The Stardrive is an advanced unit you can build that will enable your capital ships to travel at tremendous speeds. It's basically a carrier - you move a ship onto the top of the stardrive, then select the stardrive unit itself and move it around. Both of the ships will travel at great speed to wherever you click the mouse, just like a regular unit.

Here's some things to remember when using the Stardrive unit.

* Units docked with it do NOT get repaired. The stardrive is not a repair vessel!

* You can have a unit fire from the back of a stardrive by setting it to 'hold position'. This can make battleships move like grease lightning and still fire as they want.

* Damaged units on patrol will not automatically dock with the stardrive like regular carriers.

* Anything docked with the stardrive can detach at any time and move around normally.

* When a unit detaches, it will decelerate to it's regular top speed at it's normal braking rate. For battleships, this can mean 30 seconds of incredible speed after detaching while still in motion.
