The destroyer Zumwalt became a problem for shipping because of its "invisibility"

98
The destroyer of the US Navy Zumwalt will be equipped with special screens to "increase the visibility of the ship for radar," reports Rossiyskaya Gazeta with reference to the resource VPK.name.




Such measures the US Navy were forced to go because of numerous complaints about the danger of navigation in the area where the destroyer is being tested.

According to the captain of a civilian vessel, “on the radar, the ship looks like an 12-meter fishing boat, while in reality the ship exceeds 185 meters in length.”

“The ship’s low radar visibility is achieved due to faceted forms and widespread use of radio-absorbing materials - the body with the superstructure is wrapped in a special coating of inch thickness, the number of protruding antennas is reduced to a minimum. After the tests are completed, the measuring equipment will be removed from the side of the destroyer, after which its mark on the radar will become even smaller, ”explains the publication.

Recall, the head Zumwalt (DDG-1000) was launched in 2013 g, 2015 was launched in December for sea trials. The launch of two other serial destroyers is expected in the 2016 and 2017 years.



Help "WG": "The ship’s low radar visibility has become a problem for shipping in the US territorial waters, but it is unlikely to make the ship’s modern anti-shipboard difficult. weapons Russia. Stealth technology was created based on X-band radar (8-18 GHz), while the Russian army is intensively equipped with "antistelsovnymi" means of detection and targeting. They operate on millimeter waves (30 MHz - 3 GHz) and clearly see ships and airplanes, no matter how bizarre they are. ”

    Invisibility is a relative thing and is associated with scanning equipment. And it will be necessary, then we will move into the visible range.

      Exactly. Cut it in half, whatever the tanker in the fog. In peacetime.
      And if anything, spray an aerosol over it, it will settle in the case and it will glow on the screens like a New Year's garland.

        Well, rightly so, you need to shine as it should, and not pretend to be a wick! The trouble came, from where they did not wait. And you can’t determine the type of vessel by a radio beacon? He gives radio signals, not in radio silence mode, saws through the waves.

            PR action. Do not believe it.

            As a sailor, I have the honor to inform you that on my not the newest (vessel built in 2006) and not the best (JRC) and far from military radar I notice WOODEN fishing schooner for 6-7 miles with a sea swell of 3-4 points without any adjustment. They do not constitute problems for navigation to me. Even the 3rd assistant Filipino somehow copes.

            I don’t want to get involved in theoretical disputes with local "couch" soldiers and sailors, but based on my own practical experience, I want to declare that this STEEL hr ... n height with a 9-storey building, I will see 20 miles without any passive and active reflectors and responders.

              Wooden (and plastic) boats you have the honor to observe precisely because they have fixed the same corner reflectors on the mast wink

              As for Zamvolt’s detectability in database conditions, you won’t see for 20 miles, since it’s only artillery for 80 miles that will greatly spoil your radar.
              What anti-ship will put him in the UVP as a result, no one knows at all yet.

              Therefore, here we habitually joke about "advertising", "drank", but Zamvolt is a serious prototype and a reserve for the future.

              And we have all the watchdogs riveting and with models from papier-mâché milling about the exhibitions, while some are exchanging apartments, but the children are being attached to the holy place of Vasilyeva ...

                Many times the radar flicked off birds, but somehow I spotted .... a whale (3-4 miles approximately)! The one that floated up and "let fountains", there were certainly no reflectors on them. wink

An article that civil ships do not see the "super invisible stealth", and therefore it can interfere with civil shipping, and this is nonsense and PR. Based on the above, I want to say that his invisibility is greatly exaggerated.

                  By the way, I wrote schooners, not boats.

                  No difference. Yachting has its own terms and we have everything that, roughly, up to 100 tons of non-commercial or military use - a boat. Boat. Sailboat, motorboat. And if the motorboat is stupid and rushing at the rate, it means "f .. yours, fuel oil trough" laughing
                  A "schooner" is simply a type of two-masted sailing rig. On the boat.

                  Boats in the Gulf of Aden with funny Somali guys we spotted for 4-5 miles. And there were no reflectors on them, believe me!

                  I do not believe. A close-knit bunch of oppressed Somali proletarians hung with AK and PKK shops - a great reflector!

                  therefore, it can interfere with civil shipping, and this is nonsense and PR.

      In radar, ranges from decameter to millimeter are used. In which exactly do you see him as a ball?
      For example, the Patriots work in the centimeter range and the S-400 in the decimeter range, and "Sky" in the meter range.

      That is, if a fishing boat is in the way of a civilian vessel, can it be ignored and rammed? This time.

      If the horizon (sea level) for a civilian ship is from about 8-9 km (what a small seiner) to about 20 (the height of the bridge is something very large), and for such a tall object as Zumvolt (height more than 20 m) it is about 26 -36 km, is it difficult to see and change course? These are two.

      What special radio-contrast panels are there to place? What is there to grow wise? It is enough to put several corner reflectors on the superstructure. Which can be done directly on board with existing repair equipment.

        But all the same, the ship turned out "for all the money." Had the Yamato emerged from the bottom of the sea, or even had Stalin finished building those super-battleships that Khrushch had cut down on the stocks, I would still bet on Zumwalt against any of them, or even all of them together.

