There are reports that the ROKN have tested a SLBM and that the new Dosan Ahn Changho class SSK about to enter service will be the SSBK. Whilst the warhead is a conventional one and the platform a SSK variant, at some stage in the future the ROK may decide on a SSBN with a nuclear tipped SLBM. At present it is thought that this capability is a deterrent aimed at North Korea, but with suggested ranges of 300 - 500 miles it would bring parts of the PRC within range as well. That will create shrieks of shrill self righteous outrage from Beijing.

Israel is supposedly fitting SLBMs to SSKs so it can be done and like Israel, the ROKN don’t need to conduct long distance Patrols for 3 months at a time. So can probably get away with AIP. Of course officially Israel doesn’t have Nukes either.There are reports that the ROKN have tested a SLBM and that the new Dosan Ahn Changho class SSK about to enter service will be the SSBK.

If we see the model of KSS3, they have 6 VLS missile tubes. Officially (at least what Hyundai said) it is for launching cruise missiles. Just like Russian Lada class SSK.
However if they put small diameters balistic missile like what Indian did, then it's probable those tubes (which is officially for cruise missiles) can fit it too. Whether cruise missiles or small diameters balistic missile, if KSS3 already equiped with that facilities, then they should have enough sensors build to guide the missile.

Yesterday the first of KSS-III class of advanced submarines was commissioned by the South-Korean Navy.
Eight more of these 83,5 meter long pieces of black steel are planned, from which two are already under construction.

ROK Navy Commissions Her First KSS III Submarine - Naval News
South Korea commissioned its first Dosan Ahn Changho-class (KSS III program) submarine today. ROKS Dosan Ahn Chang-ho (SS-083) was built by Daewoo Shipbuilding & Marine Engineering (DSME) for the Republic of Korea (ROK) Navy.

The FFX IV program has been approved for the ROKN. The program consists of 6 ships with the first one to be delivered by HHI in 2024. The ships are to have a fully loaded displacement of around 5,000 tonnes. They will be fitted with an AESA radar. I would not be surprised if they aren't fitted with the LIG-N 30mm CIWS as well, which is supposed to be in service by 2025.

FFX Batch I (Incheo) : 6 ships
FFX Batch II (Daegu) : 8 ships
FFX Batch III (Ulsan) : 6 ships
FFX Batch IV : 6 ships?
1. Yes, the 6 FFX Batch-IV frigates will have the following hull numbers; FFG 836, FFG 837, FFG 838, FFG 839, FFG 841, and FFG 842.
2. The exact specifications of the FFX Batch-IV frigates are not yet known. Their displacement is expected to be between 4,500 to 5,000 tons. Some have pointed to conceptual designs proposed by Hyundai Heavy Industries (HHI), as being an indicator of what the FFX Batch-IV will be like.
Edit: 3. The 3,500 ton FFX Batch-III frigates are 129 metres in length and a width of 15 metres with a top speed of 30 knots — with a 4-sided fixed multi-function phased array radar capable of 360 degrees detection, tracking and engagement.
(a) Computer-generated imagery that accompanied HHI’s media release suggest that this equipment could either be the ELM-2248 (MF-STAR) multifunction surveillance radar from Israel’s ELTA Systems, which is also found on the RoKN’s second Dokdo-class amphibious assault ship, or an indigenously developed product of South Korean company Hanwha Systems.
(b) First ship to be delivered by HHI in 2024, after the US$325 million contract was signed in Jun 2020. For FFX Batch-III, Rolls-Royce will also supply Engine Health Management capability with its MT30 marine gas turbine.

@Sandhi Yudha & @OPSSG I stand corrected. Mea culpa.
Hey OPSSG
At point 3 in post #428. Have the Batch III's shrunk down to 103 metres? Surely not.
There has been some confusion in the Korean and Japanese defence blogs about what the FFX-IV will be with the KDDX. The accepted impression is that the KDDX is looking like quite a radical 8800 tonne vessel, where as the FFX-IV will likely be a design evolution of the KDX-II Destroyer hull (Hyundai's HDD-5000 design) with the more modern superstructure design similar to the FFX-III. No one is sure what the propulsion will be, for example will an evolved HDD-5000 hull for the FFX-IV use the MT-30?

