Thank you very much for that question.
It, in fact, grows from the earlier discussion about the role of the Coast Guard, in the sense that when we look at intelligence collection and surveillance and the distribution of information, this is a vital defence issue, which complements and enhances the Royal Canadian Navy's capabilities. We can say that without any military training—further to the earlier question that was put forward about NATO requirements—in fact the Coast Guard has a major role to play.
The Russians have a petro-economy: 42% of their economy is related to gas and oil extraction, almost all of it in the northern flank of Siberia, in Novaya Zemlya, in the Kara peninsula and elsewhere. They have spent enormous sums of money, despite the war in Ukraine, on the enhancement of their ports and surveillance in the north, buttressed, as I mentioned earlier, by the 40-plus icebreakers, of which seven are nuclear-driven.
Further to your question, I would suggest that the Coast Guard has the most intimate relationship with northern communities. Leaving aside physical sensors, whether by surveillance satellites or undersea means, the Coast Guard provides an enormous entree into this vast world. It is truly colossal, the space that's involved to monitor. That relationship, built over many decades, is absolutely unparalleled and one that the navy benefits from enormously by virtue of its current relationship with the Coast Guard.
When it comes to sensors—whether it's what Coast Guard crews see, what is garnered from overflights or what is selected from drone surveillance—the Coast Guard can play an enormously important role in terms of enhancing our broader understanding of what's going on in the north.
