A South Korean navy submarine has embarked on an unprecedented 14,000-kilometer voyage to Canadian waters, arriving just as Canada prepares to announce the winner of a multi-billion dollar submarine acquisition competition. The Republic of Korea Navy's Dosan Ahn Changho submarine set sail from Jinhae Naval Base on March 25 and is scheduled to participate in joint naval exercises with Canada in June, highlighting the growing maritime partnership between the two nations.
Submarine Competition Nears Final Decision
Canada's Royal Canadian Navy is preparing to acquire up to 12 new submarines, with the competition narrowed down to two leading contenders. The KSS-III submarine from South Korea's Hanwha Ocean is competing against Germany's Type 212CD submarine from ThyssenKrupp Marine Systems (TKMS). The Liberal government anticipates announcing the winning bid by summer 2026, making the timing of the South Korean submarine's visit particularly significant.
Record-Breaking Voyage Demonstrates Capabilities
South Korean naval officials emphasize that this 14,000-kilometer journey represents the longest voyage ever undertaken by one of their submarines. This demonstration of long-endurance operational capability serves as a strategic showcase to Canadian defense officials evaluating submarine performance and reliability. The submarine is expected to arrive in Victoria, British Columbia, in late May after its trans-Pacific journey.
Joint Exercises and Personnel Exchange
Department of National Defence spokesperson Andrée-Anne Poulin confirmed that the visit and exercises will occur from May 23 to June 2. The South Korean submarine will be accompanied by a frigate and will conduct combined anti-submarine warfare exercises with Royal Canadian Navy vessels and Royal Canadian Air Force maritime patrol aircraft. Additionally, two Royal Canadian Navy submariners will join the South Korean submarine crew in Hawaii as part of the REGULUS exchange program, designed to develop skilled sailors through exposure to different operational environments and tactics.
Strategic Partnership and Industrial Benefits
"The Republic of Korea Navy's port visit to Esquimalt and subsequent joint exercises with the Royal Canadian Navy demonstrate a strong and growing maritime partnership, reinforcing shared commitments to regional stability and interoperability," Poulin stated in an email. Beyond military cooperation, industrial benefits represent a crucial factor in the submarine competition. Both Hanwha Ocean and TKMS have established multiple alliances with Canadian companies as part of their bids, promising significant economic and technological benefits to Canada's defense industry.
Technical Capabilities and Political Considerations
Senior Royal Canadian Navy officers have concluded that both the German and South Korean submarines meet the navy's demanding requirements. Prime Minister Mark Carney acknowledged in September 2025 that "both of them fulfil the requirements, the very high requirements for the Canadian Navy." The decision will ultimately balance technical specifications, industrial benefits, and strategic partnerships, with the South Korean submarine's current visit providing a tangible demonstration of operational capabilities just before the anticipated announcement.
