"Every one of the more than 825 F-35 fighter jets delivered so far contain a component made with a Chinese alloy that’s prohibited by both US law and Pentagon regulations, according to the program office that oversees the aircraft.
The component -- a magnet used in an aircraft-powering device supplied by Honeywell International Inc. -- has been used in the plane since 2003, the Pentagon’s F-35 program office said."

"A new report from data analytics firm Govini measures Chinese penetration of the U.S. defense supply chain and concludes that our industrial base cannot deter China.
Released this morning, the report was issued by Arlington, VA-based Govini which was awarded a five-year $400 million contract from the Pentagon in 2019 to deliver data, analysis and insights into DoD spending, supply chain and acquisition using a database it continues to compile.
Its simplest and most telling insight lies in the authors’ observation that;
“U.S. domestic production capacity is a shriveled shadow of its former self. Crucial categories of industry for U.S. national defense are no longer built in any of the 50 states. With just 25 well-constructed attacks, using any of a variety of means, an adversarial military planner could cripple much of America’s manufacturing apparatus for producing advanced weapons.”"
