Why are domestic media and countries so secretive about H -6 (Figure-16)?

H -6 was once considered as a favorable weapon for the PLA to deal with aircraft carriers, and it was improved and upgraded to a great extent. But, personally, I think what you said is so confidential: it's just a mysterious bluff. H -6 belongs to the old model. After improvement and upgrade, it can be said that it has played a full role. No matter how difficult it is, it cannot become an advanced modern weapon. If our army has an urgent need for long-range strategic bombers, developing new models is the ultimate solution to the problem. As for Tu-16, the full name is Tu-160, which is the main long-range strategic bomber of Russian army and has nothing to do with China.
