    If we are going to consider the notion of some air breathing engine then there are too few intakes. Mach 10 can be achieved with
    solid rocket propellant. It appears that Russia has pushed the chemistry to higher limits for this fuel.

    Hey, with England being a bunch of bitches and threatening Russia, maybe we will be lucky to see this missile sink a UK carrier.

    If it has a range of 2,000km then it cannot be rocket powered and with a speed of mach 10 then it can only be scramjet powered because a solid rocket motor would not carry it 2,000km and a ramjet is not able to operate at such high speeds.

    Seeing as how from this we can assume it is a scramjet it is fairly obvious that intakes are obviously covered or retracted and uncover or deploy when the solid rocket booster has burned out.

    Yeah... have a parade in London where it is actually raining bits of May... a May parade... or more formally a Theresa May parade... or should that be cascade... or perhaps waterfall... the commies will love it because it will be red...  Twisted Evil

    Well if evil putin is going to murder two nobodies and Russia is going to suffer under sanctions because of it why not take down a head of state and go for some good old fashioned red blooded American regime change... I would say a percentage of the british population would appreciate it actually... who is bringing the beer...

    1) You assume a constant burn.

    2) 2000 km translates to 10 minutes of total flight time at Mach 10.

    3) Nobody said Mach 10 was the peak speed. In fact, it sounded like a reference to "effective speed". So it could
    easily be a two stage rocket design (but with one body instead of two sections). A rapid Mach 15 initial burn followed
    by a gradual momentum maintenance burn to prevent air drag from reducing range too much. So this thing likely takes
    less than 10 minutes to traverse 2000 km.

    4) Those tiny intakes would be producing vacuum cavities in a scramjet. Seriously, it is laughable to claim
    that those intakes are sufficient for a scram jet. Not a single ramjet or scramjet diagram shows a tiny inflow
    aperture. In fact it looks like a ram scoop, i.e. the intake area is large compared to the compression zone.

    Russia picks MiG-31 fighter as a carrier for cutting-edge hypersonic weapon

    TASS highlights the history of creation and the unique potential integrated into the Russian fighter-interceptor, and also the capabilities of the Kh-47M2 invincible missile


    In March 2018, the world learnt that Russia possessed the Kinzhal (Dragger) unique airborne hyper-sonic missile system designed to destroy ground and sea targets. The MiG-31 supersonic long-range all-weather fighter jet developed by the MiG Design Bureau during the Soviet period and accepted for service in 1981 was chosen as a carrier for the new missile system.

    The MiG-31 or the Foxhound as it is called in the West is a veteran of Russia’s Aerospace Force but is still unique by its speed and altitude capabilities.

    The fighter jet can easily climb to an altitude of 25 km and accelerate to 3,000 km/h, after which the missile that reaches the point of its discharge within minutes starts its autonomous flight. Nuclear and conventional munitions are delivered to the target to a distance of up to 2,000 km. Moreover, the missile can deal a serious blow on the enemy without entering its heavily protected air and anti-ballistic missile defense system.

    Thanks to the MiG-31’s high performance characteristics, the hypersonic missile with low radar signature and highly maneuverable capabilities of the Kinzhal system (the Kh-47M2 missile as some open sources report) has no rivals in the world.

    Kinzhal’s invulnerability

    In a video shown by the Russian president on March 1, a MiG-31BM plane delivered a missile to a point of its discharge, following which it flew at hypersonic speed (at more than 10 times the speed of the sound) and maneuvered at all the sections of its flight path. In the opinion of Russian Deputy Defense Minister Yuri Borisov, the basic specific task and complexity was to ensure that the missile could reach hypersonic speeds, i.e. about 10 Mach.

    “This allows approaching a target quite quickly as compared, for example, to cruise missiles that fly at an average cruising speed of around 850-900 km/h, i.e. the primary specificity is speed, in the first place,” the deputy defense minister said.

    As the second specific feature, it is capable of maneuvering during its flight with the help of aerodynamic control and bypassing air defense or anti-ballistic missile defense zones, Borisov said.

    Yuri Borisov, Deputy Defense Minister of Russia wrote:The anti-missile shield becomes pregnable in this situation. Precisely the ability to maneuver in a hypersonic flight makes this weapon invulnerable and makes it guaranteed that it hits the target

    As Commander-in-Chief of Russia’s Aerospace Force Colonel-General Sergei Surovikin said, the creation of the Kinzhal system marked an important breakthrough in the development of hypersonic weapons. A carrier aircraft delivers an aero-ballistic missile to the area of its discharge within just minutes, after which the main propulsion unit accelerates the munition to hypersonic speed within seconds. “At the final section of the flight path, a homing warhead is activated to ensure the required accuracy and selectivity of target engagement in any time of day or night,” the commander-in-chief said.

