We've been operating in the north for generations, back to the Terror and the Erebus. They have given us that.... We found wreckage from the 1800s. We've continued that exploration and have worked in the north for generations.
In terms of capabilities, heavy icebreakers are key. I think you've seen an investment in the Coast Guard. At the same time, you've seen a significant investment in the Royal Canadian Navy. We've now brought online three Arctic and offshore patrol ships that work in the north. In terms of that capability, the Coast Guard is recapitalizing itself, and these vessels do not operate in isolation. If you visit an Arctic and offshore patrol ship, you'll see that the vessel is designed to operate in the north in first-year ice.
At the same time, it's also designed to have our government partners on board. We have research and development on board. We can carry Transport Canada folks and folks from border services, as well as from Immigration and from Environment. Those are whole-of-government platforms to enforce the sovereignty of Canada in the north, and they are perfect platforms for that piece. They can operate throughout a larger percentage of the ice year than most ships.
