Through the chairman to you, sir, if we look at the expected delivery date of 2016, I understand that some of Canada's F-35s will be part of what's called a low-rate initial production, phase 4, while others won't.
Could you describe to the committee the difference between an LRIP, the low-rate initial production, airplane and those that will be produced during the full production phase? Does this mean that the earlier models will need future modifications and will they be at the same operational level as the others?
