The Pentagon has published a report, in which it was acknowledged that 50% of fifth-generation F-35 fighters were not suitable for combat action
Specialists have not been able to resolve a lot of technical deficiencies, which the renowned aircraft had been repeatedly criticised for
The efforts made have failed to improve the reliability of the fighters since 2014, despite the growth of their number
Improved versions of software for the fighter have had 31 updates, but key shortcomings have not yet been corrected.
Thus, as many as 1,000 flaws make the F-35 fighter aircraft just common aircraft
For example, F-35B modifications for the Marine Corps and F-35C for aircraft carriers cannot be refuelled in the air.
