Actually I believe the Mars Passat PARs were never implemented on kuznetsov, due to various difficulties, cutting back on funding etc and what we see are just metal slabs. (Sidenote, gorshkov was the first vessel meant to be fitted with mars passat+fregat combo, but mars passat was a failure. So now the virkam is only equipped with fregat as well. If Mars Passat was a viable system I'm sure the indians would've requested it be retained aboard vikram. Interesting to note PLAN went with SAPARS+sea eagle combo on liaoning, which is basically a 21st century peer to the intended mars passat+fregat aboard gorshkov/kuznetsov)
And considering Varyag was an empty hull when she was towed to china and the ability of indigenous industry to produce weapons and electronics that can meet or exceed late cold war soviet technology, I would've been very surprised if PLAN decided to fit kashtan or gauntlet ciws
