Thank you, Mr. Chair.
Commodore Sing, my question ties in with the answer you just provided.
Let's look at the situation from strategic, operational and tactical standpoints. Last week, my colleague Cheryl Galland and I had an opportunity to spend 24 hours on a mission in a Canadian submarine. We carried out an intervention and procedures by attacking one of our frigates. We also spent two days obtaining information on the various systems. I also saw our future offshore vessels currently being built in the Irving shipyard. I understand that those vessels will not really be armed, that they will rather be used to patrol, to exercise an influence over the territory and to ensure Canada's presence in the Arctic waters.
For naval forces, I think the most formidable weapon is the submarine because it is difficult to detect. In addition, a torpedo will sink anything you want. Should we not be thinking more about increasing our submarine capacity? It's a fact that frigates have Sparrow missiles, but a Canadian frigate is not difficult to destroy, and a foreign aircraft can easily bomb it. However, the submarine is truly a formidable weapon.
From a strategic point of view, for Canada's defence, do you think that we should rather invest in submarines? If so, how many of them?
