Media: Japan modernizes missile defense management system

24
The Japanese Ministry of Defense intends to modernize the automated missile launch detection and missile defense management system (Japan Aerospace Defense Ground Environment, JADGE) in order to be able to intercept North Korean missiles launched along a steep trajectory. This was reported on Tuesday by the Nikkei newspaper.


This system, using Japanese radar, monitors missile launches, compares the received information with data from US military satellites and from other sources, and based on the analysis of this information, calculates the expected trajectory of the missile and the place of its fall. If, according to calculations, the missile hits the territory of Japan, the ABM automated control system instructs the ships of the naval self-defense forces with interceptor missiles and the Patriot PAC-3 ground complexes to intercept.

Media: Japan modernizes missile defense management system


However, as military experts believe, in the event of a rocket launching not along the usual, but steep trajectory, as the DPRK did during the 29 rocket test in November, the automated detection and control system of the missile defense may not have time to make appropriate calculations and determine who launched the rocket - an ally or a potential adversary. In this case, the rocket at the final stage of the flight approaches the target almost at a right angle and at tremendous speed.

Modernization of an automated missile defense detection and control system is just one of the stages in strengthening the missile defense system in Japan. Tokyo, according to media reports, has already decided to actually purchase in the US and by the year 2023 to deploy ground-based counterparts of the Aegis-Aegis Ashore ship systems. For these ship-based and ground-based systems, Japan, together with the United States, is developing new SM-3 Block 2A interceptor missiles, which, according to the idea, should have a radius of up to one thousand kilometers instead of an estimated 500 km from the current SM-3. In addition to the 2020 fiscal year, it is planned to increase the number of Self-Defense Forces units using the Patriot PAC-3 complexes, from the current 17 to 28, reports TASS

      Oh, wise Opus, maybe because, despite your beautiful picture, the Onrakets either do not fly to Japan, fly over Japan, or fall in the territorial waters of Japan. And maybe air defense stations and systems are not the same thing as there is a missile defense system wassat

    Why Japan about?

    An underwater nuclear explosion that triggers a tsunami destroys half of Japan's economy.

    Japan must be afraid of a minimal conflict in the region, because out of the blue, someone from the owners of nuclear weapons will check such a trick by accusing a third party of this.

      To never again write about a nuclear explosion that causes a tsunami - once you find the energy of an earthquake that causes a truly destructive tsunami.
      I’ll tell you - we need energies of the order of 15-20 Gigatons.
      Your nuclear weapons, up to a hundred "kuzkin mothers", will not reach this order.
      And no less.

        If there is not enough knowledge, then it is simply better to remain silent sometimes. Especially climb with instructions to people more advanced in the sciences. What is 100 megatons, some just do not imagine. Earthquake energy i.e. the movement of tectonic plates and so on, which generates seismic waves and have a truly gigantic amount of energy. But it - the energy of seismic waves propagates in the crust, in rocks, etc., which transmit it very poorly. Those. in a solid medium, seismic waves are poorly transmitted and decay quickly. The epicenters of earthquakes are usually at great depths and even if the earthquake is huge, this does not mean that a tsunami will occur. It gives a sharp shift (raising or lowering) of the seabed, which is extremely rare. And houses and cities are destroyed by a small shake, because these buildings do not tolerate. With the strongest earthquake, being in an open area, absolutely nothing is threatening a person, he can’t even be knocked down, so he’s wobbling, more fear. Thermonuclear explosion gives a huge shock wave, i.e. a monstrous shock in the compaction of the medium (air and water, soil, especially rocky rocks also quickly quench them), a thin transition region propagating at a supersonic speed, in which a sharp increase in density, pressure, and air velocity occurs. This is best given by liquid, unlike gas (air), it does not compress and the shock wave propagates very well, and seven-meter waves of the Japanese tsunami reached Chile, across the globe in the form of two-meters. The tsunami causes: displacement of the seabed, giant landslides, the fall of space bodies and powerful explosions, both submarine volcanoes and thermonuclear. Therefore, kids need to study, study and study again, in order to understand how the phenomena of nature are arranged. Having gained certain knowledge, a person will no longer carry nonsense and deny the greatest achievement of mankind in the form of the possibility of obtaining such a huge amount of energy in a nuclear fusion reaction.

          Lord, how much pathos and stupidity.

          1. In an underwater nuclear explosion, 60% of the energy is simply extinguished by the water column and only 40% causes disturbance of the medium in the form of wave propagation in all directions.
          Only 40%. remember that.
          2. See full-scale tests of underwater explosions.
          Everyone tried to cause a tsunami - and everyone refused.
          I wrote real situations here a couple of years ago.
          Then spent a week.

          You started talking about the tsunami as if on command after Status-6.
          Since the year 67, the ideas of atomic tsunamis have gone into oblivion.

              Torpedo tube? giant? about the god-dear ....
              Limited charges give a lot of modeling information ...

