Slip stream drive is comparable to transwarp technology. It has the ability to travel 60,000 light-years in 3 months. It was developed by an alien race of unknown origin recently assimilated by the Borg. Instead of using a standard warpcore, it is powered by a spherical device serving as its engine. Federation vessels, after certain adjustments, are able to harness slip stream speeds for a very limited amount of time. After a full integration into a Federation vessel's warp core, the sperical device is unneeded. The drive is much less limited with the new core, but much more unstable.
