The industrial plan for the F-35 was dictated by the nine nations, including Canada, to not be an offset program. In our terms, offset and IRBs are the same. It was required to be a best-value program, but it was also required that industries in all the partner countries be allowed to compete to build the U.S. airplanes. That was a fundamental requirement and that was the trade.
Our estimates today project the value of the industrial plan for Lockheed Martin's portion of the airplane to be about $9.5 billion U.S. The engine contractors and sustainment are not included in that. I know—I just talked to the Pratt & Whitney guys within the last day or so—that their value takes this to well over $10 billion and close to $10.5 billion.
There's quite a bit more coming with sustainment, but we haven't defined the sustainment plan yet. Canada's requirements have not been made known to us yet. As airplanes come into service here, the infrastructure to maintain, support, and overhaul them will also come with that.
