The Blue Marine is a small submarine built by the Star Fox Team. It is only used in Star Fox 64 when Fox dives into the Aquas Ocean to destroy Andross's bioweapon. Its main weapons are an unlimited amount homing torpedoes and two underwater lasers. Even though it is a submarine, it can still brake, use a boost, and do barrel rolls. It is ejected into the water by making the Great Fox be like a boat and have its lower front hanger in the water. The Blue Marine then drives out of the hanger.
