When it originally announced that Canada was moving to CF-35s, the estimate was that the project would cost $19 billion. In my view, what is in the control of the department is that this information was based on outdated information. There were already up-to-date cost estimates for what a fighter jet would cost. They hadn't been factored in.
They also didn't include in that project all of the elements needed to make sure that the planes could reach their full operational capability, meaning that they could be used as intended. Some of the things that were missing were power grid upgrades in some of the infrastructure that was essential, and also some of the advanced weaponry. You needed to have missiles on those fighter jets if you wanted to use them as intended, and they weren't there.
This is why we say the cost estimates now are at $27.7. billion. There are at least another $5.5 billion that should be added to that in order to look at the cost of fully transitioning from CF-18s to CF-35s.
