U.S. intelligence assessments indicate Iran restarted drone production during its April ceasefire with the United States. According to a U.S. official, Iran could fully reconstitute its attack drone capability in as soon as six months and has exceeded timelines previously estimated by U.S. intelligence agencies. According to other CNN sources and Israeli Prime Minister Benjamin Netanyahu, China has provided Iran with components usable in missile production, which the Chinese foreign ministry denied. U.S. intelligence reports also indicate that Iran retained a large portion of its coastal defense cruise missiles after the fighting in March. U.S. Central Command commander Admiral Brad Cooper testified to the House Armed Services Committee that 90% of Iran's defense industrial base had been destroyed during the U.S. bombing campaign.

Russia is shipping drone components to Iran via the Caspian Sea, according to U.S. officials. Previously, Iran had provided drones and components to Russia using the Caspian Sea route. In August 2025, the Ukrainian military claimed to have sunk a vessel owned by Russian shipping company MG-Flot that was transporting Shahed drone components from Iran to the Russian port of Olya in the northwest corner of the sea. Iran also imports other goods, including food and agricultural products, from Russia through four ports on Iran's Caspian Sea coast. Israel struck a naval command center at the Iranian port of Bandar Anzali in March.

Iran has retained approximately 75 percent of its prewar inventory of mobile missile launchers and 70 percent of its missile stockpiles, according to a U.S. official. The official claimed there is also evidence that Iran has reopened nearly all of its underground missile storage facilities, repaired some missiles, and finished assembling missiles which had been in the process of production before the war. U.S. President Donald Trump claimed publicly that Iran retained only 18 or 19 percent of its prewar missile stocks.

U.S. intelligence assessments of the time required for Iran to build a nuclear weapon have remained unchanged from summer 2025 despite the recent U.S.-Iran fighting. Following the Iran-Israel war in June 2025 and the accompanying U.S. strikes on Iran's Esfahan, Natanz, and Fordow nuclear sites, U.S. intelligence agencies estimated the timeline to be one year. Before the June 2025 war, they had estimated it to be nine months. U.S. and Israeli attacks in the 2026 war focused on Iran's conventional military capabilities rather than its nuclear program, although Israel struck some nuclear targets.

International Atomic Energy Agency (IAEA) Director General Rafael Grossi said that the majority of Iran's uranium enriched to 60 percent purity is still at the Isfahan nuclear complex, although he cautioned that the IAEA has not been able to inspect the site since June 2025. The Agency has satellite images showing the effects of U.S. and Israeli strikes on Iranian nuclear sites, according to Grossi.

U.S. military and intelligence officials estimate that Iran retains approximately 40 percent of its arsenal of attack drones and more than 60 percent of its missile launchers following the U.S.-Israeli bombing campaign against it. Iran had access to half of its launchers at the time of the ceasefire, but subsequently recovered approximately 100 launchers that had been buried inside underground fortifications. Iran is also in the process of recovering buried missiles. Some U.S. assessments estimate that Iran could recover up to 70 percent of its pre-war stock of missiles.

The Islamic Revolutionary Guard Corps (IRGC) Aerospace Force purchased a remote-sensing satellite from China that it used to target U.S. forces during its war against the United States and Israel. The satellite was built and launched from China by a Chinese company, and then sold to the IRGC Aerospace Force after launch. To operate the satellite, the IRGC Aerospace Force was given access to ground-control stations operated by another Chinese firm. Iran may have used the satellite to collect targeting data for a March 14 strike on Prince Sultan Air Base in Saudi Arabia which damaged five U.S. refueling planes, as well as strikes on other U.S. bases in the region.

U.S. intelligence indicates that China is preparing to transfer man-portable air defense systems (MANPADS) to Iran, according to sources familiar with the intelligence reports. China would potentially route the shipments through a third country to obscure their origin. The Chinese Embassy in Washington denied the report.

Four sanctioned, Iran-flagged ships - Hamouna (previously Canreach), Barzin, Shabdis and Rayen - believed to be carrying the missile propellant precursor sodium perchlorate from China have docked at Iranian ports since the start of the war between Iran and the United States and Israel. Another vessel thought to be carrying sodium perchlorate, Zardis, was offshore near Iranian waters. All of the vessels departed from Gaolan port in Zhuhai, China, which contains some of China's largest chemical storage terminals. They were owned by Iran's state-owned shipping company, Islamic Republic of Iran Shipping Lines (IRISL). Most of the ships turned off their Automated Identification System (AIS) at some point during their journey, and two falsely reported their destination as Vietnam.

Four facilities used by Iran to manufacture ballistic missile propellant and at least 29 missile launch sites have been damaged by the United States and Israel since the start of the war, according to an analysis of satellite imagery by the Washington Post. The damaged production sites included military complexes at Shahroud and Parchin, where solid missile propellant is produced; Khojjir, which produces both solid and liquid propellant; and Hakimiyeh, which manufactures liquid propellant and missile launchers. Four experts interviewed by the Post assessed that Iran would be unable to produce short- and medium-range ballistic missiles until the facilities are repaired or replaced. Damaged launch sites included the Khorgu missile base on Iran's Gulf coast and the Imam Ali missile base in western Iran. Iran is estimated to possess approximately 30 launch sites in total.
