Programmes: Three `Sariwon' class built in Korea in the mid-1960s. The two `Tral' class were transferred from the USSR in the mid-1950s, were paid off in the early 1980s but one returned to service in the early 1990s.
Structure: The Sariwon design is based on the original USSR Fleet minelayer `Tral' or `Fugas' class in service in the mid-1930s. Minelaying rails are visible along the whole of upper deck aft of the bridge superstructure. Sariwon 671 is one of the original `Tral' class built in 1938 and restored to service. Some variations in gun armament and one Sariwon is reported as having sonar and an ASW armament.
Operational: All ships are based on the east coast (Changjon) and, despite their age, have been reported as seagoing. Pennant numbers 611, 612 and 613 have been reported.

Их же корейцы корежили неоднократно, как я понимаю. Но, по Conway's 1947-1995, на 1993 год в строю оставались только бывшие "Стрела" и "Параван". Правда, как они это определили - фиг его знает.
Вообще, видимо, этот "671" - старейший морской боевой корабль в мире, остающийся на службе (если не учитывать латиноамериканскую речную экзотику).
