Russian dry docks and maintenance capacity

Where are Russia's dry docks, and could they help Britain's docking shortage?

Facilities exist around the Black Sea, in the Kola region and in the Far East. Their condition is questioned, and British use is ruled out.

The initial focus on Black Sea facilities is qualified by acknowledging submarine docks in the Kola region and Far East. Political connections are suggested as helping the Black Sea fleet attract maintenance funding. The tentative estimate is that only two of about six submarine docks elsewhere are in good enough repair to function fully. Sending a British submarine to a Russian dock is rejected as a practical proposal.
