Standing at the helm of a Los Angeles Class 688I nuclear-powered attack submarine, you survey the best the Navy has to offer. Outfitted with the most sensitive sensors, navigation, and state-of-the-art communication equipment that money can buy, the 688I is yours alone to command. Using strategy and stealth, you'll monitor the movements of hostile targets, destroy enemy ships and subs, hunt for mines, and attack enemy convoys. Your primary goal is to complete the mission objectives while maintaining the safety of your crew and the diplomatic position of the United States. Should you fail, your final rest will be upon the ocean floor.
