Harry DeWolf-class offshore patrol vessels are warships of the Royal Canadian Navy (RCN) built within the Government of Canada Arctic and Offshore Patrol Ship (AOPS) procurement project, part of the National Shipbuilding Strategy. In July 2007 the federal government announced plans for acquiring six to eight icebreaking warships for the RCN.
The vessels are modelled on the Norwegian Coast Guard NoCGV Svalbard and as of 2007 were projected to cost CA$3.5 billion to construct with a total project procurement budgeted to cost $4.3 billion in order to cover maintenance over the 25-year lifespan of the vessels. In 2018 it was reported that the cost of the first six ships had increased by $810 million over previous projections. In 2023 it was reported that the cost for the first six ships had increased by a further $780 million and that of the two envisaged vessels for the Coast Guard by an additional $100 million.
