Weapons Guide

DPS from Overcharged ≈ DPS from Short Range ≈ DPS from Rapid Fire. Each has their own drawback with basically the same result.

Glossary of Terms

Falloff	The distance at which a weapon’s damage starts to decrease. This varies by weapon.
Maximum range	The distance at which a weapon’s damage falls to zero. Also varies by weapon. Just because a weapon can fire out to a certain range doesn’t always mean you can actually hit with that weapon at that certain range.
DPS	Damage Per Second – the damage you’ll be doing over time against a stationary target with continuous fire. Note that this does not always translate into real in-game experience.
sDPS	Sustained Damage Per Second – The damage you’ll be doing over time against a stationary target with continuous fire but also with reload pauses and distributor draw accounted for, for a slightly more realistic estimate. It still doesn’t always translate into real in-game experience.
Thermal Damage	Generated by all lasers, and partially by plasma accelerators and rail gun projectiles. Decreased by thermal resistance. Typically good against shields.
Kinetic Damage	Generated by all “cannons”, and partially by plasma accelerators and rail gun projectiles. Decreased by kinetic resistance. Typically good against unshielded hulls.
Explosive Damage	Generated by missile weapons and mines. Decreased by explosive resistance. Typically good against modules, utility mounts and hardpoints.
Absolute Damage	Generated by plasma accelerators only. Bypasses resistance. Typically good against shields, hulls, and modules.
TTD	Time to Drain – How long it takes you to empty the WEP Capacitor by continuously firing your current weapons. Does not always translate into real in-game experience.
Power Draw	How much power the weapon uses from your power plant, expressed in MegaWatts.
WEP Distributor	The capacitor that powers a closed loop cooling system whose job is to prevent your weapons from melting themselves with extended fire. An empty WEP Distributor results in Thermal Overload, where you can’t fire until WEP regains at least some energy.
Distributor Draw	How much energy (either per second or per shot) the weapon uses from your WEP Capacitor which is part of your Power Distributor, usually expressed in MegaWatts.
Jitter	The weapon slightly shakes with each shot, resulting in a degree of unavoidable inaccuracy.
Reload	Some weapons have a specific clip size. After that clip is empty there’s a pause in which the weapon cannot be fired during which the clip is refilled. Varies depending on the weapon and on your engineering choices.
Hardness	A value assigned to ship hulls to determine how much damage they take from various weapons. Higher hardness means that larger weapons (with higher Armor Piercing) are needed to do full damage against the hull.
Armor Piercing	A value assigned to weapons to determine how much damage they do to ship hulls. Higher armor piercing means that a weapon can do more damage against ships with higher hull Hardness.
Hitscan	The weapon instantly strikes the target as long as you are aiming correctly. You aim directly at your target.
Projectile	The weapon’s shots travel at a specific speed. That travel time that has to be taken into account when aiming, so you aim at a point in the target’s path. Faster shots are easier to hit with but generally have lower damage.
Breach Chance	The chance that a specific hit from a specific weapon causes damage to a module when that module is successfully hit. In most cases it’s a range of percentages that starts low when a target’s hull is 100% and gradually increases as the hull integrity is diminished from weapons fire. Killing modules requires both good aim and good luck.
Breach Damage	The damage done to a module when Breach Chance rolls “Yes”. This is always less than the listed damage of a weapon, although how much less depends on the type of weapon. Module Reinforcement Packages absorb Breach Damage to mitigate damage against the modules themselves.
Hardpoint Convergence Group	A set of hardpoints that, when outfitted with weapons with similar shot speed, are very likely to all strike the same module target with good aim.

What does Engineering Do?

Many weapons in Elite Dangerous are useful and effective as stock modules, but engineering helps to compensate for weaknesses in damage, range, distributor draw, and more. There are almost always trade-offs, so the basic effects are listed here. 

Engineering Recipe	Benefits & Drawbacks	Upside	Downside
Double Shot	Increased burst rate of fire, increased burst size, increased clip size, decreased maximum range. Frag cannons only.	Tons of damage all at once.	You run out of ammo very quickly.
Efficient	Lowers thermal load, lowers power draw, lowers distributor draw, moderate damage increase	Fire longer with less heat and do more damage. Hard to go wrong with this one.	There are higher damage options, longer falloff/range options, better AP options, etc. Weapons that are already efficient to begin with don’t benefit as much as you think.
High Capacity	Increases clip size, increases ammo capacity, small increase to rate of fire, increased power draw, increased module mass.	Can double your available ammo. Good for utility weapons for spreading experimental effects. Frag Cannons/Pacifiers can do high damage with this.	Not a good option for pure damage in most cases.
Focused	Increases maximum range, moderately increased falloff, increases Armour Penetration, increases thermal load.	Smaller weapons (low AP) do better damage against larger ships (high hull hardness).	Falloff still exists, so your damage is pretty low at the maximum range.
Lightweight	Lowers module mass, lowers power draw, lowers distributor draw, lowers module integrity	Gives mass sensitive ships something to shoot with.	Very low integrity – will break with one good hit. You’re leaving damage on the table in the exchange for the mass benefit, so judge carefully.
Long Range	Increases maximum range, increases falloff, increases power draw, increases module mass	Makes falloff nonexistent and range very long. Increases the shot speed of projectiles which makes it easier to hit.	Power draw can be punishing. Just because your weapon has increased range doesn’t mean you can hit at that range. Gimbals and turrets often fail to hit beyond 1.5 km due to their inherent aiming “wiggle”.
Overcharged	High damage increase, increases distributor draw, increases thermal load, decreases clip size.	Very high damage without the range limit from Short Range.	The distributor draw penalty means you run out of WEP sooner, which means you gain heat faster than you think. Decreases clip size for some weapons.
Rapid Fire	Increases rate of fire, decreases reload time, decreases distributor draw, decreases damage per shot, adds jitter	Tons of hits per second. Reload time bonus is great.	Per shot damage is lower, so single hits are lower DPS. Distributor draw is actually increased due to rate of fire. Jitter lowers your accuracy.
Short Range	High damage increase, increases thermal load, decreases range.	Very high damage. For most projectiles 2 km is the practical limit of effective aiming anyway, so you lose nothing with the max range limitation.	Heat can be damaging and will prevent consecutive shots or extended fire on some weapons unless compensated for. Your DPS is zero unless you can stay within the weapon range.
Sturdy	Increases module integrity, increases armour penetration, decreases thermal load, increases mass.	Takes heat out of the equation for some high heat weapons. It’s the go-to option when engineering Torpedos.	Other engineering options do most of these things better than Sturdy, or in ways that are more practical or useful.

