Fitting Modules and Rigs Guide
This guide describes the various types of modules and rigs that can be inserted into your ship slots, in summary form. For general advice on how best to select the right modules or rigs for your ship, see this article on Fitting Guidelines.
Rigs
All types of rigs except electronics and energy grid rigs have particular drawbacks associated with them. These penalties are reduced by training more levels in the associated rigging skill: the amount of speed reduction caused by armor rigs, for example, is lessened (though never completely eliminated) by your Armor Rigging skill

Ambit Extension: This rig increases turret accuracy falloff.
Burst Aerator: This rig increases turret rate of fire.
Collision Accelerator: This rig increases turret damage.
Discharge Elutriation: This rig decreases turret capacitor use. (Note that there is no Discharge Elutriation rig for projectile turrets, because they use no capacitor in the first place.)
Locus Coordination: This rig increases turret optimal range.
Metastasis Adjuster: This rig increases turret tracking speed.
High slots
Damage
These modules will deal direct damage to a target or multiple targets.
Doomsday Devices
Doomsday devices are extremely powerful weapons mounted on Titans. They deal 2 million points of racial type damage to a single target while using up 50 thousand units of the racial isotope to do so. They also have several drawbacks such preventing the titan from using a warp or jump drive for ten minutes after using the doomsday.
Hybrid Turrets
Hybrid turrets are the weapons used primarily by the Gallente. They use hybrid ammo that only deals thermal and kinetic damage.
Railguns
Long range hybrid turrets. They have longer range and higher rate of fire than other long-range weapon systems. They are moderately difficult to fit and are normally found on Gallente and some Caldari ships.
Blasters
Short range hybrid turrets. They have the most DPS of any type of weapon in game but also the least effective range. They are a bit easier to fit than railguns and are normally fitted on Gallente, and sometimes Caldari ships.
Laser Turrets
Laser turrets are the weapons used primarily by the Amarr. They use frequency crystals as ammunition and deal EM and thermal damage.
Pulse Laser Turrets
Short range Laser Turrets. They offer high damage potential while having decent range. They have fairly steep powergrid fitting requirements and are thus usually mounted only on Amarr ships.
Beam Laser Turrets
Long range Laser Turrets. They have the highest damage potential and best tracking but the least effective range than other long-range weapon systems. They have the steepest fitting requirements of any weapon system, and will thus normally be fitted only on Amarr ships, although the smaller beam lasers are much easier to mount.
Projectile Turrets
Projectile turrets are the weapons used primarily by the Minmatar. They use no capacitor to fire and are very versatile.
Autocannons
Short range projectile turrets. They have very good tracking and offer a flexible engagement range at the cost of DPS. Due to their versatility and low fitting requirements they will often be mounted on non-Minmatar ships.
Artillery
Long range projectile turrets. They have the highest volley damage but the poorest tracking of all long-range weapon systems. They have the second-highest fitting requirements after beam lasers and are thus rarely found on non-Minmatar ships.
Missile Launchers
Missile launchers are the primary weapon of the Caldari. Unlike turret-based weapon systems missile launchers have low powergrid needs but high CPU requirements. Man ships don't have enough turret hardpoints to fill a full rack of their preferred turret weapon, but will instead have launcher hardpoints.
"Short-Range" Launchers
"Short-range" bays refers to missile launchers using the short-range, high damage missiles, namely rocket launchers, heavy assault launchers, siege launchers and citadel torpedo launchers, as well as Assault Launchers. Except for rocket launchers, these short-ranged launchers have higher PG and CPU needs than their long-ranged counterparts (in contrast, long-ranged turrets have steeper fitting needs than their short-ranged counterparts). Assault launchers are a special case - they are cruiser-sized missiles bays that use light missiles. These launchers have significantly lower fitting needs than any other cruiser-sized weapon system, allowing more resources for other needs.
"Long-Range" Launchers
"Long-range" launchers refers to missile launchers using the long-range, low damage missiles, namely standard launchers, heavy launchers, crusie launchers, and citadel cruise launchers. Except for Standard Launchers, these launchers have lower fitting needs than their close-ranged counterparts.
Smartbombs
These weapons are area of effect weapons that hit anything within their activation range. Particularly effective against drones and poorly equipped frigates.
Drone Upgrades
These modules will increase the range of drones pr the number of drones you can control.
Drone Control Units
These modules allow the ship to control one extra drone each. Can only be fitted by carriers and supercarriers.
Drone Link Augmentors
These modules extend your drone control range.
