Editing Weapons in Star Trek (section)

===Plasma cannon===
Plasma cannons are a form of directed energy weaponry used by both Earth Starfleet and the early Romulan Star Empire. On Starfleet vessels, they are the precursors to phase cannons. Plasma cannons fire a plasma discharge in the form of a beam or a burst, similar to the plasma bullets fired by hand-held plasma weapons, but much bigger in size. The NX-class is initially armed with plasma cannons.
