President Donald Trump informed that the United States have attacked three nuclear sites of Iran, joining Israel’s efforts to target the Islamic Republic’s nuclear facilities as the conflict enters its second week.
Calling the strikes “very successful,” Trump claimed that the US hit the Natanz, Fordo and Isfahan sites, with Fordo being one of the most important sites.
Here’s everything to know about Iranian nuclear sites mentioned by Trump and their importance to Iran’s nuclear program —
Natanz enrichment facility
Iran’s nuclear facility at Natanz, located some 220 kilometers (135 miles) southeast of Tehran, is the country’s main enrichment site and had already been targeted by Israeli airstrikes. Uranium had been enriched to up to 60% purity at the site — a mildly radioactive level but a short step away from weapons grade — before Israel destroyed the aboveground part of the facility, according to the U.N.’s nuclear watchdog, the International Atomic Energy Agency.
Another part of the facility on Iran’s Central Plateau is underground to defend against potential airstrikes. It operates multiple cascades, or groups of centrifuges working together to more quickly enrich uranium. The IAEA has said it believes that most if not all of these centrifuges were destroyed by an Israeli strike that cut off power to the site.
The IAEA said those strikes caused contamination only at the site itself, not the surrounding area.
Iran also is burrowing into the Kūh-e Kolang Gaz Lā, or Pickax Mountain, which is just beyond Natanz’s southern fencing. Natanz has been targeted by the Stuxnet virus, believed to be an Israeli and American creation, which destroyed Iranian centrifuges. Two separate attacks, attributed to Israel, also have struck the facility.
Fordo enrichment facility
Iran’s nuclear facility at Fordo is located some 100 kilometers (60 miles) southwest of Tehran. It also hosts centrifuge cascades, but isn’t as big as Natanz. Its construction began at least in 2007, according to the IAEA, although Iran only informed the U.N. nuclear watchdog about the facility in 2009 after the U.S. and allied Western intelligence agencies became aware of its existence.
Buried under a mountain and protected by anti-aircraft batteries, Fordo appears designed to withstand airstrikes. Military experts have said it could likely only be targeted by “bunker buster” bombs — a term for bombs that are designed to penetrate deep below the surface before exploding — such as the latest GBU-57 A/B Massive Ordnance Penetrator bomb in the American arsenal. The roughly 30,000 pound (13,600 kilogram) precision-guided bomb is designed to attack deeply buried and hardened bunkers and tunnels.
The U.S. has only configured and programed its B-2 Spirit stealth bomber to deliver that bomb, according to the Air Force. The B-2 is only flown by the Air Force, and is produced by Northrop Grumman, meaning that Washington would have to be involved in such an operation.
Isfahan Nuclear Technology Center
The facility in Isfahan, some 350 kilometers (215 miles) southeast of Tehran, employs thousands of nuclear scientists. It also is home to three Chinese research reactors and laboratories associated with the country’s atomic program.
Israel has struck buildings at the Isfahan nuclear site, among them a uranium conversion facility. The IAEA said there has been no sign of increased radiation at the site.
Iran has several other sites in its nuclear program that were not announced as targets in the U.S. strikes.
