(Bloomberg) — The Pentagon has halted deliveries of Lockheed Martin Corp.’s F-35 after finding an alloy used in magnets for pumps on the fighter jet were made in China.
The F-35 program office “temporarily paused the acceptance of new F-35 aircraft to ensure the F-35 program’s compliance” with defense regulations “pertaining to specialty metals,” Defense Department spokesman Russell Goemaere said in an email.
He said the pause won’t interfere with operations of F-35s already delivered to the US military and partners abroad because “the magnet does not transmit information or harm the integrity of the aircraft and there are no performance, quality, safety or security risks associated with this issue.
“Once the issue was discovered,” the F-35 program office “found an alternative source for the alloy that will be used in future turbomachines,” Goemaere says.
Lockheed said in a statement that “we are working with our partners and DoD to ensure contractual compliance within the supply chain.” The contractor said the F-35 remains safe for flight, “and we are working with the DoD to resolve the issue as quickly as possible to resume deliveries.”
The turbomachine integrates the aircraft’s auxiliary power unit and an air cycle machine into a single piece of equipment that provides electrical power for ground maintenance, starting of the main engine and emergency power.
