Thank you very much, Mr. Chair. Those are very pertinent questions.
I talked about domain awareness. We want to ensure we know what's going on within our sovereign territory, waters and airspace. Making sure we have domain awareness above the sea, on the sea and below the sea is a key tenet of ensuring that within NORAD modernization, as well.
I believe you heard from the commander of the navy with respect to under-ice capability. I won't repeat that testimony from a few weeks ago.
The fact is that we want to ensure we have domain awareness of our allied submarines, as well as potential adversaries in the region. Just to be clear, we do have that. Given the sensitivities of the submarine waterspace management, I'm probably not going to go into detail. We conduct co-operative waterspace management with our closest ally, the U.S., given the fact that we have submarines on both coasts and they have submarines on both coasts. We conduct this co-operative waterspace management, which allows us to be certain about which boats are in the water in all our territorial seas and adjacent waters.
