USS Discovery (tanker)

The Tanker that appears in MGS2, named Discovery, is used to secretly transport the first Metal Gear RAY. It is at first guarded by the Marine Corps, being commanded by Scott Dolph, until eventually it is taken over by Sergei Gurlukovich's mercenary army, along with Revolver Ocelot. Solid Snake then infiltrates the Tanker, searching for photographic evidence of Metal Gear RAY. The tanker is eventually sunk by Liquid Snake who has taken over Ocelot's body.
