What impact did the attacks on the munitions factories in Iran have?

The pro-reform newspaper Ham Mihan reported on the explosions in Isfahan, a city with an important air base and military sites, including one of those bombed by the United States in the 12-day war between Israel and Iran. The Fars news agency, close to the Revolutionary Guard, mentioned that the attacks targeted 'two residential areas', without providing further details. The Israeli army stated that it has completed a 'wave of large-scale attacks' in Iran, and the U.S. announced that it has affected over two-thirds of Iran's munitions factories. The head of the U.S. Central Command, Admiral Brad Cooper, stated that the attacks have damaged or destroyed most of Iran's military production facilities. Although satellite images confirm the attacks, Iran has not acknowledged any material losses.
