Hive Fleet Dagon
Hive Fleet Dagon was the first major Tyranid incursion into the Jericho Reach region of the Ultima Segmentum. The Shadow in the Warp cast by the Tyranid Hive Mind within this volatile region of space first heralded the arrival of this new and terrible Hive Fleet in 812.M41. Communication between parts of the Achilus Crusade and the re-conquered regions of the Jericho Reach was lost without warning. Particularly affected was the Orpheus Salient of the Crusade that was lost to communication and access with the rest of the Reach behind the Hive Fleet's crawling shadow of Warp interference.
Hive Fleet Gorgon
Hive Fleet Gorgon was a Tyranid Hive Fleet which invaded the Tau Empire in 899.M41. The Gorgon was a splinter fleet of Hive Fleet Behemoth that had been founded by those Tyranids who had survived the Behemoth's destruction during the Battle of Macragge and which began consuming poorly defended Imperial worlds to replenish its small numbers. By the time this splinter fleet made its way into Tau space in the Eastern Fringe of the galaxy, it had grown to become a full Hive Fleet in its own right.
Hive Fleet Leviathan
Hive Fleet Leviathan was the third and largest Tyranid incursion into the Milky Way Galaxy in 997.M41 and marked the start of the ongoing Third Tyrannic War for the Imperium of Mankind. Less than five years after the defeat of the Hive Fleet Kraken in the Second Tyrannic War, Lord Inquisitor Kryptman noted the tell-tale signs of yet another Tyranid invasion in 997.M41. He implemented the Kryptman census, burning out dozens of astropaths in the attempt to contact scores of worlds on every fringe of the Imperium. Slowly, the responses - and lack of them - formed a pattern, and the venerable Inquisitor was able to chart the course of the Tyranids' latest Hive Fleet to arrive in the Milky Way Galaxy.
Hive Fleet Behemoth
Hive Fleet Behemoth was the first major Tyranid Hive Fleet encountered and defeated by the Imperium of Man. The ensuing conflict became known as the First Tyrannic War. The Hive Fleet was eventually destroyed in 745.M41 by the combined might of the Ultramarines, the White Scars, and the Imperial Navy.
Hive Fleet Kraken
Hive Fleet Kraken was the second major Tyranid Hive Fleet to invade the galaxy. It was responsible for the outbreak of the Second Tyrannic War, which began officially in 992.M41 and ended only after the Ultramarines Chapter of Space Marines successfully broke the back of the Tyranid invasion in Imperial space at the Battle of Ichar IV and the Eldar of Craftworld Iyanden successfully defended their home, at great cost, against the Tyranid horde.
