VICTORIA -- Hundreds of sailors from five Canadian warships have been quarantining in Victoria, B.C. hotel rooms in preparation for large-scale war games next week alongside the United States Navy. Approximately 800 personnel from both sides of the border will participate in Task Group Exercise (TGEX) 21-01 off Vancouver Island. The exercise is scheduled for 12 days, starting Monday, and will feature a simulated airborne drone attack repelled by four shipborne missiles. The exercise also signals the return to regular operations for submarine HMCS Victoria, which has undergone extensive maintenance and upgrades since its last outing in 2015. Once fully operational, the sub will “provide a consistent submarine presence in our coastal waters and the western maritime approaches to Canada,” according to Canadian Submarine Force commander Capt. Jean Stéphane Oullet, who is currently aboard the Victoria.
