Decouplers & Separators

Learn to use Kerbal Space Program decouplers and separators, like the TR-18A and TT-38K, for efficient rocket staging and booster separation.

Decouplers (e.g., TR-18A Stack Decoupler) and Separators (e.g., TT-38K Radial Decoupler) are essential for staging. Decouplers separate parts stacked vertically, while separators push parts radially away from the main stack. They are crucial for shedding empty stages and boosters.

Ensure your decouplers have enough force to cleanly separate parts without colliding with the main vessel. Use them strategically to optimize your staging sequence and maximize the efficiency of your rocket. Fairings can also be decoupled to reduce drag once in space.
