I think there are a couple of ways to answer this, and perhaps Dr. Hickey can elaborate or has a different view.
In my view, the challenges of hypersonics, given the threat actors that we face such as the Russian Federation and China, mean that it will be very difficult for us to do this alone. If we look at how the U.S. government is starting to develop its golden dome system, they are looking at multiple layers of sensors and capabilities at different orbital heights. A large portion of this is space-based, but there's not just that; there are also ground-based and sea-based systems.
The core part of that system is the development of new AI programs, which are basically taking synergistically all of this data and sifting through, developing a much more in-depth situational awareness that can allow us to deal with some of the inherent challenges, which Dr. Hickey outlined with the hypersonic systems, that make them much more difficult to detect than traditional ICBMs or other systems. They bring all that data in to provide a better ability to detect and target these systems with potentially new space-based, ground-based or air-based interceptors. To some degree in a NORAD context and in light of the negotiations that are potentially occurring right now in Washington, our response to this area would have to work with the United States given just the amount of assets they are willing to put into this problem set and maybe complement it or work through that system in order to provide a much more effective defence in this area.
