Tarkin's Gambit: The Vader Contingency
a vessel designed for interstellar travel
Starships were commonly powered by ion engines, the most common form of sublight drives, and many—usually the larger vessels—were equipped with hyperdrive generators, used to reach hyperspace as lightspeed would not be fast enough. Light-years would take years to travel across using sublight drives. Across the galaxy, many starships were armed, usually with laser cannons. Capital ships often featured turbolaser emplacements or missile launchers, and some featured hangar bays that could carry starfighters.

Intergalactic starflight became possible with the invention of the dual-drive system, which included an anti-grav drive to exit a system’s gravity well, allowing inter-system travel, and a hyperdrive system for faster-than-light travel.
For the first 21,000 years or so of the Galactic Republic, hyperspace coordinates were plotted with the aid of hyperspace beacons, space stations placed in open space, distant from gravity wells, where ships would download data provided by the Republic Spacelane Bureau. Around the time of the Mandalorian Wars, navicomps replaced the beacons, making hyperspace navigation much more autonomous.
