Elite: Dangerous/Engineers

Engineers can be used to improve various modules of your ships.

Each engineer must first be discovered through either public knowledge or via another engineer, and then unlocked by completing their requests.

Engineering Mechanics

Unlocking an Engineer

Each engineer has 3 prerequisites before they can be used:

• They must be discovered, either through public knowledge (first 5) or through another engineer (other 15)
• They must be contacted, by satisfying a first demand
• They must be unlocked, by satisfying a second demand

Once unlocked they remain usable forever, even if the demands are no longer satisfied, unless something else prevents accessing their planetary base (such as a bounty).

Using Blueprints

Engineers can work on different modules of a ship, with per-module capabilities ranging from grade 1 to grade 5. Each grade offers better upsides and worse downsides compared to the previous grade, and you can only go as high as your current unlock level with the engineer and the maximum grade of the engineer for that blueprint. To advance an engineers unlock level, you can use their blueprints, or in some cases perform other actions such as selling exploration data.

Each module that an engineer can work on will have various blueprints for it, with differing upsides and downsides, as well as experimental effects that can be added if the module supports it. Each blueprint grade has a different cost, with higher grades requiring more and rarer materials, but only ever one of a given material. Every time a blueprint of a given grade is used, the positive stats increase from the blueprints minimum towards its maximum, and the negative stats are set to the values shown on the blueprint.

In order to use a blueprint grade (other than grade 1), you must first get the stats of the previous grade to 70% of their maximum value, as well as have the appropriate engineer unlock level. This can be bypassed by engineering the module in version 2.4 once, in order to get the module to grade 5, and then converting to the new engineering system to start out at grade 5 directly.

Experimental effects are simple additions to a module that have a one-time cost, offer specific stat changes, can be applied regardless of the chosen blueprint, and carry over when advancing grades. These effects can work with the chosen blueprint to improve the positives, reduce the negatives, or do something else entirely.

List of Engineers

Below is a table showing all 20 engineers, how they can be discovered and unlocked, and what blueprints they have.

Blueprints shown in bold are the highest tier of that blueprint available. For Life Support this is G4, for all others this is G5.

Blueprints shown in bold and italics can only be obtained from one engineer, making them mandatory if you want to use that blueprint.

Whilst both Elvira Martuuk and Felicity Farseer lack a mandatory blueprint, they are the only two engineers offering the same G5 blueprint. This makes either one of them mandatory.

Marco Qwent is one of two unimportant engineers, only needed as a stepping stone to get other engineers.

Colonel Bris Dekker is the only engineer that doesn't need to be unlocked, as they offer no mandatory blueprints and no engineer is locked behind them.
