Disruptor cannon

A disruptor cannon was a directed energy cannon weapon commonly used aboard starships of many different species.

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. These cannons were capable of firing in either disruptor pulse or beam modes. 

These weapons were also found in later designs of Klingon Birds-of-Prey, Negh'Var warships, and cruisers.
