Electronic warfare resistance and remote assistance impedance are ship attributes that reduce the effectiveness of incoming electronic warfare and remote assistance. These attributes are most commonly found on capital ships, but most other ships do not have these attributes by default. However, ships without them can sometimes gain them through the use of certain modules.
Resistances and impedances
On a basic level, the difference between resistance and impedance is that resistance makes hostile effects (like electronic warfare) less effective, while impedance makes friendly effects (such as remote repair) less effective.
There are a variety of attributes that affects the effectiveness of electronic warfare and remote assistance.
| Type | Group | Effect |
|---|---|---|
| Electronic warfare |  Sensor Dampener Resistance Sensor Warfare Resistance [1]
|
Reduces the effect of hostile  Remote Sensor Dampeners.
|
| Remote assistance | Remote Assistance Impedance [2] Remote Electronic Assistance Impedance
|
Reduces the effect of Remote Sensor Boosters and  Remote Tracking Computers.
|
| Electronic warfare |  Weapon Disruption Resistance
|
Reduces the penalty from Weapon Disruption [3].
|
| Remote assistance |  Remote Repair Impedance Remote Logistics Impedance
|
Reduces the repaired amount from  Remote Hull Repairs, Remote Armor Repairs and  Remote Shield Boosters.
|
| Electronic warfare |  ECM Resistance
|
Additional chance to avoid being affected by ECM Jamming [4]
|
| Electronic warfare |  Stasis Webifier Resistance
|
Reduces the slowdown effect of hostile  Stasis Webifiers.
|
| Command Burst |  Electronic Hardening
|
Reduces the effect of hostile Remote Sensor Dampeners and Weapon Disruption [3].
|
| Electronic warfare |  Capacitor Warfare Resistance
|
Reduces the capacitor drained by hostile  Energy Neutralizers and  Energy Vampires.
|
Remote Logistics.
Examples
Below are some examples of ships, modules or scripts with such resistances and impedances:
 The Confessor and other tactical destroyers have the information in the Traits tab as it's not always applied to the ship depending on their tactical mode. |
 For ships like the Avatar and other titans, the effect is always there and can also be found in the Attributes tab. |
Understanding the values
As with many attributes or bonuses, it can sometimes be difficult to understand how their effects are calculated. In some cases (e.g. Remote Repair Impedance and Remote Logistics Impedance), differently-named attributes have identical effects.
Resistances
Resistance is often presented as a negative bonus value, ranging from -0 down to -100%. The value represents how much of the effect is removed, so a -70% resistance bonus reduces the effectiveness of electronic warfare by 70%. This attribute can sometimes be presented as a positive bonus value (for example in the traits tab of a tactical destroyer). The bonus works the same though, despite it being a positive number, in that the +66.6% resistance bonus reduces electronic warfare effectiveness (in this case, weapon disruption and sensor dampening) by 66.6%.
ECM Resistance works differently from other electronic warfare resistances, in that they give a chance at avoiding the effect of enemy ECM jammers. This unique function is based on the fact that a ship can't be partially jammed. An 
ECM Resistance bonus of 100% means they cannot be jammed.[1] ECM Resistance can best be understand as a flat "chance to fail" that is checked before anything else. A partial bonus of 50% would first roll the 50% chance of simply failing (resisting), and if the check is successful, then the attempt to jam will simply fail. If the check fails to block the jam, the jamming attempt would then proceed to check whether the ECM strength of the hostile jammer is enough to overcome the sensor strength of the target.[2]
Impedances
Impedance is also presented as either a positive (often in the case for ship's innate impedance values) or a negative bonus (commonly done for impedance bonuses from modules). If the value is a negative value, like a -60% impedance bonus, it means that any incoming remote assistance of that kind is reduced by 60%. If the value is a positive +80% impedance bonus it means that they will lose 80% of the positive effect of the remote assistance, in effect only gaining 20% of it.
Notes
- ^ Attempting to jam a ship with 100% ECM Resistance gives the jamming ship a message informing them of this fact, which is useful to verify that the target is a state of immunity (such as Triage).
- ^ This is currently a theoretical scenario described in the Reworking Capital Ships: And thus it begins! devblog, as there are currently no ECM Resistances bonuses less than 100% in the game - just 100% bonuses giving full immunity through Siege, Triage, Bastion, and Industrial Core modules.
