In a pivotal moment for Canadian defence policy, South Korea and Germany are intensifying their bids for a substantial contract to supply Canada with a fleet of 12 submarines. With Prime Minister Mark Carney signalling a decision by late June 2026, this procurement represents one of the largest military investments in Canadian history. The estimated value of the contract could reach between $60 billion to $120 billion over the submarines’ operational lifespan, including an initial acquisition cost of $24 billion to $30 billion.
The Bidders: Hanwha Ocean vs. TKMS
The competition has narrowed to two prominent contenders: South Korea’s Hanwha Ocean, offering the KSS-III Batch-II submarine, and Germany’s ThyssenKrupp Marine Systems (TKMS), presenting the 212CD submarine as part of a joint German-Norwegian initiative. Both vessels are diesel-electric submarines, reflecting modern technological advancements in naval warfare.
The South Korean navy’s Dosan Ahn Changho submarine has been making headlines as it embarks on a significant journey from Jinhae Naval Base, having set sail on March 25. It is scheduled to dock at Canadian Forces Base Esquimalt in late May, where it will participate in a joint naval exercise with the Royal Canadian Navy in June. This strategic display not only showcases the capabilities of the KSS-III submarine but also serves as a testament to South Korea’s commitment to strengthening ties with Canada.
Economic and Strategic Implications
Prime Minister Carney’s decision will be influenced by more than just military specifications. With Canada seeking to diversify its trade relations amidst a challenging economic landscape, the submarine procurement is viewed as a crucial step in reducing reliance on the United States. The enduring partnership that will emerge from this contract, spanning nearly 70 years, underscores the significance of the decision—both for national security and international relations.

In response to the competitive climate, the Canadian government recently extended the bidding timeline to allow both bidders to enhance their proposals. Hanwha Ocean has reportedly increased its economic benefits pledge to $70 billion, promising to establish production facilities for military vehicles within Canada, utilising local resources and workforce. In contrast, TKMS has emphasised its collaborative agreements with Canadian firms, including Bombardier Inc., to support Canada’s long-term defence capabilities.
Upcoming Diplomatic Engagements
As the bidding process unfolds, diplomatic engagements are expected to amplify. German Defence Minister Boris Pistorius is set to visit Canada during the CANSEC defence trade show in late May, following a recent trip by Vice-Chancellor Lars Klingbeil. This strategic outreach reflects Germany’s commitment to securing the submarine contract, attempting to underscore the strengths of the TKMS proposal.
Meanwhile, South Korea is preparing to send a high-level delegation to further solidify its economic relationship with Canada, potentially featuring key officials from President Lee Jae Myung’s administration. This concerted effort highlights the importance both countries place on this contract, which could redefine their military and economic landscapes.
Why it Matters
The outcome of Canada’s submarine procurement will not only reshape the Royal Canadian Navy’s capabilities but also serve as a barometer for the nation’s foreign policy direction. With the potential for long-term economic benefits and enhanced defence infrastructure, the stakes are high. This contract could catalyse a significant shift in Canada’s military presence on the global stage, marking a departure from decades of underinvestment in naval capabilities. As both bidders ramp up their efforts, the implications of this decision will resonate far beyond the waters off Canada’s coasts, influencing international relations and defence strategies for years to come.
