You were mentioning that the maritime NORAD will be used to monitor ships, vessels, etc., on the surface.
I'm just asking you about submarines. You also mentioned China as a rising power, blue-fleet submarines. Going a little bit south of Bering Strait we arrive in the Pacific area where China is flexing its muscles in the Scarborough shoal, claiming islands in Japan, and building a significant submarine fleet.
We saw from experience in the Second World War that a U-boat came, and they were fixed on the St. Lawrence River right in the Atlantic. Now this is 60 or 70 years later.
Canada has one submarine on the Pacific coast on active duty. I don't know how many the Americans have, but the Chinese have 70.
How will maritime NORAD be capable of monitoring these creatures under the sea? I understand that you can monitor what is up on the surface. You can monitor the movements. But under the sea is a completely new story, a new element.
I know the United States has the key vote towards changing the interests of the people of the south, of the Pacific, but what does submarine warfare, let's say, bring to the equation in terms of threats?
