ANKARA, Turkey — Canada has crowned Germany’s ThyssenKrupp Marine Systems (TKMS) as the preferred bidder to replace the Royal Canadian Navy’s four Victoria-class submarines with a fleet of “up to” a dozen Type 212CD submarines.

The long-awaited decision was announced today by Canadian Prime Minister Mark Carney during a pit stop in Halifax, Nova Scotia, on his way to the NATO Summit in Ankara.

“The submarine is proven and capable, and is widely used by our allies,” he said. “The type we’re moving to purchase, the type 212CD … will operate seamlessly along our NATO partners.”

Carney declined to reveal the estimated cost of the program, citing ongoing negotiations, but said it would be the largest defense procurement in Canadian history. The Globe and Mail estimated the contract would likely be worth between $20 billion and $30 billion.
