Looted asteroids!!! No, really, that's it.

Even among Ork vehicles, Roks've little in the way of standardisation. They can be of any size, ranging all the way from small asteroids to small moons, depending on what celestial objects the Orks can get their mitts on. Natural craters and caves're expanded upon and new ones're excavated, opening up vast warrens of tunnels and chambers beneath the cold exposed surface, housing crew quarters, engine rooms, and gun batteries. They're incredibly easy to make, only requiring the level of expertise necessary to make terrestrial bunkers, and thus flotillas of them spring up in every system Orks come to.

Roks had a lot of Special Rules because of their unique nature, but we'll get to those later. A Rok was Defence/8, with a single Gunz Battery, Heavy Gunz Battery, and Torpedo Launcha, all three of which had All Round Fire Arcs, and the Gunz Battery got the 45cm Range and 1d6+6 Firepower of a prow weapon. It had to move its maximum Speed of 10cm forward in a straight line, and couldn't turn at all. Yes, you heard that right, it couldn't turn! That meant it couldn't use the Burn Retros or Come To New Heading Orders either. The only way to change direction was with the All Ahead Full Order, which let it move in any direction an extra 2d6cm, and if it moved more than 10cm in a different direction to the one it was previously going in, that became the new direction of travel. Roks didn't reduce their Speed when Crippled or moving through Blast markers.

You also didn't roll on the Critical Table when Critical Hits were scored against a Rok, each Crit just inflicted an extra point of Damage. And when a Rok was finally destroyed, it automatically broke up with no need to roll for Catastrophic Damage, being replaced by 4 Blast markers.

As many Roks could be fielded in your fleet as you wanted, just like Escorts, and each only cost as much as two Ork Escorts, so you could quite easily swamp the enemy in your own mobile asteroid field. Their rules made them a right pain to fight, as you couldn't predict where they'd go with any degree of certainty, and each came with a lot of weapons for their price.

Roks'll often be deliberately crashed into a planet's surface when the Orks're invading, and they're reinforced enough to actually survive the impact, dislodging their passengers like giant Drop Pods. If your ground forces didn't come by Landa or Tellyport, they came by Rok.