              Do you understand that the energy of the movements of the earth's crust is measured in gigatons?
              Do you understand that the energy of a tsunami wave, which penetrates far deeper, arises only due to the movement of the entire volume of water from day to surface?
              There will be no general shift in the thickness of the water - there will be no wavelength of hundreds of kilometers, there will be no energy for the wave and it will not go anywhere further than 500 meters deep ...
              Yes, having blown up a 10 Gigaton charge, you will receive a wave of 500 meters high after 5 kilometers - but it will not have energy. It will not pass further than 500-700 meters by land, because this is not the movement of water from the bottom to the surface, but simply a disturbance of the surface layer ...
              During tsunamis, especially the present destructive one, a simultaneous movement of a part of the ocean surface occurs with dimensions of 150 km x 500 km and a thickness of 5000 meters of water.
              Can you imagine the sizes and volumes of water that immediately set in motion? And a sharp movement? The energy of the shift of tectonic pliz is beyond your understanding ...
              And what can 50-100 megatons in this comparison? Which, moreover, will spend 60% simply on the evaporation of water?
              Interesting information about the magnitude of the deformation of the ocean floor during earthquakes. In 1922, Japanese hydrographs measured depths in Sagami Bay, near Tokyo, and a year later, on September 1, 1923, a catastrophic earthquake occurred. Repeated measurements of the depths after the earthquake showed that changes in the bottom topography occurred on an area of ​​about 150 km2, while some parts of the bottom rose in places by 230 m, while others fell to 400 m. The rising part of the bottom pushed out a huge amount of water, which, according to estimates, amounted to about 23 km3
              . As a result of such a push, a huge water hill (solitary wave) was formed, which, when propagated, caused a rise in the water level off the coast of Japan in different
              places from 3,3 to 10 m.

              Only 3.3 meters with 23 cubic meters of water?
              And the energy of a powerful earthquake is hundreds of Exajoules ...
              Can you imagine how many orders it is above 50 megatons, when converting?

                I repeat, it is not the plate shift that causes the tsunami, not the earthquakes that occur every day and more than once in the bowels of the ocean, but special conditions under which the ocean floor is shifting. All gigatons go not to this, but to seismic waves, as a result of which they will shake the surface and quench. That's when the bottom shifted, then the tsunami went, as the bottom section fell / rose, such a tsunami will be, and a dead earthquake with a movement worse than the most powerful without a movement of the bottom. You at least understand this. 99,99% of the energy of plate movements goes nowhere, you consider the effective half of the thermonuclear bomb, and you forget that in the bowels there is also a expense for heating, electromagnetic energy, I repeat hard rocks - solid matter completely extinguishes. Here we have the formation of a bubble, with a diameter of 10-20 kilometers, apparently you do not understand this. And the formation of the wave height from the depression to the crest and its diameter, depending on the depth of the reservoir, the depth of the explosion, etc., is relatively easily modeled and calculated. Moreover, there were still low-power nuclear explosions under water and roughly taking them into account, monstrous results are obtained. Therefore, let academics do their own thing and just don’t make high-profile statements if you don’t have simulation results on hand, at least in the pool.

      10 March 2011 was a fairly strong earthquake with an epicenter off the Pacific coast of the northeast of Honshu, 400 km northeast of Tokyo. As it turned out, this was just a “preparation”.
      The next day, March 11, from the same hearth struck already an order of magnitude more powerful.

      Hearth, or hypocenter, earthquakes was at a depth of 25 km under the seabed, epicenter (projection of hypocenter on the surface of the Earth) - in 375 km northeast of Tokyo and a few dozen kilometers off the northeast coast of Honshu.
      The magnitude of the Japanese 11 earthquake in March 2011 of the year was 8,9, and, according to Alexei Zavyalov, it is likely to be in the top five of the strongest earthquakes on Earth from the 1900 of the year, when fairly regular observations began. Energy “thrown away” by an earthquake equivalent to a bomb in 50 megatons.

Recall that the tsunami that destroyed Fukushima ranged from 3 to 7 meters and only in the city of Miyako reached the same forty meters. Through the floor of a ball in Chile, the wave calmed down to two meters. But believe me at a distance of 24 km, the wave will rise several hundred meters, if not kilometers belay I repeat, the fireball had a diameter of 10 km, and this is the estimated 50 megatons that reached almost 60, exceeding the estimated power, i.e. the estimated 100 would have reached some 130-140, no one knows, but the diameter of the ball ... damn it belay and the wave, well, still using certain depths, the topography of the bottom, etc., you can get a certain orientation, where the damaging factor will intensify. And in the case of Beijing, which has a cup of mountains, and itself below, will receive another reflected wave in the return. Counted on dezstski, but .... in vain you are so smile

    At a distance of 10 km - a wave of about 400 meters
    At a distance of 20 km - already about 230 meters
    At a distance of 100 km, the height will be already about 50 meters.
    At a distance of 200 km - 20 meters.
    At a distance of 900 km - generally 4-5 meters.

      Let's take a break from your scheme. The maximum wave height from the hollow to the crest during the explosion of 100 kt at an average depth in a reservoir with the same depth of 120 m was 4,1 m, with a wave radius of 4,8 km. Again, very rude and multiply by a thousand, no not rude, multiply by 500, we get a circle radius of 2400 kilometers with a wave height of 2050 meters from the hollow to the crest. Those. from the surface we get a kilometer, as the initial wave parameters. Very roughly, we do not take into account the depth parameters, because it is necessary to explode at a kilometer depth in order to enhance the effect, the design power of the torpedo is still about 100 megatons, etc. Approximately 1,5-2 km wave in a radius of 3-4 thousand kilometers, as the initial value. The length of the United States from north to south is less than 3000 km (2700 km), i.e. The east coast is struck by a single charge in the right place, at the right depth. belay Roughly, but with a margin, and England in addition laughing
