Intelligence assessments indicate that Tehran likely added Russian-made weaponry to its missile stockpile during the eight-week truce.
Western allies believe Iran has probably incorporated newly built Russian arms into its arsenal and rebuilt significant portions of its missile capacity over the two-month ceasefire. This would provide the Islamic Republic with the capability to retaliate at near full strength should hostilities resume.
Intelligence evaluations suggest Tehran now possesses roughly three-quarters of the munitions it held prior to the war and can readily expand that amount further. One assessment noted this includes unspecified Russian missiles that were likely manufactured within the last year.
Russia’s Ministry of Defence did not reply to a request for comment.
US President Donald Trump stated last week that Iran had only 21 to 22 per cent of its missiles remaining.
Intelligence estimates from March reported that Iran had approximately 60 per cent of its pre-war missile inventory available amid a US and Israeli air campaign aimed at crippling its long-range strike capability.
Between February 28 and April 8, when the ceasefire began, Iran launched over 1,850 missiles across the region and at least twice as many basic Shahed-type cruise missiles.
During the first month of the war, the US and Israel estimated they had destroyed roughly two-thirds of Iran’s launchers. US Defence Secretary Pete Hegseth stated in mid-March that the regime’s offensive capability had been diminished by 90 per cent.
