    Great news..

    But if the dimensions are the same how do they achieve the extended range?...new type of fuel?

    This news came shortly after inf treaty end.
    Or oniks already had 800km range( and they only improved the navigation system), or a better fuel, I doubt they developed a new engine.
    I think they will "just" test the same oniks with software improvements. Which it's great.

    Expert: onyx-M missile tests with a range of 800 km have already been carried out

    According to the chief editor of Arsenal of the Fatherland magazine Viktor Murakhovsky, the range has been increased due to the new fuel composition, as well as a lighter and more compact onboard radio electronics

    The Onyx-M sea-based cruise missile with an increased range of up to 800 km has passed throw tests, before taking into service it is necessary to conduct flight tests at the declared range. About this TASS told a military expert, chief editor of the magazine "Arsenal of the Fatherland" Viktor Murakhovsky.

    "As far as I know, the throw tests have already passed, a series of real launches is needed to confirm the characteristics, and after that a decision will be made on putting into service," Murakhovsky said, answering the question about the timing of the appearance of a new missile in the fleet.

    Why develop old Oniks, apparently they have Cirkon with a range of over 1000km and a speed of 9M. Or Cirkon is in trouble. Onyks flight only 2.8M

    also modernized version has the same dimension meaning modernization can be applied to existing Onix models which was the idea of the modernization.

    Because they have hundreds or thousands of them...Zirkon is fine don't worry, not in production so low numbers,.
    But you knew all this, you're just trolling.

    They still need to answer officially to the ability of UKSK to use Zirkon. It may end up that only UKSK-M can use it and all the ship being constructed won't use zirkon.

    Oniks is the best antiship missiles today. Mach 2.8 and interacting btw them. It was designed to destroy new ships being designed in the 90s (so most of the nato ships in service right now). It also has a land attack version which no nato air defence can really intercept. System may intercept it but the AIDS most have can't deal with such low observable and very fast missile.

    They already stated that the smaller modified Zircon will go to standard UKSK. The smaller modification could even be quadpacked (although probably not) in the UKSK-M cell, and it also explains why the original range specifications for Zircon were significantly smaller...MOD wanted more range so they made a larger cell, which allows Kalibr to be modified to a version with 4,500km range.

    Sooo..

    How's about that Onyx with Mach 4.5 speeds?

    I suspect they also realised that having 200 UKSK launch tubes on big ships sounds fantastic but would actually be rather expensive to fill.

    Having a bigger launch tube means bigger missiles can be developed and used... the INF treaty did not apply to ship launched missiles... the American Navy insisted on that, and the US Air Force also insisted that air launched missiles are not included either.


    Having a bigger tube could mean the UKSK-M could use S-500 long range SAMs/ABM missiles, but would also mean that if they want to fit SAMs in it then it needs to be able to stack, and of course a larger tube is always better for stacking than a smaller tube.

    Onyx is in production and use today, so any upgrades can immediately improve performance across the fleet... interesting that they probably limited its speed because their is a land based shore battery version of the Onyx... the downgraded Yakhont is for export and has a range of about 300km, but the Russian Onyx probably can reach further... perhaps 400-450km while complying with the INF treaty.

    Whether ship or land launched range performance will be similar so an 800km range shore launched anti ship missile... with lighter electronics, probably lighter stronger materials in its design, improved fuel, and likely improved motor design, though probably still a ramjet rather than a scramjet, should significantly improve performance.

    How's about that Onyx with Mach 4.5 speeds?

    The increased power fuel should increase thrust so while the new Onyx might only have its engine running half as long, the extra thrust might give it a higher speed and therefore longer range.

    Say for instance it weighs 3 tons at launch, with 750kgs being payload and electronics and surface controls etc, and perhaps 750kgs of solid rocket fuel to lift the missile into the air and get it accelerating and climbing, that would be 1.5 tons left for fuel, so moving at mach 2.5 for say 350km, that is an 800m/s moving object flying 350km which should take 437 seconds, or about 7.2 minutes... the solid rocket motor would burn out very rapidly and speed should increase as it travels because it will be getting lighter as it flys.

    A new fuel, with perhaps both more energy and more volume might take up 1.8 tons of the weight of the original missile, but at mach 4.5, which means it is moving at about 1,440m/s, so 800km would take 555 seconds with 9.2 minutes of burn time with higher thrust.
