If not because of the ongoing Global Combat Air Programme (GCAP), I think we must produce and field more of the new and latest fighter jets to keep the RAF and our Military Industrial Complex up to date. I believe increased uncertainty regarding the Trump administration's position should also see the UK distance themselves from the US and focus on the development of the GCAP program and further improvements to and construction of new fighter jets.
