Absolutely. We need to be able to build mass into our air force, as well as exquisite technology. One of the key changes we want is rapidly to reduce the amount of time it takes to develop the new airframe. With the F-35, we saw that go on for far too long, and we need to reduce that period. I would like to see Tempest flying in the first half of the next decade, and we should bring forward the technology and give this project the inspiration and the drive to make it a reality as quickly as possible.
