there, with these missiles.

    talking about Satellites.. how's the "Polyus" project ?.. has Russians completely given up on it or maybe..want to revive it.. instead of placing ICMB on space... the Polyus can be used to to protect the ICBM en-route to target area.. intercepting the Interceptors.. i feel it's promising since the US and Japan have already began to research a "multiple Interceptors".. a concept looks similar with early Soviets "Istrebitel Satellite" by using a Sat to carry multiple small kinetic interceptor.. that will intercept the warhead along with anything its carries like Decoys.. or Jammers.

    Polus is dead as long as militarisation of space is not conducted. To intercept ICBMs were are coming out with C-500 which will be the most capable in the world.

    Polus may be dead (more then likely a storage unit), and in case of a space based threat, it can become operational. That is the wonders of Soviet technology, is that they expanded and experimented with almost every aspect of military for past,present and future. Difference is, most where prototypes. But the technology has advanced for Russia during the years (especially in the last 5 years), and these old projects (if the blue prints are still existent) can be risen from the tomb and be compatible with today's technology.

    I liked IS-MU project for hunting down enemy sats and hope that project is still alive and well.
    Concerning sats survivability I like China idea of micro sats that have ability to power on engine from now and than.

    S-300 Long Range SAM system:

    Post  Vladimir79 on Sat Apr 17, 2010 9:05 am



    16/04/2010

    It took the Kola Peninsula air-defense unit’s surface-to-air missile (SAM) systems only a few minutes to shoot down “enemy” ballistic and cruise missiles at the Ashuluk missile test range in Russia’s Astrakhan Region during military drills.  S-300 SAMs are launched against dummies during an exercise at the Ashuluk range. The Ashuluk range is 120 km by 38 km. In all, 23 missiles were launched to intercept 10 dummy rockets. Representatives from the air defense forces in Kazakhstan and Belarus watched the exercise.

    BTW little questions related to this system :

    -that S-300 appears to uses 5V55R missiles hmm vlad do you know how much G-force it can pull ? i read a PDF file sourced from dtig.org stated .. 20G.. (well it's in German) .. is this correct OR

    is that 20G is the target's G-load , so in short 5V55 can engage target maneuvering at 20G ?.

    BTW This is the pdf file

    http://www.dtig.org/docs/SA-10.pdf

    hmm hopefully your german to english translator is far better than mine Very Happy

    You need to keep in mind that these missiles travel very quickly, considerably faster than any rifle bullet.
    Also ballistic and cruise missiles generally follow a very constant path and only perform small manouvers to remain on target.
    As long as the tracking radars get an accurate fix on the target and the computers make accurate predictions as to where the target will be when the missile gets there the SAM does not need to be super manouverable.
    S-300s have a sophisticated fusing technique that means the explosion and fragments are directed toward the target, and the warhead is something like 150kgs so a near miss can still result in a kill.

    Patriot is a very good missile for bringing down aircraft, which was what it was designed for.
    For ballistic missiles it didn't have the right guidance algorithms or fusing of the warhead.
    As a result although Patriots repeatedly hit Scuds in the sense that the Patriot manouvered towards the incoming weapons and detonated their warheads because of the speed of the modified scuds it was the engine section that was shredded, which would have brought down an aircraft, but a ballistic missile is just a falling lump of metal with a warhead on the end.

    In comparison it took an average of 32 Patriots per modified scud and even then the modified scuds still generally hit with warheads intact.

    Unfair comparison?

    Not really. These S-300s are not the latest models and are the sort that would have been in Soviet service at the time the PAC-2 Patriots were in service.

    Engaging ballistic targets was always part of the design of the S-300 and S-300V series.

    The PAC-3 patriots are focussed on ballistic missiles and were not very effective against the low flying antiship missiles the Iraqis fired.

    To hit ballistic targets the PAC-3 requires a satellite channel that is not cheap.

    S-400 can hit ballistic missiles with a range of about 2,500km which means an incoming speed of about 4.8km per second.

    Small correction , the S-400 can hit target missile corresponding to a range of ~ 3,500 km ( 4.5 - 4.8 m/s )

    The Antney-2500 a derived from S-300V can hit target corresponding to a range of ~2,500 km ( 3 - 3.5 m/s )

    The A-2500 was unsucessful promoted to India as ABM system , Wiki tell me Venezuela is buying the new A-2500

    @GarryB
    Actually I believe there is currently a moratorium on putting weapons in space.

    Equally even if their wasn't the Earth is round. US air and space defences are oriented to its north, but Russian missiles could operate in the FOBS mode or fractional orbital bombardment system mode where instead of firing missiles over the north pole to attack targets in the US directly that one is fired in the opposite direction over the south pole into partial earth orbit... when it is directly over the US it can be deorbited into the upper atmosphere and detonated to generate an enormous electro magnetic pulse.
    Lots of hardened electronics will survive, but most high tech modern stuff is very vulnerable... the more high tech the more vulnerable it is... it is one of those cases where 95nm chips are better than 45nm chips.
    Another effect is that the air over the US will be ionised so radar will be useless for about 30 minutes, which is going to make tracking incoming threats impossible.

