The oily and brackish waters of the Russian Northern Fleet submarine base part for the passage of the colossal special purpose Omega II-class submarine Belgorod, on a mission to hold the United States hostage.

The Sea of Okhotsk north of the Japanese Home Islands is a cold and unforgiving place. Its icy, dark waters can change from a glass-smooth calm into a raging maelstrom in a heartbeat.
