Local time on the evening of September 12, east of the Oakland Islands, "Wujiang" class submarine.
Like the "Han River" submarine that had fired the first shot of the Boss Bay War by launching a cruise missile in Boss Bay a month ago, "Wujiang" belonged to the "Nanjiang" class, as the seventh vessel of its class. The only difference was that "Wujiang" was not equipped with a Vertical Launch System for firing cruise missiles.
For submarines operating in the Sunset Ocean, the presence of a Vertical Launch System was not of significant consequence.
Inside the command center, more than a dozen officers and soldiers were intently watching Major Ran Wenqiang, the commander, whose gaze, however, was fixed on the vertically standing information screen.
Just over ten minutes earlier, Ran Wenqiang had ordered the retraction of the towed sonar array and to ready for battle.
