I guess it depends on which solution is chosen.
Let's be blunt here, Mr. Chair. The most specific information we have is on the P-8 because it is an existing product. All the other products and the information we learn through the RFI run by PSPC are developmental in nature. There is a lot of good work done to estimate when the products might be ready and how long they might last.
When we heard back from the RFI—and Simon, feel free to correct me if I have this wrong—most of the developmental options—“developmental” meaning they don't have an option today that meets the requirements—are looking at somewhere between 2036 and 2038 as the most optimistic estimate of when they would have a plane ready with all the systems. Then you have a lifespan beyond that.
If you look at the CP-140, which came into service in 1980, we're 43 or 44 years from there. That's a good guess. What we know about the P-8 is that the U.S. intends to keep it in service until the mid-2060s. Again, we have about a 40-year runway on that particular asset. It is the one we have the most certainty on, because it is an existing product.
