South Korea Plans To Launch First Domestically Built Nuclear-Powered Submarine By Mid-2030s

South Korea has officially announced plans to launch its first domestically built nuclear-powered submarine by the mid-2030s, a strategic initiative confirmed by Defence Minister Ahn Gyu-back during a high-level defence meeting led by President Lee Jae Myung. This ambitious project aims to bolster the nation's naval capabilities and maritime security in the Indo-Pacific region. By leveraging advanced indigenous engineering, South Korea seeks to reduce reliance on foreign technology while enhancing the operational endurance of its underwater fleet against evolving regional threats.

The deployment of nuclear-powered vessels necessitates strict adherence to the IMO’s Code of Safety for Nuclear Merchant Ships and relevant SOLAS Chapter VIII requirements, which govern the design, construction, and operation of nuclear-propelled craft. Compliance departments must ensure that these submarines meet the rigorous safety standards outlined in the International Convention for the Safety of Life at Sea. Furthermore, integration with MARPOL Annex VI regulations regarding emissions and waste management remains critical, as nuclear propulsion systems require specialized classification society oversight to maintain global maritime safety protocols.

This shift toward nuclear-powered naval assets will significantly impact the professional requirements for chief engineers and second engineers. These technical officers must undergo specialized training in nuclear reactor operations, radiation safety, and advanced thermal management systems. Mastery of these complex propulsion plants is essential for maintaining vessel readiness. Consequently, engineering personnel should prioritize certifications in nuclear-marine engineering to remain competitive and qualified for future roles within this sophisticated segment of the domestic maritime industry.
