The Kawasaki Heavy Industries (KHI) plant in Kobe hosted the launching ceremony of the Soryu class naval submarine under construction for the Japanese Self-Defense Forces, reports TSAMTO with reference to Navyrecognition.com.


In Japan, the tenth litter-class submarine was launched


"510" Shoryu "(Shoryu) - 28-I submarine, built at the shipyard Kawasaki Heavy Industries in the postwar period, and 10-I Nasl class" Soryu "(5 built by Kawaski, 5 more - Mitsubishi Heavy Industries)" - says the material.

The boat was laid in January 2015, transferring it the fleet scheduled for March 2018.

The length of the NPS is 84 m, width - 9,1 m, height - 10,5 m, draft - 8,4 m, surface / underwater displacement 2950 / 4100 t, Crew - 65 persons.

The boat is equipped with a main power plant consisting of two Kawasaki 12V 25 / 25SB diesel engines and four air-independent power plants (VNEU) V4-275R produced by Kawasaki Kockums. The maximum speed in a submerged position - 20 nodes, in the surface - 12.

Armament: six 533-mm torpedo tubes with torpedoes Type-89, Type-80 and UGM-84C Garpun. The submarine is also equipped with a PU for shooting false targets.

It is noted that “equipping with an air-independent power plant allows reducing the visibility of the boat for sonars and being under water for about 14 days, unlike 4-5 days for diesel-electric submarines without a VNEU”. The submarine is also equipped with automated systems and GUS, allowing to increase the efficiency of conducting reconnaissance.

    Bad news. But there is no escape from rivalry at sea and we need to increase the pace of restoration of the Pacific Fleet’s power.

      The fleet definitely needs to be strengthened and as quickly as possible. In the meantime, keep a dozen RS-26 Rubezh aimed at Japan, just in case.

    In! Equipped with an air-independent power plant, but ours somehow, really some Japanese could, but we can’t do it?

        No, in general, the Japanese began as the Chinese now, if you remember.

      They have been dealing with this issue for a very long time, because they are forbidden to produce nuclear submarines. We do not have such a problem and therefore we were engaged in the production of nuclear submarines, and there VNEU is not needed. That's all.

        Work on the VNEU in the USSR resumed in the mid-70s. For a new type of submarine following “Halibut” Rubin has been trying to create a VNEU since 1987, that is, for a second, 30 years, and things are still there http://www.nntu.ru/trudy/2012/04/192 -201.pdf

      Yes, on Stirling engines, that is, it will still make noise. "The reasons for Japan's acquisition of a license for the Swedish VNEU are less obvious. Japanese submarines operate not only in inland seas, but also in the ocean. It is difficult to assume that Japanese companies could not cope with the creation of VNEU and infrastructure, and the military budget of Japan cannot be called extremely limited. however, Japan’s Naval Self-Defense Forces chose to license the existing installation rather than develop their own.As a result, the low power of the Stirling engines made Japanese designers "multiply VNEU by two" - on larger Japanese submarines, the installation consists of four engines, and not two, as in Swedish .

        They have and we need!
        It’s not very good to shove a nuclear reactor into a relatively small boat, the nuclear reactor requires special maintenance, replacing the fuel elements is worth it, the boat has specific noises (the engine works) and it needs constant water circulation (it generates heat, but there is no gradation).

          Teska. Let’s explain something to you. VNEU needs the boat to turn on the diesel engine to charge the batteries. Project 636,6 boats have a snorkel. Walking at recess depth, the boat can recharge the batteries. In either case, the boat can be heard for many km with its diesels. Hence the criticality of the presence of VNEU does not follow.

            Well, let's start with the fact that when the boat is in the RPD mode, the probability of its detection by radar, infrared, optoelectronic and acoustic means increases. The ratio of the swimming time under the RPD necessary to charge the batteries to the discharge period of the battery is called the "degree of negligence."
            Currently, there are four main types of non-volatile power plants: a closed-cycle diesel engine (DZC), a Stirling engine (DS), fuel cells or an electrochemical generator (ECG) and a closed-cycle steam turbine.

            So something like that, namesake ...

        Excuse me. but knowing the situation at the Pacific Fleet now, about our reality, it’s right to say: “Russians haven’t grown their grasp yet”
        And it is very insulting and painful.
        Japan's fleet surpasses Pacific Fleet.

    but somehow they wrote that yapy on lithium-ion batteries were going to transfer their boats. Or did something go wrong?

    It strains like such news. Japan is again militarizing, and as is known from history, it is dangerous for the Russian Far East. I hope our military bases on the islands and the Navy are able to crush if something happens .... You need to be on the alert with samurai !!!

    What, what, and the Japanese Navy can build! And the name of the Warships is generally beautiful! I have never seen anything like it - Mountain Fog, Shining Moon ... No names of admirals and in general anything related to war or aggression.

      The lead destroyer-helicopter carrier is named after the Japanese province of Hyuga in the east of Kyushu. He inherited the name from the battleship of the Ise type, built in the 1918 year and participated in the Second World War.
      Not so "white and fluffy" ... Japanese / Samurai ... request

    Well, if it is to be built by the end of 2018, then it turns out 4 years, for a small submarine it’s a lot, our Warsaw women learned to build in 2 years, as I remember, we are building more than 4 years, so it's not so bad with us

    Rivalry is inevitable. The submarine itself is good, but the harpoon spoils it. Not really there is no analogue? For us, the rival is not so strong but vigilance is above all!
