    Then Russia should also deny selling the system to Turkey, given they are a NATO country.
    Their concern is related to the friendly attitude of Turkey towards Russia or against the S-400 exactly? Your point would mean that Turkey is not a trustworthy ally.

    Yes currently, they clearly don’t seem as trustworthy as Israel or UK or Japan..etc
    The buying of S-400 could mean a start of friendly relation between Turkey and Russia

    they are perfectly ok with them buying Patriots and the rest of the hi-tech catalog, as far as they don’t buy the S-400. So the problem is the weapon itself it seems. A system they were also bitching about in regards of India, even when they buy countless other weapons systems from Russia.

    Patriot isn’t Russian made, so obviously it won’t help strengthen the bond between Russia and Turkey. Besides, Russia was also bitching when US put missile defense system around Europe, it kinda common practice for both sides to limit the influence of their rival.

    To me modern Russian SAM systems are perceived as a threat of first order to the Western interventionism and hence both fought by US and sought after by countries that feel threatened. But we can pretend all is normal regarding US reactions to this system

    It is a normal reaction, you just prefer to think otherwise
    It is not like Russia have a different reaction when the situation is reverted

    MOSCOW — As American and allied officials celebrated the opening of a long-awaited missile defense system in Europe with a ribbon cutting and a band, the reaction in Russia on Thursday suggested the system had raised the risks of a nuclear war.

    Russian officials reiterated their position that the American-built system imperiled Russia’s security. But the public discussion in Russia was darker, including online commentary of how a nuclear confrontation might play out in Europe, and the prospect that Romania, the system’s host, might be reduced to “smoking ruins.”

    “We have been saying right from when this story started that our experts are convinced that the deployment of the ABM system poses a certain threat to the Russian Federation,” the Kremlin spokesman, Dmitri S. Peskov, told reporters in a conference call.

    “Measures are being taken to ensure the necessary level of security for Russia,” he said. “The president himself, let me remind you, has repeatedly asked who the system will work against.”

    The United States has asserted that the anti-ballistic missile system would protect only against “rogue” states, particularly Iran, and provide no protection for either Europe or the United States from Russia’s far larger arsenal of nuclear missiles.

    Russia Warns Czech Republic, Poland On Missile Defense
    Russian Foreign Minister Sergei Lavrov today reiterated Moscow’s concerns.
    “We are seriously concerned about plans to deploy elements of a U.S. missile-defense system in Europe and the critical situation that threatens the Conventional Armed Forces in Europe Treaty,” Lavrov said.
    “NATO’s enlargement, which is undertaken despite the assurances we were given previously, does not help strengthen trust either. We are also concerned about the advance of the alliance’s infrastructure toward the Russian border.”
    Nikolai Solovtsov, the commander of Russia’s Strategic Missile Forces, said on February 19 that Russia may withdraw from a 1987 treaty with the United States limiting short- and medium-range missiles in Europe if the U.S. plan goes ahead.
    Solovtsov also warned that hosting the U.S. shield could make the Czech Republic and Poland targets of a Russian missile strike.

    Russia cries foul as Nato activates missile defences in Europe
    Tensions between Russia and the West rose still further on Thursday when Nato declared that a missile defence site in Romania had become operational.

    A battery of American SM-3 interceptors, designed to shoot down incoming missiles, was activated at Deveselu military base. A similar facility is due to become operational in Poland in 2018.

    Only a handful of interceptors will be deployed at the two bases, enough to protect Europe against attack from a country possessing a small arsenal of nuclear missiles. The missile shield would be of minimal use against Russia, which has about 300 inter-continental ballistic missiles on land and scores more deployed on submarines.

    Nonetheless, Russia claims to sees the missile defence plan as direct threat to the deterrent power of its own nuclear arsenal.

