North KoreaReported count for Hainan class. Service scope: Korean People's Navy; does not replace a national total. 1 distinct count cell(s) from the same source list; shared rowspan cells counted once. Retired, wholly reserve and on-order rows are excluded; the reported count retains any explicitly mixed stock scope in the quoted row. Count column(s): in service: 6. Origin: unstated. The listed variants/roles are the scope, not an immediately deployable count. The components do not establish one inventory census date; the stored date is the retrieved source snapshot.
