Stupid?
Ok, I didn't mean that.
My concern over this procurement is that in the R1 era the a/c and its systems had capabilities that differentiated it from the RJ and hence the U.S. Valued the UK input as it filled a niche coalition requirement, as well as a unique UK need. Now, unless the UK RJ is fitted with different kit to the U.S. Ones, the RAF can just replicate what the U.S. Can already deliver.
