Rocket silo — Factorio Production Calculator
Rocket silo is crafted in the assembling machine in 30 seconds, producing 1 per craft from 1000 × Steel plate, 1000 × Concrete, 100 × Pipe, 200 × Processing unit, 200 × Electric engine unit. At 60 per minute you need 60 assembling machines, and the chain behind it draws on 7 raw resources: water, iron ore, petroleum gas, copper ore, heavy oil, stone, coal.

Raw materials
| Resource | Per minute |
|---|---|
| Water | 810,000 |
| Iron ore | 733,200 |
| Petroleum gas | 570,000 |
| Copper ore | 516,000 |
| Heavy oil | 180,000 |
| Stone | 60,000 |
| Coal | 24,000 |
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 silo recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 30 s | 1 | Steel plate × 1000, Concrete × 1000, Pipe × 100, Processing unit × 200, Electric engine unit × 200 |
What the whole chain needs
60 rocket silos per minute pulls in 17 intermediate products, and the whole tree comes to 121,234 machines across 3 machine types, fed by 7 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 810,000 per minute, which is 900 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 silo
No base-game recipe consumes rocket silo — 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 rocket silo is made from
- Steel plate — 1000 per craft
- Concrete — 1000 per craft
- Pipe — 100 per craft
- Processing unit — 200 per craft
- Electric engine unit — 200 per craft
FAQ
How many assembling machines do I need for 60 rocket silos per minute?
60 assembling machines. One at standard speed produces 1 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 silo take?
At 60/min the chain consumes 810,000 water per minute, 733,200 iron ore per minute, 570,000 petroleum gas per minute and 4 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
