Sh1n reposted a report from @BenTzionMacales concerning activity at the underground facility in Khojir linked to Iran’s missile production program.

Excavation work to open a new entrance has been identified at the underground facility in Khojir, which is linked to Iran's missile production program, as part of ongoing rehabilitation and upgrades.

This activity is consistent with assessments that Iran is working to move production underground, allowing operations to continue in place of aboveground facilities that have yet to be restored
