Canada's continental-defence corvette: range, armament and an ice-rated hull

What is the assessment of Canada's proposed continental-defence corvette?

The 7,000-nautical-mile range and Halifax-like armament are considered sensible for Canada, but point toward a frigate-sized vessel. An ice-rated Type 31-derived hull or a custom design is suggested.

The requested range of 7,000 nautical miles and Halifax-like weapons point toward a frigate-sized vessel. Canada needs long endurance, so a ship with limited range would not satisfy the role. Finnish ships are compared against the requirement using a cited range of around 3,000 nautical miles and a different weapons fit. A Type 31-sized design is considered a plausible starting point. A custom build is the alternative because the exact combination is not regarded as readily available off the shelf. Canada's need for an ice-rated hull also distinguishes its requirements from the French case and complicates comparison with the European Patrol Corvette.
