From Wikipedia:

The goal is to sink the entire enemy fleet without sinking the player's fleet in the first place. 

In this updated version, both the player and the computer receive additional firepower from military aircraft and support weapons. 

There are even scenarios that run the player in the pregame game, which he must resume (and overcome the gloomy scenario). 

This video game was mentioned in the old Nintendo Power issue. 

There were also other versions of Battleship, including Battleships for Amiga, Atari ST, Commodore 64 and Spectrum, Battleship for CD-i, Battleship for Game Boy and Game Boy Color, and others for PC and mobile phones. 

There was a sequel to Super NES and Sega Genesis, Super Battleship.
