Quantum slipstream drive

**Quantum slipstream drive** was an advanced form of faster-than-light propulsion able to achieve speeds far greater than standard warp drive. The crew of the USS *Voyager* acquired the technology in 2374, during their sojourn in the Delta Quadrant. Their experiments with the drive allowed them to greatly shorten their journey, but use of the technology was put on hold when it nearly resulted in the ship's destruction.

## Functionality

The quantum slipstream drive operated by routing energy through a starship's main deflector, which then projected a quantum field, and allowed the vessel to traverse a quantum barrier into subspace. Maintaining the slipstream was difficult, as the phase variance of the quantum field needed constant adjustment, or else the slipstream would collapse, violently ejecting the ship back into normal space. Unlike traditional warp drive and similar FTL technologies, slipstream technology did not rely on matter/antimatter reactions; instead, benamite crystals were used to focus and control the energies involved. (VOY: "Hope and Fear", "Timeless")

Advanced computer systems, such as those integrating bio-neural circuitry, were necessary for implementing the technology. Generating slipstream corridors required more processing power than forming warp fields; the computational power required was directly related to vessel's subspace geometry. Therefore, slipstream propelled ships were generally narrow and compact with aerodynamic lines. Slipstream tech was far more energy-efficient than warp drive, which more than offset the increase in computer power. (*TNG* novel: *Greater Than the Sum*)

## Slipstream in the Alpha Quadrant

Starfleet Research and Development and the Starfleet Corps of Engineers began working on quantum slipstream drive in 2378, almost immediately after the USS *Voyager*'s return to the Alpha Quadrant. The USS *Spirit* served as an early testbed for the drive, though the technology's existence was kept classified for several years. Limited supplies of the necessary benamite crystals hampered the widespread application of the drive as well. Due to the nature of the quantum slipstream's interactions with subspace, there were many starship types whose hull design and warp field geometry were incompatible with the drive tech, including the *Galaxy* class, *Luna* class and *Sovereign* class and those with similar profiles. In contrast, *Intrepid*-class and *Prometheus*-class vessels were able to successfully implement slipstream drives.

### First Splinter timeline

By 2380, ships of the *Vesta* class were equipped with the technology, including the USS *Aventine*. The success of the drive on these vessels and others, led to the implementation of Project Full Circle, a long-term exploration and diplomatic initiative in the Delta Quadrant, led by *Voyager*. (*VOY* novel: *Full Circle*)

In 2382, a Breen operative infiltrated Utopia Planitia Fleet Yards obtain Starfleet's data on the quantum slipstream technology on behalf of the Typhon Pact. The Breen Confederacy's experiments with the drive came to an abrupt end a year later when their research outpost and prototype slipstream vessel were destroyed. The Typhon Pact abandoned further experimentation with the technology, seeing it as more trouble than it was worth. (*Star Trek: Typhon Pact* novel: *Zero Sum Game*)

### *Hidden Frontier* timeline

In 2384, armed with a new understanding of hyper-dimensional physics, Starfleet R&D was able to use material from the Grey tetrahedrons to power a prototype quantum slipstream drive aboard the USS *Odyssey*, enabling the vessel to travel to the Andromeda Galaxy. After *Odyssey'*s return in 2386, further refinements in the technology allowed vessels like the *Renaissance II*-class USS *Helena* to continue the exploration of Andromeda and other neighboring galaxies. (*Star Trek: Odyssey*)

### Hobus timeline

By the early 25th century, the technology had been refined significantly, and was widely implemented by Starfleet, the Klingon Defense Force, and the Romulans, to varying degrees. While the vessel's frontal geometry still played a significant factor, even ships that were formerly incompatible with the technology were able to travel some distance via slipstream, though the corridor was not sustainable for long periods. (*Star Trek Online*)

## Speed

When *Voyager* initially discovered the technology in 2374, it was projected that they could travel the remaining 60,000 light years of their journey in three months: an equivalent speed of warp 9.99992, or 243412.44 times the speed of light. Their starting distance of 70,000 light years would have taken about 105 days at that speed.

Subsequent testing of slipstream drive aboard *Voyager* performed at 2.63×106 (2,630,000) times the speed of light, or the rough equivalent of warp 9.99999275 (on the W10 scale). Had *Voyager* been able to maintain slipstream indefinitely at that speed they could have covered the original length of their 70,000 light-year journey home in about 10 days. As it was, *Voyager* managed to travel 300 light-years in the hour before they were forced to shutdown the drive. (VOY: "Hope and Fear")

At that speed, it would just under a year (~355 days) to cross the intergalactic void between the Milky Way and Andromeda, almost three hundred times faster than the projected voyage of the Kelvan-modified USS *Enterprise* in 2368. (TOS: "By Any Other Name")

During the Archein invasion of the Beta Quadrant in 2384, the USS *Odyssey* (NCC-81302) and the IKS *R'kog* were outfitted with slipstream drives in order to find and destroy the Archeins' artificial wormhole in Andromeda. Using material from the ancient tetrahedrons found in the Briar Patch to augment the drives, *Odyssey* and *R'kog* were able to make the journey to Andromeda in just two weeks. Unfortunately, *Odyssey* was forced to sacrifice their slipstream core in order to disable the wormhole generator complex, leaving them stranded. (*Star Trek: Odyssey*)

The more stable, though slightly less powerful version of the slipstream drive incorporated into *Vesta*-class starships during the 2380s and 2390s produced speeds equal to Warp 9.999993, or 310.08 light-years per hour. (STA: *Utopia Planitia Starfleet Sourcebook*)
