This hive fleet is scouting various system, with [[vanguard drone shipVanguard Drone Ship]]s that have been found in over 20 systems. When the Tyranid Hive Ships enter a system they immediately assault any habitable planets, while ignoring any Imperial space stations and outposts on otherwise barren planets and moons. Imperial vessels have only been attacked after they directly engaged the Tyranid void travellers. These are a few of the reasons why the Achilus Crusade believe that the [[Hive Mind]] is operating in a conservative fashion or unable of identifying these as worthwhile targets. On [[Castobel]], [[Atonement]], and [[Hethgard]], Imperial defenders managed to repel enough of the spores that the battles for control of these planets have become protracted engagements. On [[Avalos]] and [[Treyen]], Imperial defenders even managed to repulse the initial Tyranid attack, causing the void-faring Tyranid creatures to leave those systems. {{Fn|2}}
