Inside the Seo Hui: A look at Korea's newest submarine

GEOJE, South Gyeongsang Province witnessed a rare sight as reporters ventured into the partially constructed Seo Hui submarine. Donning gloves, they navigated through a narrow passageway barely wide enough for two people. Pipes and machinery remained exposed, with "painting inspection completed" stickers indicating ongoing work.

Hanwha Ocean, the shipyard, provided the media with an unprecedented look at the second Jangbogo-III Batch-II submarine. The submarine's launch is expected in November, though this could adjust based on the Navy's schedule. According to the contract, delivery is slated for December 2027. The Seo Hui, measuring 89 meters in length, is larger than the Dosan Ahn Chang-ho-class submarines of Batch-I.

Its advanced combat management and sonar systems have been enhanced to bolster data processing, target detection, and land attack capabilities, achieving approximately 80% localization. Inside the bow's torpedo room, horizontal launch tubes were arranged.