    The flight to the target also takes several seconds, which excludes the missile’s interception by air defense capabilities. The Kinzhal’s efficiency has been numerously proven during state trials.

    From December 2017, the first aviation unit in Russia’s Southern Military District armed with the Kinzhal hypersonic missile system went on experimental and combat duty to test the fundamentals of the system’s combat use.

    “This is far from being fantastic,” Deputy Defense Minister Borisov says.

    “Moreover, this is a class of precision weapons fitted with multifunctional combat capabilities making it possible to strike both stationary and mobile targets. Specifically, aircraft carriers and cruiser-class warships, destroyers and frigates are potential targets for this weapon,” the defense official said.

    In the opinion of TASS military expert Viktor Litovkin, the deployment of MiG-31 fighters carrying the Kinzhal hypersonic missile systems in the Southern Military District can be most likely explained by the need “to keep under control the Black Sea area,” which US and NATO warships armed with Tomahawk long-range cruise missiles regularly enter, posing a threat to strategic missile systems in Russia’s European part.

    “The Kinzhal system is precisely intended for their deterrence. Intruders must know about this,” the expert said.

    Incidentally, the crews of Kinzhal airborne hypersonic missile systems in the Southern Military District have already performed about 250 flights day and night in various weather conditions since the beginning of 2018, according to the reports by Russia’s Defense Ministry.

    Viktor Litovkin, TASS military expert wrote:Besides, close to the Black Sea area is Syria where we have our interests, the eastern coast of the Mediterranean Sea, as well as the Hmeymim and Tartus military bases. It is not ruled out that the Kinzhal may also come in useful in this region, all the more so as the distance from the Krasnodar Region to Syria is not very large. It takes half an hour flight by a MiG-31 fighter jet


    On March 11, Russia’s Defense Ministry posted new footage of the Kh-47M2 hypersonic missile’s trials. The video shows a MiG-31 fighter jet without external hardpoints for R-33 air-to-air missiles making part of the fighter’s organic armament. A new external sling has been specially developed for the Kh-47M2, which suggests the weapon’s big weight. As military experts presume, the fighter jet may get a new modification in the future, for example, the MiG-31K. It should be noted that initially the aircraft was an interceptor rather than a carrier of air-to-surface weapons.
    Viktor Litovkin, TASS military expert wrote:
    I believe that the strategic Tu-22M3 long-range aircraft will also be upgraded in a perspective as Kinzhal carriers. They are supersonic and can also take on a large load of munitions (12 tonnes), including the Kinzhal. The only thing to be done is to make structural changes in the aircraft

    The data of open sources suggest that the Kinzhal is a distant prototype of the Soviet Kh-15 tactical attack missile accepted for service in 1988. At the same time, the Kinzhal’s external outlook has similarity with the 9M723-1 aero-ballistic missile (NATO reporting name: SS-26) of the Iskander-M missile system. It has a flight speed of up to 1,800 m/s and an operating range of 400 km. Most likely, the Kinzhal’s first stage was developed on the basis of the Iskander missile system. The missile’s front part shown in the video was blurred.

    The Kh-15 hypersonic missile with the thermonuclear warhead was regarded as a Soviet response to the US SRAM missile that went into service in the US Air Force in 1972. The Kh-15 was intended for arming Tu-22M, Tu-95MS and Tu-160 strategic long-range bombers. However, before the disintegration of the USSR, only several regiments of Tu-22M3 long-range bombers had the time to learn to operate the new missile. The mass production was impeded by economic problems and the range unsatisfactory for the military as it did not allow operating outside the area of enemy air defenses. When launched from a bomber, the Kh-15 could climb to an altitude of over 40 km and then dive at the target following the trajectory close to the ballistic flight path and developing a speed of Mach 5.

    Russia started to gradually phase out the Kh-15 missile in the early 2000s owing to the termination of its serial production and the expiry of the warranty period of keeping solid-propellant components. It is known that it was used as the basis to develop missiles with conventional warheads – the Kh-15P anti-radar missile and the Kh-15S anti-ship missile. Su-27 fighter jets could be among carriers for the latter missile; however, there are no data on its acceptance for service.