      If a 185 meter ship looks like a fishing boat,
      there is no doubt that the fighter looks like a pin-pong ball.

      - However, there is an opinion that the Americans overdid it with stealth in aviation.

      The press wrote that the coverage of the aircraft needs to be updated almost before each flight - the coverage is unstable. Will they solve the problem and how soon.
      In the meantime, it can be assumed that in a couple of tens of minutes the ping-pong ball will turn into a soccer ball.

      Second, alternative direction finding technologies are being developed, such as radio shadow detection.
      And here the absorption of radio waves plays a negative role - the stealth plane is an ideal object.

      And the third thing - nobody canceled the distant "illumination". The contours of the aircraft are optimized to a greater extent for the radar of the enemy fighter, but the angle of reflection from the early warning aircraft is unpredictable. And the power is appropriate.

      We can conclude that stealth technologies work well only when a number of conditions are met. Who is right - will show the reality. But it would be better if they were not.

        "The press wrote that aircraft coverage needs to be updated

        There were coating problems - they worked out during the operation of the F-22.
        One of the Raptors already exceeded 1000 hours in the air, there were fast and the furious
        intercontinental flights from take-off in the Arctic to landing
        in the tropics (sudden changes in temperature).
        At F-35, the experience of REPtrov was taken into account, the coatings became durable.
        But a thorough inspection between flights is necessary.
        Russia will also soon face the challenges of supporting stealth coverage,
        when the T-50s begin to fly intensely.

        And on air defense radars - especially the F-35

      Do you firmly believe that the radars of civil and military courts are no different? Although I am not an expert in this, it seems to me that they cannot be compared in any way. That's why they are military. That's so expensive and big.

      As for the stealth in general and zumwalt in particular.
      We recall the course of high school physics and the properties of an em wave. In order to level the properties of a stealth object, it must be irradiated with a wave whose length is greater than fragments of the body forming this effect. The wave simply goes around the edges of this fragment and is reflected there from where it came.

    Even if it is really so subtle that it still needs to be proved. But his contours cause serious doubts. Ram ram type was typical for ships of the late XIX - early XX century. Due to the fact that such contours drastically reduce the seaworthiness of the ship, and ramming in modern naval battles became impossible, they were abandoned. Or do the creators of Zumwalt expect that the ship will be invisible not only radar, but also visually, and still go to ram?

    Well what can I say? I took a school formula from a physics textbook that allows us to calculate the wavelength of a radio transmitting device, knowing its frequency. So, lambda (wavelength in meters) is equal to the quotient of dividing the speed of light (in m / s) by frequency (in Hz). We substitute the extreme frequencies of the range indicated in the author's article.
    1. 30 MHz = 3x10 in the seventh degree. Divide the speed of light = 3x10 in the eighth power by the frequency (= 3x10 in the seventh power) and get ... 10 Meters !!!
    2 GHz = 3x3 to the ninth power. Divide the speed of light at this frequency and get ... 10 centimeters !!!
    Well, where is the millimeter range?!? fool

    This hut can only be invisible to a single ship, since the latter’s detection system will send an impulse and try to get a reflection at the point of location, but it won’t, because the locator signal will be reflected from the inclined surface in the other direction. For a group of ships, its visibility will be much higher, and even beautiful for one of them, in whose direction the echo will go. (Without taking into account losses on the absorbing surface, of course) For a group of coastal detection systems, there are no problems at all.

    "They operate on millimeter waves (30 MHz - 3 GHz) and clearly see ships and aircraft, no matter how bizarre they are." (C)
    The millimeter wave range is 30 (10mm) -300 (1mm) GHz. To the author - more closely with the numbers. It is doubtful that the frequency range above 30 GHz was actively used for target recognition radar (well, perhaps, in the very near zone), because in this range, the radio waves experience a strong attenuation. Normal rain disrupts the operation of the RRL in the 38 GHz range, and in the range of 50+ a dense fog above the sea will give a continuous flare. As a rule, the millimeter range in radar is used only as a meteorological one.

If we take the impact capabilities, then the boat can realize them no worse and the effect of low visibility radar will be achieved automatically. Equally, anti-ship capabilities can be realized on the boat, especially with an external target designation system. Shelling from artillery systems?

      air attacks ...
      But the Kyrgyz Republic is expensive, large, and their supply is limited.
      And Zumvolt’s whole trick is art. fire, not KR. Many, many super-long-range
      shells, and in the future also an electric railgun with its tiny arrowheads. The air defense frigate will have to cover it. Those. inevitably designing a stealth frigate air defense / missile defense.
      And it is also necessary to protect from submarines - Zumvolt. It is unlikely that he will be able to function independently.

          I won't say anything about the "Tomahawks", it is difficult to count them in the hold, but about the artillery range of 200 km with a projectile speed of 2 m / s and a weight of 000 kg is pure fantasy. At a distance of more than 10 km, it is required to use active-reactive ammunition with a significantly greater weight. In addition, a mass of 50 kg is enough only to damage the tank. As an example, the main caliber cannon, designed for the unfinished battleships Sovetsky Soyuz, sent a shell weighing 10 kg at 1108 km. There really was damage!

    If a ship shows its effectiveness, then a series of ships like Zumvolt will grow, if it turns out to be ineffective, then the series will fade. In any case, engineering thought should develop; thinking with old stereotypes is not always good.
