Shocking photos of stealth fighters F-35C Lightning II covered with the rust of the US Navy have appeared online.

Axar.az reports citing foreign media that the photos below clearly show three rust-covered fighters, as well as an F-35C Lightning II take-off fighter also covered in rust. According to INF, when asked, Pentagon spokesman Joe Dellavedova said the rust was caused by a manufacturing error by arms manufacturer Lockheed Martin, with all models being affected. It’ll be “fixed” in new batches of F35s.

This is not the first time that a problem with the metal or metal alloys of modern stealth fighters has been reported. One of the first public reports of problems with the F-35 arrived in early 2019 from the Australian Air Force, which reported a problem with intergranular corrosion. Australia then hired the auditing and consulting firm KPMG to assess the problem that arose when using fighters in low humidity areas. But back in 2017, Australia was the first country to report various cracks in the body of the machine.
