I thought I saw somewhere (JDW??) that MRA 4 for Uncle Sam is not going to happen.
The aircraft was possibly going to be offered as a P-3 replacement, but the Bungling Baron failed to get his act together. Sadly for t'Baron's coffers, the DoD informed him that, unlike the MoD, they wanted the submission in at the time specified, not as his convenience. T'Baron kicked up a small fuss, but DoD replied with a sentence allegedly including the words 'it' and 'poke'. At which point, t'Baron announced that he was not going to bid for the project after all, so there.
The potential US partner (I believe LMTAS) breathed a sigh of relief....
If we're lucky, BEagle might have found a transcript of the conversations about this and reproduce it here....
