# Preliminary mass-properties report — Version 0.4

## Results

| Quantity | Result |
|---|---:|
| Dry docked mass | 50,542.0 kg |
| Dry CG X | 2.0775 m |
| Dry CG Y | -0.00006 m |
| Dry CG Z | 0.00006 m |
| Propellant capacity | 12,000.0 kg |
| Full-propellant mass | 62,542.0 kg |
| Full-propellant CG X | -0.0480 m |
| Components represented | 59 |

The dry configuration is slightly forward-biased because the docked Skimmer and forward modules remain installed. The aft propellant load moves the full-tank CG close to X = 0. Propellant management and transfer must keep the operational CG inside the control allocation established during Version 0.5.

Mass values are conceptual Class-IV allowances. They are not vendor quotations, certified weights or final design values. NX-calculated solid masses should replace these allowances progressively while preserving a reconciliation record.
