|This article is about the Vespid weapon; for the Imperial weapon, see Neutron Laser Projector.|
The heart of the weapon is a unique crystal found on the Vespid homeworld. The crystal is energetic and unstable, but can be modulated by the vibrations of the Vespid's wings. The crystal is mounted in a case designed by the Tau that projects neutrons through the crystal. The combination is one of the most lethal weapons of its size.[Needs Citation] Its neutron blast is so powerful that can easily punch through the most armour.
The weapon also has the added safety feature of only being able to be fired by a Vespid (other creatures cannot modulate the crystal).[Needs Citation]
