For the first time shown the homing head of the Ukrainian rocket "Neptune"

65

For the first time in Ukraine, the homing head of the P-360 anti-ship missile, which is part of the RK-360MC Neptune complex, is presented to the general public. Despite the signature stamp surrounding products of this type, some characteristics of the designated equipment were disclosed.


Allegedly, the homing head of the P-360 Neptune cruise missile, developed by Radionx, refers to a combined active radar dual-band type. She is able to recognize the target at a distance of 50 km, being resistant to interference generated by the enemy.

During the first stage of the flight, the RCC, following a low path, is controlled by an inertial system that works in conjunction with satellite navigation. When approaching the target, the rocket rises to a height of several hundred meters and includes a homing head. After recognizing the object to be destroyed, the anti-ship missile system returns to ultra-low altitude again.

In this case, the rocket is able to follow actively maneuvering targets, since the head has maximum deflection angles of ± 60 °. For comparison, the American RCC Harpoon, a similar indicator is ± 45 °. In Ukraine, they are proud that in this indicator their rocket is superior to the American one.

According to the military department, it is planned to complete state tests of the Neptune complex by the end of this year.

    repeat We are also proud, now she will be able to fly to where they did not let her go. Everything is good in moderation. repeat

      I suspect that Soviet designers were already proud of the maximum angles a long time ago. Do not go to a fortuneteller, second-hand.

    Here is something standard, you can really not invent and try to do it on the knee. Just BUY, it will be much better.
    And so, in the case, it is necessary to restore industry, production and the scientific and design base.

      Well, we have one too, then they promised 30 senies, then 20, and now they’ll do 9. In fact, the same story was with the frigates, they promised an armada, but in reality they only let down 2 since 2006.

      Your questions to our zircon lovers)))
      Most likely, coastal complexes will be guided by radars included in the complex. Naval radar (if they can find ships and install these anti-ship missiles) or aviation radar (if they can install them on airplanes).
      And yes, there is a critical shortage of missile search and guidance tools in Ukraine.
      As for the electronics - perhaps it will be even easier for them because they will be able to purchase foreign electronics (it is no secret that this is not all right with us).
      As for entering the series - yes, there is a possibility that the series will not be.

      This happens all the time if the article is about Ukraine or India.
      In the case of bringing this Neptune to mind, our patrol and border ships that do not have air defense systems, as well as RTOs and even frigates 11356, will face a serious threat from Ukraine. These devils are not afraid to provoke at the most inopportune moment. This will have to be taken into account.

        I don’t think that Ukraine would dare to attack any Russian ship, since it understands that on the one hand the entire Black Sea is blocked by our air defense system located both in the Crimea and on ships, the speed of the S-400 / Poliment-Redoub launcher reaches 4800 meters / second is 17 km / h, and on the other hand, an attack on a Russian ship or military base in Crimea will mean a declaration of war and then nothing will save Ukraine.

        So, RCC Neptune is not a critical threat to the Russian fleet and naval bases.

        Let them shout, they will rejoice, and then they will understand that this rocket will not help them in any way, either militarily or economically.

        A rocket of this type, Harpoon, USA, X-35 Russia costs about $ 300. Let them spend budget money, less will go to the ground forces.

        But the Russian fleet is not such a threat.

The upgraded versions of the Bal and Uran missile launchers were adopted by the Russian Federation 15 years ago, supplied to India, and maybe even more, so there’s a share of jokes about buying Chinese components on Ali ...

              As far as I know, in Ukraine, the terms "acceptance 1" (factory quality control) and "acceptance 5" (VP or PZ) are not used at all, they work according to the old GOSTs of the "B" series. VP accepts, if his participation is prescribed in the contract (the Contractor is hung up wassat ), and if not, then at best pocket OTC. Well, anti-ship missiles do not fall under "9", not space after all.
              It looks like it's a layout. And from the layout to the prototype - how many. And to the series even further.

