The USS Ulyssess, NX-93103-D, is a Nimbus-class vessel under the command of Addiena J'rish Ashworth, assigned to the Alpha Centauri Institute.

The primary mission of the Ulyssess is as an atmospheric analysis vessel. The ship is equipped with 4 primary sick bays and 1 secondary sick bay. The secondary sickbay is significantly smaller than the others due to space requirements of the vessel's extra phaser array capacitors.
