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. ”

        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.

              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.

                  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.

      - 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.

        There were coating problems - they worked out during the operation of the F-22.

        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.

      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.

    Again, not the topic. I can not understand the value of the destroyer class ship. 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? Guys, yes, you knew how to drive a scow of such a cost to the shore with such a risk that it could be seriously consumed by self-propelled guns for the price of a couple of evergreen lemons ...
    Anti-submarine function - do not tell me, as well as the function of the carrier. Can it be easier and cheaper to accept a pair of "submarine + air defense frigate"? And the specific tasks of supporting the landing and hunting for enemy submarines should be given to specially trained ships?

      The idea is quite healthy. The submarine fires the Kyrgyz Republic, and frigate it covers from
      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.

          For Zamwolt, General Atomics has developed a gun capable of delivering a 10 kg projectile over a distance of more than 200 km at an average speed of about 2 m / s, and is developing up to 000 km in the future.

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!
