The Leviathan is a helicopter that appears Grand Theft Auto: San Andreas. It is based on the UH-3 Sea King. It is the second largest helicopter on the game and has the ability to land on water thanks to its boat-shaped hull. It is very slow and sluggish, and strangely has the same rotor sound as the Hunter, Cargobob and Raindance. Its name comes from the biblical creature of the same name.
The Leviathan is used in the mission Up, Up and Away with a crane with a magnet attached to the bottom, that can lift vehicles. There is no way to obtain any helicopter with a magnet like this outside of this mission. The Leviathan from this mission can be saved but its magnet will not be saved in the garage. Once completing the mission a Leviathan will spawn at Verdant Meadows but it does not come with a magnet.
