Even then the Black Sea fleet is basically outnumbered by the Turkish Navy and the Pacific Fleet by the Japanese Navy. Russia tries to counter this mismatch by relying on high speed cruise missiles like the Oniks and now the Zircon.
where do you get they relying on high speed missiles that are fired from ship or ground?. it will be very minor number and they simply not have the range unless put in bomber for air launched.
Russia relying on high altitude upgraded A-50U for time sensitive targets like fighter starting on tarmac. see my earlier link.
In 2015 Caspian flotilla could hit Syria with land attack missiles.. see that increase range of KH-BD. this further put shipyards at disadvantage as missiles and drones will come at lower altitude from sea. you may have also observed that Ukraine is not sending those large aircraft type drones towards Caucasus mountains.
At the current pace of construction it would likely take another two decades before the Russians finished their naval buildup.
The extra people that they hired for aviation, air defense, drone and satellite factories will not work for shipyards. smaller ships are dealing with drones and air defense. Most of missiles are air launched.
The interview revolves around how to hit smaller targets with missiles (not gun) efficiently. using Pantsir to hit surface ships at 10km. increasing the load out and missile speed. Putting it on ship weight only greater than 300 ton for Naval Pantsir. Shoigu took CIS ministers to essentially Pantsir factory. this is the trend to provide highly automated air defense to close the gaps. If Russia with such extensive experience with land air defense cannot close the gaps yet what others have any hope from real saturated attack.
