You're, in effect, keeping the binder twine and the duct tape going for the F-18s for as long as you need to go in order to be able to get to your price point around 2018 or 2020 for, if you will, cheaper versions of the F-35.
The Israelis have taken a different route. They've essentially said they can't live with the uncertainty of the F-35 program and so they're upgrading their F-16s. Now, they live in a different environment, obviously, than do we. Is your plan B, effectively, like the Israelis, to upgrade your F-18s to keep them in the air longer?
