Neutron gun
The Neutron Gun was an energy projectile weapon used by the Terran Confederation and Kilrathi fleets. As of 2654, the neutron gun was the most destructive gun type. It traded heavy damage in exchange for a short range, a tendency to heat up quickly and a high power requirement.The short range of the neutron gun was known to fool inexperienced pilots into deadly close range dogfights, klling some. Neutron guns were found on the Rapier II, Raptor and Jalthi. They were featured in both Weapons of the Terran and Kilrathi Fleets and Borger's All The Sector's Weapons Systems. Variants include the Mk. 40F Neutron Gun.

Neutron guns do heavy damage, but only at close range. No other projectile weapon provides an equivalent level of destructive capability. The down side is that neutron guns heat up rapidly and eat up power at an alarming rate. Also, the neutron gun's lack of range has led many fool-hardy or underskilled pilots into close-quarter combat for which they were ill-prepared. Some of those pilots never made it home.
