Canada picks Germany’s TKMS for major submarine fleet deal

Canada picks Germany’s TKMS for major submarine fleet deal

Canada has selected Germany’s ThyssenKrupp Marine Systems (TKMS) as the preferred supplier for Canada’s next submarine fleet—up to 12 boats—beating South Korea’s Hanwha Ocean. The move matters because it reshapes Canada’s maritime security posture, ties the program closer to NATO partners, and kicks off negotiations for what Canada called its biggest-ever defence procurement.

Key Takeaways

What exactly did Canada award Germany—and what happens next?

Canada awarded Germany a major submarine contract by selecting TKMS as the preferred supplier for Canada’s Patrol Submarine Project, Prime Minister Mark Carney said, according to DW. Carney said Canada will now enter negotiations to procure up to a dozen submarines.

DW said the value was not immediately disclosed by Canada or TKMS, but reported that Germany’s DPA estimated the submarines and related support could be worth about €20 billion. The Guardian described it as a multibillion-dollar deal and said the broader lifetime cost could be far higher once decades of maintenance are included.

Why did this submarine decision make headlines beyond Canada?

The announcement landed just as defence spending and alliance commitments were expected to dominate a NATO leaders’ summit in Ankara, DW reported. German Defence Minister Boris Pistorius called the decision a milestone for transatlantic security and said it would become a key pillar in NATO’s North Atlantic and Arctic strategy, according to DW.

Canada’s Defence Minister David McGuinty said the decision provides the Royal Canadian Navy with a “critical capability” to defend and secure Canada’s coastline, DW reported. The Guardian also framed the purchase as deepening Canada’s NATO ties after a competitive bidding war.

Why did Hanwha Ocean’s shares drop after losing the submarine bid?

CNBC reported that Hanwha Ocean shares fell about 23% after it lost its bid to build Canada’s next fleet of submarines to TKMS. The outlet said Carney announced TKMS as the preferred supplier and highlighted that the 212CD platform is shared by Germany and Norway—two of Canada’s closest allies.

CNBC also noted TKMS said the announcement marked a new chapter in defence cooperation among close NATO allies. Canada still designated Hanwha Ocean as a reserve supplier if negotiations with TKMS fail, per DW’s reporting that TKMS beat out Hanwha for the contract.

How big is the program, and what does Canada get?

The Guardian reported Canada plans to buy 12 “hi-tech” German submarines, marking the first time Canada has bought brand-new vessels. It said Canada’s current four Victoria-class submarines were bought secondhand from the UK in 1998, and that most were undergoing maintenance.

In its account of the competition, the Guardian said Canada had indicated both firms’ diesel-electric offerings suited its military needs: TKMS’ 212CD model and Hanwha’s KSS-III Batch-II. The newspaper said the order could help Canada operate more effectively in contested areas, including the Northwest Passage.
