The two systems “are very different,” the military’s F-35 spokesman, Joe DellaVedova, said in an e-mail. “The program has leveraged the lessons learned from F-22 development to enhance the F-35 across all subsystems, including oxygen system,” he said. “The F-35 program was immediately made aware of last week’s F-22 incidents,” he said.

“At this time, the program office does not see any commonality in the potential causal factors the F-22 program is investigating,” he said.

Lockheed Martin spokeswoman Laurie Quincy said in an e-mail that the F-22 and F-35 oxygen systems have “unique differences” but “as a precaution the F-35 team is reviewing” the Raptor system “design and performance to gain additional insight to improve the F-35 system if required.”
