In South Korea laid the lead submarine project KSS-III

4
27 November 2014 of the year at the shipyard owned by the shipbuilding company DSME, was the cutting ceremony of the first steel for the head of the new submarine of the South Korean Navy. This is a large diesel-electric submarine project KSS-III (program Jangbogo III). This information was published on 28 November in Navy Recognition. Under the Jangbogo III program, a new Korean submarine is to be launched in the 2018 year, its transfer to the country's Navy is scheduled for the end of the 2020 year, after conducting two-year sea trials. The second submarine of this project will be ready at the end of 2022 of the year.


It is already known that the diesel-electric submarines of the KSS-III project will be built in three series:

- Batch-I will include two submarines built by DSME (Daewoo Shipbuilding & Marine Engineering);
- Batch-II will consist of three submarines built by HHI (Huyndai Heavy Industries) with maximum use of South Korean technology;
- Batch-III - Final 4 series submarines.

It is reported that the submarines of this project will be equipped with 6 launchers vertical launch. Doosan will create the launchers, and LIG Nex1 will launch missiles for them. At the beginning of 2014, the Spanish company INDRA was named Pegaso supplier of electronic warfare system, and the development of a control system weapons Babcock from the UK will be working on the KSS-III’s first series submarines. In addition, an official announcement was made at Euronaval 2014 that Sagem will supply optical-electronic periscopes for this project, and Thales will provide side acoustic antennas to South Korean company LIG Nex1. In addition, LIG ​​will present its command and control system for ships of the KSS-III project. Also, the submarine will receive lithium-ion batteries of South Korean production. In general, the project seems to be quite international.

In South Korea laid the lead submarine project KSS-III


Design work on the creation of a large (with surface displacement exceeding 3000 tons) non-nuclear submarine of the KSS-III project in the interests of the South Korean Navy has been carried out since 2004. Work is carried out jointly by two major Korean corporations DSME and Hyundai Heavy Industries. In addition to them, Hanwha, LIG ​​Nex1, STX Engine and Samsung Thales are working on the project. Technical assistance in the design was provided by the BMT company from the UK. Initially, South Korea even considered the option of creating an atomic submarine, but in the end it was decided to abandon this idea. As a result, the boat received an air-independent power plant, which is similar to that installed on those under construction for the South Korean fleet German submarines of the Type 214 project (KSS-II). The use of a modern air-independent power plant allows an underwater missile carrier to independently perform various combat missions in an underwater position for 50 days, as well as reduce the visibility of the submarine in the acoustic range.

According to preliminary information, the submarines of the KSS-III project were planned to be equipped with vertical launch ballistic missiles. According to one version, it can be Cheonryong ballistic missiles that are able to hit a target at a distance of up to 500 km. This missile is being developed on the basis of the Hyunmoo III-A ballistic missile, which is produced by the South Korean Defense Development Agency (ADD) and LIG Nex1. It is reported that in addition to the KSS-III submarines, the Cheonryong missile should become the main armament for the Type 214 submarines, which in South Korea are licensed by the German company HDW to Huyndai Heavy Industries.

In total, by the 2029, the South Korean Navy plans to have 9 new submarines of the KSS-III project. These ships should come to replace the German diesel-electric submarines of the 209 / 1200 project built by 1980-90-s currently in the fleet. At the same time, the submarine construction program of the KSS-III project in recent years has repeatedly undergone changes, it was delayed for financial and technical reasons. In the end, the Ministry of Defense of the Republic of Korea decided to issue an initial contract for the construction of only two combat ships of the first series KSS-III project, previously it was planned that the ships of the first series would have three pieces. If we talk about the submarine fleet of South Korea as a whole, now it consists of 9 submarines of the Type 209 project and four Type 214 projects, while the 5 Type 214 boats are at different stages of construction.



Curiously, the South Korean Defense Ministry "turned its face" to the submarine fleet relatively recently. The decision to create a submarine command in the country's Navy was taken only in 2012. According to the publication The Korea Herald, which referred to the representative of the National Defense Committee of the Korean Parliament, the creation of an undersea command in the Navy 2012 million won (639 thousand US dollars) in the country's budget 565 of the year.

