How close is Iran to a nuclear weapon?

As of 2026, Iran has enriched uranium to 60% purity and possesses enough material that, if further enriched to 90% weapons-grade, could theoretically produce a nuclear device within weeks — though weaponization and delivery system development would take longer.

What is Iran's breakout time?

Iran's breakout time — the period needed to produce enough weapons-grade uranium for one bomb — is estimated at less than two weeks based on current stockpiles, though building an actual deployable weapon would take significantly longer.

What are Fordow and Natanz?

Natanz is Iran's primary uranium enrichment facility, housing thousands of centrifuges in hardened underground halls. Fordow is a smaller but more deeply buried facility built inside a mountain near Qom, designed to survive airstrikes.

Iran's Nuclear Status in 2026

Iran has enriched uranium to 60% purity and accumulated enough material that a further step to weapons-grade 90% enrichment could be completed in a matter of weeks. The IAEA has documented this stockpile but has had limited access to Iranian facilities. The gap between enriched material and an actual deployable weapon remains significant, but it has narrowed substantially since 2018.
