Type-XVII Phaser

The Type-XXII Phaser or Gravimetric phaser was a specialized particle weapon created by Starfleet Tactical and Science in the 2470s. It utilized by concentrating a coherent and compressed beam of gravimetric energy and gravitons towards a impact zone on an enemy vessel and inflicting a strong, artificial gravimetric shear.

In 2475 in the Battle of Bajor, the NX-7605 Exelixi class starship caused critical structural damage to multiple galactonian battlecruisers, showing the full potential of these phasers.
