The Planetary Assault Carrier of the Sh'ner-class served as a crucial warship type within the naval forces of the Ssi-ruuvi Imperium, deploying its D'kee-class planetary landers in both planetary invasions and engagements in space.

The 750-meter hull, protected by minimal armor, possessed a limited armament of only six ion cannons and a pair of tractor beam projectors, necessitating the use of escort vessels for protection. The vessel had six main launch bays in addition to twelve secondary bays for landing. Each of the main launch bays had space for a pair of D'kee landing ships. The dozen secondary landing bays were used for the purpose of receiving captured enemy spacecraft.
Furthermore, the carrier incorporated a dozen entechment labs designed to extract life energies from prisoners, alongside enormous energy storage units to contain the harvested energies. The ship's complement included a command crew of 60 Ssi-ruuk, accompanied by a workforce of 500 P'w'eck slaves and 300 robotic units.
To maintain control over the numerous P'w'ecks, their Ssi-Ruuvi overlords installed stun traps throughout the ship's corridors and chambers to enforce compliance. These traps were capable of inflicting severe agony upon the P'w'ecks, and could prove fatal to a Human.
