Long March 9's new 16-meter fairing is comically gigantic and you could theoretically put a Starship second stage inside it!
New blueprints of Long March 9βs factory reveal that it will have a 16-meter diameter fairing! To show how massive that truly is, I have compared it to past, current, and future launch vehicles that are also huge in size.
I honestly do not see a reason why a rocket would ever need a fairing this large π