    Eugene! Do not forget that the neighbors are still not all collapsed to zero. And if my sclerosis doesn’t fail me, then the Artem software at one time was engaged in precisely air-to-air missiles and precisely with GOS. For the Union, by the way. So do not console yourself with the illusions that they have enough components for a couple of rockets and that’s all. It’s better to accept, in their calculations, the condition that they can establish a series and accordingly counter the threat, and then not scratch their turnips and not ask themselves a question, but “where did they get so much”
    As the ancients say, “Hope for the best, but prepare for the worst.”
    As for the rocket flight algorithm, it is absolutely identical with ours and the American version. We also have the same “Caliber” at launch it rises to a height of about 150 meters, accelerates to a marching speed, then drops to the SMV of about 10-15 meters and goes on inertial. About 40-60 kilometers from the approximate location of the target, the Caliber rises to a height of 400 meters, the target is captured and again descended to a height of 5-15 meters. Similarly, Neptune
    Who will issue the primary target designation? Well, they still have planes, as well as radars. This is not 700-900 km, but just a couple of hundred ...

        funny because they were laid back in shaggy years. And under the armament. There was no RCC.
        Then we decided that it would be more profitable to create our own anti-ship missiles and put them on all platforms. We saved the fleet (with European weapons) and let's rive the anti-ship missiles. By the way, it turned out cheaper than one corvette.
        When laying the Corvette project, Ukraine did not have RCCs; everyone decided to buy in Europe.

    So this is for aviation. But are there any EW means at the same Buyan-M or Karakurt - that’s the question. The fact that there is no air defense is already a minus. And such ships can become quite easy prey for anti-ship missiles

      At these IRAs, air defense systems are quite adequate to the displacement. There, and the rocket is far from a mineral. Vitality below the baseboard.

    Yes, but for some reason they are going to arm their new corvettes not with RCC Neptune, but with French RCC Exocet. Funny, isn't it?

    Maxim! They have been carrying models of this corvette at EMNIP exhibitions since the beginning of the 2000s, it seems from 2002. First it was project 58200 "Haiduk-21", then 58250 (since 2012). Then they did not think about their RCC “Neptune”. By the way, the corvettes of this project could be armed with both “Uraniums” and “Exocet” (artillery is also our 100 mm, and “Oto Melara”)
    The first such corvette was laid back in 2011 and its readiness is about 50%. So it is not known whether he will be at all, not to mention what kind of RCC there will be

    This homing head should respond especially well to fat with a chorus, capturing it at any range, in any weather conditions and when the enemy uses electronic warfare equipment.

    Do you think that MANPADS are a sufficient means of protection against anti-ship missiles?

    And who saw this model beside the photographer? That's when our satellites will record launches and the most important defeat of goals then progress. And just a pan with phased lattice.

    Ukrainians have already shot down planes .. Now civilian vessels will begin to sink too ..

    - "In Ukraine, they are proud that their missile surpasses the American in this indicator" - wait for sanctions !!!. They will not forgive you for this, they will stupidly prohibit production because a slave should not be smarter than the owner.

    Video of network launches wagon and small truck. Video hits on the target is always very, very small. Sometimes it doesn’t happen at all. For example, I HAVE NEVER SEEN a hit of a "Caliber" in a sea target. But this does not mean that such a missile does not exist with us and it does not hit the target. Sorry, but your conditions regarding the provision of video information about start-up and defeat are an attempt to "save face" by saying that our "neighbor" cannot do anything.
    But in vain. With such neighbors, hoping for the best, you still need to prepare for the worst. And to be prepared for the fact that they can equip their small fleet with this complex, like the coastal units ...

    The fact that the Ukrainian GOS has surpassed the American warhead half a century ago in its performance characteristics (survey sector) is no reason to ban production in Ukraine. America, this GOS is a damn thing. Moreover, other parameters are completely unknown. Interference immunity, selectivity and other parameters of the GOS (except for the enlarged sector)

    It should be noted that the expert who wrote this collected information from TK on such complexes, believing that it was done according to such principles. An antenna is assembled from segments of 3 elements; these segments are located at the edges. In the center are segments of 4 elements and 6 elements. The fact that the elements are not identical indicates that it was necessary to reduce the mutual influence of the elements on each other. This was done in order to build a monopulse system. In general, such a "masterpiece" gives its creator as not experienced in the design of antennas. They tried to reduce the influence as much as they could ... The antenna was built on the so-called patches from Rodgers 5880. Powering each patch also spoils the radiation pattern of a single emitter. I can only sympathize with the developers how much time and effort it took them to such patterns and ornaments. The antenna constructed in this way is rather narrow-band no more than 2% of the center frequency. Single-range homing head for sure! The following conclusion speaks for itself that a locator with such an antenna will be easily muffled, because it works in a very narrow frequency band, there is nowhere to go from frequency interference to the left or right, 2% of the band! Judging from the dimensions of the patch somewhere around 14-19 GHz, the operating frequency is difficult to determine by eye. The capture range at these frequencies is three times less than stated! 12-15 km.
    It’s not clear to me how a little tidied up to such topics, why should this be laid out for consideration ?! Either they completely think that they have done something worthy or this is one of the trial options. Such antennas need to be made waveguide-helium.
