[Exclusive] Vertical launching system for attack subs developed
Korea has developed a vertical launching system (VLS) [known as K-VLS or KVLS with, eventually, 10 cells for SLBMs] to be installed on 3,000-ton heavy attack submarines [KSS-IIIs] to be deployed after 2018, according to a shipbuilding industry source, Monday.
Hyundai Heavy Industries and Daewoo Shipbuilding and Marine Engineering are subcontractors for the heavy attack submarines.
It is the first time that the development of a submarine VLS in Korea has been confirmed. The Agency for Defense Development (ADD) has already developed one used aboard the 7,600-ton [KD-III Sejong the Great class Aegis destroyers].
A VLS is a modern type of missile-firing system used aboard submarines and surface vessels of several navies around the world. When installed on an attack submarine, a VLS allows a greater number and variety of weapons to be deployed in comparison to using only torpedo tubes.
Following the development of the VLS for subs, top shipbuilders in Korea and the ADD are also on track to develop an indigenous horizontal tube to launch torpedoes, cruise missiles and mines, the source said.
"The development of a vertical launching system has already been completed, while the development of a horizontal launching system is still under way," the source told The Korea Times, asking not to be identified. "Developing the horizontal launching tube requires more sophisticated technology than the VLS development."
The VLS would be used in launching long-range cruise missiles at key targets in North Korea.
The ADD has developed the 500-kilometer-range, ship-launched Cheonryong, which is a modified variant of the surface-to-surface Hyunmoo III-A ballistic missile [or Hyunmoo-3A (Tomahawk like) cruise missile?]. The missile range could be extended up to 1,000 kilometers, according to military sources.
The Cheonryong missiles are believed to have already been modified to be [horizontally launched from torpedo tubes on South Korea's] Type-214 subs.
South Korea has successfully developed the Hyunmoo III-C surface-to-surface ballistic missile with a maximum range of 1,500 kilometers, following the deployment of the 1,000-kilometer-range Hyunmoo III-B.
With the VLS development, Korea would have an advantage in selling its submarines overseas in the future, the source added.
Currently, the South operates nine 1,200-ton, Type-209 submarines and three 1,800-ton, Type-214 submarines. They are all diesel- and electric-powered and were all built with technical cooperation from HDW of Germany.
As Germany restricts the transfer of key submarine technology, such as launching tubes, Korea would have difficulty exporting any of those locally-built submarines.
The Navy plans to deploy at least three more Type-214 submarines in the years to come.
Beginning in 2018, Seoul plans to build 3,000-ton KSS-III submarines fitted with domestically-built submarine combat systems aimed at automating target detection, tracking, threat assessment and weapons control.
The heavy attack sub will be armed with indigenous ship-to-ground cruise missiles and be capable of underwater operations for up to 50 days with an upgraded Air Independent Propulsion (AIP) system.

PETE COMMENT
So South Korea seems to retain confusing ambiguity on whether its new submarine missiles will be:
- usually conventional explosive cruise missiles (SLCMs) that are usually low flying,
subsonic or mildly supersonic (if conventional adhering to the NPT)
subsonic or mildly supersonic (if conventional adhering to the NPT)
OR
- usually nuclear explosive ballistic missiles (SLBMs) that are almost always high flying
and hypersonic (if nuclear breaking the NPT in the same way North Korea already
breaks the NPT).
and hypersonic (if nuclear breaking the NPT in the same way North Korea already
breaks the NPT).
Note that a submarine firing merely conventional explosive cruise or ballistic missiles would represent a very expensive launch method for little explosive effect. Also submarine launched cruise or ballistic missiles from a nuclear capable country (like South Korea) might be seen as nuclear armed by nuclear armed countries - usually demanding a nuclear response.
If Israel's Dolphin submarines fired their cover-name "Popeye Turbo" missiles at Iran then Iran would consider these missiles to be nuclear until proven otherwise.
There is also a myth that ballistic missiles might carry other special warheads (by they biological, chemical or radiological payloads). Over the years critical military installations (eg. deep dug command or "Kim" VIP centers or hardened long rang missile silos) have developed air conditioning or separate oxygen defenses that are only vulnerable to the blast penetration of nuclear weapons. So it is likely that South Korea's mature and final submarines ballistic missiles (in the late 2020s/or 2030s?) will be nuclear armed.
