South Korea Names New 3,600-Ton Submarine 'Seo Hui' After Historical Diplomat

The South Korean Navy has named its second 3,600-ton class submarine of the Jangbogo-III Batch-II program 'Seo Hui,' honoring a prominent historical figure renowned for his diplomatic prowess. The naming ceremony, conducted by the Navy's Ship Name Committee, selected Seo Hui (942-998), a statesman from the Goryeo Dynasty, for his pivotal role in securing the strategic Gangdong Six Counties.

Seo Hui is celebrated for his courage and intellect in confronting a massive Khitan Liao Dynasty invasion. Facing a formidable enemy force, he skillfully negotiated with the opposing general, persuading them that retreating without conflict would be more beneficial for the Khitans themselves. His diplomatic success led to the withdrawal of the enemy army and the acquisition of crucial territory for Goryeo.

The Navy explained that Seo Hui was chosen as the namesake for this key maritime defense asset due to his exceptional military and diplomatic achievements and his spirit of overcoming national crises. This aligns with the Navy's tradition of naming submarines after individuals who have earned national respect through contributions to military strength, maritime power, scientific advancement, or struggles for independence.

The Jangbogo-III Batch-II submarines, displacing 3,600 tons and measuring 89 meters in length, represent a significant upgrade from the 3,000-ton, 83-meter Batch-I Dosan Ahn Changho class. Improvements include enhanced sonar systems for better target detection and processing, and an increase in vertical launch tubes for Submarine-Launched Ballistic Missiles (SLBMs) from six to ten. This class of submarine is also South Korea's proposed model for Canada's submarine program (CPSP).

The Seo Hui is scheduled for delivery to the Navy in 2028, with its launch anticipated in the latter half of this year. In a separate announcement, the Navy named the fifth 3,600-ton class new frigate 'Pyeongtaek,' after the city hosting the Second Fleet Command, emphasizing its strategic importance in defending the West Sea. The Pyeongtaek is expected to be delivered next year.

The excellent military and diplomatic achievements of the great minister Seo Hui and his spirit of overcoming national crises were deemed suitable for the name of a submarine, a core element of maritime defense.
