Lord Zack's Space Opera
Hyperdrive is largely a lost technology in the Milky Way Galaxy. Warp Drive is far more common and easier to use. The United Federation of Planets has only a handful of ships that are even compatible with the few hyperdrives they have, and they are usually not installed. The arrival of the Galactic Empire to the Milky Way has changed things. Their hyperdrives have the potential to be far more easily produced by the races of the Milky Way, yet they have limitations not present in the Asgard hyperdrives given to humans by that race. These include the necessity for astrogation data to safely travel.
