Nuclear facilities in Iran in the context of Nuclear program of Iran

The Iran–Israel war (13 June – 24 June 2025), also known as the Twelve-Day War, was an armed conflict in the Middle East. The war began when Israel bombed military and nuclear facilities in Iran in a surprise attack, assassinating prominent military leaders, nuclear scientists, and politicians, killing civilians, and damaging or destroying air defenses. Iran retaliated with over 550 ballistic missiles and over 1,000 suicide drones, hitting civilian population centers, one hospital and at least twelve military, energy, and government sites. The United States intercepted Iranian attacks, and bombed three Iranian nuclear sites on 22 June. Iran retaliated by firing missiles at a US base in Qatar. On 24 June, Israel and Iran agreed to a ceasefire under US pressure.

The war followed a decades-long proxy war. Iran has called for Israel's destruction, and armed Hamas in Gaza and Hezbollah in Lebanon. Following the October 7 attacks in 2023, both entered open conflict with Israel. In April 2024, Israel bombed Iran's consulate in Damascus, Syria, killing senior Iranian military officials. Direct conflict continued in April and October. Iran's nuclear program has caused international concern for over a decade. Israel considers it an existential threat. In 2015, under the Joint Comprehensive Plan of Action (JCPOA), six countries lifted sanctions on Iran, which froze its nuclear program. In 2018, US president Donald Trump unilaterally withdrew from the plan. Iran began stockpiling enriched uranium and largely suspended International Atomic Energy Agency (IAEA) monitoring. The day before Israel attacked, the IAEA declared Iran non-compliant with its nuclear obligations in a resolution put forward by the United States, United Kingdom, France, and Germany.

The Natanz Nuclear Facility (Persian: تأسیسات هسته‌ای نطنز), officially the Shahid Ahmadi Roshan Nuclear Facilities (Persian: تأسیسات هسته‌ای شهید احمدی روشن), is one of the nuclear facilities in Iran, which was built near Natanz for uranium enrichment. This center is part of Iran's nuclear program. The underground enrichment facility of this center is protected by a concrete shield with a thickness of approximately 7.6 m (25 ft).

According to the Iranian authorities, the gas centrifuges in this center were built 40–50 metres (130–160 ft) underground, for safety reasons. and also for being safe from "possible air attack".

On June 22, 2025, the United States Air Force and Navy attacked three nuclear facilities in Iran as part of the Iran–Israel war, under the code name Operation Midnight Hammer. The Fordow Uranium Enrichment Plant, the Natanz Nuclear Facility, and the Isfahan Nuclear Technology Center were targeted with fourteen GBU-57A/B MOP "bunker buster" bombs carried by B-2 Spirit stealth bombers, and Tomahawk missiles fired from a submarine. According to Trump, US F-35 and F-22 fighters also entered Iran's airspace to draw its surface-to-air missiles, but no launches were detected.

The attack was the United States' only offensive action in the Iran–Israel war, which began on June 13 with surprise Israeli strikes and ended with the ceasefire on June 24, 2025. It was the first U.S. attack on an Iranian target since the 2020 assassination of Qasem Soleimani, and on Iran's territory since a 1988 naval offensive.
