GAO: Late F-35 parts ballooned from <2,000 (2017) to 10,000+ (2019), and Turkey’s exit could worsen schedule risk
A GAO review found F-35 parts delivered late rose sharply—from fewer than 2,000 in August 2017 to more than 10,000 by July 2019—pointing to persistent supplier delivery performance problems. The report warns that Turkey’s departure could further strain the industrial and schedule baseline.
