it is the ROYAL navy
kind of an old story, but there are many updates.
>In 2004, HMCS Chicoutimi caught fire during its maiden voyage as a Canadian sub. Nine members of the crew suffered smoke inhalation. Lt. Chris Saunders, 32, died.
>HMCS Corner Brook ran aground in 2011 and is not expected back in service for at least two years.
>HMCS Windsor started a two-year refit in 2007 and is still not ready for service. It remains dry-docked in Halifax.
>The subs had problems even before they were sold to Canada. One of them had its torpedo doors welded shut because of flooding.
>Canada's navy has not said what the refit cost, but documents show that $17 million was budgeted in 2010. The real cost for the Windsor that year alone was $47 million. It is not known how much has been spent in total on the four subs.
"I'm appalled we've done a dumb deal with an ally like this," Hancock said. "If this was the Americans, we'd say good luck and serves you right. But as it's Canada, I think there are a lot of questions to be answered."
