The SLS Core Stage is a large 1st stage rocket that is the first stage of the Space Launch System. All boosters in the game can connect to it, and its size is unmatched by any other part in the current version of Space Agency. It is much more effective when you attach the SLS Advanced Boosters or the SLS Solid Boosters to it.
- The SLS core module is unlocked in Mission 22.
