Rocket — Factorio Production Calculator
Rocket is crafted in the assembling machine in 4 seconds, producing 1 per craft from 1 × Explosives, 2 × Iron plate. At 60 per minute you need 8 assembling machines, and the chain behind it draws on 4 raw resources: water, petroleum gas, iron ore, coal.
Production chain for 60 Rocket / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Iron plate | 120 | 6.4 | Furnace |
| Rocket | 60 | 8 | Assembling machine |
| Explosives | 60 | 2 | Chemical plant |
| Sulfur | 30 | 0.25 | Chemical plant |
Raw materials
| Resource | Per minute |
|---|---|
| Water | 750 |
| Petroleum gas | 450 |
| Iron ore | 120 |
| Coal | 30 |
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 recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 4 s | 1 | Explosives × 1, Iron plate × 2 |
What the whole chain needs
60 rockets per minute pulls in 3 intermediate products, and the whole tree comes to 17 machines across 3 machine types, fed by 4 raw resources. 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 750 per minute, which is 0.83 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.

FAQ
How many assembling machines do I need for 60 rockets per minute?
8 assembling machines. One at standard speed produces 7.5 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 take?
At 60/min the chain consumes 750 water per minute, 450 petroleum gas per minute, 120 iron ore per minute and 1 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is rocket needed for science packs?
Not directly. It feeds Explosive rocket, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
