they may came to conclusion that aircraft carrier is not effective where they are going to see combat
There is an easier option which is that the Russian Navy wasn’t ready for an Aircraft carrier and still isn’t.
Remember the Liaoning, she wasn’t bought from Russia she was bought from Ukraine. The Soviet navy was dependent on the Mykolaiv north and South for much of its larger tonnage ships. All the Russian Carriers were built in the Ukrainian yards.
When the Soviet Union collapsed the Liaoning and Kuznetsov were both in docks in Mykolaiv neither was complete the Liaoning was the less complete of the two.
Because of that when Ukraine declared independence she should have ended up in the Ukrainian Navy, However On the day of the Ukrainian independence vote. Half the crew of the Kuznetsov mutinied and stole the ship setting sail to the Northern fleets.
On arrival she ran into problems as none of the other fleet yards of the Soviet Union now Russian Navy were set up to support an Aircraft carrier. Despite only actual at sea service being less than a cumulative year and a half the Kuznetsov has had to burn her boilers and systems like she was in constant service. This is due to the fact that infrastructure was lacking or never planned by combination of short sight or corruption.
You might recall in 2018 the only dry dock the Russian Navy had large enough to support the Kuznetsov sank well the Carrier was inside of it. That event happened after said dry dock lost power. The Dock had back up generators that could have prevented this accident but the head of the Yard pocketed the money for the diesel fuel.
The Carrier has had to be towed by tug on a number of occasions due to breakdown.
The USN was on at least one occasion prepared to render humanitarian assistance when it ran out of drinking water.
At least this time they had enough aircraft for the deck. One of the previous Soviet carriers had more pilots than aircraft so to keep them dastardly westerners scared when near NATO Intelligence aircraft, aircraft being cycled would be shuffled below decks repainted a new number and then moved back up. Russian Carrier program is basically a black comedy, made all the blacker by fact it’s reality.
