Dredger J-403 was built in 3088, but remained fully operational over two centuries later in 3307, and synthesised the fuel and other resources it needed by taking in and converting raw and salvaged materials from planetary rings and derelict ships.

Dredger drivesĭredgers utilised a type of hyperdrive that was a contemporary of the quirium drive, but did not consume specialised quirium fuel. With all quirium drives no longer usable, faster-than-light travel reverted to slower and more primitive methods. After GalCop dissolved in 3174, the secret formula necessary to manufacture quirium fuel was lost, and the hyperspace industry suffered a major setback. The Faraway Jump was known for its delicacy, however, and depended on a complex network of monitoring satellites, branch lines, stop points, and rescue stations, all of which took centuries to establish, in order to operate smoothly. It was powered by a fuel called quirium, an energy-dense material exclusively produced by the Galactic Cooperative. This model had a relatively short jump range, but travelers spent only a brief time in hyperspace with each jump. The first commercially-available hyperdrive was the Faraway Jump, introduced in the 2800s. Until the 2800s, hyperdrive technology was mainly only available to corporations and governments, similar to how affordable starships were also beyond the reach of consumers until the introduction of the Python in 2700. Early hyperdrive models based on the Li Qin Jao design were slow and inefficient, but exponentially faster than sublight travel, which thousands of Generation Ships were forced to rely on. A team of engineers led by Li Qin Jao invented the first hyperdrive in the 22nd century.