    The U.S. Defense Support Program early warning satellites, first launched in 1970, enabled the US to detect a FOBS launch.
    http://en.wikipedia.org/wiki/FOBS

    So US is able to detect incoming threat afterall!!

    an ICBM has 3 phases
    1. Boosting
    2. Mid
    3. Terminal

    Now tell me if an ICBM is launched how can US predict the trajectory of incoming ICBM ??
    My understanding is (you can prove me wrong Very Happy ) that once the ICBM is in terminal phase i.e its warheads reenter the atmosphere at a speed <<10Mach no one can predict its trajectory owing to the presence of maneuverable reentry vehicle.
    http://en.wikipedia.org/wiki/Maneuverable_reentry_vehicle

    & also one can't predict while its in boosting phase; I think while in mid-phase being in orbit makes its movement somewht known however do the US have means to pinpoint this threat even in orbital coarse!!
    Early warning Satellites as the name implies only can warn you but can't giv adequate info to intercept the coming threats (warheads). I think EWS depends on IR detection which by no means are capable to giv exact coordinates they can only ascetain whether the threat is close or far nothing else!! because unlike radars these detectors only can receive the heat signature; oneway communication not two way like in radar... dunno dunno

    What you think??

    A single launch of one rocket from Baikonur that heads south over the south pole and comes up over the continent of north america... what is the US going to do about it?

    Shoot it down with the ABM system in Alaska?

    They wont know it is a FOBs till it detonates and it doesn't have to detonate the first time around... or the 5th.

    Just put the warhead in a stable orbit and every 90 minutes you can send a signal and it will fire a retro rocket and deorbit over the US to an optimum height to create an EMP pulse that covers the entire US (except maybe Hawaii).

    My understanding is (you can prove me wrong Very Happy ) that once the ICBM is in terminal phase i.e its warheads reenter the atmosphere at a speed <<10Mach no one can predict its trajectory owing to the presence of maneuverable reentry vehicle.

    Most MARVs are designed to initiate course corrections as the warhead falls to earth to improve accuracy. The manouvers are nothing like the manouvers needed to evade an interceptor and the targets are fixed items.
    Western MARVS are designed for maximum accuracy to get as close to the target as possible and has no way of detecting incoming interceptors or being able to manouver off target to evade those interceptors and then manouver again back on target.
    The exception is of course the MARV of the TOPOL-M which has been specifically designed to perform manouvers to evade interceptors directed at intercepting it.

    & also one can't predict while its in boosting phase; I think while in mid-phase being in orbit makes its movement somewht known however do the US have means to pinpoint this threat even in orbital coarse!!

    Ballistic missiles are actually ballistic... in other words for 5-10 minutes the rockets burn, usually three stages of burn, with the first the largest, and the last normally to get the missile to the correct speed and correct trajectory to hit the target area. The third stage carries the warhead bus that releases MIRVs on targets as it flys past them.
    Because of the distance between targets after the boost phase the targets can be estimated but until the warheads are released from the bus you really don't know what the actual targets are.

    EW satellites use all sorts of methods for detection, and include IR. TOPOL-M has a high energy shorter burn rocket motor designed to minimise the amount of time during the boost phase it can be intercepted.
    During the boost phase an ICBM or SLBM is extremely vulnerable because they are emitting enormous amounts of heat and to target them you just fire a missile or projectile at the dark spot on top of the enormous plume of fire.
    In the mid course phase the warhead bus might perform some manouvers to correct its flight path, but likely it will use low power cold gas thrusters and its temperature will purely be determined by whether the sun is shining on it or if it is in shadow.

    @GarryB

    I am yet to hear from your side that what be the system that can be exploited against the warheads to giv adequate coordinates to launch an interceptor??

    If you look at the suggested ABM system in Europe it consisted of a very large X band radar to detect the incoming target and plot its trajectory and several high speed interceptors launched to reach potential intercept points at specific times.

    It requires calculations in 4 dimensions but for most targets it is not a huge problem because most targets try to keep to a strictly ballistic path and are relatively predictible.

    For terminal guidance a mix of IIR and radar are your main options and for targets that are merely correcting their path for accuracy purposes that should be fine.
    For a target actively trying to evade then it is almost impossible.

    The intercept point for a target travelling at a modest 8km per second, if it is out by 1 second you miss the target by 8kms. That is over the targets 10,000km flight, if you are out by 1 degree or one second you miss. Your interceptor rocket is travelling very fast too but it can't get to the intercept point and hover and wait, you are hitting a bullet with a bullet... hard at the best of times, near impossible if the target is manouvering specifically to evade your interceptor... and there is no reason why that incoming target wont have an active jammer or flares too.
    Above the atmosphere a decoy acts like a warhead... even when the decoy is mms thick sheet metal hollow cone... your warhead bus could carry hundreds stacked inside each other.
