Navy kicks off long-anticipated push to replace Canada’s beleaguered submarine fleet | CBC News

The move responds to a growing sense of urgency within defence and industry circles about the need to start work on such a project given the age of Canada’s existing submarines and the amount of time needed to design and build such vessels.

“The CAF is establishing a Canadian patrol submarine project to inform timely governmental decision-making about a potential replacement class of submarines, and avoid any gap in submarine capability,” navy spokesperson Lt.-Cmdr. Jordan Holder said.

“In order to enable timely decision-making at some future point regarding a replacement class of submarines and the avoidance of a gap in submarine capability, the CAF required a replacement project to be initiated this year.”

Little time at sea

Yet the decision to move ahead also kick-starts what is expected to be a tough conversation for the navy around the need for new submarines given the high cost of building and operating such vessels, and the many problems that have afflicted its current fleet.

Questions about the costs and benefits of submarines have circulated since Canada bought four second-hand vessels from Britain in 1998. The government at that time argued it was getting a bargain by paying only $750 million for the four Victoria-class vessels.

Yet the vessels have since spent more time in dock for repairs and maintenance than at sea, with Ottawa sinking billions of dollars into the fleet over the past 20-plus years to address a series of problems and incidents including fires and faulty welding.

The most recent incident saw HMCS Corner Brook suffer what may have been permanent damage last year after an errant test damaged the submarine’s main ballast tank. Corner Brook previously ran aground in 2011, while a fire broke out on board in 2019.

The Defence Department has also pegged the cost of maintaining and operating the Victoria-class submarines at around $300 million per year. 

High expenses

A new fleet of submarines may address many of those problems, but Australia’s recent experience suggests building a new fleet won’t be smooth sailing — or cheap.

The Australian government, which has been working for more than a decade to buy 12 French-designed submarines, revealed last year that the diesel-electric vessels will cost more than $80 billion — or more than $6 billion each.

The new cost was nearly double Canberra’s original estimate, and more than the $60 billion Canada plans to pay for a whole new fleet of 15 state-of-the-art frigates to replace its fleet of Halifax-class warships over the next two decades.
