Intrasystem jump drive

The first intersystem jump drive is even older than the first subspace drive; it was present during the post-age of space exploration and colonization.

Intersystem jump drives enable a ship, initially not smaller than a freighter to jump from one location of the system to another, quickly and precisely. A jump drive of this kind does not need a subspace node to operate, for the simple fact jump nodes lead to another system and intersystem jump drives, as their name indicates, can only be used within system.

Before the end of the Great War, no ship of equal size of a fighter or bomber could produce enough energy to operate an intersystem jump drive. When the Ancient ruins were being extracted, Terran fighters used intersystem jump drives to help assist the GTSC Rossetta while she was transfering xenolinguists to Altair to help and examine the ruins that the Vasudan refugees of Vasuda Prime found.

While a subspace travel from a system to another in a subspace tunnel takes ten or even more minutes, an intersystem jump takes no more than one or two minutes, depending on the distance to take, sometimes even less.

Intersystem jump drives also enable ships to navigate inside subspace and track down targets within it. This advantage allowed the Galactic Terran Alliance to track and hunt down the SD Lucifer before she could have extinguished all life on Earth.
