Here is the Rescaled version of the X - 303 Prometheus. Its weapons are relatively weapon, although its numbers make up for this. The missiles are slow just like the show and do less damage than a photon torpedo, however the Naquada enhanced missiles will cause more damage against the hull of a ship but seem to have less effect on shields. Against most ships of the startrek TNG era this may struggle against most ships, although it will give most of these ships a good fight with its missle spamming ability. The Prometheus has been Rescaled to a size of approximately 150 - 200 metres and is about half the size of the Intrepid Class (which is 300 - 400 metres). This ship can easily destroy the death gliders currently avaliable with its Railguns.
