The South Korean project to build a nuclear-powered submarine, known as the 'Jangbogo N Project,' has been exempted from a feasibility study, which is expected to accelerate its progress.


On November 6, the Defense Acquisition Program Administration (DAPA) announced that it had reviewed and approved the basic strategy for the Jangbogo N (KSS-III Batch-III) project during the 179th Defense Acquisition Promotion Committee meeting.


Typically, feasibility studies take one to two years, so this exemption allows for the project to commence next year, with plans for operational deployment in the late 2030s. However, a separate in-depth review process will still take place.


The selection of the contractor for the submarine construction will be conducted through a competitive bidding process. DAPA previously determined that domestic shipbuilders have reached a sufficient level of capability in submarine design and construction, opting for competition rather than a direct contract. However, the government will directly develop and secure the submarine's power source, the small modular reactor (SMR), and some key missiles, providing them to the prime contractor.


DAPA emphasized that the nuclear submarines acquired through this project will enhance deterrence against security threats from North Korea's nuclear and missile capabilities and contribute to strengthening South Korea's self-defense capabilities, including the implementation of an underwater kill chain.
