Iran has resumed its production of ballistic missiles using stockpiled components and working in underground facilities, officials from the U.S. and Middle East familiar with the matter said. Despite heavy attacks on its missile sites and industrial facilities during the initial phase of the war, Iran has been busy assembling liquid-propellant missiles, which have to be fueled just before launch, as well as solid-propellant missiles, which can be stored ready to fire, some of the officials told The Wall Street Journal. Intelligence points to activity at several underground sites, including the Khojir missile facility in southeastern Iran, those officials said. Iran is also attempting to build new underground assembly points to avoid getting struck again, the daily quoted them as saying.

The US and Israel damaged a number of industrial facilities needed to produce missile components and missiles themselves, and the naval blockade has complicated imports of parts and ingredients for solid fuel. The renewed production underscores the difficulty of fully dismantling Tehran’s missile program, a goal of the war the US and Israel launched on Feb. 28. “When there are no bombings of the facilities, you can replace damaged infrastructure, and you can buy new components from other countries and store them in the facilities,” said Tal Inbar, a senior analyst at the US-based Missile Defense Advocacy Alliance. “You have to be extremely naive to think that Iran is not rebuilding its missile-production capabilities.” A White House official didn’t directly address the question of whether Tehran had resumed production of ballistic missiles but said that Iran’s nuclear facilities had been obliterated and its military forces severely degraded. “Iran is weaker now than ever before, and President Trump will never allow Iran to have a nuclear weapon,” the official said. Sean Parnell, the Pentagon’s chief spokesman, said the US had “destroyed up to 90% of Iran’s drone, ballistic missile, and naval industrial base” and “significantly degraded” Iran’s ability to launch missiles and drones.
