2 weapons

Irving Shipbuilding operates the Halifax Shipyard and related Nova Scotia facilities that cut, fabricate, assemble, repair, and support Canadian naval ships. The company says Halifax Shipyard has built six Arctic and Offshore Patrol Ships for the Royal Canadian Navy, is building two AOPS variants for the Canadian Coast Guard, and is shifting production capacity toward the River-class destroyer program.

The manufacturer's public role is tightly linked to the National Shipbuilding Strategy. Canada selected Irving Shipbuilding in 2011 for the combat work package, then used long-term umbrella agreements and project contracts to move from shipyard modernization into AOPS delivery and River-class destroyer construction. Its facilities include a large covered Assembly and Module Hall on Halifax Harbour, Marine Fabricators in Dartmouth for steel preparation, Woodside Industries for supplemental fabrication, and the Bluenose Building for engineering and design work.
