How Many Rockets for an Armored Floor?
15 rockets
— or 10 from the soft side
15 rockets destroys an Armored Floor (2,000 HP) from the hard side. That's 21,000 sulfur once you count the gunpowder, and about 1m 15s to place.
Timed Explosive Charge is cheaper for this.
8× Timed Explosive Charge costs 17,600 sulfur against 21,000 for 15 rockets — a difference of 3,400 sulfur per armored floor. If you've already got the rockets, use them; if you're farming from scratch, don't.
What 15 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 an Armored Floor in Rust?expand_more
15 rockets to destroy an Armored Floor from the hard side — that's 21,000 sulfur once you count the full gunpowder chain. From the soft side (inside face) it's 10, because the interior takes more damage per hit.
What's the soft side of an Armored 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 10 rockets instead of 15. 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 an Armored Floor?expand_more
No. Timed Explosive Charge is cheaper on sulfur for this target — 8× costs 17,600 sulfur versus 21,000 for 15 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 15 rockets?expand_more
21,000 sulfur, plus 28,500 charcoal and 2,190 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 an Armored Floor with rockets?expand_more
About 1m 15s of placement time for 15 — 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.