    Despite such similarity in design, the Kinzhal’s performance characteristics are by a factor higher than the parameters of the 9M723-1 and the Kh-15.

    Kinzhal missile fly up to mach 10 speed.

    So lets see how fast is this..

    it covers

    3.43 kilometer  in 1 second..  Shocked

    205.8 kilometers  in 1 minute..

    and the most probable combats will happen from 100km to 300km.

    So this means ,that a mig 31 flying very high ,could strike and aircraft carrier group
    with a nuclear armed missile in just 30 seconds.. if fire them withing 100km distance.
    This is an incredibly low time , that NATO will have to counter the missile..
    and if it is true? that Russia plasma stealth that the missile have ,works as good as their animation videos..
    Then NATO will not even be aware of the missile at all being fired ,and will only detect the missile through
    infrared sensors ,only when is 5 to 10 seconds the missile from impact.. So it will be a total wipe of the battle group.
    All battle group wiped.. in just 30 seconds.. forcing NATO to completely change their defense positions big time..
    and stay farther from Russia land.. and to spread their naval forces even further ,allowing submarines to more
    easily sneak inside their battle groups.

    For me the ultimate deterrence will be a Mesosphere stealth killer carrier bomber with plasma stealth tech... to bypass NATO radars.. This will allow Russia to position their bombers right on top NATO battle groups. and undetected.
    and position their bombers very close strike distance ,that is just 50km away.. and in just 15 seconds.. sink an
    aircraft carrier with domestic bomb or the entire battle group with a small nuclear blast.. and wipe their radars and
    totally damage the electronics..  disabling the battle group and making it very easy to sink them..

    So if NATO build Aircraft carriers.. Russia should counter it..with long range mesosphere bombers ,armed with
    hypersonic kinzhal missile.. So if NATO deploy 12 aircraft carrier , then Russia counter it by deploying 12 mesosphere
    bombers armed with conventional and nuclear armed kinzhal missiles.. That way .. in case the unthinkable happen..
    and Russia realize NATO is preparing to strike Russia , then Russia can give the order of complete defeat of US navy aircarriers groups.. and by making the bombers nuclear engine... they can stay weeks or months in air..

    This also could be used to decapitate the leadership of any government in the world.. a surprise attack and boom..
    in just 1minute to 3minutes.. wipe the government of any hostile nation without warning.. and provoke a civil war
    for the lack of government.

    So what could be better than a Kinzhal missile for strategic war ?
    Than building an aircraft ,that will allow the missile to be deployed very close to the enemy ,withing visual distance
    of the target..while remaining hidden of the enemy.. and strike in a matter of 15 to 30 seconds.  it will be a one side fight.

    What is important to remember ,that very few people realize.. is there are elite forces in NATO that will consider
    acceptable  and nuclear war with Russia , even at the cost of millions of civilians if in the end they can quickly defeat Russia ,by a surprise massive attack. from close to Russian borders. it was Putin who told recently NATO is deploying
    no less than 60 warships + submarines in "training exercises" withing dozens of kilometers of Russia borders in Norway coast..  What they are doing in testing strategy for a nuclear first strike massive attack. that they will not do it for fear of Russia retaliation is not necessarily true.. because all  this elite billionaires who controls US and UK policies have properties all around the world..The later saying is that they building properties in new zealand to have a chance to survive a nuclear war between US and Russia.

    NATO exercises in baltics also train for an invasion of Russia in a zone totally nuked and full of radioactivity..
    That is Preventive nuclear massive strike ,followed by a full scale NATO invasion .. What all this means..
    is that people cannot use traditional logic , in understanding NATO strategy with Russia.. Since many crazy generals
    will not mind a nuclear war .,if they can strike first and significantly reduce Russia capabilities to do a full nuclear strike.


    This is why Russia needs an strategy to bring down very fast NATO navies.. in case of a nuclear war..because
    even if Russia manage to nuke all United States, the US navies ,NATO navies will be untouched..and still combat capable. and can reorganize the American government in Europe or other secret parts of the world.

    So forget about Pak-fa .. or any other plane..
    The real serious major leagues deterrence for Russia that could develop is a
    1)Mesosphere stealth Bomber that carry several Kinzhal missiles.
    2)A Mig 41 , that is also stealth and carry Kinzhal missiles too.

