i know the
Admiral Kuznetsov's sister ship never had them installed, the
Liaoning.
Which makes her a better ship, since she has no business to getting into ship-to-ship combat range!
"Your a carrier! Getting focus carriering!" She training ship now until the bigger boats get online. Her near-sister ship is on verge of being commissioned, only known as the Type 001A.
As of August 2019, she still going on Sea Trials, her 5th one as of August. She didn't show up for the big PLAN sea view, so she must still have some issues to work out still.
