IMPULSE DRIVE SYSTEMS
THE ORIGINAL SERIES
System:
Scarbak Propulsion Systems RAA
Ships:
Enterprise (NX)
Description:
Scarbak of Cairo, Egypt has a long history of supplying fusion power plants for Earth starships since the mid-2000’s. When it came time to develop a fusion-powered impulse drive system for the NX class, Scarbak was a natural choice as prime contractor.
System:
Scarbak Propulsion Systems RAB
Ships:
Daedalus
Description:
The RAB was a refinement of the RAA from the NX class, designed for the heavier displacement of the Daedalus class.
System:
Scarbak Propulsion Systems SBA
Ships:
Constitution, Bonhomme Richard
Description:
The SBA series were designed for vessels massing over 150,000 metric tons and saw service with the Constitution and Bonhomme Richard classes.
System:
Scarbak Propulsion Systems SBE
Ships:
Coronado, Achernar, Surya, Coventry, Endeavor
Description:
The SBE was designed for ships massing under 150,000 tons, but further enhancements to the basic design eventually made it suitable for vessels up to 200,000 tons.
THE MOVIE GENERATION
System:
Scarbak Propulsion Systems RSM
Ships:
Enterprise, Federation (II), Ascension, Constellation
Description:
The RSM series was a major leap forward in impulse engine design. It was directly connected to the warp core through the primary intermix shafts, with warp power being deflected by a crystal into the impulse system. This resulted in significant improvements in both thrust and sublight acceleration for vessels massing over 200,000 tons. It debuted first on the Enterprise class and soon became standard on most starships of the era.
System:
Scarbak Propulsion Systems Namada NK
Ships:
Constitution (II)
Description:
Used only in the Constitution (II) class CH, this system requires four engines, as opposed to the two of the RSM. Though more complicated, this results in above-average performance.
System:
Scarbak Propulsion Systems RSL
Ships:
Belknap, Tikopai
Description:
The RSL system is a slight refinement to the RSM. Performance is slightly lower, while maintenance is slightly less. Used in the Belknap and Tikopai classes.
System:
Scarbak Propulsion Systems RST
Ships:
Avenger, Daran, Knox, Endurance, Cyane
Description:
The RST was designed to provide the performance benefits of the RSM system at a lesser price for vessels displacing less than 200,000 tons. It is used mostly in frigates and destroyers.
System:
Scarbak Propulsion Systems SANTH
Ships:
Enterprise (II)
Description:
The SANTH system is a design improvement to the RSM. Using an expanded impulse deck with direct-firing ports, it improved performance of the RSM by some 15%.
System:
Scarbak Propulsion Systems SANTH-H
Ships:
Excelsior, Ingram
Description:
The SANTH-H (for “Heavy”) was designed for large vessels in the million-ton range. Previous ships (such as the Ariel and Fredrickstaad) required two or more impulse systems. It’s use was limited to the Excelsior and Ingram classes.
System:
Orage Ijek “Delrum” CCE
Ships:
Akyazi
Description:
Orage Ijek of Andor was the first company to successfully break the impulse drive monopoly of Scarbak with the CCE. Compact and powerful, it was a perfect match for the Akyazi class PA.
System:
Orage Ijek “Delrum” CME
Ships:
Arbiter
Description:
The CME series offered more power and better performance than the CCE, and was fitted to the follow-on Arbiter class PAs.
System:
Orage Ijek “Delrum” CME-A
Ships:
Akula
Description:
A further refinement, the CME-A was designed to provide still more power to augment the additional defensive systems of the Akula class PA.
THE NEXT GENERATION
System:
Kloratis FIG-1
Ships:
Ambassador
Description:
As Leeder had done with the LF-10, Kloratis drives of Tellar landed their first Star Fleet contract with the Ambassador class. Kloratis specialized in impulse drives for superfreighters and tankers that often exceeded two million tons. However, the sheer mass of the Ambassador required Kloratis to integrate a space-time coil to effectively “lower” the mass of the Ambassador by a million tons.
System:
Kloratis FIG-2
Ships:
Norway, Steamrunner, Cheyenne, New Orleans
Description:
The successful integration (and patenting) of the space-time driver coil effectively made Kloratis the only choice for Class One starship impulse drives. The FIG-2 provided the same performance of ships between one and two million tons that the SANTH-H did – at about half the cost.
System:
Kloratis FIG-3
Ships:
Saber, Defiant, Nova
Description:
The FIG-3 brought the benefits of the FIG series to vessels between 300,000 and 700,000 tons.
System:
Kloratis FIG-4
Ships:
Akira, Intrepid
Description:
As starship designs grew bigger, so did Kloratis drives. The FIG-4 was the first drive certified for ships greater than four million tons.
System:
Kloratis FIG-5
Ships:
Galaxy, Galaxy (II), Nebula, Olympus, Courageous, Peacekeeper, Flynt, Maxwell, Sovereign, Prometheus, Delphis, Delphis (II), Entente, Griffon
Description:
When the Galaxy class CKE was expected to mass some 4.5 million tons, Kloratis improved the output of the FIG-4 to meet it. The FIG-5 is certified for vessels massing up to six million tons, depending on the number of exhaust ports and reactors.
