So how does this work then?
A number of USAF C-135B-04-BN, Boeing Model 717-166 were converted to RC-135M then RC-135W.
New build RC-135-01-BN, Boeing Model 739-445B subsequently became RC-135C, then RC-135V or U.
UK purchases KC-135A-27-BN, Boeing Model 717-148, subsequently converted to KC-135R, and now converted to RC-135W by L3.
For starters, how much does the difference in Boeing Model numbers contribute to lack of read-through evidence for UK certification? This is going to get interesting.....
