An unarmed variant of the Primus class battlecruiser, this luxury liner was used to ferry VIPs beyond the borders of the Centauri Republic. In 2259, one such vessel transported Emperor Turhan to Babylon 5, under heavy escort. In 2262 a Primus Liner was scheduled to transport Ambassador Mollari from Babylon 5 to Centauri Prime, although the liner was forced to leave without their passenger. It would prove to be a lucky escape for Londo as a chemical explosive had been hooked into the liner's nav system and set to detonate as soon as it locked onto the Centauri Prime beacon.
