[Warhammer40K] How long does the Journey of An orc spacecraft take?

For example if ORCs would have a legendary WAAGH, with tens of thousands of spacecrafts and a mothership like the space hulk. How long would these ship hop from system to system? I haven't read anything about them using warp drives etc. Or did i misread and do they have some kind of way to Traverse the warp?

They do use Warp technology. It's crude, but shockingly effective - and being orks, they are notable for being on e of the few factions crazy enough to bring it to the battlefield, in the form of the Shokk Attack Gun, which fires snotlings through the Warp to materialise inside their extremely surprised target.

Their standard mode of travel is a Space Hulk or Rokk (basically an asteroid with a warp drive nailed on), which travels through the Warp fairly randomly; unlike humans, they don't bother with protection from the entities that dwell within the immaterium, because they're A) functionally immune to daemonic possession and B) always up for a scrap if any daemons feel like climbing aboard their ship.

Ork navigation would appear to be nonexistent, but probably functions as an extension of their powerful gestalt psychic field - the thousands or millions of orks on the craft *believe* that they are travelling to a good fight, and thereby subconsciously navigate their way to a location where there's somebody worth having a go at.
