Bomb Mode in Rainbow Six Siege: Defuser Rules, Timings and Win Conditions
Bomb is the core 5v5 attack and defense mode of Rainbow Six Siege and the only mode used in Ranked. Attackers try to disarm one of two bombs at a site by planting a defuser; defenders try to stop them by time or by elimination.
Rules and timings below follow the Rainbow Six wiki's Bomb page (edited 16 February 2026), checked against Ubisoft's season pages read on 2 November 2026.
The objective
Two bombs sit in the objective area, called the site, usually in neighboring rooms; some maps split a site across corridors or, on Consulate, across floors. The site pair is fixed, so when attackers find one bomb the other is revealed too. The bombs cannot be damaged, moved, EMP'd or hacked, but an IQ Electronics Detector can sense them.
The attackers' job is not to reach the bomb itself. One attacker is the defuser carrier, and the plant sequence on that device starts the disarm from anywhere inside the site room.
The defuser and its timings
| Step | Value |
|---|---|
| Plant sequence in Ranked | 7.5 seconds (0.5 s animation plus 7 s) |
| Time to disarm the bomb after planting | 45 seconds |
| Counter-defuse sequence | 7.5 seconds, must finish inside the plant timer |
| Defuser timer in Terrorist Hunt | 60 seconds |
During the preparation phase, a player on the attacking team can claim the defuser. If nobody does by the time operators lock, it goes to the operator who prioritizes it most, for example Thermite over Ash. The defuser drops if the carrier dies or is downed, and it must be picked up within about one meter. It cannot be destroyed, though it can be spotted by Solis's electronics sensor.
Win conditions
- Attackers win by eliminating all defenders at any point, or by planting the defuser and letting the plant timer expire without a counter-defuse.
- Defenders win by eliminating all attackers before the defuser is planted, by running out the round timer without a plant, or by completing a counter-defuse in time.
- No tie: if the last attacker and defender die together, the planted state decides it. Planted means attackers win; not planted means defenders win.
One rule matters most for tactics: after the defuser is planted, killing every attacker does not win the round for defenders. They must counter-defuse. A plant that began before the round timer ran out may finish after it; if the planter abandons it or is killed or downed before it completes, the attackers lose on time.
Where Bomb sits among 2026 modes
Ubisoft's season pages show how the playlist has widened without replacing Bomb. Siege X (10 June 2025, Operation Daybreak) added Dual Front, a 6v6 mode on the District map, where teams attack and defend at once by planting Sabotage Kits. Operation Silent Hunt (Y11S1, 3 March 2026) brought a limited-time 1v1 Arcade mode on Bomb rules, and Operation Split Fire (Y11S3, 1 September 2026) added a 3v3 Arcade mode, a Legend Division for Ranked and a Villa map update. Ranked 3.0 arrived on 2 June 2026 with five placement matches at the start of each season.
Tips that follow from the rules
- Take the defuser deliberately. Agree on the carrier in preparation, because the auto-assign picks by operator, not by who plays the entry.
- Attackers should clear the plant spot before starting the 7.5-second sequence, since leaving or dying cancels it.
- Defenders should place a player near the defuser's likely spot while it is planted, because the counter-defuse also takes 7.5 seconds and must end within the timer.
- Remember the hatch rule: a defuser planted on a hatch that is later destroyed gives defenders the round.

FAQ
Is Bomb the only mode in Rainbow Six Siege Ranked?
Yes, according to the Rainbow Six wiki. Quick Match, Unranked and Siege Cup also use it, and Dual Front and arcade modes are separate playlists.
How long does planting the defuser take?
In Ranked, 7.5 seconds: a half-second animation and a 7-second plant. After that the bomb takes 45 seconds to disarm.
Can defenders win after the defuser is planted?
Only by completing the counter-defuse in time. Eliminating all attackers after a plant does not end the round for them.
Is Dual Front a Bomb variant?
It is a separate 6v6 mode that borrows the plant idea with Sabotage Kits, introduced with Siege X on 10 June 2025.
