Editing Space Marine Battle-barge (section)

===Bucephelus===

The Bucephelus is a giant, golden Battle Barge used by The Emperor himself as his flagship during parts of the early stages of the Great Crusade. It was apparently so large, that it generated its own gravity field.

One of the 3 vessels known to have been the Emperor's flagships, he eventually dumped the Bucephelus and used the Imperator Somnium as his flagship, which was ''even larger''. Despite its sacred history as being the personal steed of The Emperor himself and one of the Mechanicus' priceless works of art: nobody knows what happened to it, as if The Emperor just dumped it in a space parking lot somewhere and left it to rot while cruising in his new ride. However, considering the Imperial precedent for [[The War of The Beast|ignominious defeats]], if it ever were lost in battle, it's even odds that everyone would just [[Lost legions|agree not to talk about it]]. This is probably the case as even by the Siege of Terra series it remains unmentioned, unlike the aforementioned ''Imperator Somnium'' (which the Siege of Terra reveals that it was still in use by the Siege of Terra and was used as a massive [[DISTRACTION CARNIFEX|distraction carnifex]] to cover Corswain's Dark Angels' landing to retake the Astronomican). Its exact size isn't known but considering that it mounted 10 [[Nova Cannon|Nova cannons]] on its prow - when even Battleship-sized craft can only mount one - it's got to have been pretty huge.

Confusingly, it has been described as having been created on Terra before the Crusade even started.
