The Israeli military and the foreign intelligence agency Mossad assess that Iran rebuilt its military capacity faster than expected after the war began in 2026. In Tel Aviv, the renewed acceleration of ballistic missile production is viewed as a serious threat to Iran’s military capacity.
Iran’s missile production accelerates again
Israeli defense officials say that Iran was able to resume production of missiles and other strategic weapons despite suffering heavy damage in attacks targeting its defense industry. The officials assess that Iran developed unexpected methods to rebuild some of its military capabilities.
In Israel, it was believed that attacks in October 2024 targeting Iran’s ballistic missile program and critical military-industrial facilities would disrupt production for at least a year. Following the attacks in 2025, it was also argued that Iran’s missile capacity had been set back by several years.
Arsenal estimated to have reached 2,500
Iran’s ballistic missile arsenal is estimated to have stood at approximately 1,300 in June 2025 and to have reached about 2,500 in February 2026. These figures shift the focus toward how quickly Iran was able to rebuild its production capacity, rather than the number of missiles it had left after the war.
If Iran regains the capacity to produce between 100 and 300 ballistic missiles per month, its arsenal could approach its 2025 level by early or mid-2027.
Israel monitors Iran’s capacity
Assessments of how quickly Iran is rebuilding its military capacity could affect Israel’s long-term strategy toward Tehran. The Israeli military continues to monitor Iran’s efforts to rebuild and develop its military capabilities.
Israeli military officials say they will not disclose exact figures or detailed assessments of the pace at which Iran is renewing its capacity for operational reasons.
