Delta Flyer II impulse thrusters

The Delta Flyer II's impulse thrusters engaged

An impulse thruster was the output manifold of an impulse-powered propulsion system. Ships known to possess impulse thrusters included Jem'Hadar fighters, Galileo-type shuttlecraft, Danube-class runabouts, and the Delta Flyer II. (Star Trek V: The Final Frontier; DS9: "Rocks and Shoals", "The Assignment"; VOY: "Drive")

The impulse thrusters aboard runabouts contained one or more magnetic constrictors. (DS9: "The Assignment")

The impulse thrusters aboard a class V planetary probe launched by USS Voyager in 2376 maintained that craft's orbit of Kelemane's planet for two hundred years before experiencing failure. (VOY: "Blink of an Eye")
