Slipstream Navigation vs Fold Space Drives
Comparing the Slipstream Navigation (Tier 3) and Fold Space Drives (Tier 4), both propulsion technologies in Starforge MMO. Use this to decide which to queue first when your research lab can only run one project at a time.
Research Comparison
| Attribute | Slipstream Navigation | Fold Space Drives |
|---|---|---|
| Tier | T3 | T4 |
| Research time | 15▼ | 48 |
| metal cost | 25,000▼ | 120,000 |
| crystal cost | 12,000▼ | 60,000 |
| gas cost | 5,000▼ | — |
| antimatter cost | — | 800▼ |
| dark matter cost | — | 500▼ |
| Effect | +30% travel speed | intra cluster instant travel: true |
▼ marks the lower resource / time cost. Cheaper isn't always better — weigh it against the effect each tech unlocks.
Slipstream Navigation
Pilots trained to ride gravitational slipstreams cut interstellar travel time by 30%.
Unlocks buildings: navigation academy
Requires: propulsion 2
Fold Space Drives
Fold space between two points for near-zero travel time within same star cluster.
Unlocks buildings: fold space node
Requires: propulsion 3, propulsion 5
Which Should You Research First?
The Slipstream Navigation is the lower-tier prerequisite step and typically comes first in the propulsion branch, opening the path toward Fold Space Drives.