Noteworthy Experimental Effects

Thermal Shock

Raises the target’s heat to a maximum of 90%. The target can raise it further themselves by firing weapons, using SCBs, boosting, etc.

At least two weapons with this effect are needed to get targets to 90% consistently, and you need to sustain fire to sustain the effect.

NPCs that overheat become slower, refuse to boost, and will only fire weapons with low heat. Basically, they’re sitting ducks.

Thermal Vent

Changes the beam’s heat per second value to a negative and multiplies it.

With enough venting you can cool ships to 0% heat, counteract heat from other weapons, eliminate heat from Shield Cell Bank spin-up, etc.

Recommended engineering: Long range to use at range, Short range to vent the most heat possible, Overcharged if you can sustain the distributor draw, lightweight if you want a low mass weapon with low distributor draw but “normal” heat venting.

You can also put thermal vent on efficient beams to take away their remaining heat load (and if you don’t need anything else on the beam), but don’t expect a lot of heat to be vented. Huge beams are the major exception.

Corrosive Shell

Increases damage done by 25% and increases armor piercing value by 20 for ALL weapons striking the hull while this is in effect.

Can be easily applied by a small high capacity multicannon or frag cannon, but it only works against hull. Save it for when shields are down.

There are very few situations where 25% more damage (plus whatever bonus damage you get for your increased AP) is worse than adding another weapon.

The only downside is that you have to devote a hardpoint to bestowing this effect, which can limit your hardpoint options on ships without many hardpoints, or without smaller hardpoints whose DPS won’t really be missed. Can only be bestowed by multicannons, frag cannons, and the powerplay module Pacifier.

Inertial Impact

Adds 50% damage to burst lasers as kinetic damage, but also adds a lot of jitter. There is no precision with this experimental at all.

If you have a ship that can stay in point blank range, you can do a lot of damage.

Regardless of primary engineering they’re pretty useless beyond 500m, so feel free to go with Short Range.

Large and Huge burst lasers have very slow rates of fire, so it’s difficult to get the damage out quickly when you need it.

High Yield Shell

Reduces damage by 35% and also reduces rate of fire, but you do damage in a sphere at the point of impact on the hull and can affect any module that the sphere overlaps.

You are still at the mercy of Breach Chance rolls, so it’s never a guarantee that you do module damage even if your aim is true.

Has been nerfed like crazy over the years due to its ability to take out multiple modules in one shot (including power plants!), but it’s still useful with large and huge cannons which have high inherent kinetic damage.

Dispersal Field

Works exactly like chaff…makes gimbaled and turreted weapons wave around aimlessly. The effect lasts a set time and can then be re-triggered by a subsequent hit.

If you have a chaff launcher and this experimental, you can use one while the other is on cooldown, thereby keeping the target’s gimbals and turrets in a near constant state of chaff effect.

Your shields will last longer because your enemies can’t reliably hit you. Just be careful for PA shots and fixed weapons that are immune to the effects of chaff.

Feedback Cascade

Striking a ship using an SCB during the initial 5 second spinup will “cancel” a portion of the shield restoration depending on the amount of damage done.

This means that you want medium rails, not small, if you want to prevent most of an SCB from happening.

Look for the (-) symbol to see if you hit correctly.

Phasing Sequence

You do 10% less damage in general, but a hit on shields causes 10% of your damage to be done as absolute damage to the underlying hull regardless of distance falloff.

If you’re going to go with phasing it’s best to use as many weapons with it as possible. A single pulse laser is not going to do enough damage to make phasing worthwhile.

There are two types of weapons that do well with Phasing Sequence…fast hitters and heavy hitters. Rapid fire pulse lasers are an example of fast hitters that do damage often enough for the phasing damage to add up quickly. Short Range Plasma Accelerators are an example of heavy hitters that do a high amount of damage all at once, so the 10% phasing damage is as large as possible.

Cytoscramblers are actually both fast and heavy hitters! You’ll also only ever use them for damage against shields, so no need to worry about them once the shields drop.
