Warp Speed Table

This table is based on the Star Trek:Voyager Technical Guide v1.0 which is copyrighted material of Paramount Pictures, Inc.

†Pi band of d-warp is well above anything that is survivable by an inhabited vehicle, but hyperwave pulse generators can now push a data stream through this band of hyperspace, allowing vastly improved communications times between bases separated by large distances. Because of the targeting needed, delays for starships using hyperwave radio are correspondingly longer since they need to transmit to a known fixed point and then allow that fixed point to transmit to another fixed point which can establish a link with another moving target. In practice, this means that vessels at distances of greater than 20 LY from each other can never have real-time conversations.

Note: "Full impulse" usually refers to an acceleration, not to a fixed speed. The term has been changed to "impulse cruise" above from the original text. The value can be used as a reference for quarter lightspeed which would be achieved after some time under impulse acceleration and with only minor relativistic effects (and those you'd find messy).

Second Note: This is technobabble. Do not use this in physics exams.

Third Note: Thanks to Michael Okuda and Rick Sternbach for figuring this out. Jari Makela for replacing miles with kilometers. Jeffrey Jenkins for expanding the chart to include more warp values and hyperspace values specific to ASR. Graham Kennedy for his Daystrom Institute Technical Library page where Henning Rogge's warp formula, which was used to make these calculations, was located.
