Rocket fuel — Factorio Production Calculator
Rocket fuel is crafted in the assembling machine in 15 seconds, producing 1 per craft from 10 × Solid fuel, 10 × Light oil. At 60 per minute you need 30 assembling machines, and the chain behind it draws on 1 raw resources: light oil.
Production chain for 60 Rocket fuel / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Solid fuel | 600 | 10 | Chemical plant |
| Rocket fuel | 60 | 30 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Light oil | 6,600 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Rocket fuel recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 15 s | 1 | Solid fuel × 10, Light oil × 10 |
What the whole chain needs
60 rocket fuels per minute pulls in 1 intermediate product, and the whole tree comes to 40 machines across 2 machine types, fed by 1 raw resource. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 6,600 per minute, which is 7.33 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses rocket fuel
2 base-game recipes consume rocket fuel, sorted by how much each one takes:
- Satellite — 50 per craft
- Nuclear fuel — 1 per craft
What rocket fuel is made from
- Solid fuel — 10 per craft
FAQ
How many assembling machines do I need for 60 rocket fuels per minute?
30 assembling machines. One at standard speed produces 2 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does rocket fuel take?
At 60/min the chain consumes 6,600 light oil per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is rocket fuel needed for science packs?
Not directly. It feeds Satellite and Nuclear fuel, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
