Generic Impulse Engine.png

Impulse Engines are a type of starship equipment that increase a starship's normal flight speed, turn rate, and full impulse speed.

There are three basic types of Impulse Engines in the game:

All special Engines are variants of these three types.

Impulse Engine Modifiers[edit source]

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. The following 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]
Special Engines only (Fleet, Crafted/Upgraded, Reputation)
[+CRes] 10% resistance to Control Effects
[Damp] +33 Starship Drain Expertise[mods 4]
[Inertia] +10 Inertia Rating
[Pow]
[mods 5]
+3.8 Weapon Power Setting
+3.8 Shield Power Setting
+3.8 Auxiliary Power Setting
[Rrt]
[mods 6]
+20% Flight Speed when environmental hazards prevent use of Full Impulse.
[SecSpd] +X Sector Space Travel Speed
All Epic Impulse Engines
[SedSpd-2] +X×2 Starship Impulse Expertise
+X×2 Sector Space Travel Speed
Mark level of item X =
Mk I 1.9
Mk II 2.5
Mk III 3.1
Mk IV 3.75
Mk V 4.4
Mk VI 5
Mk VII 5.6
Mk VIII 6.25
Mk IX 6.9
Mk X 7.5
Mk XI 8.1
Mk XII 8.75
Mk XIII 9.4
Mk XIV 10


  1. Can appear twice on one engine, though Fleet Engines and some special engines have 3 or more innate or added [Spd] mods. 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.
  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 Fleet Engines.
  6. Integrated into Dynamic Reroute Impulse Engines, and can be found on Jem'Hadar Combat Impulse Engines [Rrt].

Uncommon endinges will have one modifier, Rare will have two, and Very Rare will have three, Ultra Rare will have four. The sum between X modifier value and the same basic deflector stat will be rounded.

An Uncommon Impulse Engine 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.

Special Impulse Engines[edit | edit source]

Numbers taken from a level 60 character with no skill points spent, no traits slotted, no equipment but the shield, 50 shield power, and no specializations affecting item stats.

Fleet Engines[edit | edit source]

Main article: Fleet Engines

Reputation Engines[edit | edit source]

The following are reputation set engines. Note that flight speed and full impulse scale with Mark level; the stats below are for Mk XII items. Mk XIII adds +1.5 Flight Speed, just like a [Spd] modifier. Full impulse boosts (both innate and from mods) add 16.5 at Mk XII and 19.5 at Mk XIII. Stats using an X multiplier also scale as the item increases in Mark level, shown in the table above.
