I am glad that my hon. Friend is not questioning me on inertia ratios and matrices. The capacity is there, but it requires planning ahead. That is why the industrial strategy mentions the need to invest in science and research and development—it is important that we do that—and the need to look forward to make sure that we have the skills in the workforce to fulfil the order books. The purpose of having a long-term industrial strategy is so that we are prepared to reap those very opportunities.