Sorry, I got it wrong too. Edited it to 129 metresHey OPSSG

1. A few years ago, I was speaking to a person who helped spec the Formidable class and it was explained to me over lunch that shaping for signature management (so called ‘Stealth’ for ships that size) is not as important as many in the Singapore press think — because the ship’s RCS signature is always there. He was more direct than what I can say here (that person said it without revealing anything OPSEC). It was then I understood.
2. Often the design goal of RCS management on frigates and destroyers is to confuse the enemy, rather than be ‘invisible.’ The goal is mis-identification. For example, the signature return of the 76mm gun on the Formidable class could be further reduced, but the Singapore Navy didn’t bother. Rather, I think you have to look at the design and how it can aid spoofing (on the side of blue forces), emissions and emissions direction finding (to detect the enemy) is more important.
3. The US Navy has ensured that the 7th Fleet’s destroyers are all equipped with the AN/SLQ-32V5 —a peripheral system largely known by its nickname "Sidekick." This system gives the vessel extended 360 degree jamming capability and is meant to counter the growing threat of ever more complex anti-ship missile systems proliferating around the globe.
(a) The new Block III iteration of Surface Electronic Warfare Improvement Program (SEWIP) takes these capabilities to a whole new level and other enhancements in signals management capability that is more advanced than the rest of the US Navy fleets — there is an article on the SEWIP; and it also covers the Transportable Electronic Warfare Module (TEWM) was designed from the outset to be reconfigured easily to address emerging threats and can be easily moved physically and integrated onto new platforms.
(b) The Japanese don’t have that level of EW and signals capability but they are getting there. RCS management is a manifestation of Japanese future intent to own the electromagnetic spectrum viz a viz the Koreans and Chinese.
(c) RCS management on Korean vessels is a cool thing but it needs to be integrated with signals management plans that fit a certain war fighting concept. The Japanese have bigger power and cooling reserves to install more equipment than most — but such level of emissions integration is not simple to achieve. When the technology matures or at mid-life upgrades, there will be more ‘things’ installed on both Korean and Japanese destroyers — it’s a competitive cycle.

They operate in very different environments.
The korean and japanese (and singaporean) ships operate in extremely busy areas, in many cases I would imagine, signature reduction to just be a lower level or a level similar to commercial ships would make these much harder to target and track in the opening stages of a conflict.
The RAN essentially operates in empty seas. Pretty hard to blend when there is nothing around.
This also impacts on radar strategies between nations and what you expect your radar horizon to be, tactically. In a lot of cases, weapons might be cued by other assets or quite close. Shooting at a radar blob in the middle of a bunch of radar blobs is tricky business.

The ROK Navy completed the final phase of the Korean Submarine Launched Ballistic Missile (K-SLBM) development, by successfully launching a ballistic missile from a KSS-III 3750t submarine under water. South Korea has now officially become the 8th country in the world that possesses indigenous SLBMs, after china, France, India, North-Korea, Russia, United Kingdom and United States.
The brandnew KSS-III Dosan Anh Changho SS-083 has 6 533 mm/21" torpedo tubes and 6 VLS silo's.

Bemil Chosun put article on DSME won contract to build KSS3 2nd Batch. Based on Naval News sites (that also shown similar article) the Batch 2 will be around 4000 ton compare 3000+ ton on Batch 1. This more to VLS that enlarge from 6 to 10. No confirmation on the length that I can find, but speculate it will increase from 83+ meter on batch 1 toward close to 90 meter.
DSME now become the leading yard in South Korea on Submarine building. Imagine that on some Indonesian so call Defense Industry Insiders (including the tweeter guys) keep put doubt on DSME products quality. Talking on independency of Defense Analyst toward business competition.

Link to Bemil Chosun on the video of first ROKN SLBM launch. This launch then being answer by North Korea rail launch KN-23 balistic missiles.
Seems the North realise that they do not have capabilities at this moment to catch up with the South Submarine Tech. Perhaps this rail launch system, is their answer.

The similarities of both the launch and shape of the new missile with the ones of Yakhont/Brahmos, may indicate the involvement of Russian designers, or at least their technology and expertise.

ROK according to this article, provide much larger conventional warhead on Hyunmoo, compared to similar class Balistic Missile. Understandable considering ROK did not have nuclear warheads, thus they want their Balistic Missile to provide as much as destructive powers any conventional warhead can provide.
I'm just speculating in here, if they see one day that US Nuclear Umbrella is not as dependable as it used too. Then they can develop their own Nuke warheads, as they already have technology to do that. While now they're working on the delivery medium.
