Seoul: South Korea was set to hold a launch ceremony for its first 3,600-ton-class naval submarine Wednesday, according to the Navy and the arms procurement agency. This move aims to enhance the country's underwater deterrence capabilities against North Korean threats.
According to Yonhap News Agency, the ceremony for the first of three Changbogo-III Batch-II class submarines will take place at shipbuilder Hanwha Ocean's dockyard in Geoje, approximately 330 kilometers southeast of Seoul. Named after the Joseon Dynasty engineer Jang Yeong-sil, the 89-meter-long Batch-II submarine is part of South Korea's KSS-III program to acquire advanced diesel-electric attack submarines.
The Navy and the Defense Acquisition Program Administration (DAPA) highlighted that the ROKS Jang Yeong-sil, as the Navy's first 3,600-ton-class submarine, is a world-class diesel submarine and a core strategic asset with enhanced capabilities to address various maritime threats. Officials noted that compared to the 3,000-ton Batch-I class submarines, the new model is larger and features upgraded detection and strike capabilities, allowing it to remain stealthy for longer periods.
The submarine's combat and sonar systems have been improved for better information processing and target detection, while lithium-ion batteries enable extended underwater operation and faster movement. Sound absorption technologies have been integrated to enhance covertness, and more homegrown equipment has been utilized to ensure stable operations.
The new submarine is expected to feature 10 vertical launch tubes for submarine-launched ballistic missiles, an increase from the six tubes on the 3,000-ton Batch-I submarines. It is anticipated to play a significant role in South Korea's maritime three-axis deterrence system, including the Kill Chain preemptive strike platform aimed at neutralizing key North Korean nuclear and missile targets upon signs of imminent threat.
The submarine is scheduled for delivery to the Navy by the end of 2027, with the construction of the other two 3,600-ton-class submarines currently underway.
