But the USSR had.
The USSR was a bigger country with a bigger population and an entire western world to confront and it largely collapsed because it was spending too much money and effort on ultimately useless technology... they made 40,000 odd tanks... most of which ended up being scrapped and were to a total waste of money and effort.
He built large destroyers and even aircraft carriers at the end of its existence.
It was laying down larger and larger ships, but was never the global naval power that even France used to be or Britain... let alone the US.
If you could magically make appear a US level of naval force and gave it to Russia right now the Russian economy would be seriously damaged just trying to keep it in service and operating at maybe a 20% readiness level... which would make it effectively useless, and also a serious financial burden on the Russian society... much like it is today for the US who probably couldn't mobilise more than 3 or four of its 10 carrier groups right now even if WWIII was kicking off because despite spending an eye watering amount of money building the forces, they have not kept up with maintaining and supporting those forces... look at their problems with their newest carrier that is not really a carrier because it can't operate fixed wing aircraft from its decks... its newest destroyers are a joke... a very expensive joke by the way, and their new LCA ships or whatever they are called are a total disaster too... the US Navy is in a terrible state and it only seems to be getting worse as F-35s get introduced and are being found out as the serious mistakes they are...
Russia has destroyers and cruisers and a carrier, but they are old and in need of upgrades... their new corvettes and Frigates are state of the art and superior to their cold war destroyers, and when they are ready to start producing replacements for their destroyers and cruisers they are going to be formidable vessels.
Their budget is a fraction of teh budget of the US, so they can't just whack them out by the dozen over the next few years, but that is OK... taking the better part of the next two decades to build them gives them time to expand their shore infrastructure to support these new vessels that are on their way.
There is no rush.

It was, because it needed to confront both NATO and the US Navy in a global game of chess. Russia needs no such capacity.... and to attempt to create such a force would be self defeating... exactly what the Americans and the British want them to do... fool them in to an arms race that wastes money and resources and leads to neglect of the real needs of the Russian people... just like the western countries have funded their military at the expense of the infrastructure and well being of their citizens too.
The same shipbuilding industry.
No it isn't. The Soviet ship building industry included the Ukrainian and Crimean and Baltic shipyards, which are no longer connected, though the Crimean shipyards were returned in 2014 they are getting up to speed, the others are lost along with the demands of a super power to match the western navies around the world.
Anyway, looking at your english lvl shows that you are probably from China and you are here only to troll.
He is probably a bit giddy because China never had much of a naval tradition and their current changes probably make him think China will be ruling the worlds seas by 2030, but he clearly does not understand how such things work.
Having lots of ships means nothing if you are not sophisticated and clever in the use of such assets.
Look at all those shiny powerful air defence systems the Saudis had and how easily their defences were penetrated by subsonic cruise missiles and simple drones...
