Canada's only currently seaworthy submarine, HMCS Corner Brook, has sunk the retired USS Mobile Bay off Hawaii, according to reports emerging just days after Ottawa said only one of the country's four submarines was fit for service.
The timing has drawn attention because the federal government had recently acknowledged the limited readiness of Canada's submarine fleet. That made HMCS Corner Brook the sole operational boat at the moment, putting extra focus on any mission it undertakes.
The ship that went down was a retired U.S. warship, not an active frontline vessel. Its sinking off Hawaii therefore appears tied to the use of a decommissioned target rather than a combat incident, though the available details remain limited in the trimmed report.
Even so, the event underscores a contrast in Canada's naval picture: while one submarine was able to carry out a high-profile operation, the broader fleet's condition remains under scrutiny. With only one boat described as seaworthy, questions about maintenance, modernization and long-term submarine readiness are likely to continue.
