Forge World contradiction?
Extermination says like below;
"The Imperial Fists' naval might was the greatest of any of the Legiones Astartes, and was further enhanced by the fact that many of the ships were the largest in the Imperium. Even the Sons of Horus and the Ultramarines could not rival such strength alone."
However according to Tempest ...
''The main body of the Legion's void craft fleet was then made up of mid-scaled cruisers and smaller Battle Barges of various classes, along with substantial numbers of lighter pattern purpose-built Strike Cruisers, frigates and fast patrol cutters, all which could be produced by the shipyards of worlds across Ultramar. Although this fleet structure did allow the Legion a great deal of flexibility and range in how it deployed its many Space Marine chapters, its combined overall tonnage and firepower ranked the Ultramarines fleet in the mid-tier of the Legions, considerably behind the Imperial Fists, for example, and behind the Death Guard in terms of number of heavy capital units.''
Really, what it indicates? Why FW has engendered such inconsistency?
