In short: The CCGS Arpatuuq represents a major leap in Canadian maritime capability. Designed to operate year-round in challenging multi-year ice, this vessel is the result of a complex international construction effort. It combines advanced engineering with a specialized design to ensure Canada maintains a persistent presence in the Arctic.

The CCGS Arpatuuq is a significant addition to the Canadian Coast Guard fleet, currently under construction as part of the National Shipbuilding Strategy. The project has a long history, originating from a 2008 announcement by Prime Minister Stephen Harper. After years of procurement shifts and the eventual inclusion of Quebec-based Davie Shipbuilding, the government finalized a C$3.25 billion contract for the vessel in March 2025. This ship is being built through a collaborative international effort, with construction activities spanning Helsinki, Finland, and Quebec, Canada, alongside component assembly in Lithuania.

Technically, the Arpatuuq is a powerhouse. Measuring 138.5 metres in length with a displacement of 22,800 tonnes, it is designed for extreme environments. It holds a Polar Class 2 rating from Lloyd's Register of Shipping, which signifies its capability for year-round operations in moderate multi-year ice. The vessel is powered by a diesel-electric system featuring four 16-cylinder Wärtsilä engines, each producing 9,760 kilowatts. This power drives a triple-screw propulsion setup, allowing the ship to maintain a continuous speed of 3 knots while breaking through 2-metre thick ice.

Beyond its ice-breaking prowess, the Arpatuuq is a versatile platform for Arctic research and emergency response. It includes a helicopter deck and hangar for two aircraft, specialized laboratories, and a moon pool for underwater access. Its operational scope is broad, encompassing cargo transport, oil spill response, and emergency towing. With a capacity to accommodate 100 people, the ship is expected to join the fleet in 2030, marking a critical milestone in Canada's commitment to monitoring and protecting its northern maritime borders.
