South Korean Submarine Makes Historic Trans-Pacific Voyage to Canada
Introduction
The arrival of the Republic of Korea Navy’s KSS-III submarine, ROKS Dosan Ahn Changho, at Canadian Forces Base Esquimalt in Victoria, British Columbia, marks a significant milestone. This event signifies the first trans-Pacific journey ever completed by a South Korean submarine, extending its operational reach and bolstering international naval cooperation.
A Milestone Voyage Across the Pacific
The KSS-III class submarine, ROKS Dosan Ahn Changho, has successfully concluded an unprecedented voyage, arriving at Canadian Forces Base Esquimalt on May 23rd. This journey represents the longest deployment ever undertaken by a submarine of the Republic of Korea Navy (ROKN). The 3,000-ton-class vessel navigated an impressive distance of approximately 14,000 kilometers, departing from Jinhae Naval Base in South Korea and making its way across the vast Pacific Ocean, with strategic stops in Guam and Hawaii before reaching its Canadian destination.
Joint Training and Submarine Observation
Departing Jinhae on March 25th, ROKS Dosan Ahn Changho embarked on its mission to participate in planned naval cooperation activities and combined training exercises with the Royal Canadian Navy (RCN). During this extensive trans-Pacific deployment, the submarine made essential logistical stops in Guam and Hawaii. A particularly noteworthy aspect of the journey was the embarkation of two Royal Canadian Navy submariners for the final leg from Hawaii to Victoria. This provided Canadian personnel with an invaluable opportunity to observe the KSS-III’s advanced operations firsthand at sea, fostering mutual understanding and capability assessment.
Positive Feedback from Canadian Observers
One of the Royal Canadian Navy submariners who had the opportunity to serve aboard the state-of-the-art vessel shared highly positive impressions. Describing the experience, the submariner noted the advanced technology and design of the KSS-III, stating, “Being on a state-of-the-art submarine like this has really shown us that we have a great future ahead. It’s not going to be a steep learning curve. It’s going to be a very easy transition. Everything felt so familiar.” This sentiment highlights the user-friendliness and advanced, yet intuitive, design of the South Korean submarine, suggesting a smooth potential integration for future collaborations.
Demonstrating Interoperability and Extended Reach
En route to Canada, ROKS Dosan Ahn Changho successfully demonstrated advanced communications interoperability with the Royal Canadian Navy. On May 18th, the submarine established communication with Maritime Forces Pacific using its onboard combined C4I (Command, Control, Communications, Computers, and Intelligence) system. This achievement marked a significant first, as it was the initial instance of a South Korean-built submarine communicating with Canada’s Pacific naval command via a shared C4I system. This capability underscores the ROK Navy’s growing ability to extend its command-and-control network beyond traditional alliances, engaging effectively with key international partners.
Naval Honors and Strategic Significance
The arrival in Esquimalt was further underscored by the presence of the ROK Navy frigate ROKS Daejeon, a 3,100-ton-class Daegu-class frigate, which accompanied ROKS Dosan Ahn Changho. Upon docking, the crews of both vessels, ROKS Dosan Ahn Changho (SS-083) and ROKS Daejeon (FFG-823), rendered formal naval honors to distinguished Canadian and South Korean officials, including the commander of Canada’s Pacific naval forces and the South Korean ambassador to Canada. This historic visit carries substantial operational and strategic weight, showcasing the long-range endurance of South Korea’s indigenously developed submarine capabilities and presenting the KSS-III platform in a demanding blue-water operational context.
High-Level Naval Dialogue and Future Cooperation
The submarine’s deployment was complemented by significant high-level naval discussions in Ottawa. On May 22nd, ROK Navy Chief of Naval Operations Admiral Kim Kyung-ryul met with Vice-Admiral Angus Topshee, Commander of the Royal Canadian Navy and incoming Vice Chief of the Defence Staff. Their discussions focused on enhancing military cooperation and fostering defense-industrial collaboration between the two nations. The ROK Navy reported that specific practical measures, including the expansion of combined exercises and personnel exchange programs, were thoroughly explored.
Canada’s Submarine Program and Korean Competition
This visit also aligns with Canada’s ongoing efforts under the Canadian Patrol Submarine Project (CPSP), a critical initiative aimed at replacing the Royal Canadian Navy’s aging Victoria-class submarines. Team Korea, comprised of Hanwha Ocean and HD Hyundai Heavy Industries, has put forth the KSS-III design as a contender for Canada’s future submarine requirement, facing competition from Germany’s ThyssenKrupp Marine Systems Type 212CD. The Korean bid is backed by substantial government-level support, including proposals for industrial and technological cooperation, long-term sustainment, and broader defense-industrial partnerships.
Strengthening Industrial Ties in Canada
Hanwha Ocean has actively pursued the industrial dimension of Team Korea’s CPSP campaign by forging strategic partnerships with Canadian shipbuilding, technology, and academic institutions. Earlier in the year, the company formalized agreements with Ontario Shipyards and Mohawk College to bolster shipbuilding capabilities and support workforce development. Further teaming agreements and university Memoranda of Understanding have since been announced, signaling a commitment to integrating Canadian companies and researchers into its global submarine supply chain.
Continued Engagement and Future Endeavors
The port visit to Esquimalt, scheduled from May 23rd to June 2nd, facilitated continued engagement between the ROK and Canadian navies. During this period, ROKS Dosan Ahn Changho and ROKS Daejeon were scheduled to participate in professional exchanges and various other activities with the Royal Canadian Navy. Following its engagements in Canada, ROKS Dosan Ahn Changho is expected to proceed to Hawaii to participate in the U.S.-led RIMPAC 2026 exercise before its eventual return to South Korea.
Conclusion
The historic trans-Pacific voyage of the ROKS Dosan Ahn Changho to Canada marks a new era of naval capability and international partnership for the Republic of Korea Navy. This deployment not only demonstrated the advanced technological prowess of the KSS-III submarine but also solidified the growing strategic ties between South Korea and Canada, paving the way for future collaborative ventures and enhanced regional security.
