Atomic bomb — Factorio Production Calculator
Atomic bomb is crafted in the assembling machine in 50 seconds, producing 1 per craft from 10 × Processing unit, 10 × Explosives, 30 × Uranium 235. At 60 per minute you need 100 assembling machines, and the chain behind it draws on 6 raw resources: petroleum gas, copper ore, water, iron ore, uranium 235, coal.
Production chain for 60 Atomic bomb / minute

|---|---|---|---|
| Copper cable | 48,000 | 400 | Assembling machine |
| Copper plate | 24,000 | 1,280 | Furnace |
| Iron plate | 14,460 | 771.2 | Furnace |

| Sulfuric acid | 3,000 | 1 | Chemical plant |
| Plastic bar | 2,400 | 20 | Chemical plant |
| Advanced circuit | 1,200 | 240 | Assembling machine |
| Processing unit | 600 | 200 | Assembling machine |
| Sulfur | 600 | 5 | Chemical plant |
| Explosives | 600 | 20 | Chemical plant |
| Atomic bomb | 60 | 100 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Petroleum gas | 33,000 |
| Copper ore | 24,000 |
| Water | 18,000 |
| Iron ore | 14,460 |
| Uranium 235 | 1,800 |
| Coal | 1,500 |
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.
Atomic bomb recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 50 s | 1 | Processing unit × 10, Explosives × 10, Uranium 235 × 30 |
What the whole chain needs
60 atomic bombs per minute pulls in 10 intermediate products, and the whole tree comes to 3,277 machines across 3 machine types, fed by 6 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 33,000 per minute, which is 36.67 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 atomic bomb
No base-game recipe consumes atomic bomb — 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.

FAQ
How many assembling machines do I need for 60 atomic bombs per minute?
100 assembling machines. One at standard speed produces 0.6 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 atomic bomb take?
At 60/min the chain consumes 33,000 petroleum gas per minute, 24,000 copper ore per minute, 18,000 water per minute and 3 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
