The torpedo launch tube construction display lists the statistics of the torpedo launch tubes that you have both the resources and tech level to build at that time. When you build a beam weapon it remains in storage at the starbase until you fit the beam weapon onto a hull.
Torpedo launch tubes arm and aim standard torpedoes. A standard torpedo takes up 1 KT of cargo space. In combat the torpedo is moved from the cargo hold into the launch tube. The torpedo is the most powerful individual weapon on any starship and has a range second only to fighters. Major drawbacks of torpedoes are the firing time, the cargo space needed to hold the torpedoes, and the mass of the torpedo launchers and ammunition.
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.
For safety reasons a starship may only carry torpedoes that match the torpedo launch system it has. Freighters may not transport torpedoes.
Ships can convert their torpedoes into deep space mines using the Lay Mines mission.
