This subsystem is obsolete and has been replaced by newer technology This subsystem exploits the latest technological advances afforded by discovery of the ancient Sleeper race's own designs. Optimizations made to the chassis allow for vast improvements to be made to a Legion's base velocity. Although the various layout optimizations sacrifice other options for propulsion customization, the flow-on effects from an increase in base velocity make it an attractive upgrade for those whose Tech III vessels are in need of an overall speed increase. Subsystem Skill Bonus: 5% bonus to max velocity per level.
