Torpedoes are the most powerful weapon carried on a starship and have a range greater than beam weapons. Many small ships can be destroyed by a single hit from a high tech torpedo.
All torpedoes take up one kiloton of cargo space. In combat the torpedo is moved from the cargo hold into the launch tube. The major drawbacks of torpedoes are the cargo spaces needed to hold the torpedoes and the mass of the torpedo launchers.
A launcher is only able to fire torpedoes designed for it. For example, a mark 5 photon torpedo can only be fired from a mark 5 photon torpedo launcher.
Planets that are left undefended by starships can be defeated by an enemy starship with high tech torpedoes.
Torpedoes are very good planet and starbase killers.
On average, 35% of all torpedoes fired at enemy ships miss.
Ships can convert their torpedoes into deep space mines.
