Afterburners (AB) and Microwarpdrives (MWD) are the most commonly used propulsion modules. Afterburners increase the ship's maximum speed by around 150%, while Microwarpdrives increase it by around 500%. Compared with Afterburners, Microwarpdrives use more capacitor energy, reduce the ship's total capacitor capacity, increase the ship's signature radius when active, are shut down by [[scram|warp scramblers]], and are generally harder to fit.
Afterburners (AB) and Microwarpdrives (MWD) are the most commonly used propulsion modules. Afterburners increase a ship's maximum speed by around 130-200%, while Microwarpdrives increase it by around 500-700%. Compared with Afterburners, Microwarpdrives use more capacitor energy, reduce the ship's total capacitor capacity, increase the ship's signature radius when active, are shut down by [[scram|warp scramblers]], and are generally harder to fit. When active, afterburners and microwarpdrives also increase a ship's mass, making it less maneuverable.
 
Afterburners and microwarpdrives each have 10 second cycle times, and cannot be deactivated prematurely. However, the cycle time of afterburners can be reduced to 7.5 seconds by their skill. Capital ship-sized afterburners and microwarpdrives in stead have 20 second cycle times.


The 500% signature radius penalty of a microwarpdrive means that a ship using one will need to fly 500% faster than normal in order to effectively dodge enemy weapons fire. While the microwarpdrive's 500% speed increase may look like it cancels this out, this is deceptive. As a result of acceleration, turning, and orbiting, a ship with a microwarpdrive will very rarely be flying at speeds approaching the 500% bonus the drive gives, while they will be suffering the 500% signature penalty regardless of their speed. Consequently, while microwarpdrives are very good at allowing ships to control their engagement range (and either increase or decrease the distance between themselves and their enemies), they are not very effective at helping evade enemy weapons damage. Meanwhile, while afterburners are less effective at range control, their straight speed increase makes them very effective at helping evade damage.

In practice, that last thrust/mass term is almost equal to one when using properly sized modules on Frigates, Cruisers, and Battleships; and the ship's new maximum velocity is just its base velocity multiplied by the bonus of the propulsion module. However, certain exceptionally light-weight ships (like many Triglavian ships) can achieve higher speed bonuses; and heavier-weight ships like Destroyers and Battlecruisers will receive lower speed bonuses than their prop modules would state.
