Sub Command, subtitled Akula Seawolf 688(I) is a submarine simulator computer game designed by Sonalysts Combat Simulations and published for Windows systems by Electronic Arts in 2001.

The player commands one submarine: a United States Navy Seawolf, a Russian Navy Akula, or a 688(I).

The single missions range from search and rescue, battle group escort, tailing enemy boomers, spy missions, and general-purpose search-and-destroy.

Many missions strictly prohibit firing on the enemy as they are expected to mirror real life Cold War objectives and get in—get out without being seen.

In multiplayer mode, this game allows up to eight players to play each other via LAN, IPX or IP connections.