    NATO strategy is control of all the seas. and this is not coincidence.. this is a strategy of long term war..
    knowing that it will not be won by nukes.. but if you control the sea routes and destroy a nation economy
    that you can force them to surrender.

    So Russia can answer and totally blow away ,NATO navies with just a dozen of Mesosphere bombers and
    enough MIg-41..armed with hypersonic missile to dominate lower earth space.. Who totally dominate space will have the power to totally control anything under it..,also block space access, can also control satellites . this will be really humiliating and force NATO to the negotiation table. If NATO wants to controls the seas.. Russia can counter that more efficiently
    by their airforce creating space superiority. and enforcing a No Space zone..  Cool

    1) You assume a constant burn.

    I clearly stated:
    Seeing as how from this we can assume it is a scramjet it is fairly obvious that intakes are obviously covered or retracted and uncover or deploy when the solid rocket booster has burned out.

    How could it possibly have a constant "burn" if it has a solid rocket booster and then a scramjet motor?

    3) Nobody said Mach 10 was the peak speed. In fact, it sounded like a reference to "effective speed". So it could
    easily be a two stage rocket design (but with one body instead of two sections). A rapid Mach 15 initial burn followed
    by a gradual momentum maintenance burn to prevent air drag from reducing range too much. So this thing likely takes
    less than 10 minutes to traverse 2000 km.

    When described as being a Mach 10 missile that is generally peak top speed...

    There is no chance of a mach 15 initial "burn"... most modern rockets run at between mach 4.5 (for the Kh-32) and about mach 7 for the 400km range Iskander ground launched missile.

    Obviously if launched from 25km altitude and at mach 2.5 then performance would be increased, but most likely the solid rocket booster for this missile will be minimised because it clearly has an operating scramjet motor and a scramjet motor has higher speed potential than solid or liquid fuelled rockets.

    4) Those tiny intakes would be producing vacuum cavities in a scramjet. Seriously, it is laughable to claim
    that those intakes are sufficient for a scram jet. Not a single ramjet or scramjet diagram shows a tiny inflow
    aperture. In fact it looks like a ram scoop, i.e. the intake area is large compared to the compression zone.

    What tiny intakes?

    For all we know the nose tip might be jettisoned and the air intake is the open nose area...

    As technology improves scramjets will only get more efficient and scramjet powered missiles will only get faster... the only top speed limit for a scramjet propelled aircraft is its ability to endure heat... the engine and the aircraft structure.

    The radar is in the nose.

    Small intakes. Remember the speed ot that thing. Even in the thin air in which the missile flies and with a few small intakes there will be enough air collected to Keep the scramjet runnig.

    And the metal around those small intakes would burn off. No diagram of a scramjet or ramjet has ever shown the intake
    aperture to be smaller in area than the compression zone of the engine. It is straightforward fluid mechanics. Large speed
    does not invalidate physical laws: the engine is taking dilute air and compressing it to get effective combustion. We are not
    talking about movement in a liquid medium (which is essentially incompressible).

    Small intakes work for the Kh-31.

    We don't know its propulsion. Iskander is hyperosnic too only because it goes very high out of the dense atmosphere so it can reach high speed. For Kinzhal it could could be the same but with a far better manoeuvrability.

    If it reaches a speed of mach 10 and goes back in the atmosphere to attack a ship, it will only spend some seconds inside the atmosphere so it doesn't need a propulsion for 5 or 10 seconds. It will probably decelerate but it doesn't really matter.

    Actually, a deceleration or an acceleration makes the impact calculation for a potential air defence system harder. If the missile goes at the same speed all way it's easy to calculate an impact point. But if your missile is able to accelerate and decelerate randomly it would improve its penetration capability. For subsonic missiles it won't be helpfull but if you try to intercept a missile flying at mach 10 but then it slows down to mach 7 your interceptor missile will miss by tens of km if not hundreds and will be in front of the missile ith no more chances to hit the missile. Then you lunch another one to intercept the now mach 7 missile but it accelerates to mach 10 so your missile will be far behind the missile.

    If you manage somehow to know when the air defence system lunches its missiles and control your Kinzhal then this tactic would work at 100%.

    I'll add my 2 cents worth.... Very Happy

    The so-called "intakes" on Khinzal have not IMHO been shown in sufficient detail to confirm if they are actual entries into the missile body, or if they are, how far they penetrate.  They look too small to be useful intakes, and have the general appearance of dielectric panels that you'd typically see over antennas in ELINT aircraft, so I wonder if they are actually sensors of some kind?  Alternatively, they could be the outlet ports of waveguides for a plasma-stealth generator?  Don't laugh or dismiss this out of hand as we know that plasma from hypersonically-induced friction is perfectly capable of blocking EM radiation.  The theory would be that the missile body is screened with plasma to reduce RCS, while the nose is left unscreened so that targeting sensors remain operable.

