Thank you for that question.
Let me start by saying that in 2008, when the Canada First defence strategy came out, there was a very clear understanding between the director of air requirements and me that he and his team would be developing the requirements while I and my team would be doing the analysis against the requirements. We ran two very parallel paths. As those requirements were finalized through the early part of 2010 and as my team and I studied—in some areas, at very highly classified levels—the capabilities of the range of options, it was absolutely clear that, measured against the requirements, there was only one option, the joint strike fighter, the F-35, that met the mandatory requirements. In comparison with the other options, it is revolutionarily different in terms of capability.
