CAATSA sanction on Turkey has nothing to do with S-400. Even if Turkey bought obsolete S-300 it will also be same sanction. It is US law which sanctions countries that buy from Russia because Russia is rival of US. The case of Greek S-300 is different in that Greece never bought S-300 from Russia but rather from Cyprus. Hence Greece is not subject to CAATSA the way Turkey is subject to CAATSA considering Turkey bought from Russia, not from Cyprus. Had Turkey bought S-400 from China instead of from Russia Turkey would not be subject to CAATSA and will be flying F-35 today.
The S-400 radars will be able to observe the F-35 “in all its flight profiles, thus being able to identify weak spots in stealth capability,” according to , a professor of electronic and radio systems at City, University London and a member of the board of the Association of Old Crows, an association for radar and electronic warfare professionals.
