The Colonials can use fighters to sweep for mines. Each fighter can destroy 20 mines per turn. If the ship doing the mine sweeping has beam weapons then the ship will also use the beam weapons to destroy mines simultaneously.
The mine sweeping fighters can travel 100 light years from the carrier when on a mine sweeping mission.
Colonial ships that have fighters bays can build fighters in space using 3 tritanium, 2 molybdenum and 5 supply units per fighter.
The Colonies can build the Cobol Class Research Vessel and Lady Royale.
