A Hellhound is a Kel-Morian fighter craft. It has air-to-air combat and air-to-ground capabilities and it can make the transition between space and planetary environments. It featured prominently during the Guild Wars and is the counterpart to the Confederate Avenger.
Hellhounds were equipped with nose cannons that fired lasers and rockets mounted on wing racks. Both of these weapons could be fired at ground targets. However, Hellhounds could be damaged by return small arms fire, though such fire was unlikely to ever actually down a Hellhound.
Upon training graduation, newly qualified Hellhound pilots had two steel "H" implanted into their right palm; those who shared a handshake are able to feel the "HH" groove.
