Technology is cyclical. Over the course of the last 10,000 years the Galaxy has discovered and invented just about all there is to invent and improved designs just about as far as they can be improved. Everything is enslaved to the laws of physics (even Star Wars physics). Only tastes change over time.

By this era in the Star Wars history, 1000 years before the Imperial Era, most every technological item available during the Imperial Era is available here. There has been minor advancement of the overall technology level, but the pace of advancement in the Star Wars universe is slow, probably hampered by the high cost of making even the smallest change at this high of tech level.

Most of the common starships designs seen during the Imperial Era are available in some form during this era. However, due to some technological advancement, some adjustments need to be made when adapting statistics. For example, if a player wishes to use a YT-1300 in this campaign, some adjustments need to be made.

First: Rename the vessel. Use an earlier designation. YT-1000 works in this instance.

Second: Double the Hyperdrive multiplier. Do to differences in Hyperspace Technology over the past 1000 years, all starships during the Legends of the Old Republic era have slower hyperdrives. If the YT-1300 had a x1 hyperdrive, it's x2 in this era. It's x8 backup becomes a x16 backup in this era.

Third: Reduce the Space Movement by 10%. A Space Move of 7 becomes 6.

Other modifications might, but not neccesarily have to, include reducing Shield effectiveness, Weapon performance, or increasing crew requirements due to less automation.  Weapon damage should remain the same, but ranges or Fire Controls might be reduced.

In this era, there are no Star Destroyers or Nebulon-B frigates or X-Wings, not even Z-95 Headhunters or Dreadnaughts, but by simply rearranging some stats and giving the vessels new names, contemporary analogs of these vessels can be made that fit nicely in the setting and fulfill the same roles and functions as their descendents.
