Intrasystem jump drive

For subspace travel via jump nodes between star systems, please see intersystem jump drive.

An intrasystem jump drive is a standard subspace drive, developed before intersystem drives and present on most fighters at the onset of the Great War.

Intrasystem jump drives enable a ship to jump from one location in the system to another, quickly and (relatively) precisely. A jump drive of this kind does not need an intersystem subspace node, only the presence of a significant gravity well, precluding travel outside the boundaries of a solar system.

While subspace travel from one system to another in an intersystem jump takes a variable but relatively brief amount of time (the Lucifer's transit from Delta Serpentis to Sol took fifteen minutes), an intrasystem jump is described as "nearly instantaneous."
