Why Russia's submarine force retained operational priority

How much of Russia's submarine force was likely operational in early 2022?

Russia retained a fairly substantial operational submarine force, supported by budget priority and continuing construction and upgrades.

The Russian submarine arm appeared more credible than capabilities that had suffered more obvious neglect. Submarines continued to receive funding priority. Regular construction and modernization added and upgraded boats over time. This is a broad readiness judgment rather than a hull-by-hull count.
