Power and Propulsion

Power and Propulsion

This field covers all technologies related to engines, reactors, jump drives, fuel efficiency, thrust modifiers, and other systems that determine how ships move, jump, and generate power.

Jump Drives

Commercial Jump Drives are larger, less efficient and cannot be used by ships with military engines.

Jump Point Theory

Precursor technology for the various jump drive technologies.

Tech	Jump Point Theory
Value	0
RP Cost	5000

Jump Drive Efficiency

Jump engines with higher levels of jump drive efficiency will permit larger ships to jump than lower efficiency engines of the same size. Ships with military engines are unable to traverse a wormhole created by a commercial jump engine and vice versa.
