=Ship Technology=

Grav Plates
The most important artifact retroengineered. Provides 1G environment aboard a ship. Can't be mounted on ships larger than a certain size (depending on grav plate quality).

=Drive Technology=

Plasma Injector (HEPlaR)
Hydrogen is injected into a fusion reactor compressed in a magnetic bottle and ejected as high energy plasma at high velocities. Normal military interplanetary drive. Can also double as a CoSRat Engine.

Combination Scram/ram/turbojet Engine (CoSRat Engine)
Interface drive that goes from Scram to Ram to turbojet at different speeds with varying magnetic bottle configurations.

Slingshot drive
Ships are cast from here to there. Slingshots always take up to several weeks to perform but can be made with external, static jump engines that speed the process to a couple of days. The largest such station is located out on the Solar rim, hidden on Io. The ship-mounted Slingshot Drive produces a field with a radius proportionate to the engine mass, that jumps everything within its reach. Outside that the fabric of reality quickly oscillates and produces intense wakes, which rips apart everything out to about triple the field radius. The energy is most often generated by several huge fusion reactors, and stored in storage tanks while spooling up. The Slingshot Drive picks up momentum as it passes by gravitational fluctuations, so most primary jumps between stars have endpoints outside of any gravitational wells.

Io
The only naval base and home to the UN Fleet.

Proxima Centauri
The only functioning ecosystem besides outside the Solar system.

Wolf 359
Economic failure. Now one of the continents of Wolf 359 is a prison. Superstorms and regular tsunamis after failed terraforming attempt.

Lalande 21185
Frontier planet. Exosuits needed.
