Based on the Victory Games (and now Compass Games) 'Fleet' series of modern naval warfare games, this game focuses on Pacific Northwest area of operations, specifically in the Alaskan waters, the Bering Strait, and the Sea of Okhotsk. The latter was an important underwater staging area for the Soviet (and now Russian) Navy's ballistic missile submarines. The US Navy and Japanese Maritime Self-Defense Force engage the Russian Naval Surface, Submarine and Air Forces over these disputed waters and bases, with their modern navies, guided by internal and external political forces.
