Canada's only fully operational submarine departed Halifax Harbour Sunday after another round of mechanical trouble, Maritimes Forces Atlantic confirmed. The mechanical trouble delayed the submarine, which had scheduled a tour for international media on June 20. HMCS Windsor has been docked in Halifax for the last week for repairs to a diesel generator supercharger. Maintenance crews worked around the clock to replace a broken supercharger on HMCS Windsor, readying the submarine to head back out to sea. Only a few months ago, the Windsor cut an exercise short after crew members saw smoke when a battery cell malfunctioned.
