Could you direct me to the posts, if you remember? The CV-001 thread is rather dauntingly huge.
I recently discovered Weibo and just saw it on one of the big military Vs and I thought it was new.
Don't believe everything on Weibo or Chinese internet unless it's from a known reliable user with a good track record.
As for the old posts, I probably can't find it either because Im not even sure which thread it was in let alone which post it as (might have been 6 months to a year ago). But you can find other pictures of Liaoning with those modules on deck from its early trial days that show the modules did not have any laser turret and only antennae and telemetry equipment.
And I don't think anyone seriously thinks it makes sense for the low altitude guard laser system to be tested on Liaoning either.
