I am just wondering if it would have been possible for Russia to hold onto those 4 Kiev Class ships and later came up with a standard configuration to convert all of them to ski jump carriers like they did with the Vikramaditya
That would give Russia 4 pretty good ski jump carrier along with Mig-29K
I don't think the Russians were ever fully committed to carriers and felt they could never be the equal of the USN in operating them. To the Russians they are mainly just air-defense ships. They just don't have the will or methodology to properly operate a carrier.
I wish I could find a quote by a Russian admiral that I once read some years ago after observing flight operation on a USN carrier.
He stated that Russia could never achieve the coordination and team work necessary to operate a CV like the USN.
