The Efficient Impulse Engines is an Impulse Engine that provides a scaling power bonus to weapons, shields, and auxiliary systems.

Item Description[]

These utility engines drain less power than standard engines, which effectively increases the power levels of all other ship systems (Bonus to Weapons, Shields and Auxiliary). The lower your power level in a given system, the more of a bonus you get. This engine grants no bonus if your power level in a given system is above 75.


The Efficient Impulse Engines is a reward for completing FED “Past Imperfect” (currently unavailable), KDF “Mars, the Bringer of War”, and ROM “Smash and Grab”.

Power Bonus[]

The amount of power supplied to each of the Weapons, Shields, and Auxiliary subsystems varies inversely based on your ship's power settings. The buff only works for power settings below 75 (+0), being more powerful at 25 (+2.5) and scaling between.
