Help with aiming gun

i need to make a thing like this, http://www.flashkit.com/tutorials/G...Ju-81/index.php

but i dont want it that fancy though. i have a battlehsip that launches torpedoes. i want the gun of the battleship to aim (not perfectly but not way off so the gn can have 8 directions instead of every direction.
