Shaw-Fujikawa Translight Engine

The Shaw-Fujikawa Slipspace Drive was developed secretly by a group of military researchers in 2291.This motor is capable of Slipspace jumps of hundreds of thousands AU(Astronomical Unit) to other Colonies in months. "Short" jumps routinely take up to two months, and "long" jumps can last six months or more. Shaw-Fujikawa engines allowed UNSC ships to leave normal space and plow through a dimensional subdomain colloquially known as "Slipstream space".

The Shaw-Fujikawa drive of the Humans "forces" its way into Slipspace by using brute force. The Covenant on the other hand slice open Slipspace and are therefore much more accurate when it comes to Slipspace jumps. In Halo:First Strike, captured covenant engineers made the Gettysburg the fastest ship in the UNSC, by upgrading its Slipspace drive.

The drive is explained more indepth in Halo: Ghosts of Onyx on page 53.

Quotith Page 53, Ghosts of Onyx: "Shaw-Fujikawa engines allowed UNSC ships to leave normal space and plow through a dimensional subdomain colloquially known as "Slipstream space." ... The drive used particle accelerators to rip apart normal space-time by generating micro black holes. Those holes evaporated via Hawking radiation in a nanosecond. The real quantum mechanical "magic" of the drive was how it manipulated those holes in space-time, squeezing a hundred-thousand-ton cruiser into Slipspace."

A damaged Shaw-Fugikawa Slipspace Drive was used to make the armor of Spartan-051 malfunction and send him flying into unknown space, so that he could be rescued, and then recommissioned to train the new Spartan-IIIs.
