The ambition of this truly international programme is principally to deliver a cutting-edge fighter aircraft, providing a credible deterrent to future threats. As my hon. Friend knows, this is a system of systems, and it is likely to include uncrewed aircraft, new sensors, weapons, advanced data systems and secure networks. Those wider capabilities may be developed together with our wider partners, or with our existing partners in that endeavour. We will continue to explore system opportunities between both our core partnership and more widely.
