The Baltic naval problem in Operation Unthinkable

What could Allied navies do in the Baltic during Operation Unthinkable?

Use submarines and light forces cautiously while directing strategic power against Soviet logistics; sending heavy ships into the Baltic would expose them for little gain.

The Baltic is treated as a constrained Soviet lake filled with torpedo, mine, and air threats, making the commitment of capital ships an unnecessary gamble. Submarines and light forces offer more credible naval options. Strategically, the Allies would need to break Soviet logistics, especially rail nodes and gauge-transfer yards, rather than expect sea power alone to reverse the enormous continental balance.
