How Many Rockets for a Stone Floor?
4 rockets
— or 3 from the soft side
4 rockets destroys a Stone Floor (500 HP) from the hard side. That's 5,600 sulfur once you count the gunpowder, and about 20s to place.
Timed Explosive Charge is cheaper for this.
2× Timed Explosive Charge costs 4,400 sulfur against 5,600 for 4 rockets — a difference of 1,200 sulfur per stone floor. If you've already got the rockets, use them; if you're farming from scratch, don't.
What 4 rockets costs
These are full craft costs — the sulfur figure includes everything that goes into the gunpowder, which is why it's bigger than the recipe on the item page suggests. Sulfur is the number that actually matters, because it's the thing you farm.

Frequently Asked Questions
How many rockets for a Stone Floor in Rust?expand_more
4 rockets to destroy a Stone Floor from the hard side — that's 5,600 sulfur once you count the full gunpowder chain. From the soft side (inside face) it's 3, because the interior takes more damage per hit.
What's the soft side of a Stone Floor?expand_more
The soft side is the interior-facing face — the side you see from inside the base. It takes roughly 34% less to break, so 3 rockets instead of 4. If you can get an angle on the inside face through a doorway or window, take it. On a wall, the soft side is the one without the visible seams.
Are rockets the cheapest way to raid a Stone Floor?expand_more
No. Timed Explosive Charge is cheaper on sulfur for this target — 2× costs 4,400 sulfur versus 5,600 for 4 rockets. That said, cheapest isn't always right: rockets may be faster to place or already in your base, and sulfur you've already farmed is a sunk cost.
How much sulfur is 4 rockets?expand_more
5,600 sulfur, plus 7,600 charcoal and 584 metal fragments. That's the full craft cost including the gunpowder each rocket needs, not just the final recipe.
How long does it take to raid a Stone Floor with rockets?expand_more
About 20s of placement time for 4 — that's the deploy time, not the farming. The farming is the real cost, and it's why people check this number before they commit.
Amounts come from the same sourced raid chart as our raid calculator and every /raid/ page, so they can't disagree with each other — verified for the July 2026 wipe. Deployables and external walls are approximate; always test on your own server build. Sulfur includes the full gunpowder chain.
