Did you see that on an official site or one of your junk news sites?Some legacy design decisions and compromises would have carried over to the detriment of the aircraft. If they had three different airframes from the start the aircraft would have been fastly superior.
There are currently serious concerns about the lifetime of the F35B airframe due to the weight saving exercises done.
A quick search appears to find a different story.
https://www.baesystems.com/en/article/f-35a-lightning-ii-airframe-completes-third-life-testing-in-unique-facilityA full scale durability test airframe of the F-35A aircraft has successfully completed its third life testing, equivalent to 24,000 hours of 'flying', in our unique testing facility at BAE Systems’ site in Brough, East Yorkshire.
Kathy Nesmith, F-35 Joint Program Office Airframe Team Lead, said: “The F-35 programme requires a service life of 8,000 flight hours. This is verified through durability testing to two lifetimes or 16,000 hours. Completing third life testing on the F-35A durability article will provide us the data to enable the warfighter to maintain and sustain this aircraft beyond 2050.”
Both the F-35B and F-35C durability test articles have completed 16,000 hour second life testing and are continuing with additional testing to maximize the life of the aircraft.
https://www.globalsecurity.org/military/systems/aircraft/f-18-service-life.htmEngineering analysis and testing of the F/A-18 program have resulted in revised service life estimates, from 6,000 flight hours to 8,000 flight hours for the A/C models, and another change is possible to 8,000 or 10,000 flight hours for the E/F models. These changes are based on the amount of fatigue life that is remaining on the aircraft at the time of inspection. Initial flight hour projections were made based on the engineering assessment (expressed in terms of hours) of when the aircraft would reach a fatigue life expended of 100%. Initial analysis resulted in an estimate of 6,000 flight hours.
That F/A18 seems like a pile of junk in comparison, doesn't it
