The US intelligence community assesses that Iran currently possesses 1,500 to 2,500 missiles. US officials say this means that in the event of another full-scale war, Tehran would still possess a considerable capability to strike targets belonging to the US and its allies. US officials say this assessment is less credible because accurately tracking how many Iranian missiles are ready for launch or stored presents significant challenges. Nevertheless, officials say it is certain that Iran maintains a substantial missile stockpile. While the US and Israel destroyed some of Iran's missile production facilities, US officials say Iran is continuing to rebuild its missile inventory, albeit at a slower pace than before the war, currently relying primarily on previously stockpiled spare parts. In addition, Tehran possesses a large number of drones and short-range missiles.
Israeli military officials also assess that Iran possesses more than 1,500 ballistic missiles. However, due to the difficulty in determining the exact number, other officials in the Middle East offer different estimates. Simone Liddin, who served as Deputy Assistant Secretary of Defense for Middle East Affairs during Trump's first term, stated that even using the lower estimate of 1,500 missiles, Iran has replenished more than half of its pre-war estimated missile stockpile. She said that between the end of the war on June 12, 2025, and the outbreak of the current conflict in February 2026, Iran had fully rebuilt its missile stockpile.
Jim Ramson, a visiting fellow at King's College London and a former CIA analyst specializing in Iranian military capabilities, stated that it is difficult to estimate Iran's missile count due to Tehran's high level of secrecy regarding such information, Iran's reliance on multiple different missile manufacturers, and unknown factors, such as how many new missiles Iran can produce using underground stockpiles of finished components. He added that another factor increasing the difficulty of assessment is the inherent lack of clarity in pre-war estimates of Iran's missile stockpile.
