From the press i've read nobody really knows exactly where they come from although it's unlikely to come from AirTanker. They're more likely to be second hand A330 to be converted to MRTT standard.Brasil wrote:Brazil recently announced the acquisition of 2 A330. I believe they will come from the AirTanker fleet. One of them has already come to a demonstration in 2019.
It's not even a given they will be converted into MRTT, most of the public domain discussion focusses entirely on the strategic transport role
