"I have fought alongside them in battle and the Dark Angels have always had their own agenda. They are arrogant and pig headed and don't know how to relax when the fighting is over. They feel no shame in having insulted my Primarch. However, they are my battle brothers. And I would want them at my back when the Despoiler brings his Black Crusade to the Imperium again.
-Wolf Priest Gunnar Hamundarson
The Dark Angels are one of the few Space Marine chapters that have no planet to call home. Thus their ships become the home they no longer have. They are constantly in use and for this reason must be kept in perfect working order at all time.
