Guidance thruster

Guidance thrusters are starship components located each of a ship's nacelles. These components appear to be separate in function from a starship's main thrusters.

The Jem'Hadar fighter discovered by the crew of Deep Space 9 on Torga IV in 2373 was found in excellent condition, save for a crushed guidance thruster – or comparable Dominion component. During a later engagement with the USS Centaur, the Jem'Hadar ship was hit and lost one of its guidance thrusters. 

While preparing for Operation Return in 2374, the USS Cortez was forced to fall back for repairs after having a continued problem stabilizing the guidance thrusters in the ships port nacelle.
