Threat Vector

Submarine commander Alexi Novskoyy has been sprung from prison by a multibillion-dollar organization with a very special mission in mind. The company has designed a new submarine--the Vepr--which they will use to wreak havoc on international trade. To test its new weapon, Alexi must sink a cruise ship carrying the entire brass of the U.S. Navy--effectively decapitating the American fleet.

The legendary USS Devilfish is called in to stop the catastrophe, only to be ambushed by the ultra-advanced Vepr. With the Devilfish down, the Navy sends Captain "Kelly" McKee and the newest sub in the U.S. arsenal to hunt down and destroy the super sub. What they don't realize is that Alexi has his own plans, which have him heading straight for the shores of America.
