Impulse Drive
Impulse Drive improves movement across your fleet.
Quick stats
| Effect at level 1 | Bonus |
|---|---|
| All ship speed | +18% |
| All ship deuterium consumption | +6% |
Drive bonuses add to base speed. Actual travel time depends on distance, selected speed and the slowest ship. Fuel penalties also follow tier progression, not a fixed amount at every level.
Cost and access
Available from level 0 without a lab or research prerequisite. Level 1 costs 38 base RP; later levels grow exponentially before any other-domain tier surcharge. The Research screen shows the current quote and saved funding.
Purchase a completed level immediately with RP, or use automatic investment. Metal, crystal and deuterium are not research payments in 3.0. Physical Research Labs increase RP income, not purchase speed.
Each fifth level adds another initial amount before compounding the bonus itself by 1%. See tier progression.
When to invest
Compare the displayed flight time and fuel quote before launch. A fast escort cannot make a slow capital ship travel faster. Buy the first level for its initial bonus, then weigh each additional percentage point against its rising RP price.
