Dont be silly, why would UK need to rely on the US. In what area is US ahead of UK in jet tech. F35 is a US/UK joint venture.Just import F22..
the yanks trust you
F22 is also no longer being produced.....
I am glad UK has progressed with the tempest it will hand down beat everyone else. Its the right time to progress on from the EFT on to the next generation.
