The New York Times:
When an explosion nearly razed Iran’s long-range missile research facility in 2011 — and killed the military scientist who ran it — many Western intelligence analysts viewed it as devastating to Tehran’s technological ambitions.
Since then, there has been little indication of Iranian work on a missile that could reach significantly beyond the Middle East, and Iranian leaders have said they do not intend to build one.
So, this spring, when a team of California-based weapons researchers reviewed new Iranian state TV programs glorifying the military scientist, they expected a history lesson with, at most, new details on a long-dormant program.
Instead, they stumbled on a series of clues that led them to a startling conclusion: Shortly before his death, the scientist, Gen. Hassan Tehrani Moghaddam, oversaw the development of a secret, second facility in the remote Iranian desert that, they say, is operating to this day.
