Canada picks German consortium for contract to build 12 new submarines

Canada has selected a German consortium led by ThyssenKrupp Marine Systems (TKMS) to build 12 new submarines for the Royal Canadian Navy, Prime Minister Mark Carney announced Monday in connection with a tightly contested procurement that Ottawa said will modernize Canada’s undersea capabilities. The decision ends a competition in which TKMS faced a bid from South Korea’s Hanwha Ocean and frames the acquisition as a step toward deeper integration with NATO operations.

Carney’s announcement follows months of technical and industrial competition in which both bidders offered diesel-electric submarines tailored to Canada’s requirements, with TKMS proposing its 212CD design and Hanwha offering its KSS-III Batch-II submarine, according to reports reviewed in advance of the decision. Officials had previously indicated the government would make a selection by the end of June, and the Monday announcement was tied to Carney’s schedule ahead of a NATO leaders’ summit in Turkey later in the week.

The order marks a shift for Canada’s submarine program, which has relied on older second-hand purchases. Reports on the procurement noted that Canada’s current Victoria-class submarines were acquired from Britain in 1998, and that three of the four vessels are undergoing maintenance, underscoring the pressure to bring new hulls into service. The government’s decision is also positioned as part of Canada’s effort to maintain persistent maritime surveillance in northern approaches.

Both the German and South Korean proposals were described in reports as emphasizing stealth and extended patrol capability, with analysts pointing to how the boats could be used to monitor maritime activity in the Arctic, including routes near the Northwest Passage. One report said the German design was intended to operate in contested areas with minimal detection and to conduct long surveillance missions in key Arctic routes, while another described the South Korean bid as including a larger platform with the potential for greater payload or weapons capacity.

Ottawa’s procurement process, according to reporting before Monday’s announcement, is expected to name a preferred bidder rather than finalize a fully signed contract on the spot. Negotiations with the selected consortium are expected to continue, and additional time may be required to settle terms, including schedule and long-term support and upgrade arrangements, before construction commitments are finalized.

Financial estimates reported for the overall effort have suggested the submarine purchase could be worth tens of billions of dollars when including operations, maintenance and future upgrades, reflecting the scale of Canada’s largest-ever defense acquisition. The procurement has also drawn industrial-policy competition from both bidders, with each side marketing not only technology but also economic benefits for Canada.

With the selection announced, the next phase will be contract talks, design finalization, and planning for how the new submarines will be delivered and integrated into Royal Canadian Navy operations. Officials have indicated the decision was timed to support Canada’s participation in allied security planning in the lead-up to the NATO summit, where member states are expected to review defense readiness and contributions.