Discussion
Drone control units are obviously only useful to carrier/supercarrier pilots. Drone Link Augmentors can be useful for drone boats and ships with nothing else to fit in their spare highslots.
EW
These modules will alter enemy ship caps and sensors.
Energy Neutralizers
These modules will dissipate the capacitor of an enemy ship by using your capacitor energy.
Energy Vampires
These modules will transfer energy from the enemy ship to your capacitor, if your target's capacitor percentage level is higher than your own.
Remote ECM Burst
These modules will emit an area of effect ECM burst, centered on a target whichhas a chance to break the lock of all ships within its range.
Discussion
Energy destabilizers are great tools for removing an enemy ship's ability to repair itself, while energy vampires are useful for energy hungry ships and as a defence against hostile energyz destabilization.
Logistics
These modules will restore cap, shields, armor, and hull to other ships.
Energy Transfer Arrays
These modules will transfer energy to the capacitor of an allied ship by using your capacitor energy.
Remote Armor Repair
These modules will repair the armor of an allied ship by using your capacitor energy.
Remote Hull Repair
These modules will repair the hull of an allied ship by using your capacitor energy.
Shield Transporters
These modules will repair the shield of an allied ship by using your capacitor energy.
Discussion
These 4 module classes form the backbone of remote repair (RR) and are invaluable in PVP fleet battles, level 5 mission runs, high level complexes, and wormhole operations as single ships cannot be expected to withstand the assault of an enemy fleet.
Tackling
These modules will prevent ship warping.
Interdiction Sphere Launcher
These modules fire interdiction spheres which prevent warping and cannot be countered by warp core stabilizers. These modules are for interdictors.
Warp disruption Field Generator
These modules create a field around a heavy interdictor which prevent warping within a radius, but also slows the heavy interdictor and makes them incur more damage (via an increased signature radius).
Mining Lasers
Mining lasers are used to harvest resources which include ore, ice, and gas.
Mining Lasers
Mining lasers can be fitted on any ship with turret hardpoints and are used to mine ore. The regular mining lasers are capable of mining any type of ore except for Mercoxit which requires a deep core miner.
Strip Miners
Strip miners are bulk ore extractors that can only be fitted on mining barges and exhumers. They feature significantly longer cycle times but much more impressive extraction amounts, resulting in an improved yield over mining lasers in the majority of cases. The regular strip miners can mine any ore except for Mercoxit, while the deep core miner can mine all types of ore.
Ice Harvesters
Ice Harvesters harvest ice and can only be fitted on mining barges and exhumers.
Gas Cloud Harvesters
Gas cloud harvesters harvest gas from gas clouds. They can be fitted on any ship with turret hardpoints.
Siege Modules
Siege modules are specialized modules mounted to certain capital ships that give them unique, very powerful properties, but at the cost of several drawbacks, the most important of which is that the capital ship is immobile for the duration of the siege module's cycle.
Siege Module
These are used by Dreadnaughts to enter siege mode which massively increases their DPS, but makes them immobile, among other factors.
Misc
These modules did not fit into the above categories.
Auto Targeting
These modules will target for you.
Cynosural Field Generator
These modules will create a cynosural field that will allow capital ships to enter a system. Be careful, as using the cyno field generator will leave your ship immobile for ten (10) minutes.
Cloaking
These modules will make you invisible unless you use a module or warp, or come within 2km of something. The cloak for recon ships and covert ops ships will not decloak for warp.
Gang Assist Modules
These modules will give bonuses to fleet members. They can only reasonably be equipped to battlecruisers.
Salvager
These modules will salvage loot from wrecks.
Scan Probe Launchers
These modules will launch scan probes to allow you to explore.
Tractor Beams
These modules will bring cargo containers and wrecks to your ship.
Triage Module
The triage module greatly increases a carrier's ability to provide assistance to a fleet while making it immobile, among other factors.
Industrial Core
The industrial core allows the Rorqual to compress ore.
Discussion
Auto targeting is a waste of a slot, and dangerous to boot as you want to be able to target manually. Cyno field generators would be best used on an alt in a frigate (that you don't mind losing, because as soon as the cyno field is created, everyone in the system knows where you are). Cloaking is invaluable for scouts. Tractor beams and salvagers can greatly increase the income from a lvl 3 or 4 mission.
Mid Slots
Capacitor
These modules will restore capacitor energy.
Capacitor Batteries
These modules will increase your total capacitor (and subsequently capacitor regen, as total capacitor and capacitor regen time are independent).
Capacitor Boosters
These modules will replenish your capacitor while expending a charge that you must carry (like ammo).