    If so, that suggests that the Khinzal isn't fitted with scram-jet engine (unless there is some unseen intake that is either deployable, or concealed behind an ejectable panel and revealed after the SRB burn-out) and cruises at high altitude at M4-5 and relies on dive from high altitude to build its terminal-attack, maybe with a final kick-stage motor to boost to M10?

    Where are these people getting their notion that these are air intakes for an engine from? Have they seen any other air breathing engines
    in aerospace with tiny square intakes? Seriously, what is this crap?

    Since the range and speed of this missile imply that its flight time is 10 minutes or less, solid rocket propulsion is sufficient and consistent
    with its external appearance. Solid rocket propulsion would also be rather reliable.

    A two stage solid propulsion system seems to be the design. A slower burning fuel formula for stage 1 and a fast burning formula for stage 2.
    I think Russia has developed new types of solid rocket fuel that the USSR could only dream of.

    Since the range and speed of this missile imply that its flight time is 10 minutes or less, solid rocket propulsion is sufficient and consistent
    with its external appearance. Solid rocket propulsion would also be rather reliable.

    Sorry dude but that is just crazy... the missile is about the size of the Iskander, which has a range of about 500km at about a peak speed of mach 7... and what rocket motor burns for ten minutes?

    Rockets going into space burn for less time than that...

    The weapon is hypersonic so it would have to be a scramjet... meaning supersonic combustion... on a jet airplane its air intakes open fully on take off because at low flight speed it needs to maximise the volume of air entering the engine to maximise thrust. When flying at altitude however the problem is too much air entering the engine and choking it... so the air intakes close down to reduce the amount of air entering the engine so it is not supersonic when it goes through the engine.

    This rocket will be launched from high altitude likely already moving at more than mach 2.. the solid rocket motor is likely just there because a scramjet engine has a big empty space at its rear... so you might as well fill it with a solid rocket motor and get a bit of extra speed and height before the scramjet motor is started.

    Once running the scramjet can run at pretty much any speed because it can burn fuel at an speed... supersonic or subsonic.

    As I said normal jet engines choke on supersonic air so normally when flying at supersonic speeds the air intakes are reduced down to reduce the amount of supersonic air entering the engine... when it gets past the intake ramp there is a much larger volume of space so it slows down before entering the engine and getting fuel added and burned...

    The F-16 could easily fly faster than Mach 2 but it cannot because it has a fixed air intake so it chokes on supersonic air at above mach 2.

    In comparison the MiG-29 and Su-27 can fly faster... generally about mach 2.3-2.5 for very short periods when needed because they have heavier, more complicated variable air intake ramps.

    Have they seen any other air breathing engines
    in aerospace with tiny square intakes?

    Actually all the photos of models for hypersonic aircraft have small chin mounted square intakes.

    Russia tested a scramjet engine in the 1990s on the nose of an SA-5 SAM and it used a round intake.... the important thing they took from that test was that a simpler square intake would be easier to model and control.

    This little things with red covers could be windows for the fuze.

    It is a scramjet. Propably the intake is under the belly, a hinged lid that opens downwards and forms a ramp for the airflow.

    Because it does not need to slow down the airflow the intakes don't need to be very big... it could have scoops that open up if needed... the faster the air goes into the engine the more thrust the engine will generate....

    10 MiG-31 with Kinzhal missiles are already on experimental combat duty

    This missile can maneuver only in the terminal phase. It's just a ballistic missile.

    What do you know about it ? You worked on it ?

    Manoeuvring at mach 10 means if you change your direction of 1° while an interceptor missile is trying to intercept you will result in the point of interception being moved by some tens of km which means the interceptor missile won't be able to destroy the missile.

    When they say manoeuvring it is this sort of manoeuvres they talk about not cobra or kubilt manoeuvres. And for that you only need an engine to start for 1 or two second every time you change the direction.

    This is typical ballistic missile. Ballistic missiles or RV maneuvers only in the atmosphere in terminal phase.

    Iskander is a ballistic missile and has a far slower speed which confirms that kinzhal is not a BM because it flies lower than BM but with a greater speed.
