FFL Najin Class
In the 1970s, North Korea unveiled the Najin-class corvette, which resembled the Soviet's Kola-class frigate produced during the 1950s. Only four of these Soviet inspired corvettes were built by North Korea, and two of these were soon decommissioned, Problems with their jury-rigged ship-to-ship missile launchers suggested that the two remaining Najin-class corvettes might be a greater danger to themselves than to any enemy combatants. The satellite image of Rasung Port in North Korea has been updated (20 March 2020). The Najin-class frigate 531 emerged from the dock, but it does not appear to have been refurbished. Ship 631 is the second of North Korea's Najin-class escort ships. It is the only warship over 1,000 tons deployed in the West Sea of ??the Navy. Sister ship 531 is located in the East Sea.
