Halifax Shipyard Delivers HMCS Harry DeWolf, Lead Vessel in Canada’s New Arctic and Offshore Patrol Vessel Class


(Halifax, NS) – Today at CFB Halifax Dockyard, Irving Shipbuilding Inc. officially delivered the HCMS Harry DeWolf, Hull Number 430 and the lead vessel in Canada’s new Arctic and Offshore Patrol Vessel class, to Canada and the Royal Canadian Navy. The Arctic and Offshore Patrol Vessel Class will be known as the Harry DeWolf Class. The HMCS Harry DeWolf was built by Canadian shipbuilders in the most modern and largest indoor shipbuilding facility in North America.


The vessel was moved this morning from Halifax Shipyard to the CFB Halifax Dockyard, where it will be based. An official Acceptance Ceremony was held on the Dockyard NJ Jetty, where ownership of the vessel was signed over to Canada and the Royal Canadian Navy. Mr. Kevin McCoy, President of Irving Shipbuilding, signed on behalf of the 2,000 shipbuilders at Irving Shipbuilding. On the instruction of Vice Admiral Art MacDonald, who signed the Acceptance on behalf of Canada, the ship’s company then marched on board to assume command of the vessel.


The 6,615 tonne HMCS Harry DeWolf is comprised of 440,000 parts and is the most modern and the largest vessel ever built in Canada in a combat package. It is also the largest Navy vessel built in Canada in more than 50 years. Other characteristics include:


  • Length: 103.6 metres
  • Beam: 19.0 metres
  • Speed (open water): 17 knots
  • Complement: 65 crew + 20 embarked forces
  • Endurance: 120 days
  • Range: 6,800 nautical miles at 14 knots
  • Integrated diesel-electric power and propulsion
  • Bow thruster for manoeuvering and berthing without tug assistance
  • Enclosed Fo’c’sle/Cable deck to protect foredeck machinery and personnel from harsh Arctic environment
  • Retractable active fin stabilizers for roll reduction
  • Ability to operate and hangar a CH-148 Cyclone or small utility helicopter


The HMCS Harry DeWolf is the first of six Arctic and Offshore Patrol Vessels for the Royal Canadian Navy, with the next three already under construction: the future HMCS Margaret Brooke was launched in November 2019 launched and continues construction in the water at Halifax Shipyard, the future HMCS Max Bernays is in the Assembly Hall at Halifax Shipyard preparing for a move to land later this year, while the future HMCS William Hall entered the Assembly Hall last November and will soon have the keel laying. First steel on the fifth Arctic and Offshore Patrol Vessel will be cut in the coming months.


HMCS Harry DeWolf was launched on September 8, 2018, completed successful Builder’s Trials at sea in November 2019, then completed a series of Sea Trials (also known as ‘Acceptance Trials’) earlier this month, followed by crew training for the members of the Royal Canadian Navy who will comprise the ship’s company.


The formal Commissioning Ceremony for HMCS Harry DeWolf is scheduled to take place in 2021.