Capacitor Rechargers
These modules will increase your capacitor recharge time with no penalty.
Discussion
Boosters are generally preferred for large ships in PVP in the event of capacitor neutralizing. For your exact needs, experimenting in EFT will show which will serve you best.
Damage Supplements
These modules will increase DPS.
Tracking Computers
These modules will increase your optimal range, falloff range, and tracking speed.
Tracking Links
These modules will increase an allied ship's optimal range, falloff range, and tracking speed.
Drone Upgrades
These modules will increase the speed and tracking of drones.
Omnidirectional Tracking Links
These modules increase the optimal range and tracking of your drones.
These modules increase the MicroWarpDrive speed of your drones(their speed when they are flying around, not when they are orbiting & attacking).
EW
These modules will decrease enemy DPS, increase the enemy's incurred DPS, and prevent the opposite from happening.
ECM
These modules will make it difficult for an enemy ship to lock targets. They come in five varieties to coincide with the four sensor types and a multispectral.
ECM Bursts
This is essentially the same as ECM but affects all targets in a given radius.
ECCM
These modules protect against ECM.
ECCM, Projected
These modules protect ships that you use this module on, against ECM.
Remote Sensor Boosters
These modules increase the targeted ship's sensor range and locking speed.
Remote Sensor Dampeners
These modules decrease the targeted ship's sensor range and locking speed.
Sensor Boosters
These modules increase your sensor range and locking speed.
Target Painters
These modules increase the signature radius of enemy ships, increasing the damage they incur when hit.
Tracking Disruptors
These modules decrease the tracking speed of enemy turrets.
Discussion
EW has its own full discussion and class, so I won't be going into detail here.
Propulsion
These modules will increase a ship's velocity.
Afterburners
These modules will increase your velocity by roughly 120% while using some capacitor.
Microwarpdrives
These modules will increase your velocity by 500% while increasing your signature radius by 500% and a significant use of capacitor.
Shield Tanking
These modules will restore, extend, or increase the resistance of your shields.
Shield Boosters
These modules will repair your shields. Boost amplifiers are also in this category and they serve to increase the amount of shield repaired by a shield booster.
Shield Extenders
These modules will increase your total shield amount while increasing your signature radius (consequently increasing the damage incurred).
Shield Hardeners
These modules will increase your shield resistances while using a small amount of capacitor.
Shield Rechargers
These modules will increase your shield regeneration without penalty.
Shield Resistance Amplifiers
These modules will increase your shield resistances and uses no capacitor.
Discussion
You generally don't want to fit more than a single booster, as the cap drain will be quite high. Instead use a size-appropriate (or oversized) shield booster matched with a shield boost amplifier. Shield extenders are great for increasing a passive tank (remember that total shield and time to recharge are independent, so as you increase total shields you increase shield regeneration rate) but can work against you if they increase your signature radius too much. Finding a proper balance between shield extenders, shield hardeners, and shield rechargers is essential for a passive shield tank. Shield hardeners are strongly preferred to shield resistance amplifiers as the resistance increase is much greater and the capacitor drain is minor.
Tackling
These modules will slow and prevent warping of enemy ships.
Stasis Webifiers
These modules will decrease an enemy ship's velocity.
Warp Jammers
These modules will prevent an enemy ship from warping (provided they do not have warp stabilizers to negate your jamming). Warp Scramblers have a base range of 7.5km, have a jamming strength of two and will also disable the microwarp drives of your target as long as the target is scrambled. Warp Disruptors have a base range of 20km,jamming strength of one, and use more capacitor than warp scramblers.
Misc
These modules did not fit into the above categories.
Hull Repair Systems
These modules will repair your structure.
Passive Targeting Systems
These modules will allow you to target a ship without them knowing.
Scanners
These modules will allow you to scan the composition of asteroids, ice belts, and gas clouds, as well as ship fittings and cargo.
Discussion
Passive targeting systems matched with ship scanners can be a great way to have an alt find the fittings of war targets. Hull repair systems are a great way to save money if you have hull damage and don't want to pay the repair fees.
Low Slots
Armor Tank
These modules will repair, extend, and increase the resistance of your armor.
Armor Hardeners
These modules will increase your armor's resistance a great deal while using capacitor.
Armor Plates
These modules will increase your armor's total strength while greatly increasing your mass.
Armor Repair Systems
These modules will repair you armor.
Energized Plating
These modules will increase your armor's resistance a moderate amount. Regenerative plating increases your armor by a percentage and does not affect your resistance.
