Some Canadian shipbuilders are concerned a German design could be the leading contender to replace the navy's aging sea support ships.
Replenishment ships, like the Preserver and the Protecteur, help the Canadian navy stay at sea for long periods of time, but at 40 years old, they'll soon need replacements.
Sources have told the CBC that a German-designed ship called the Berlin class could win the $3-billion contract.
Since the Second World War, Canada has designed and built its own warships. However, in recent years, the German industry has lobbied the Canadian government to supply designs for frigates, destroyers and new submarines.
