Udo Naval Base

On Udo, one of the five islands in the West Sea, the tense atmosphere of a battlefield without gunfire continues day and night. Facing directly toward the edge of North Korea’s Yeonbaek Plain in Hwanghae Province and positioned like a dagger pointed at the entrance to Haeju Bay, Udo is the ROK forces’ most critical strategic stronghold guarding the West Sea. Although the island’s circumference is only 3.4 kilometers, its sheer cliffs, fast currents, and natural caves make it an impregnable fortress.
