Putin isn't personally hand stamping ship orders... But sure, the failure of the Russian MIC and its military leadership to provide a solution to Ukraine's Black Sea drone fleet is notable, but that's not to say that they won't eventually create one.
Though I'm not quite clear about why you're so critical of Russia's naval strategy. The Russian Navy is largely trapped. It's main priority is to protect a critical part of its nuclear triad, with all other roles being a functional luxury. It is making notable progress in regards to larger surface combatants and helicopter carriers (which are probably what it actually needs rather than actual carriers), but it is also limited by its own industry.
Development of new and larger radars, better sonars, better armaments are necessary to produce a larger warship. This happens regularly in China, but Russia is a much smaller country than China with a much smaller economy and it's still producing a respectable number of warship designs (and actual warships) relative to its size.
Quite frankly, it's significantly outperforming in MIC relative to its economy. Most nation-states simply cannot support an MIC this large and advanced. Compare it to the UK, which does need blue water assets to contribute to its fight and does have a large economy, large population, and market access to anything it could need. It's fleet isn't that much more impressive than the Russian fleet, and its other branches are woeful by comparison. The state of their MIC is also pitiful.
I suppose a better example would be RoK, who does have a very well managed fleet, other armed branches, and respectable MIC, but it's also much more modest in size with significantly less coastline and land to defend.
I don't think you can really say this is gross mis-management. Taking all the various factors into account, the current status and near-future prospects of the Russian Navy are fairly logical and respectable.
