The Vulcan class colony ship was developed to carry entire human colonies through the skein and deposit them, along with their orbital habitat, in systems to be colonised. Able to carry about 100 000 people and all of their equipment, these vessels were huge and were the work horses of the corporate colonisation effort. In fact, it was estimated that almost 30 billion colonists were moved from the core system to the colonies using the Vulcan class over a 60 year period.
Colony ships carried no offensive weapons to speak of, although they were equipped with self-defence guns and carried several frigates and fighter wings that equipped the colonial militia.
Survey vessels are used by corporations to find mineral deposits on unsurveyed worlds and to locate possible sites for mining bases. Carrying a suite of highly advanced probes and scanners along with a crew of scientists, they are able to quickly and accurately survey uncharted regions of space and their trans-skein drives allow them to venture far beyond the rim.
Survey vessels carry several survey pods that can be manned or unmanned and although they have no offensive weapons, they do carry defensive weapons - rather using their speed to get out of trouble.
The Scythe fast corvette is a deep-space capable attack ship designed for planetary system patrol. Fast and agile, it packs an impressive punch with two raptor guns in single mounts and two double raptor and single lancer guns in composite mounts on either side of the hull. It also carries 24 disruptor missiles fired through four missile tubes in the nose and two in the stern. Crewed by 8 to 12 sailors, it is also equipped with an extensive array of planetary and orbital sensors.
Most Scythes are employed on the Rim in service of corporate navies, although some, inevitably, have fallen into pirate and marauder hands.
A merchantman concept from a few years ago. I started playing around with the idea of having ships that are broken up into elements that are held together by electromagnetic forces instead of having to be encapsulated in a hull. In this case, the ship has two drives (vertical wings) that hang on either side of the ship and propel it using dark energy drives.
Thirgen (Third Generation) ships are divided into separate units instead of the entire ship being encapsulated in a single hull. The ship is held together by powerful electromagnetic force generators which not only permit damaged or malfunctioning elements to be quickly and easily replaced but more importantly allow the ship to be realigned according to the situation it is in.
This Cavship (Cavalry Ship) is typical of thirgen designs, orientated around the chariot (cockpit) which is flanked by weapon pods (that can be moved along any axis; together or independently). Behind it is the spider (generator) and the drive ring that propels the vessel.
This segen destroyer is an example of the initial move away from unitary hulls to the completely "fragmented" design. The hull and primary weapon systems are integrated into the hull while the spider (power source with armoured cowling) and drive array are separate. When in combat, the ship also deploys weapon moons that encircle the ship and provide shielding and defensive fire.
