Ark Mechanicus hull

Over many millennia, a large number of star vessels of various hull designs, fitting no specific classification, have been seen bearing the insignia of the Adeptus Mechanicus. Many of these ships are incredibly ancient vessels, possibly recovered space hulks, re-commissioned so as to examine their characteristics under normal operation.
A notable few of these are the unimaginably vast, almost mythical Ark Mechanicus vessels, said to endlessly ply the stellar maine in the Quest for Knowledge. These vessels are rarely encountered by others as they perform their missions in the service of those who give life to these behemoths of the stars. Such vessels are said to predate even the Great Crusade.
Some have suggested that aspects of its design were lent to both the Retribution battleship as well as the Victory battleship most commonly encountered in Segmentum Tempestus. The Adeptus Mechanicus have not been forthcoming regarding the veracity of this information.
