The Prometheus-class was a highly classified Federation starship designed for deep-space tactical assignments. It was one of the most advanced Starfleet vessels in operation during the latter half of the 24th century.


This class' prototype, the USS Prometheus, was launched from the Beta Antares Ship Yards in the Antares sector on stardate 50749.5. At the time of its launch, the Prometheus was so highly classified that only four people in all of Starfleet were trained to operate the prototype. (VOY: "Message in a Bottle")

In an alternate timeline, vessels of the Prometheus class were among the Federation fleet that engaged the forces of the Sphere Builders during the Battle of Procyon V in the 26th century. (ENT: "Azati Prime")

Technical data

Propulsion system

Capable of attaining speeds exceeding warp 9.9, the warp drive on board the Prometheus-class was designed to go faster than any other class in the fleet.

Defensive systems

The Prometheus-class was designed with an unprecedented level of automation, and, combined with its advanced tactical systems, was one of the most powerful combat ships in the Alpha Quadrant. The primary battle systems on board the Prometheus included regenerative shielding, ablative hull armor, as well as phasers, and photon torpedoes.

A unique feature included in the Prometheus design was the multi-vector assault mode, which allowed the ship to split into three semi-independent sections that could each deliver massive force against an enemy target. All three sections were warp-capable. In this mode, the Prometheus could easily disable a Template:ShipClass at warp, or a Template:ShipClass on the field of battle. (VOY: "Message in a Bottle")

Additional systems

In addition to standard automation systems, the Prometheus-class design also featured holoemitters on every deck, which allowed the ship's Emergency Medical Hologram (Mark II) to access all areas of the ship (most EMHs were confined to sickbay only).

Primary controls for the ventilation system were located in Jefferies tube 17, which was located five decks up from sickbay. (VOY: "Message in a Bottle")

Interior design

Main Bridge

The fact that the Prometheus class was mainly designed for combat was reflected in the design of its bridge. The bridge was obviously designed with efficiency in mind, providing the commanding officer with visual access to all major stations when seated in the command chair. Directly in front of the captain's chair, sunken down with three steps, was the location of the operations officer and conn stations, combined in one large console. Both officers shared an unobstructed view of the main viewscreen with the commanding officer. All other stations were mounted against the wall, running around the entire length of the room. Directly aft of the captain's chair was the master systems display, with Engineering and Tactical stations to the left and right, respectively, and to the captain's left and right, beyond these stations, were doors that both provided access to the turbolift system.

Ships commissioned





The Prometheus class was designed by Star Trek: Voyager senior illustrator Rick Sternbach and rendered as a CGI model by Foundation Imaging. The Prometheus-class interiors were designed by Voyager production designer Richard James, using re-dressed portions of the re-created USS Excelsior bridge that James had made for "Flashback", as well as the USS Voyager sickbay in addition to new sets.

In the DS9 relaunch series of novels Avatar, Book 1 and Book 2, a Prometheus-class starship named USS Cerberus served as Admiral William Ross's personal flagship, replacing the USS Bellerophon.
