Additional strength, probably not since the Kuznetzov will probably not even be in service by then. Nothing is known of the design, but may get some greater strength if Russia decided to go with a larger vessel in the order of 65-70,000 tons like the Queen Elizabeths. Even if it is built, it is curious what aircraft it may have aboard. The Su-33 Carrier Aircraft is no longer in production, Su-25 isn't either, Russia's have no dedicated AWACS aircraft for carrier use, so it leaves the MiG-35, which will be a 4+ gen aircraft when every other major player with carriers will be fielding 5 gen aircraft.
The real strength addition will be the 4 Mistrals if they are bought.