    [QUOTE=”panzerfeist1] I got some very good source information your going to like that I can proudly say this will be my last post regarding this topic.
    I found a very good answer for this and I am sure you will be surprised.
    PG6
    But it seems that pg 7 has the solution to this problem you mentioned.[/QUOTE]
    Yes, that a very good source, far better than internet tabloid
    But looking into the study, they clearly mentioned that you need a large amount of scatters distributed along the beam path to achieve this resolution, seem too convenient ? besides a resolution cell of 80 meters in optimum condition is still far larger than the physical size of any fighters

    [QUOTE=”panzerfeist1]I am assuming anything below that 500 nautical miles you have said is a blind spot and cant be covered correct? I realized there was a 60 degree limit for some OTH radars meaning you can not get a 70, 80 or 89 degree coverage to get that blindspot covered but there is something that I believe we have both missed(although it benefits my point anyways of no blind spots).

    http://www.radartutorial.eu/07.waves/pic/OTH-SW.big.jpg

    The red waves are gigahertz and green waves that you see on that image are the HF waves. and they can cover those remaining 500 nautical mile blind spot by simply just not needing to use the ionosphere[/QUOTE]
    I didn’t miss that, you will noticed that i wrote OTH-B in my previous post
    There are two kinds of OTH radar with very different operating principles
    The Sky wave OTH radar, also known as OTH-B, they overcomes the earth curvature limitation by using very low frequency so they can “bounce” (scatter) their wave off the ionosphere, this is the kind of OTH radar with 2000-5000 km detection range and 900-2700 km blind range
    https://www.youtube.com/watch?v=2GVPdJzfiJE
    The Surface wave OTH radar, also known as OTH-SW, they overcome the limitation of the earth curvature by using a very low transmission frequency from 1.6-3 Mhz (could be up to 20 Mhz). These electromagnetic waves tend to bend around edges or curves, they are coupled to the conductive ocean surface forming a “ground wave” that can bend over the horizon and will follow the curvature of the earth, this is the kind of OTH radar without blind range but the maximum detection range is only around 300-400 km and they need to be on the shoreline because they relies on the conductive characteristic of the ocean.

    Even if you can merge the two, you still have the blind range.

    [QUOTE=”panzerfeist1]Although in my opinion its more preferable to have low altitude missiles that can use buildings or hills as cover from radars and missiles along with the benefit of being below the radar horizon[/QUOTE]
    At extended range, it better to cruise at high altitude because the drag is less so your missile can fly further

    are those missiles 700kg class and single fighter can carry multiple of them to Mach 1.5 speed. there is no point of carrying high speed missileif it inhibit fighter from going supersonic.

    Funny that you would say that since Flanker can’t carry multiple Brahmos nor can it reach mach 1.5 with multiple Brahmos light

    AARGM-ER is small enough to be put internally

    sparrow series are bigger but they have far longer range and better speed than Brahmos and KH-31

    already show you current warhead size is sufficient so they are making bigger warhead.

    You haven’t

    the largest single missile system programeme for strike called Brahmos only interested in increasing speed not making it slower.
    with current technology Brahmos can fly upto Mach 5 in newer version. but higher speed than that will need new materials and engine.

    hypersonic Brahmos hasn’t finished developement yet and it isn’t the biggest missile program either

    Also the nice Ventral area aircrafts have in comparison to missiles is drastic. I don’t think there are any airborne jammers as far as I know on aircrafts that can jam HF or stealth material that can absorb HF. I am sure the readings of an aircraft and missile to the amount of surface area they have can be measured out.

    As said earlier, at 2000 km, the 2 degrees beamwidth will be 87 km in diameter,so the area of resolution cell is 5944 km2, you think the slight difference between a fighter and missiles will make a difference when the cell is that big? No, it won’t, you can’t even separate aircraft in a formation apart.

    OTH radars provide multiple skip zones to cover for those blind areas

    No they don’t, when the approach angle reaches a certain limit, the wave will penetrate the ionosphere and can’t bounce back. There is good reason when you look at the coverage illustration of OTH-B radar, it is always a cut fan shape rather than the full shape

    you made a general statement saying “any normal” cruise missiles can fly both high and low I point out some cruise missiles that don’t.

