Explosive rocket — Factorio Production Calculator
Explosive rocket is crafted in the assembling machine in 8 seconds, producing 1 per craft from 1 × Rocket, 2 × Explosives. At 60 per minute you need 16 assembling machines, and the chain behind it draws on 4 raw resources: water, petroleum gas, iron ore, coal.
Production chain for 60 Explosive rocket / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Explosives | 180 | 6 | Chemical plant |
| Iron plate | 120 | 6.4 | Furnace |
| Sulfur | 90 | 0.75 | Chemical plant |
| Explosive rocket | 60 | 16 | Assembling machine |
| Rocket | 60 | 8 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Water | 2,250 |
| Petroleum gas | 1,350 |
| Iron ore | 120 |
| Coal | 90 |
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.
Explosive rocket recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 8 s | 1 | Rocket × 1, Explosives × 2 |
What the whole chain needs
60 explosive rockets per minute pulls in 4 intermediate products, and the whole tree comes to 37 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 2,250 per minute, which is 2.5 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 explosive rocket
No base-game recipe consumes explosive rocket — it is an end product. Once you build it, the chain stops here, which makes it a good target if you only want to size the sub-factory that feeds your mall.
What explosive rocket is made from
- Rocket — 1 per craft
- Explosives — 2 per craft
FAQ
How many assembling machines do I need for 60 explosive rockets per minute?
16 assembling machines. One at standard speed produces 3.8 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 explosive rocket take?
At 60/min the chain consumes 2,250 water per minute, 1,350 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.
