The Type 9 disruptor cannon is one of the most advanced types of disruptor cannon currently in service with the Klingon Defence Force. Currently the mainstay of Klingon combat vessels, it packs a major punch comparable with that of a Federation Type X phaser or a Cardassian System 5 phase disruptor. The disruptor is unusual in that it trades firepower for rate of fire, meaning that it fires relatively slowly compared with other Klingon weapons. To counter this deficiency, it is often allied with the Type 8 disruptor.