    “Can perform a certain task” # “Will be used in such fashion”
    For example:
    B-52 can fly at low altitude, but no one use it that way, inefficient and doesn’t fit doctrine
    MOP can destroy tank, but no one will use it as an anti tank weapon, it a waste and too much collateral damage.
    Similarly, if you want, you can make a Delilah fly at low altitude, but there is no point.

    One more thing where in the image does it show it can fly 600 meters(I must be blind)?

    Yes, AGL stand for Above Ground Level

    The new MALD decoys that are not out yet

    Actually, it had been out and done several flight test in August 2018
    Unlike ROFAR that you talked about all the time, MALD-X had actually been tested in real world.

    But if that is as how low it can fly you can still distinguish it from a tomahawks 30-50 meter altitude estimation.

    What make you think Tomahawk, JSM, JASSM ..etc can’t fly at high altitude?
    Besides, what do you think the range resolution of OTH-B radar is?

    garryA
    Participant

    Sure its not used used as a firing solution but the information provided from OTH radars can be provided for classification purposes

    .
    The point is the resolution of OTH is simply too low, you can’t even distinguish individual aircraft in a formation, let alone classify individual missiles/decoys
    even with a beam width of only 2.5 degrees, at 2000 km, your resolution cell is a circle with 87 km in diameter, pretty much only useful for early warning

    True that there is a blind range but there are multiple hops at different angles that will provide coverage for those blind spots. See attachment.

    .
    There is a limit to how close you can hop (because otherwise your wave can’t bounce back), it called the skip zone, when you have a blind spot 800-2700 km in front of you, even if you magically classify and distinguish decoys and missiles before that, it is pointless.

    Provide me a source that shows the MALD has low altitude capabilities like the Tomahawk. Your telling me high and low altitude like “”””””any”””””” cruise missile is also wrong. The Delilah missile is considered a cruise missile but has absolutely no characteristics of it being low altitude..

    .
    Do you understand why Tomahawk fly at very low altitude while Delihah doesn’t?
    It has nothing to do with the aerodynamic or engine of either missiles but rather the fact that they added an altimeter on Tomahawk so that it won’t fly into terrain while fly hugging the terrain while Delilah is a search and destroys loiter munition so flying extremely low doesn’t benefit it, because you want sensor coverage.
    As for source on low altitude flight and MALD

    .MALD-X is a new version of the MALD-J missile developed by Raytheon. The collaborative project aims to demonstrate an improved electronic warfare payload, low-altitude flight and a datalink that will allow the weapon to communicate with other net-enabled systems.

    .
    https://www.shephardmedia.com/news/d…d-x-completed/

    .
    the MALD-X will have an improved electronic warfare payload, the ability to carry out low-altitude flight and an enhanced net-enabled datalink. Raytheon was awarded $34.8 million by the USAF to develop a new version in 2016.
    SCO says it plans to conduct additional tests on other enhancements to the MALD-X next year.

    .
    https://www.flightglobal.com/news/ar…l-flig-451403/

    The Navy said in April it is aiming for early operational capability of the MALD-N on the Boeing F/A-18E/F in 2021, and initial operational capability in 2022. The turbojet-powered, jammer-equipped decoy is able to fly for 90 min. or 500 mi. after launch to draw fire away from the fighter and suppress air defenses.

    MALD-N is expected to have some or all of the advanced capabilities demonstrated in two flights of the MALD-X conducted in August by the Pentagon’s Strategic Capabilities Office (SCO). The flights tested an improved, modular electronic-warfare payload, data link and low-altitude flight capability

    I am surprised you reply as more reply show limited knowledge.

    Talking to you is like play chess with a pigeon

    If subsonic missiles are such effective than why double the warhead weight?

    Because they can, when they don’t have to speed a large part of the missile for fuel.

    It will be much larger, the weight of its warhead will approach 1 tonne,” he noted.
    its world largest missile export project.

    So now you compare a land launched cruise missile to an air-launched one? what next? do you want to point out that R-36 has bigger warhead than Hydra 70?

    what formula they using it here?
    For instance, the destruction caused by the missile due to kinetic energy at mach 6 will be 36 times than the destruction caused if the missile hit the target at mach 1

    I can understand if English isn’t your strong suit but how come you are also terrible at Maths?
    KE= 1/2*m*v^2
    if your v is 6 times bigger while others part remain the same 6*6 =36
    How hard to grasp that?

    kh-31AD is 700kg missile with speed of Mach 3.3 range upto 250km. there is no counterpart in weight and speed in West.

