Navis Imperialis - Cruiser: Cruisers make up the majority of an Imperial Navy fleet. Though not as powerful as a Battleship, Cruisers are much faster and can still deliver a deadly blow. There are multiple classes of Cruiser, most based on the same general hull design but incorporating different combinations of broadside batteries, Lance turrets and Attack Craft hangars.Examples include the all-round, ubiquitous Lunar-class, the Gothic-class with its powerful Lances and the Dictator-class Attack Craft carrier. Cruisers can carry a crew complement of anywhere between 10,000 and 1,000,000 crewmen (including Imperial Navy armsmen and military police squads), depending on the sources consulted.While Cruisers are still particularly technologically complex, it is not uncommon for them to be constructed on smaller Forge Worlds or any Civilised World that has an orbital shipyard suitable for constructing vessels of their large size. Of particular note was the Lunar-class Cruiser Lord Daros, constructed in orbit above the Feral World of Unloth in 11 Terran years by relying on the forced labour of most of that planet’s population for materials.A note on Imperial warship classes: while naval warships can be defined along a fairly limited number of classes based on weapon configurations approved by the Adeptus Mechanicus, the physical form these vessels take varies widely throughout the Imperium.For example, a Lunar-class Cruiser constructed above Cypra Mundi in the Segmentum Obscurus may bear little resemblance to a Lunar-class Cruiser constructed above Kar Durniash in the Ultima Segmentum and even less so to a Lunar constructed among the vast shipyards of Mars' Ring of Iron. Nonetheless, they will all have roughly the same operating characteristics and weapons configuration, and thus can be easily serviced by any orbital facility throughout Imperial space.Note there are also classes of Battlecruisers. Although based on a hull-design that is similar to the regular Cruiser types, these starships are generally somewhat larger and more heavily armed, incorporating more advanced power distribution systems capable of supporting Battleship-grade weaponry in a Cruiser hull. A notable example is the Mars-class Battlecruiser, with its fighter bays, broadside batteries, dorsal Lance turrets and an immense, prow-mounted Nova Cannon capable of attacking targets at extremely long range.A subset of the Cruiser type is the Light Cruiser. These warships fall in size between Cruisers and Escorts, mixing the firepower and durability of the former with the speed and manoeuvrability of the latter. The Dauntless-class is a very common Light Cruiser class in the Imperial Navy. Extremely self-sufficient, it is fast and has enough firepower to be a threat to Escorts and larger capital ships alike.There are other classes of Light Cruiser in common use in the Imperial Navy, most notably the Endeavour-class, which serves in varied forms and hull types throughout the Imperium. Light Cruisers are a fairly common warship class, for they are relatively simple to construct for a capital ship, and they are uniquely suited for reconnaissance patrols and for ensuring a presence where their speed and manoeuvrability are an advantage, and where having a larger number of smaller hulls allows the Imperial Navy to monitor a wider area of space.
