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. 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.
