How to get Corps of Engineers

Research in Stellaris is drawn: each area offers 3 cards at a time, weighted by each technology's draw weight (here 50) and its weight modifiers. Tier 3 opens after 6 tier 2 technologies of the same area. As a rare technology it is drawn less often, and some rare ones only appear after an event, a relic or a special project.

In the game

The creation of a dedicated naval engineering corps will greatly benefit the construction of deep space defense platforms, decreasing building costs and increasing durability.

Corps of Engineers: questions

How do I get Corps of Engineers in Stellaris?

Research Star Fortress and Modular Engineering first (6 technologies in the whole chain); then Corps of Engineers can be drawn as one of the 3 engineering research options. It is a rare technology: its draw weight is low, and some are only offered after an event, a relic or a special project.

What does Corps of Engineers do?

It gives -15% Station Upgrade Cost and +25% Station Upgrade Speed.

What is the ID of Corps of Engineers?

The technology's ID is tech_space_defense_station_improvement. To get it with the console: research_technology tech_space_defense_station_improvement (Stellaris 4.5.2).

How much does Corps of Engineers cost?

6,000 engineering research before modifiers. In game the cost grows with empire size (+0.2% per point above the base, common/defines) and the galaxy's tech cost setting.

Source: common/technology/00_eng_tech.txt and localisation/english, Stellaris Cygnus v4.5.2 (9776). Base numbers before empire-size and difficulty modifiers.
