Like a number of our allies, we operate diesel submarines. We've been in discussion with our allies for many years over the performance of our submarines and where we want to go in the future. A number of countries are looking at their potential options going into the future. Australia has recently decided, and we're being informed by that.
In the meantime, I think our greater perspective is that we still have some very good use left in the Victoria class. We plan on demonstrating their relevance, building on the fantastic 200 days at sea that Windsor had this past year, including two large NATO exercises and two NATO operational tasks, with follow-up employment by the other ships of the class over the next little while, and then looking at sustaining that capability through the remaining life and possible life extension of the boat.
As many of your colleagues have talked about, there are a number of requirements for us in the navy and the Canadian Forces as we go forward and adapt to the context. Taking full advantage of the useful life remaining in the boats is important so that we can buy the right resources at the right time as we go forward.
