It’s all in metric now.
The tanker will have GE Engines, and all the refueling and navaids will be installed in a plant to be built in Georiga,
USA. 4000 pers employed.
USAF wanted an AC Tanker with 2X capacity of KC-135 —
Boeing didn’t come up with the required AC as spec’d.
And it’s likely that the KC-45 won’t be using the CF6-80 variant now used, but likely a modified GENx engine. This will lower fuel burn, which improves the range over the current A330-200F.
