Iran is producing 50 ballistic missiles a month, about half its prewar capacity, according to Western intelligence estimates reported.

An unnamed Western official who spoke to Bloomberg cited intelligence reports that found that though Iran’s conventional military was mostly destroyed by the joint US-Israel air campaign launched in February, it likely has at least 1,700 ballistic missiles left and is making more.

According to the report, despite accounts that the war left the US with a weapons shortage, it still has large stockpiles of precision-guided bombs and cruise missiles, but drawing on those supplies has depleted stores in other regions. It said Iranian missile launches at US forces and allies in the Middle East used up at least 1,000 Patriot interceptors. About 650 of those missiles, costing $4 million each, are produced each year. Bloomberg estimated that Iran fired over 4,900 Shahed drones and at least 2,200 ballistic missiles since the war started on February 28 with joint US-Israel attacks.
