The Halifax-based HMCS William Hall is en route to the Arctic to take part in Operation Nanook.
The ship has deployed on a two-month mission that will see it work alongside forces from Denmark, France and Germany, as well as other assets of the Canadian Armed Forces.
As part of the operation, HMCS William Hall will sail through the Northwest Passage and visit Rankin Inlet, Nvt., reinforcing Canada’s presence in the north.
The operation takes place annually across Yukon, the Northwest Territories, Nunavut and Labrador, with up to five deployments throughout the year. One of the key focuses is to conduct surveillance in the north, while working with Allies.
There are several versions of the operation now, which first began in 2007.
“At its core, Op NANOOK strengthens the Canadian Armed Forces’ knowledge of this vital region, allows us to work hand-in-hand with our fellow Arctic nations and key Allies, and fortifies our close partnerships with federal, territorial, and local communities,” the government’s website notes.
Built in Halifax as part of the Arctic and Offshore Patrol Vessel program, HMCS William Hall was commissioned into service in May of last year.
