Arguably, it's one of the two most major capabilities required for our north immediately. Given, if we have seen Chinese and Russian collocated drills just in the past six months here, our ability to provide an effective aerial defence in the north is a vital necessity. Given the age of the aircraft that we have currently, crew shortages due to this aging system and morale issues as well to some degree, I think it's absolutely vital that this capability needs to be replaced. I would say other areas, such as AEW or even having an effective patrol submarine would be effective, because that would allow us to have a greater deterrence in this area.
Just as a very quick point, I would say that we need to be faster at how we procure systems overall. That is the underlying issue across the entire system. It has taken basically 15 years to make a decision on the F-35 or on some of these other programs. It's really what's hamstringing the forces to actually deal with these issues. I'll leave it at that.
