Disruptor
A disruptor cannon is a directed energy weapon commonly used aboard starships of many different species. Disruptor weapons generally carry more energy then standard phaser weapons but lack in accuracy and fast discharge. (Star Trek: Deep Space Nine Technical Manual) Klingon 22nd century Klingon Birds-of-Prey were equipped with an impressive arsenal, for the time, and included wing-mounted (and belly mounted) disruptor cannons and photon torpedo launchers. (ENT: "Borderland") These cannon were capable of firing in either disruptor pulse or beam modes. (ENT: "The Augments") These weapons were also found on Romulan Valdore-type Warbirds, Ferengi D'kora-class attack cruisers, Cardassian Hideki-class assault vessels, and Klingon Birds-of-Prey, Negh'Var and Vor'cha-class cruisers.
