Thank you for your question.
Of course, as our discussion is public, this limits my ability to respond to you somewhat. However, we can tell you that we currently have a submarine detection system. And the technology in this area has evolved on the Russian and Chinese side. These capabilities exist on the east coast and, at present, we expect these capabilities to be present on the west coast. But I'm not an expert on Arctic navigation capabilities. You would have to go to the Canadian Navy.
So we have a detection system. We have proposed that this detection capability from coast to coast as well as in the Arctic be augmented, and that need has been addressed by Brigadier-General Boucher's team.
