HMCS Windsor is returning Tuesday from her deployment to the Norwegian Sea (part of Exercise Dynamic Mongoose 2016).
The submarine will arrive at Her Majesty’s Canadian Dockyard Halifax in the afternoon.
After some technical problems, HMCS Windsor joined Exercise Dynamic Mongoose 2016, a NATO anti-submarine warfare exercise.
Some 3,000 sailors and aircrew from eight countries, including Canada, France, Germany, Norway, Spain, Turkey, the United Kingdom and the United States, participated in the exercise.
During the exercise, the submarines traveled from one location to another while surface vessels try to track them down and simulate an attack, according to the Royal Canadian Navy. The surface units also traveled between two transit points while under the threat of submarines.
