The Prometheus-class was one of the most advanced starships fielded by Starfleet in the late 24th century. It 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 Prometheus was equipped with advanced phaser arrays, quantum torpedoes, regenerative shields, and ablative armor, and its warp engines were designed to outrun even the fastest starship of the Federation fleet. One familiar feature (as seen on the U.S.S. Voyager) is the Prometheus also has the ability to land on a planet. The Prometheus was so highly classified that only four Starfleet officers were trained on how to operate the prototype ship before it came into service.

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. Combined with the extensive automation, the Prometheus could be run by as few as four people.
In addition to standard automation systems, the 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).
The prototype vessel USS Prometheus was launched in 2374.
In an alternate timeline, vessels of the Prometheus-class would be amongst the Federation fleet that engaged the forces of the Sphere Builders during the Battle of Procyon V in the 26th century. The battle also included the U.S.S. Enterprise NCC-1701-J and a Dauntless Class starship
