Quantum slipstream driveedit this page

From Memory Alpha, the free Star Trek reference

The quantum slipstream drive is an advanced form of interstellar propulsion that achieved and exceeded what failed Federation attempts using transwarp were meant to do: exceed the warp speed barrier. Originally developed by an advanced species native to the Delta Quadrant, the technology was obtained by the USS Voyager in 2374 and used for an aborted test in early 2375 that nearly destroyed the ship.

The slipstream is a narrowly-focused, directed warp field that is initiated by manipulating the fabric of the space-time continuum at the quantum level. It works by focusing a quantum field through a deflector dish to generate massive changes in local space curvature; this creates a subspace tunnel, which is projected in front of the vessel. Once a ship has entered this tunnel, the forces inside propel it at incredible speed. In order to maintain the slipstream a ship has to constantly modify the quantum field with its deflector dish; however, the calculations involved are too complicated for 24th century Starfleet technology, and the time available is too short before the vessel out-paces the tunnel, collapsing the slipstream.

[edit] History

The Voyager crew first encountered slipstream technology when they found the USS Dauntless, a vessel ostensibly sent by Starfleet to transport them back to the Alpha Quadrant. However, the Dauntless was actually an elaborate trap set by Arturis to exact revenge on Kathryn Janeway for her role in the Borg's assimilation of his homeworld. In its first test by the Voyager crew, the Dauntless traveled fifteen light years in barely five minutes, about 1.6 million times the speed of light. During Seven of Nine's analysis of the technology, she commented on its similarity to Borg transwarp conduits, noting her expertise in the field and usefulness to the project. Voyager's chief engineer, B'Elanna Torres, temporarily modified Voyager's engines to be capable of slipstream flight, but in an untested state. Commander Chakotay brought these changes online during an attempted rescue of Janeway and Seven, but this implementation proved too much for Voyager's structural integrity to handle for extended periods of time longer than an hour. This limitation hampered Voyager's slipstream efficiency in comparison to the Dauntless – only after sabotage to Dauntless was Voyager able to intercept Arturis's ship. Voyager managed to traverse 300 light years during this initial operation. (VOY: "Hope and Fear")

Several months later, in 2375, Voyager's crew discovered some benamite crystals and used the rare mineral to construct a more advanced slipstream drive. However, Voyager's technology proved inadequate to the task of navigating the slipstream at the speeds generated by the engine – nevertheless, Voyager managed to travel nearly 10,000 light years before the slipstream collapsed. (VOY: "Timeless")

Later that year, the Think Tank expressed interest in trading for slipstream technology, despite its potential dangers. The group's representative, Kurros, considered it an "interesting puzzle." (VOY: "Think Tank")

[edit] Implementation

[edit] USS Dauntless

2374

Dauntless's quantum slipstream technology was intended to return the crew of Voyager to Borg Space. This was a non-Federation implementation, but allowed the crew an opportunity to study the drive for later implementation on Voyager. (VOY: "Hope and Fear")

[edit] USS Voyager

2374

Voyager's initial implementation of slipstream technology required the starship to accelerate via impulse power to slipstream velocity, causing extreme temperature stress to the hull before a quantum slipstream was opened. This slipstream was a separate conduit from the one created by an escaping Dauntless – Voyager required alignment calculations to merge the two slipstreams to travel to and intercept Dauntless. This merging also enabled Chakotay to fire photon torpedoes at Dauntless and utilize the transporter while in a quantum slipstream. (VOY: "Hope and Fear")

2375

During Voyager's second attempt at the technology, the ship's on-board sensors could not map the phase variances quickly enough for the engine to keep the slipstream stable. Ensign Harry Kim concocted a plan to fly the Delta Flyer ahead of Voyager, to accurately predict correct phase variances, and transmit the values to Seven for proper slipstream manipulation. Kim made incorrect calculations, resulting in the loss of Voyager on an ice planet a few parsecs from the Alpha Quadrant. In 2390 Kim unsuccessfully attempted to correct his mistake using a stolen Borg temporal transmitter, failing at his goal to alter the timeline with perfect calculations and return Voyager home. However, at the suggestion of The Doctor, whose program had been recovered from the wreckage of Voyager, he then calculated a phase variance to prematurely collapse the slipstream, saving the Voyager crew. (VOY: "Timeless")

[edit] Appearances

[edit] Apocrypha

The trilogy Star Trek: Destiny introduces the Vesta-class starships, a testbed for a Federation quantum slipstream drive, along with numerous other technologies. The new version of the drive proves to be successful, and in the novel Full Circle Starfleet mounts an expedition to the Delta Quadrant by outfitting Voyager and several other starships with a fully functional version of the drive.

In Star Trek Online, players are able to use a slipstream-generating device to transwarp back to Earth Spacedock.
