Biggus,
Before I too retire to hopefully let this thread return to its original subject, once again let me stress I am not doubting the utility of the MRA4 if it works!!!! However, I assume that you are not equating the capability of the MRA4 with the B-52 and B-1!!!!
Both of these platforms have considerably more payload than the MRA4 will have, and have the advantage of better altitude options (B-52) or dash speed (B-1) than will be available to the MRA4. Even with the MRA4s gucci DASS, it will not be able to be employed 'over the wire' as freely as the B-52 or B-1 fleets.
Regards,
M2
