If 2016 is still just a planning concept and we add in the delays, most of the acquisition is intended to follow that by about three years. If we have a delay of three to five years, we'd be well into the 2020s for the purchase of what I think you referred to as the block III purchase. They are presumably, or at least theoretically, the lower-cost airplanes. That is well beyond the lifetime of the CF-18 that you've described today.
In terms of readiness, these planning concepts are great, but when we're talking about having planes in the air and national defence, the timing seems well out of whack by five years at least. What are you doing to account for those very real possibilities?
