Afterburner

An afterburner, when ignited, accelerates your spacecraft, thereby allowing it to reach a higher velocity and escape from capital ship turrets and run away from hostile sentry defenses. Afterburners can more than double your speed and can mean the difference between life and death in asteroid fields and combat.

The rate of acceleration is dependent on the type of spacecraft. While intercept fighters gain a faster speed using afterburners, bomber engines are less focused on reaching a high maximal speed, due to having more energy required to be diverted to shields and weapons.

Any ship using afterburners can typically be recognized even by distance without reading the target's speed on your HUD. When the afterburner is used, the engine glow changes color, often to a lighter saturation.

Increasing the energy diverted to engines also make afterburners recharge more quickly, while having no power on engines makes the afterburner not recharge.

Useful tips.

A good pilot knows when and how to manage engine power and afterburners. If you meet an ace pilot, do not ever expect to overtake him unless your craft is so much faster.

A standard technique when on a bombing run is to engage afterburners right before releasing your payload, giving your otherwise slow warheads a short initial speed boost, reducing chances of the bomb being intercepted and allowing you to clear the shockwave more easily.
