There's a priority for US-based, but it's not a hard requirement. KC-46 was almost the KC-45, that was an NG/Airbus effort built on the A330.

Which has been a complete shitshow while the Airbus alternative keeps snagging up customers around the world.

> By January 2021, Boeing's losses on the program were estimated at $5 billion (~$5.55 billion in 2023).[88] At the time, it was expected that the KC-46 would not be combat ready until at least late 2023.[89]

Yep, why I wrote this in my other comment: KC-46 the cursed refueler program.

It's an excellent example of the self-inflicted wounds plaguing US DOD acquisition and sustainment programs.
