[Combat Impulse Engines] are one of three types of Impulse Engines, each with their own particular specialty. Combat Engines are designed to provide maneuverability at low power, giving them the most thrust capability at low power levels. They are unable to fully utilize large power supplies, resulting in a low maximum speed and minimal gains from increasing power to engines.

Impulse engine modifiers[]

Some Impulse Engines may have additional modifiers that either increase existing bonuses or add new ones. Uncommon engines will have one modifier, Rare will have two, Very Rare three, and Ultra Rare four. All Epic Engines have [SecSpd-2] as their default fifth modifier, though this can be re-engineered into a different modifier. Below are examples of Impulse Engine modifiers. Some Engines and modifiers boost Skills by a certain amount, based on Mark level. Refer to the table above for these values.

Modifier Effect
[Aux] Thrusters: 25% speed when engines are disabled.
[Spd] +10% Flight Speed.[mods 1]
[Turn] +0.3 to Flight Turn Rate[mods 2]
[Full] +7.33̄ + 0.766̄×Mk to Full Impulse Flight Speed.[mods 3]
Crafted Engines
Available on Engines crafted from the R&D Engineering School.
Crafted mods cannot be rerolled via re-engineering.

This is the default Epic modifier for Impulse Engines.
The other must be obtained by re-engineering your Engine.

  1. Can appear twice on one engine, though Fleet Engines and some special engines have 3 or more innate or added [Spd] mods, and engines can be re-engineered to have more. After calculating the base speed for the Engine's Mark level, the game will add 10% for one [Spd] modifier, 20% for [Spd]x2, and so forth. Thus, final speed for standard Impulse Engines will be (7.5+0.375*Mk) + N*0.1*(7.5+0.375*Mk), where N is the number of [Spd] modifiers. This formula works up to Mk XII; Mk XIII items are treated as if they were Mk XVI (16), while Mk XIV items as if they were Mk XXIII (23); for Combat and Hyper-Impulse engines, respectively adding or subtracting 1 Mk level from the final formula will give you a close approximation.
  2. Engines have a base 4.5 Turn rate; one [Turn] modifier will give them 4.8, and two 5.1, regardless of Mk level. Can appear twice on one engine, though Fleet Engines and some special engines have 3 or more innate or added [Turn] mods, and engines can be re-engineered to have more.
  3. Can appear up to 4 times on one Engine. As with [Spd], Mk XIII acts like Mk XVI and Mk XIV like Mk XXIII, so Mk XIII [Full] adds 19.5, Mk XIV adds 24.8. The number displayed rounds to the nearest tenth. For example, [Impulse Engines Mk IV [Full]] would receive a bonus of 10.4.
  4. Does not scale with Mk level. Previously Starship Inertial Dampers.
  5. Integrated into Efficient Impulse Engines, and can be found on Elite Fleet Efficient Engines.
  6. Integrated into Dynamic Reroute Impulse Engines, and can be found on Jem'Hadar Combat Impulse Engines [Rrt].
  7. Found on: Integrated into:
  8. Can be found on Elite Fleet Protomatter Engines. This modifier gives 0.15% Shield Hardness per 1% of Throttle up to a maximum of 15% Shield Hardness at full throttle.

An Uncommon Combat Impulse Engines will have one modifier suffix, Rare will have two, and Very Rare will have three. Rare and Very Rare can have multiples of the same suffix, and stacked suffixes are added together, not multiplied.

Base Flight Stats[]

Turn Rate is mostly determinated by the type of ship so the values are not listed here.
