The neutron gun was specifically created as a weapon for medium and heavy fighters when the war first began. It releases energized blasts of charged neutrons, drawing more power then the mass driver or the laser. For the majority of the past two decades, no other energy blaster was able to provide an equivalent level of destructive capability. The down side is that neutron guns heat up rapidly and eat up power at an alarming rate. The neutron gun's lack of range has led many foolhardy and underskilled pilots into close-quarter combat for which they were ill-prepared; some never made it home.

Recently Terran scientists have been able to come up with new energy weapons with more hitting power, longer range and less power drain, in effect making neutron guns all but obsolete. As of right now, Confed is in the process of now retiring all neutron guns in service and replacing them with particle cannons.
