    Kh-55/555, Kh-101/102 cruise missile: News

    Post  George1 on Tue Dec 18, 2012 2:48 am

    The Russian Air Force will accept into service in 2013 the new Raduga Kh-101 cruise missile, capable of delivering precision strikes with a conventional warhead at long-distance, an Air Force source told Izvestia on Wednesday.

    The new missile, currently being flight-tested, will be able to hit targets with an accuracy of just 30 feet (10 meters) at ranges of up to 6,000 miles (10,000 km), giving Long-Range Aviation its first precision-strike long-range weapon, the paper says.

    The Russian Air Force's bombers currently deploy the Kh-555 conventionally-armed cruise missile, which only has an accuracy of 75-90 feet (25-30 meters) accuracy.

    The subsonic Kh-101 navigates primarily by using Russia's GLONASS satellite navigation system, but also has a backup intertial guidance mechanism which can take over if its SATNAV is jammed. It will also be capable of hitting small moving targets like vehicles, the paper said.

    The new missile delivers a bigger payload - 880 pounds (400 kg) than its Kh-555 predecessor (440 pounds), and over a much longer range. A nuclear-armed variant, Kh-102, will also enter service.

    The long-range capability is essential as Russia no longer has bases abroad and therefore cannot provide distant fighter escort for its bomber fleet, Alexander Konovalov of the Strategic Evaluation Institute told the paper.

    The large size of the weapon means it can only be carried by Russia's biggest bombers, the Tupolev Tu-95MS and Tu-160, and not the Tu-22M3, which will continue in service with the Kh-555, the source told Izvestia.

    Now Ria is parroting the 10,000 km number that Izvestia made up
    ?

    Oy.

    why not? this is not a simple cruise missile, this a super super cruise missile

    Given the size of the missile, it is very much impossible.


    The range has always been stated as 5,000 KM, and then suddenly Izvestya pops up the 10k number.

    Well, this is a two ton missile, and the range of such a weapon would be greatly effected by its chosen flight profile and speed.

    A lower power setting for the engine, along with a high flight profile to maximise range and it could probably greatly increase its flight performance... actually it would be a great way to get around the INF treaty as the INF treaty bans ground launched missiles... ballistic and cruise missiles, with a range of 500km to 5,500km, so making a cruise missile with a flight range of 6,000km or more means ground based missiles become legal.

    taking the info at face value, precision of 10 meters isn't really that good for this day and age.

    Also, what sort of sensors does the missile use, since it is claimed to be able to hit moving targets. (why would a strategic missile of 5000 km range need to hit anything other than fixed targets is beyond me though)

    Its official accuracy is given as 10m, just like the CEP for Iskander is 10m but impacts of 3m or less were common in tests.

    With a 400kg HE warhead for the cruise missile and about 600kgs for the Russian model of Iskander, a 10m level of accuracy is good enough for most targets. Against area targets like a group of vehicles then a cluster warhead payload can be used too.

    Obviously for nuclear payloads this is far better accuracy than is needed.

    AFAIK it has optical terminal guidance that includes night capability.

    The ability to hit moving targets would largely be useful against ships, though the ability to hit moving targets suggests the ability to find its target even if it wasn't where it was supposed to be.

    Oh my.... Rolling Eyes

    Over and over and over alaways the same mistakes : in Russian literature missile's precision is expressed in Maximum Error Value or Index of Maximum Error (about 2,68 times the miss distance's standard deviation ), a measure about equal to 2,3 times the western CEP - Circular Error Probability .

    Therefore, if the information come from a Russian sources, in order to find the corresponding CEP of the Kh-101, you must divide the figure provided for 2,3.

    For those who are not sure what Mindstorm means let me give a short explanation.

    Very simply CEP or circular error probability is a measure of probable accuracy.

    It is determined using a standard bell curve of results.

    If you look at a standard bell curve most of the results are in the middle and are average while the very high and very low results are rare so you end up with a line that is on the zero line for 1 and 0 and bulges up around 0.5 in the middle forming a bell shape.

    It is zero for 1 and 0 because you can't have a probability of 100% certainty, just as you can't guarantee a zero% certainty either... 1 meaning no matter what it will always hit the target no matter how many times it is fired, and a 0 meaning it will never hit the target no matter how many times it is fired.

    Well that is not totally true... a Scud missile has a zero probability of hitting a target 10,000km away, but we are talking about a measure of precision on a target that is within reach.

    In the west a common measure is a CEP of 50% accuracy. In other words a CEP of 10m at 50% probability means that if you draw a circle around the point you are aiming for with a radius of 10m then 50% of the time the round or weapon will land within that circle. It basically equates to the middle section of the bell curve where the majority of the data occurs.

    In this case however the Russians are using the much stricter measure of CEP using the 95% accuracy, which can be derived from the CEP of 50% by multiplying it by 2.3.

    Which would give you the 95% CEP rating... if the same weapon had a CEP 50% of 10m then the CEP 95% would be 2.3 times larger, or 23m in radius.

    The best accuracy is CEP 99% which is 4 times the 50% CEP and would include many of the terminal phase malfunctions and of course high speed cross winds near the target and other natural effects that reduce accuracy.

    CEP 100% would include a failure to launch and therefore would be the radius of the range to the target.

    Different levels of probability are used for different purposes... 50% is often good enough for most tasks, and results in a nice small number that is good for marketing.

    95% is a more realistic reflection of reality.

    Of course the real problem is that some weapons might have better accuracy in a particular axis, so for instance a 122mm artillery shell might have a normal impact zone 60m long at 9km range, but the horizontal impact zone is only about 9m, so its impact zone is a long oval shape rather than a circle, and impact points for guided and unguided rounds are rarely so evenly distributed in a nice bell curve, so it is really an indicator more than anything else.

    The fact is that more often than not the projectile will land near the aim point and will only very rarely hit it dead on.

    6 Kh-101/2 (most likely cruise missiles fired from Tu-95MS)  thumbsup 

    Strategic bomber Tu-95MS cruise missile launches conducted on range on the Kamchatka Peninsula

    "One strategic bomber Tu-95MS bombers carried launches six new high-precision cruise missiles, air-launched using a multifunctional launcher ground targets on the Kura testing range aviation. Crew clearly worked on flight tasks, learning objectives at the site were amazed," -

    It has been confirmed the 6 missiles fired were of the Kh-101/2 "class". 

    Bummer there is little information to be found on these missiles, maybe more info will leak out in the near future.

    Ukraine has suspended deliveries of engines for cruise missiles in the Russian Federation

    AFAIK the extended range estimates for the Kh-101 and Kh-102 is because the Russians have developed a new more powerful but also more fuel efficient engine for cruise missiles to replace those made in the Ukraine for older Soviet missiles.
