Is there any data on the maintenance of the J-20?
From what can be understood from the Finnish F-35 purchase contract is that the maintenance of the invisible "paint" of the aircraft is incredibly complex and expensive, I seem to remember that half of the contract was the refurbishment of Finnish airbases for the aircraft.
If you destroy these maintenance hangars you quickly degrade the F-35 of its greatest advantage, which is invisibility and in general what the whole aircraft depends on, which is a bit stupid if the war drags on and doesn't last just a few weeks ...