The need to create a special submarine command in the country is explained by the fact that the South Korean Ministry of Defense submarines are classified as strategic weapons. Initially, South Korea planned to create such a command already in 2012, but this project turned out to be frozen.

Performance characteristics of KSS-III (Jangbogo 3) Batch-I:
Full boat length - 83,5 m.
Boat height - 14,7 m.
Boat width - 7,7 m.
Draft boat - 7,62 m.
Surface displacement - 3358 tons.
Underwater displacement - 3705 tons.
Submerged speed - 20 nodes.
Cruising range - 10 000 nautical miles.
The crew of the boat - 50 people.

    Great for a non-nuclear, 3000 tons of displacement! So they are going to stick a lot of weapons. And the striking progress of the countries of the Pacific basin. Literally 20 years ago, the fleet of Korea and China did not cause anything but grins. And now they are building excellent boats! And what about their projects. And boats with good characteristics. 50 days under water !!! It’s time for us to accelerate with non-volatile EUs ...

      No wonder. The shipbuilding sector of South Korea remains one of the country's leading export industries and a world leader both in terms of tonnage input and in mass shipbuilding and marine engineering technologies.

    South Korea understands that the regional submarine market is potentially large: Indonesia - now, the Philippines - tomorrow. Everyone wants to develop in this direction, and it is clear why the world's leading manufacturers are fighting for it. It can be said without exaggeration that this was a hundred years ahead for their industry. And this must be reckoned with. Because the dynamics of the promotion of military products in South Korea and ours are simply not comparable. First of all, on the efficiency and flexibility of the proposal. Here we lose even with very good projects, getting stuck in the bonds of our own bureaucracy. For example, the Commander-in-Chief of the Navy of Indonesia visited the stand of Rosoboronexport. The Commander-in-Chief expressed a desire to personally visit our boats. We always try to show them to foreign partners. But in our realities this is a rather complicated task. There are a lot of institutions with which such a visit needs to be agreed upon and which take part in making the decision. And it never gives an operational result. It turns out a kind of smeared responsibility. Someone should take up this matter and then receive all the bumps on themselves. And a very long struggle to make such a visit take place in principle. This is our weak link.

    Judging by the difference between surface and underwater displacement, the buoyancy margin is about 10 percent. Not much. On the surface in stormy weather, "walk" will be specific. But the combination of VNEU with lithium-ion rechargeable batteries is a definite plus. The "reserve" of the underwater course is noticeable. Optocoupler non-penetrating periscopes have already become the standard in submarine construction. It is a pity that not with us. In general, the project is interesting.

    The Koreans began the construction of missile submarines:
    - first (a few months ago) came news from the DPRK, along with obscure American spy photos

    The new submarine is estimated to have a length of 66-67 m, a width of 6,6 m, and a surface displacement of about 900-1500 tons. Commercial satellite images taken in July and August 2014 show that the position of the submarine in the water area of ​​Yuzhnaya Shinpo shipyard is changing, from which it can be concluded that the boat is undergoing sea trials.

    - and now South Korea has announced the start of construction of submarines (apparently NAPL) equipped with 6 VPU for missiles. Which ones - winged or ballistic are not reported, but I think - ballistic - in vain or something, in the 2012 year, the States agreed to allow them to develop ballistic missiles with a range of up to 800 km (the whole north falls), there used to be 300 km, now they are letting on 500 km . But the submarine and all of Japan within reach ...
    They plan to launch a new submarine in the 2018 year, to take part in the fleet in the 2020 year.

    KSS-III (Jangbogo 3) - while the project is called like this - will be built in three series, total 9 ships, approximate performance characteristics: 3.350 / 3.700т, 83,5х9,5х7,5 m, 20 knots, 10.000 miles ...

      Well, they have already been planning this boat for years. Years, no less. Only now they laid it down, because they themselves never developed.

      And the boat in the photo, as I understand it. Ordinary DPRK diesel engine of a new project.
      And I still haven’t seen their boats with a BR.
