5.0 Propulsion Systems

5.1 Reaction Control System

The Prometheus is equipped with Starfleet's standard issue Reaction Control System, the heart of which are the RCS thrusters (short for Reaction Control System thrusters). The RCS thrusters are the standard maneuvering thrusters found on Federation starships and shuttlecraft. The thrusters utilize interstellar deuterium collected by the Bussard collectors to generate thrust. Like impulse, acceleration provided by the thrusters does result in time dilation effects so as a result high speeds, if the thrusters were capable of producing them, would not be advised. In order to conduct a full, emergency thruster shutdown, deuterium must be vented from the system.

Type: Standard Version 3 magneto-hydrodynamic gas-fusion thrusters.
Output: Each thruster quad can produce 3.9 million Newtons of exhaust.

5.2 Impulse Drive

The Impulse Drive on the Prometheus is, like all Impulse Drives, essentially an magnetoplasmadynamic thruster, consisting of a fusion reactor, an accelerator-generator, a space-time driver coil assembly and a vectored thrust nozzle to direct the plasma exhaust. The fusion reaction generates a highly energized plasma. This plasma, ("electro-plasma") can be employed for propulsion, or can be diverted to the power transfer grid, via EPS conduits, so as to supply other systems. The accelerated plasma is passed through the driver coils, thereby generating a subspace field which improves the propulsive effect.

Type: Outfitted with twin fusion-powered Krayne-21 impulse drives mounted on the aft section of the nacelle pylons. Built by Krayne Industries, the K-21 drives were specially designed for the Prometheus class with tolerances built-in for the ship specific geometry, as well as variable ethereal vanes for direction of hydrogen flow.
Output: The impulse engine can propel an Intrepid class starship at speeds just under .25c, at “Full Impulse” and an upper ceiling of .80c at three quarters the speed of light. Generally, Starfleet Vessels are restricted to .25c speeds to avoid the more dramatic time dilation effects of higher relativistic speeds. However, such restrictions can be overridden at the behest of the ship’s captain.

5.3 Warp Drive

The warp drive on the Prometheus is a tetryon warp plasma warp drive system which operates in the same manner as non-Tetryon warp plasma warp drive systems execpt for the fact that Tetryon warp plasma is used instead of normal electro-plasma to generate a superior propulsive effect. When the Tetryon warp plasma is released into space it temporarily disrupts any warp field it comes into contact with, essentially "stalling" said vessel's warp drive which forces it to go to Impulse. The warp drive on the Prometheus is also augmented by the usage of Starfleet's most advanced design of Cerenkov emitters and the application of Quantum field assisted tetyron plasma technology which consists focusing a low power quantum field through the ship's main navigational deflector to generate minor changes in local space curvature which resulted in the Prometheus' cruising speed of warp nine and maximum speed of warp nine point nine nine requiring only sixty-one point five percent of the amount of energy that was required to maintain the same speed prior to the quantum field projection refit.
