The Sariwon class corvette is a Soviet-designed corvette used by North Korea. They are based on the Soviet Tral class fleet minesweepers, but were built in North Korea in the 1960s. There are currently five active ships of this type in the Korean People's Navy. Stationed on the east coast, these ships were likely built at either Mayang-do Naval Shipyards or Bong Dao Bo Shipyards in nearby Sinpo on the mainland.
