Cetaceus Class Transport
The Cetaceus-Class Transporter or the Whale as it is sometimes referred to, is an Imperial vessel used exclusively by the Imperial Guard to transport manpower and equipment from battlezone to battlezone.
Like other deployment/carrier vessels, whaleships can carry upwards of a single regiment of Imperial Guard units with all associated equipment and vehicles. However, they are unique in that the associated guard units are not actually held within the vessel itself at all, but within specially designed interplanetary dropships that are stored within the hull, ready to be launched when the carrier reaches position. The whaleships; are also capable of carrying all of their own support craft, from Minotaur-class Tug vessels, Devourer Dropships, and strike craft. Deploying them from the a large open launchbay at the fore of the vessel in addition to the dropships. Unlike the launch bay on more common Imperial carriers, the support craft are stored within three massive decks which are exposed to the vacuum of space. Therefore each support craft self-sufficient and is dependent on the carrier only for warp travel from location to location.
The Cetaceus itself is particularly well armoured, and as much of its hull space is taken up by empty storage it is capable of operation even after massive hull damage (up to 75% structural damage has been noted with continued operation)
