Thank you. Another great and complex question.
I'm conscious that I'm probably taking too long to answer some of these questions, and I apologize, but clearly it's a subject that interests me and I want to make sure that I can be as clear as possible.
Let me talk about four domains of space: the way it supports operations in terms of communications, the way it supports operations in terms of awareness, the way it gives us awareness of a threat, and the threats that are posed in space.
Let me start by saying that we are very conscious of the Canadian interest in preventing the weaponization of space, and we continue to work very carefully to support that policy of the Government of Canada. As well, the Government of Canada has an interest in space that goes beyond the Canadian Forces, and we work very closely with the Canadian Space Agency and other government departments to manage the government interest in that domain.
From a Canadian Forces perspective, one of our principal uses of space, historically, is to provide communications. Using satellite communications is in fact an excellent way of getting the high-speed, high data rate communications that we need for our modern command and control systems. We invest where we can in that. Historically, we've rented satellites in order to do that for us, and it tends to be quite expensive and you tend to pay by the volume of information. We partner where we can with allied communications systems, but it has historically been insufficient to meet all of our needs. We continue to look for ways to invest in secure, guaranteed, high data rate communications, and spend less money on it because it tends to be quite expensive. There are a couple of initiatives we're pursuing that you may have heard about, which represent cost avoidance in the future, at a fraction of the cost today, by making investments today in that type of capability.
In terms of awareness, we use RADARSAT quite a lot, we use weather satellites, and we use other types of satellites available through allies to increase our awareness of what's going on. That's a very important component of our use of space, because in terms of intelligence surveillance and response and in terms of just being able to understand the domains we're going into, we rely heavily on space instruments to do that for us. We have a number of different programs and a number of different mechanisms for doing that.
In terms of the threat in space, we need a degree of awareness of what is going on in space because quite often space can be used as a domain within which weapons travel that can be a threat to Canada. So an awareness of what's going on in space is very important. As well, space debris has posed problems for us historically, and we're enhancing our ability to understand what type of space debris may be posing a threat to Canada and to predict as best we can—although it is a hugely inexact science—the threat that it may pose to us, so that we can respond to it appropriately.
Finally, there is a threat in space, and we have seen it develop. We have seen weapons testing, and it would be, I think, self-evident that countries would wish to deny potential adversaries the use of space in a conflict. There is work going on in that domain, and we track it carefully. We have to understand the vulnerability of our own space sensors and certainly of allied space sensors, and we work to try make them as robust as we can. But a satellite is a pretty vulnerable piece of kit up in space.
