The Kuz was designed for all out war, with all forces fight against similar sized enemy forces.
The Kuz designed or this purpose, but due to that it is not so fit to fight against weaker enemy.
The other is the US model, where the ship is designed / optimised to fight against enemy that is weaker than the attacker, and the carrier works in a protected environment.
Practically the US model is based on superior industrial / manufacturing base , that can make average/above average quality equipment for cheap in huge volume.
Actually that is the reason why it is so important to know the manufacturing cost in relationship to the country economic capability.
