Per the latest paid episode of 察话会, Fujian's electromagnetic catapult launches have already happened! This includes "the first electromagnetically launched fifth gen" (not that this title is particularly important)
The going theory is that they decided to withhold the footage for some reason, and will likely release them when the ship is officially commissioned.
Moreover, they also talked extensively about the new electromagnetic arresting gear, which is said to be much better for the pilots (and of course importantly, for the airframes)
I'm not done listening to the episode yet, but so far it's been a pretty good one and recommended.
Elsewhere, Yankee made an offhand joke on "just build a Type 077"..... Yankee you sneaky....
Also Shilao called 北六 the J-50 lol (though he wasn't serious). Pass it down, it's official! Jk. But I find it amusing how this has circulated to them.
