Phase Cannons
A phase cannon is a phase-modulated energy weapon, a type of particle weapon that serves as a
successor to plasma cannons. The phase cannon is rated for a maximum power output of 500 gigjoules.
The cannons of NX class starships were mounted on retractable turrets that extended from the
ship's hull when deployed and rotated as they were being targeted. Phase cannons emit a
concentrated beam of energy that can be set at different yields.

Disruptors
A disruptor cannon is a directed energy weapon commonly used aboard starships of many different
species. Disruptor weapons generally carry more energy then standard phase weapons but lack in
accuracy and fast discharge. The Disruptor uses slow nadions rather than rapid nadions in generating
the energy beam. This gives the disruptor considerably lower energy conversion efficiency than phase
weaponry. This is partially offset by a moderate reduction in the size of the hardware required for the
weapon itself - the space freed up by this allows a higher power weapon to be installed in the same
space.
