How many missiles does Iran have left? By George Grylls in The Australian.
At the beginning of the conflict with Israel and the US, Iran had about 2500 ballistic missiles that could be fired from the back of trucks or from underground silos, according to the Alma Research Centre, an Israeli think tank.
That has been reduced to about 1000 missiles, it estimates in a new report. …
From launching dozens of ballistic missiles a day at the start of the three-week conflict, Tehran’s firing rate has dropped significantly. Now Iran is attacking Israel with about 10 missiles a day, suggesting that nearly a month of US and Israeli airstrikes has reduced Tehran’s ability to carry out retaliatory strikes. …

Iran can build more than a hundred a month:
Alma assesses that at the end of the 12-day war last year Iran was left with about 1500 missiles, but in the eight months that followed it was able to manufacture another 1000.
Or at least they could before the US and Israeli air-forces went after their manufacturing capabilities.
