Redundancy is key, and I'll give you an analogy in an area where we've made adjustments. Russia has, for over a decade, actively been jamming, as you probably know, NATO vessels. That is why, until about 2015 or so, the U.S. Navy relied entirely on GPS systems and why the U.S. Navy went back to star navigation, the capability to operate without GPS.
One of the risks that we currently have is a single point of failure if all we do is rely on U.S.-based GPS capabilities. That is why redundancy is important and why multidomain capabilities are important. It's so that, as we do in any other domain of warfare, we never have just one single system on which we are reliant. I'm concerned about the overreliance in Canada on potential single points of failure in space.