    Except for ASM-3, ASMP, Rampage, AARGM-ER, AGM-69, Black Sparrow, Blue Sparrow, Silver Sparrow

    big nose of fighter radar can find slow moving fighter and missile release out from a distance and alert airdefence

    Unless if these missiles are stealthy, besides, you won’t be able to do sh*t against your opponents if they released their missiles from 1000-2000 km away, your air defense can’t touch the carrier, your chance of shooting the carrier down is exactly 0
    On the other hand, if they close in with 3000 kg missile under their belly, there are a lot of things you can do

    all new missiles are from mach 4 to all the way to mach 10. and only hypersonic research is worth spending on

    Seem like Russian hasn’t got that memo, you should tell them

    if US had more to win than to lose through the operation of both systems together, they would not be bitching so much, whatever the reason they don’t feel comfortable at all, despite gaining access to S-400 intelligence.

    Except they don’t have more to win, no one wants to give tech sensitive equipment to an “allies” who appear that they will have a good relation with your rival. Their concern is easy to understand.

    is also remarkable how several “allies” of US try to get access to an anti intervention insurance in form of the S-400, and the lengths they go to buy it, essentially pissing off US as hard as it gets… really remarkable indeed

    So looking at the topic of decoys the only way you can discriminate them is by using either passive radars and OTH radars?
    So how much of my assessment here is correct? And are passive radars and OTH radars the only defense against discriminating targets?

    Not only that you were completely wrong, but your conclusion is also completely opposite from reality, it feel like you try to come up with a “theory” that suit your agenda then cherry-pick information that sound like they support your theory
    passive radar and OTH are the literally the worst way to discriminate decoys from missiles/aircraft, their resolution are the worst out of all kind of radars

    The beauty of OTH radars is that they do not give a damn about what altitude you fly at because it uses HF waves that bounce off the ionosphere hence radar horizon does not apply. Decoys travel quite the distance but a radar such as this has quite the distance in detection

    The ugly part is
    1) You can’t determine altitude so OTH is useless for firing solution
    2) Because OTH-B radars have to bounce off the ion sphere, they have a blind range of around 800-1000 km in front of them. If you paid attention, their coverage always show that.

    Missiles like JSM, JSOW, HARM missiles with explosives can be identified at closer ranges(glide bombs even more identifiable at closer ranges) because these missiles are to be used at close ranges. Decoys can be launches farther away but that will make it easier to identify as decoys than the use only in close range JSM, JSOW, HARM or glide bombs. So I am guessing the only way to fool OTH radars is to launch the decoys at a closer range(which might be a bad idea since your making life more easier for fire control radars or not if your stealth), I have taken a look into these decoys and realize(correct me if I am wrong) they are released at higher altitudes and have a high altitude profile which suggests the decoys can be told apart from JSM missiles since there ranges have suggested high altitude release at 500km but goes at a lower altitude down the road, low altitude release at 185kms for low altitude flight

    JSOW-ER range is 550 km
    JSM range is 550 km
    AARGM-ER range is 300 km
    LRASM range is 1000 km

    MALD range is 900 km
    ITALD range is 370 km

    None of them are particularly close range, and MALD, ITALD are practically subsonic cruise missiles without a warhead, they can fly both at high and low altitude like any normal cruise missile with the same speed, the same limitation.

    the Tu-160 is fast it’s also very large and easy to detect and track. As a matter of fact the US and NATO would know the second they take off and track her the whole way. Which, means they’re in a very good position to intercept them. While, the Russian Bomber is unaware…

    Irrelevant, since Kh-102 range is allegedly longer than combat radius of F-35, like i said, modern interceptor can’t intercept bomber before they launch their missiles

    That would depend on the profile and many other factors. Nonetheless, that would also apply to any fighter not just the F-35.

