Worked for the DoD in support of the Navy warfighter for 31 years and we were always vigilant as to part/material sources.....and that’s not just China BTW.
From scanning the article I got the distinct impression they are already considering waving the Chinese parts or materials restriction in this particular case.
“In late August, Honeywell was notified by one of their third-tier suppliers for the turbomachine that they were using alloy sourced from China which was then magnetized in the United States, according to a statement from Lockheed.”
Figures. A rare earth element is involved no doubt.
