The torpedo is a long, hydrodynamically shaped cylindrical object about 4-6 meters long, with a propulsion system at one end. It contains a sonar system and control surfaces for tracking and following a target, and a warhead for blowing said target out of the water (or writing graffiti on its lower hull, if you prefer). It is usually fired from a tube, which is flooded with seawater annd then opened at the front, after which the torpedo engages its propulsion system and zooms towards its target. Upon contact with the target, or coming within a preset range, or whatever other fuse or condition was set before the torpedo was launched, the warhead or other payload activates.
Note: Only workes underwater or on the surface of a body of water or another liquid. It can be dropped from an aircraft or launched ballistically, but if it doesn't land in water or some other liquid it will probably just sit there and spin its propeller (or use whatever other propulsion system it has to little effect), if it wasn't detonated or destroyed by the impact.
Warheads/payloads may include:
Explosives
Nuclear device
Antimatter
Aether warhead
Other destructive/exploding warhead
EMP warhead
Fish food
Sonic shockwave
Paint/Ink cloud
Graffiti artist droid
Nets
Electrification Package
Pirahnas!
Other stuff
