LST 671 Un Bong LST

After service in the US Navy, these ships were transferred to South Korea on loan between 1955 and 1958. They were purchased in 1974. These US-built ships are of similar design, with minor differences. The LST 542 class ships (Un Bong and Hwa San) have a ramp connecting upper deck and the tank deck, while the others have an elevator. The ships can carry 2,100 tons of cargo including up to 20 medium tanks and have 4 LCVP landing craft on davits.

Various sources provide a somewhat confusing compilation of names for the various ships of this class, reflecting the vagaries of Korean transliteration.
