Starship Design in the Archaic Era(3 - 4)
Ships of this era were just beginning to be practical vessels for sustained interstellar exploration, commerce, and combat. Ships built at level 3 still relied on heavy armour for both function and reassurance, as the grav shield system was relatively new and untested. Grav drives were commonplace and warp drives became so by the end of the era.

Starship Design in Antiquity (5 - 6)
Post modern ship design reflected an era of growth and conflict. Established and growing empires were developing technologies at an astonishing rate, power was plentiful through new technologies like rotated particles and singularity generators, and travel was swift and sure with skip drives on most ships and string drives appearing with regularity. New weapons and defenses developed constantly and everyone wanted to try out their new toys on old enemies. It was not until late in the era, when economies started to slag and resources started to dwindle, that the empires began to see the impossibility of prolonged conflict between distant worlds.

Modern Starship Design( 7 )
With the sheer number of huge corporations producing reasonably priced ships, specialized ships are more common than in the past. Beyond the freighters and military craft of the past, specialized cruise ships, personal and corporate craft, and a variety of other scientific and commercial craft appear constantly. The advent of neuralink control and the smaller required crew compliments has opened up a lot of space, leading to better crew appointments or significantly smaller ships.  With a thought to the conflicts of Antiquity, most modern ship design incorporates at least some defensive capabilities.

Starship Sizes
Starships are huge. They house an assortment of enormous equipment, including power reactors, one or more star drives, a variety of weapons, and communications and computing equipment. They also need living and entertainment space for crews. So you can forget any notion of star-fighters the size of F-16s. This section is an attempt to work out reasonable relative sizes of various ship hulls and can be used as a good proportion guide for artists..
