No doubt, but that is tangential to what the S-400 is claimed to do, and if you don't mind me being blunt: neither us, nor any Russian forum goers, know if the S-400 is actually reasonably effective against LO aircraft. Maybe not even the Russians and American militaries do. Where the original claim comes from -- that Russia and China cannot shoot down an F-35 -- is beyond me. It is as daft as claiming that S-400 makes stealth useless. I take issue with such confident grand claims.
