Curator asked about the Sea of Okhotsk Bastion - Concept and Reality (echoing similar for Barents Bastion and Northern Fleet)
Key finding: The Sea of Okhotsk bastion is Russia's primary mechanism for preserving its Pacific second-strike nuclear deterrent. It is a layered concept — not a single defensive line — encompassing coastal missile systems, island chain fortification, submarine patrol areas, and aviation coverage. Japan's expanding ASW capability and the AUKUS nuclear submarine programme are the two developments most likely to complicate it over the next decade.
