An Urenbeck Catapult is a launcher that allows for practical travel within the solar system. It uses Metatron in its power train and works by compressing space and allowing the compressed space to return to its former state. Once the compressed space returns to its former state, the reactive force and buildup of potential energy enable the propelled object to travel "at sub-light speeds", according to Lloyd. The same principle is at work in the Zero Shift function.
Tremendous amounts electricity and power are necessary to activate the device, preventing its use for regular commercial purposes. Currently, the Catapult can be found at L2 on Earth and Deimos. There is also a catapult at the L2 on Europa near Jupiter, which is used as the gateway to the Anterior.
The name for the Catapult is likely derived from theoretical physicist George Uhlenbeck.
