GATO

GATO is a real-time 3D submarine simulation game, where the player is a commander of a United States submarine in the Pacific Ocean during World War II against Japanese warships. Gameplay consists of missions where the primary directive is to navigate the submarine to track and intercept (multiple) enemy warships (patrol boats, destroyers, etc.) on the randomly created map (which consists of randomly placed islands) and close in for the kill with torpedoes.
