Torpedo launcher (also known as a torpedo bank) is a common term for systems that deploy projectiles such as torpedoes and probes. Polities known to have used such devices include the Cardassian Union, the Dominion, the Klingon Empire, the Romulan Star Empire, and the United Federation of Planets. A torpedo tube is a part of a torpedo launcher. Torpedo launchers can usually be accessed by personnel from a torpedo bay. On several starships torpedo launchers also double as directed energy weapon emitters.
The pre-Federation Starfleet already employed spatial torpedoes and equipped the NX-class with launchers. After the introduction of photonic torpedoes, the existing launchers needed to be extensively reconfigured and integrated to the ships powergrid.
Starships and installations of the Starfleet made use of photon torpedoes and their launchers by at least 2267. By the mid-24th century, some Starfleet launchers were able to fire up to at least 5 projectiles in a single salvo and launch torpedoes in rapid fire.
