Minefields are a feature of a Star Fortress, a tier 3 station. All three flavours of orbital station have mines although there are some differences. The Doom also has a similar ship system, although to a more limited degree.
Low Tech[]
The Low Tech Star Fortress core has a hullmod that periodically spawns mines in clear areas not too close to ships nor asteroids. These mines have 250 hitpoints, 10 seconds of flight time and 2,000 HE damage.
Midline[]
The Midline (Mid Tech) Star Fortress core has a hullmod that periodically spawns mines in clear areas not too close to ships nor asteroids. These mines have 500 hitpoints, 20 seconds of flight time and 2,000 HE damage.
High Tech[]
The High Tech Star Fortress' Attack modules each have ship systems akin to the Doom's Mine Strike ship system, although with more range, holding 7 charges instead of 5 and recharging those charges faster.
