Should a navy choose the German Type 212 or South Korean KSS-III?
Short answerType 212 better suits shallow and constrained waters, while KSS-III is favored for open-ocean and long-range patrols.
NotesType 212 is preferred for shallow-water work, while KSS-III is favored for long-range patrols in the open ocean. That comparison becomes less straightforward when Type 212CD replaces Type 212A: its suitability relative to KSS-III is disputed. A claimed twenty-day endurance advantage is treated as provisional because the new variant is not yet in service. Endurance and range are also distinguished rather than treated as interchangeable figures. KSS-III's vertical-launch system provides a further reason to consider it for area denial.