Resistance Plating
These modules will increase your armor's resistance slightly for just a single MW of powergrid. Regenerative plating increases your armor by a percentage and does not affect your resistance.
Discussion
Hardeners are the ideal if you can support them, followed by energized plating and finally resistance plating. Armor plates are great for a buffer tank.
Capacitor
These modules will increase the recharge rate of your capacitor.
Capacitor Flux Coil
These modules will increase your capacitor recharge at the expense of total capacitor energy.
Capacitor Power Relays
These modules will increase your capacitor recharge at the expense of the amount of shield your shield booster restores.
Discussion
If you need capacitor and aren't shield tanking, power relays would serve you well. If you're actively shield tanking, you'll need to strike the right balance for you. Note that while flux coils increase your capacitor recharge rate by slightly more than power relays, they also decrease your capacitor capacity, and capacitor recharge rate is tied to capacitor capacity. This means that overall flux coils actually increase your recharge rate by less than power relays. Only use flux coils if you're actively shield tanking.
Damage Supplements
These modules will increase your DPS.
Ballistic Control Systems
These modules will increase your damage and rate of fire when using missiles.
Gyrostabilizers
These modules will increase your damage and rate of fire when using projectile turrets
Heat Sinks
These modules will increase your damage and rate of fire when using laser turrets.
Magnetic Field Stabilizers
These modules will increase your damage and rate of fire when using hybrid turrets.
Tracking Enhancers
These modules will increase your optimal range, accuracy falloff, and tracking speed when using any/all types of turrets.
EW
These modules will increase your targeting and reduce your susceptibility to ECM.
Signal Amplifiers
These modules will increase your total allowed targets, your maximum targeting range, as well as reducing time to lock.
Sensor Backup Arrays
These modules will increase your sensor strength.
Fitting
These modules will help you extend your power grid or CPU.
Auxiliary Power Controls
These modules will increase your powergrid as an absolute (ie. not as a percentage) so is useful for frigates and destroyers.
CPU Upgrades
These modules will increase your CPU without penalty.
Power Diagnostic Systems
These modules will increase your powergrid, as well as minor boosts to your capacitor and shield capacity and recharge.
Reactor Controls
These modules will increase your powergrid without penalty.
Discussion
If you need an increase in your powergrid and don't need as much as a reactor control provides, the bonuses of the power diagnostic system is a great perk. If you're in a frigate, you'll want to use an auxiliary power control, since a percentage bonus will not give you as great a power grid increase as an absolute 10-12MW.
Propulsion
These modules will increase your velocity and/or agility.
Inertial Stabilizers
These modules will increase your agility at the expense of signature radius.
Nanofiber Structures
These modules will increase your velocity and agility at the expense of structure.
Overdrive Injectors
These modules will increase your velocity at the expense of cargo space.
Comparison
Injectors increase only velocity and reduce your ability to carry ammo, inertial stabilizers will increase your signature radius (and consequently your incurred damage) for a bit of agility. Nanofiber structures on the other hand, will provide both velocity and agility (very comparable to each individually) at the expense of structure. And honestly if you've reached a point where your structure is being hit, it doesn't matter how much you have. For further discussion on speed modules refer to the Guide on Stacking and Speed modules
Shield Tanking
These modules will increase the regeneration of shields.
Shield Flux Coils
These modules will increase shield recharge at the expense of shield capacity.
Shield Power Relays
These modules will increase shield recharge at the expense of capacitor recharge.
Comparison
Power relays are great for passive shield tanking on minmatar, as projectile weapons require no capacitor. Flux coils will deliver less recharge than they state, because of their reduction of total shields (remember that recharge time is independent of shield capacity, so as shield capacity is reduced, so is shield recharge). So with that said, shield power relays are the way to go for a passive shield tank, but neither should be used for an active shield tank.
Misc
These modules did not fit into the above categories.
Cargo Expanders
These modules will increase your cargo capacity at the expense of velocity. Ideal for haulers and salvage/loot ships.
Damage Controls
These modules will give you a great deal of resist for your hull, and minor resistance increases for your armor and shields at the expense of very minor cap use. Great module to extend your tank.
Ice Harvester Upgrades
These modules decrease ice harvester cycle time at the cost of CPU.
Mining Upgrades
These modules will increase mining laser yield at the expense of CPU.
Reinforced Bulkheads
These modules will increase your hull at the expense of velocity. You don't want to use these, as structure tanking is ill-advised and you can surely find a better use for the slot.
Warp Core Stabilizers
These modules counter warp jammers at the expense of targeting range and targeting speed. They are essential if you think you might get warp jammed and do not want to fight.
