Development on the Prometheus-class starship project began in the early 2360's at the Beta Antares shipyards. With the Dominion threat becoming more serious, development was stepped up and contruction began in the early 2370's. The Prometheus design borrows its shape from the Intrepid-class starships, except it features four standard warp nacelles similar in design to the nacelles used in the Sovereign-class starship. In 2374, the U.S.S. Prometheus NX-59650 was launched and began top secret field tests.
The Prometheus features four standard warp nacelles and one "mini-nacelle." When separated during MVA Mode, the larger "bottom" and "middle" sections each receive two nacelles. The command module containing the main bridge is also warp-capable. When the ship separates, a "mini-nacelle" on top of the command module is raised. The Prometheus utilizes a new, more efficient warp design that allows it to safely travel at warp speeds without damaging subspace. The Prometheus is the fastest starship in the Federation fleet, capable of sustaining a cruise velocity of warp factor 9.9. It also features the bio-circuitry and gel packs developed and refined in the Intrepid-class starships.| SPECIFICATIONS (MERGED) | U.S.S. PROMETHEUS NX-59650 | |