    yes, that why i said speed and fast take off time is not as useful to interceptor is they used to be, since you can’t catch the bomber before they launch their missiles

    Those Brahmos specifications are 25 years old

    It can’t be since Brahmos only gone into service in 2006, besides your logic can be apply to Western missiles also

    the only thing claimed was 9 times energy of Tomyhawk on target.

    because they used this simple equation
    KE = 1/2*m*v^2
    and therefore more speed = more energy, but they didn’t care to take into account the differences in warhead mass

    I am sure ALCM version will provide even more speed since much newer

    Same goes for things like HSSW

    when has F-35 6 1000km missile operationally carried.?

    It can carry 4 LRASM (1000 km) + 2 JSM (550 km)

    lower altitude does not help .

    It does due to radar horizon + clutter.

    nor slow moving profile change.

    Whether you like it or not, it does help.

    [USER=”37608″]JSR[/USER] The only correct part in that is slow speed, the rest is incorrect.

    relatively small payload

    Brahmos warhead is 300 kg
    LRASM warhead is 450 kg
    JASSM-XR warhead is 450 kg
    KEPD 350 warhead is 481 kg
    Storm shadow warhead is 450 kg BROACH

    predictiable flight profile of 1000km missiles

    On the contrary, subsonic missiles have ways more unpredictable flight path since it is easier for them to change direction and they can cruise at lower altitude.

    make them easy intercept

    Unless if they are stealthy which pretty much a common feature for modern long range cruise missiles
    Besides, a single strike aircraft like F-35 can carry 6 subsonic cruise missiles or more, while even a Su-30 only carry 1 Brahmos

    cant used against real time targets.

    Unless if they have 2-way datalink, which is available on LRASM, JSOW-ER, JSM and many others cruise missiles

    only Brahmos has high speed S curve high speed dive feature so India implementing it on Su-30.

    S curve is not a unique feature of Brahmos, it is quite common on anti ship missiles
    and if you want high speed, you can also use aargm-er asm-3, rampage, silver/blue sapprow

    Sorry, try again as the Tu-160 cruises at Mach 0.9 (960 km/h, 518 knots, 596 mph). In addition the F-35 would easily detect, track, and shoot the Russian Bomber. Before it “ever” knew the F-35 was there…..

    That doesn’t matter when Tu-160 can stay at extreme extended range and launch cruise missiles
    Similarly, B-52 don’t really care about Mig-31 when its own cruise missile like AGM-86, AGM-129 can fly 2400-3700 km
    Soon enough, with JASSM-XR then tactical multirole aircraft can launch missiles from 1900 km away.

    At cost to be pedantic,comparison was between the max AB speed of the F-35 with the maximum supercruise speed of F-22,, so almost in case of the Typhoon and Gripen the same didn’t apply.

    Typhoon top speed is Mach 1.8, or barely 42 km/h faster than f-22 supercruise speed, you can pretty much apply the same argument about F-35 top speed for Typhoon top speed, yet it is still used in interception role
    https://www.raf.mod.uk/aircraft/typhoon-fgr4/

    And the mine’s own was to remind you that similar high load arrangements, highly debatable also when it comes to A2G missions make absolutely no sense at all in an A2A one, in any of such missions, so let’s imagine on an interceptor that as a general norm took off with a very limited payload in order to reach its own mission quote and speed a.s.a.p.
    Because it seems me that the thing that somewhat is missing there is a certain dose of historical memory: on how such missions were performed, what were the real performances requested to an interceptors (of better said to the different forms such formula has took as time go by) compared to a standard fighter, on how and why a tail-on engagement was always the preferred form of approaching bandits, of how A2S missiles work and so on…

    It depend on the requirement of the mission, in the 50s-60s, you need your interceptor to take off quickly and fly fast so they can reach and intercept bombers before they can drop their nuclear bombs, then in the 70s you want your interceptor to have very long range missiles so they can shot down bombers/strike aircraft before they can launch their own missiles. Nowadays when even fighter can launch missiles from 1000 km away, these requirements become rather questionable.
